You open Grammarly. Fix the grammar. Copy the text. Open Hemingway. Check the readability. Copy it back. Fix the sentences. Paste again.
That’s not a writing workflow. That’s an obstacle course.
Two tabs, two tools, two rounds of manual edits and errors still slip through the cracks. There is a better way. One tool fixes both grammar and readability simultaneously, with tracked changes you approve or reject. Here’s what it is and how the top options compare.
Key Takeaways
- Grammar and Readability Are Two Different Problems: Grammar tools catch errors. Readability tools flag sentence complexity. Most tools handle one but not both, which is why so many writers end up using two apps at the same time.
- Switching Between Tools Breaks Your Workflow: Every time you copy text between Grammarly and Hemingway, you interrupt your focus, risk losing edits, and add unnecessary time to every revision cycle.
- Orwellix Is the Only Tool That Fixes Both Automatically: Orwellix’s Agent Mode identifies grammar errors and readability problems in a single pass, rewrites them as tracked changes, and lets you approve or reject each edit, without leaving your document.
- Grammarly Misses Readability: No readability score, no sentence complexity detection, no autonomous rewriting. Grammarly is a grammar tool, not a clarity tool.
- Hemingway Misses Grammar: Hemingway highlights hard sentences but has no grammar checker in the free version and requires manual rewrites. There is no AI to fix what it flags.
Why Using Two Tools Is the Wrong Solution?
Every writer knows the frustration. You finish a draft. You run it through Grammarly and fix fifteen grammar errors. Then you paste it into Hemingway and discover eight hard sentences, four passive constructions, and a readability grade of 11. You fix those manually. Then you wonder if the grammar edits you just accepted changed any of the sentences Hemingway flagged.
So you go back. Check again. Fix again.
This is not a minor inconvenience. It is a broken process baked into the way most writing tools were designed. Grammar checkers and readability tools grew up in separate product categories, built by different teams with different goals. Nobody ever asked why a writer should need both.
The answer is: they shouldn’t.
The Core Problem with “One Tool for Each Job”
When you split grammar and readability across two tools, you create three problems.
First, you lose document context. When you paste text into Hemingway, it has no idea what Grammarly already changed. When you bring the Hemingway-edited version back, Grammarly rescans everything from scratch. No tool knows what the other one did.
Second, every fix is manual. Grammarly shows you a suggestion. You click accept. Hemingway highlights a sentence. You rewrite it yourself. There is no tool in this two-app stack that autonomously fixes anything, you apply every single change by hand.
Third, neither tool handles the other’s category. Grammarly’s free and premium tiers provide no readability score. Hemingway provides no grammar checking in its free version. You need both to cover both problems, which is the exact situation you were trying to escape.
What to Look for in a Grammar and Readability Tool
Before comparing tools, it helps to know what a great combined solution actually looks like. Freelancers with client deadlines should also read the best grammar checker for freelance writers comparison, because client voice and tracked edits matter as much as the score. These are the five capabilities that matter.
Grammar Checking
Real-time detection of spelling, punctuation, agreement errors, tense misuse, and incorrect word choice. The best tools catch these inline as you type, not in a separate report you generate after writing.
Readability Scoring
A Readability Grade Level score tells you the estimated reading level of your text. Grade 7–8 is the target for most web content. A tool that shows this score live, updating as you write, gives you constant feedback without interrupting the writing process.
Sentence Complexity Detection
Not all readability problems show up in a single score. The best tools highlight individual sentences that are too long, too dense, or too passive, so you know exactly where the problems are, not just that problems exist.
Autonomous Fixing
This is the gap most tools leave open. Grammarly and Hemingway both show you what’s wrong. Neither one autonomously fixes it. A tool with an AI agent that rewrites flagged issues as tracked changes and lets you approve or reject each one, replaces hours of manual editing with a single review pass.
Single-Document Workflow
The fix should happen inside your document. Not in a separate editor. Not by pasting into a chat window. Inside the document, in context, where the rest of your writing can inform each change.
The Best AI Tools for Fixing Grammar and Readability - Tested and Ranked
Each tool below was evaluated on grammar checking, readability scoring, autonomous fixing capability, and whether the workflow stays inside a single document.
1. Orwellix: Best Overall (Grammar + Readability + Autonomous AI Fixes)
Orwellix is the only tool on this list that handles grammar and readability in the same pass, autonomously, with tracked changes you control.
What It Does
When you open a document in Orwellix, the editor scores your readability in real time using the advanced readability Grade Level. The score updates with every sentence you write. You never need to check readability in a separate tool, it’s always visible.
Alongside the live score, color-coded highlights surface every issue in the document as you write:
- Red: Very hard to read - complex sentences that lose readers.
- Yellow: Hard to read - long sentences that need breaking up or simplifying.
- Purple: Grammar issues - errors that hurt credibility.
- Blue: Style issues - passive voice, adverbs, wordiness, qualifiers.
- Green: Spelling errors.
This is where Orwellix separates from every other tool. The highlights are not just diagnostics, they are actionable. Hover over a red or yellow sentence and click the “Simplify Using AI” button on each issue’s tooltip. The Agent takes over and rewrites that sentence in context, with the full document in view, and presents the change as a tracked edit. You accept or reject it. Nothing changes without your approval.
For grammar, the same principle applies. Errors are flagged in real time. You can fix them manually or run Agent Mode to handle the full document automatically.
Agent Mode: The Full-Document Fix
Agent Mode is the feature that makes Orwellix unlike anything else in this category. It is a full AI agent, not a grammar checker, not a readability highlighter, but an autonomous writer and editor.
Give Agent Mode a draft and it reads the entire document, identifies every grammar error and readability problem, and rewrites the document with tracked changes. Every change is presented individually. You scroll through, accepting what improves the writing and rejecting anything that doesn’t fit your voice. When you’re done, the document is cleaner, clearer and error-free, without you having to manually apply a single fix.
Agent Mode can also write from scratch. Open a blank document, describe what you need, and the agent researches the live web before writing directly into your editor. This makes Orwellix an end-to-end writing tool, not just an editing layer.
Ask Mode handles faster, targeted tasks: rewrite this section, adjust the tone, cut this paragraph to 50 words. Each Ask Mode session costs 1 credit. Agent Mode costs 2 credits per session.
Why It’s the Top Pick?
Every other tool on this list forces you to choose between grammar and readability or use two tools and manually apply every change yourself. Orwellix eliminates that choice.
The live readability score means readability is always visible. The color-coded highlights mean you see every problem, grammar and readability, in one place. Agent Mode means you can fix everything in a single autonomous pass and review tracked changes instead of writing rewrites from scratch.
No other tool here combines all of these in one document workflow.

- Agent Mode tracked changes work best when reviewed carefully, the AI is accurate but your judgment still matters.
2. Grammarly: Strong Grammar, Weak Readability
Grammarly is the most widely used grammar checker in the world. For catching grammar errors inline across Google Docs, Microsoft Word, and the browser, it is genuinely good.
What It Does
Grammarly catches spelling, punctuation, grammar, and style errors in real time through a browser extension or dedicated editor. On Premium plans, it flags passive voice and suggests tone adjustments.
Where It Falls Short
Grammarly has no readability score on standard plans. It does not score sentence complexity in real time. It does not highlight individual sentences by difficulty. It has no AI agent that autonomously rewrites your document. Every suggestion Grammarly makes requires a manual click to apply.
For grammar accuracy, Grammarly is a solid tool. For readability, it is not a readability tool. You still need a second app, which is exactly the problem this article is about.
At $30/month for Premium, you pay more than Orwellix Pro while getting less than half the capability. Orwellix includes grammar checking, live readability scoring, color-coded complexity highlighting, and autonomous Agent Mode fixes, all for $24/month.
Pricing
- Free (basic grammar). Premium: $30/month.
3. Hemingway Editor: Strong Readability, No Grammar
Hemingway Editor was built specifically for readability. It highlights hard and very hard sentences, flags passive voice and adverbs, and shows a readability grade level. For readability diagnostics alone, it does its job.
What It Does
Paste your text into Hemingway and it color-codes every sentence by difficulty level. Hard sentences turn yellow. Very hard sentences turn red. Adverbs turn blue. Passive voice turns green. A readability grade appears at the top of the screen.
Where It Falls Short
Hemingway is a diagnostic tool. It has no AI. It shows you 12 hard sentences and waits for you to rewrite all 12 yourself. Every single improvement is manual, which makes it slow for any document longer than a few paragraphs.
The free web version has no grammar checker at all. Grammar checking was added only in the paid Hemingway Editor Plus plan. The desktop app ($19.99 one-time) has no autosave on the web version, minimal updates in recent years, and no agent of any kind.
If you use Hemingway, you still need Grammarly or another grammar tool. You’re back to two apps. And you’re still doing every rewrite yourself.
Pricing
- Free (web, no save). Desktop app: $19.99 one-time. Hemingway Editor Plus: subscription with grammar features.
4. ProWritingAid: Grammar and Readability Reports (All Manual)
ProWritingAid offers deep analysis across grammar, readability, style, and structure. It generates over 25 different writing reports, including readability grade, passive voice frequency, sentence length variation, and consistency checks.
What It Does
Run a report in ProWritingAid and you get detailed analysis across dozens of writing dimensions. The readability report includes grade level, sentence length distribution, and passive voice percentage. The grammar check catches errors comparable to Grammarly. The tool is analytically thorough.
Where It Falls Short
ProWritingAid is a report generator, not an autonomous fixer. Every insight in every report requires manual action. There is no AI agent that reads your document and fixes issues as tracked changes. There is no live readability score updating as you type. There is no one-click simplification for hard sentences.
The interface is complex. New users spend significant time navigating tabs and reports rather than actually improving their writing. For writers who need fast, practical fixes on everyday content, the analytical depth becomes friction rather than value.
ProWritingAid handles both grammar and readability in theory. In practice, it shows you both problems and waits for you to solve them, which is exactly what the two-tool Grammarly-Hemingway stack does, just consolidated into one slow interface.
Pricing
- Monthly: $30/month. Annual: ~$10/month billed annually. Lifetime options available.
5. LanguageTool: Grammar Only, No Readability
LanguageTool is an open-source grammar and style checker available free in the browser and as a desktop app. It checks grammar in over 30 languages and flags common style issues.
What It Does
LanguageTool catches grammar errors, punctuation mistakes, word confusion, and some style issues. The premium plan expands checks significantly and adds paraphrasing suggestions. It integrates with browsers, Google Docs, and LibreOffice.
Where It Falls Short
LanguageTool has no readability scoring. There is no readability grade level, no sentence complexity detection, no difficulty highlights, and no AI agent for autonomous document editing. It is a grammar tool. Full stop.
For writers who need grammar checking in a language other than English, LanguageTool’s multilingual support is a legitimate differentiator. For anyone whose goal is fixing both grammar and readability in English content, it solves only half the problem.
Pricing
- Free (basic, 2,000-character limit). Premium: varies by plan. Open-source self-hosted version available.

The Real Cost of Using Two Tools
Writers who use Grammarly and Hemingway together often don’t realize how much time the two-tool workflow costs.
Here’s a realistic scenario. You write a 1,500-word blog post. You run it through Grammarly, there are 11 suggestions. You review and apply each one manually. That takes 8 minutes. You copy the text into Hemingway. There are 9 hard sentences and 3 very hard ones. You rewrite each manually, that’s another 25 minutes. You copy the text back into your original document. You notice the formatting broke. You fix that. Then you wonder if any of the Hemingway rewrites introduced a grammar error. You check again.
Total extra time: 40 minutes or more on a single draft, on top of the writing itself.
With Orwellix Agent Mode, the same draft takes a different path. You ask the Agent Mode. The AI reads the full document, identifies grammar errors and readability problems simultaneously, and creates tracked changes for every fix. You spend 10 minutes reviewing the changes, accepting the ones that improve the writing, rejecting the ones that don’t. Grammar and readability are fixed in a single pass. You never leave the document.
The time saving is real. So is the quality gain, because the AI fixes grammar and readability together, in context, each change informed by the full document rather than a decontextualized paste-in.
Why Context Matters When Fixing Both Problems at Once
This is the point most tool comparisons miss.
When Hemingway flags a hard sentence and you rewrite it manually, the rewrite doesn’t know whether the sentence follows a technical paragraph that justified its length, or whether the sentence contains a grammar error that should be fixed first rather than reworded. The tools are isolated. The fixes are isolated.
Orwellix Agent Mode reads the whole document before making any change. It knows what came before the hard sentence and what follows it. It knows which passive constructions are intentional choices versus which ones are just lazy drafting habits. It rewrites with context, which produces better output than any decontextualized tool can.
This is the advantage of an AI agent over a diagnostic dashboard. Dashboards show problems. Agents solve them, with judgment, in context, at document scale.
How to Fix Grammar and Readability in One Pass Using Orwellix
If you want to see this in practice, here’s the workflow.
Step 1: Open or Paste Your Draft
Create a new document in Orwellix or paste in an existing draft. The live readability score appears immediately. Color-coded highlights mark every grammar error, hard sentence, passive construction, and style issue.
Step 2: Run Agent Mode
Click Agent Mode and describe the task. Something like: “Fix all grammar errors and improve readability. Keep my voice and structure intact.” The agent reads the full document and creates tracked changes for every fix, grammar and readability addressed together in a single pass.
Step 3: Review Tracked Changes
Go through the changes one by one. Accept the fixes that improve the writing. Reject any change that doesn’t fit your voice or meaning. Nothing is applied automatically, every decision is yours.
Step 4: Check the Score
After reviewing, your live advanced readability score shows the new level. Remaining highlights show any issues you chose to keep. If the score is still higher than you want, use the “Simplify Using AI” button on individual sentences for targeted fixes.
That’s the entire workflow. No copying between apps. No manual rewriting of every flagged sentence. No re-checking whether the grammar edits introduced new readability problems.
Grammar vs. Readability: Why Both Matter Equally
Writers often treat grammar and readability as different tiers - grammar is essential, readability is optional. This is wrong.
Grammar errors damage credibility. A published piece with subject-verb disagreement, comma splices, or confused homophones signals carelessness. Readers notice. It erodes trust in both the writer and the content.
Poor readability damages comprehension. A grammatically perfect paragraph written at Grade 13 reading level with three embedded clauses and four nominalizations is technically correct, but most readers won’t finish it. They’ll scan to the end and leave without retaining the point.
Both problems have the same downstream effect: readers disengage. The difference is why they disengage. Grammar errors tell them the writer is sloppy. Readability problems tell them the content is too hard to bother with. Either way, the piece fails.
A tool that fixes only grammar solves half the problem. A tool that diagnoses only readability solves the other half. The only solution that fully works is one that handles both - automatically, in context, in a single pass.

Orwellix is the only tool that addresses grammar and readability in the same pass, with an AI agent that writes tracked changes you approve or reject, inside your document, without switching apps.
If you’ve been running two tools on every draft and manually applying every suggestion both tools generate, you now know there’s a better option. Start your 7-day Orwellix trial - full platform access, credit card required upfront but nothing charged for 7 days. Cancel before day 7 and your account converts to free, no charge. Don’t cancel and your chosen plan activates automatically.

Frequently Asked Questions (FAQs)
1. What is the best AI tool for fixing grammar and readability at the same time?
Orwellix is the strongest option for fixing both grammar and readability in one place. Its Agent Mode reads your full document, identifies grammar errors and readability problems simultaneously, and creates tracked changes for every fix. You review each change and accept or reject it individually. No other tool in this category combines live readability scoring, real-time grammar checking, sentence complexity highlights, and an autonomous AI agent that fixes everything in a single pass inside your document.
2. Why isn’t Grammarly enough for fixing readability?
Grammarly is a grammar tool. Its standard and premium plans do not include a readability checker, do not detect sentence complexity in real time, and do not highlight individual sentences by difficulty level. Grammarly’s suggestions are limited to grammar, spelling, tone, and style, it does not tell you whether your sentences are too long or too complex for your target audience. For readability, you still need a separate tool.
3. Does Hemingway Editor check grammar?
The free version of Hemingway Editor does not include grammar checking. Grammar and spelling checks were added only in the paid Hemingway Editor Plus subscription. Even with grammar checking enabled, Hemingway provides no AI agent, every rewrite is manual. Writers who use the free version of Hemingway still need a separate grammar checker, which puts them back in the two-tool workflow this article is designed to help them escape.
4. What does an AI agent actually do differently from a regular grammar checker?
A regular grammar checker flags problems and waits for you to fix them. An AI agent reads your full document, generates the fixes itself, and presents them as tracked changes you approve or reject. The difference in practice is significant. A grammar checker adds work to your editing process. An AI agent replaces most of that work with a review pass. Orwellix’s Agent Mode fixes grammar errors and readability problems in a single autonomous run, something no traditional grammar checker or readability tool does.
5. What is a good readability grade level for web content?
For most general-audience web content, blog posts, landing pages, email newsletters, a readability Grade Level of 6–8 is the target. Grade 9–10 is acceptable for technical or professional audiences. Anything above Grade 10 for a general readership is likely to result in higher bounce rates and lower engagement. Orwellix displays a live advanced readability score in the editor that updates as you write, so you always know your current readability level without running a separate check.
