Make your writing bold and clear with AI suggestions.
Writing
Hemingway Editor is the writing tool that has quietly been sitting in the browser tab of serious writers, editors, and communications professionals since 2013, doing one specific job better than any other tool on the market: telling you, in unambiguous colored highlights, that your sentences are too long, your writing is too passive, your vocabulary is unnecessarily complicated, and your paragraphs will lose the reader. Named after Ernest Hemingway's famously spare prose and built by the Long brothers — Adam and Ben — as a side project that turned into a decade-plus mainstay, Hemingway Editor is the anti-Grammarly. Where Grammarly is thousands of grammar rules and mechanical corrections, Hemingway is a small handful of readability principles applied ruthlessly. Where Grammarly whispers stylistic suggestions, Hemingway shouts at you with red, yellow, blue, green, and purple highlights.
What Hemingway Editor actually does, cleanly stated, is score your writing against a readability model, highlight every sentence that is hard to read (yellow) or very hard to read (red), flag every adverb, every passive voice construction, and every phrase with a simpler alternative, and give you a grade level score that maps roughly to what US school year could read the piece comfortably. It is a mirror for prose — not a grammar checker, not a spell checker, not a full editor. And in 2024-2026, Hemingway added a genuinely useful AI layer called AI Fix that will rewrite flagged sentences into cleaner versions on demand, turning the tool from a diagnostic into a diagnostic-plus-treatment.
The one-line positioning: Hemingway Editor is the tool you paste your draft into when you want to know, honestly, if a busy reader on a phone will actually get through it. It is not trying to make you a better writer in the abstract; it is trying to make this specific paragraph clearer, shorter, and more directly written. That job is narrow but universal. Every writer with an audience — whether they are drafting a marketing email, a landing page headline, a business memo, a Substack essay, or a shareholder letter — benefits from an honest readability read before they hit publish.
Hemingway has expanded beyond its original one-page web app. There is now a desktop app for Mac and Windows, an AI-powered plans tier, and a Chrome extension that puts the readability model inside Gmail, LinkedIn, Google Docs, and any other web text field. The core promise — ruthless readability feedback — is unchanged. What has changed is that the tool now offers to fix what it flags, which was the missing piece for a decade.
Hemingway Editor's product surface is famously narrow. The features that earn the subscription are the readability model itself, AI Fix, and the browser extension for in-place editing.
Readability highlights. The signature feature. Paste any text and Hemingway highlights every hard-to-read sentence (yellow), very hard-to-read sentence (red), passive voice construction (green), adverb (blue), and phrase with a simpler alternative (purple). The color system is fast to learn and hard to forget. You will never write another paragraph without half-consciously scanning for yellow.
Readability grade. Every draft gets a grade level — "Grade 8" means an average US eighth grader could read this comfortably. Most professional writing lands at Grade 6-10. Most academic writing lands at Grade 14+. The grade is not the goal — the goal is to match the grade to your audience, and Hemingway makes that legible.
AI Fix (2024+). The genuinely important recent addition. Click any flagged sentence, and Hemingway offers to rewrite it into a cleaner version — shorter sentences, active voice, plainer vocabulary. You keep, revise, or discard. This turns Hemingway from a diagnostic tool into a working editor. It is credit-metered on the paid plans, and it is the feature that makes the paid tier worth considering.
AI Sentence Structure and AI Passive Voice fixes. Targeted AI passes for the specific problems Hemingway flags. Instead of a full-document rewrite, you can ask the tool to fix only the passive-voice constructions or only the sentence-length issues while leaving the rest of your voice alone.
Chrome extension (Hemingway Everywhere). The extension puts Hemingway's readability engine into Gmail, LinkedIn, Google Docs, Notion, and any web text field. The highlights appear inline as you type or in a side panel on request. This is the feature that turns Hemingway from a "paste and check" tool into an ambient writing assistant.
Desktop app for Mac and Windows. A native desktop version with the same feature set, offline drafting, and clean export to markdown, DOCX, HTML, and PDF. Useful for writers who prefer a dedicated writing environment over a browser tab.
Publishing integrations. Direct publish to WordPress and Medium from the desktop app. Small feature that saves the "copy from Hemingway, paste into CMS, fix the formatting" round trip.
Formatting toolbar. Basic markdown-shaped formatting — headings, bold, italic, quotes, lists — enough for a working draft, not enough for a design-heavy document.
Word count, character count, reading time. Standard writing stats. Reading time in minutes is genuinely useful when you are writing to a specific length target.
What Hemingway deliberately does not do. No grammar checking (Grammarly's job). No spell checking beyond the browser's default (also Grammarly's job). No plagiarism detection. No SEO scoring. No collaborative editing. No version history. The narrowness is the feature.
Hemingway Editor's pricing has evolved from a simple one-time desktop purchase to a mixed model with a free web app, a paid desktop app, and AI-powered subscription plans.
| Plan | Price | What you get |
|---|---|---|
| Free (web) | $0 | Full readability highlights, grade level, no AI Fix, no save |
| Desktop app | $19.99 one-time | Native Mac or Windows app, offline, publishing integrations |
| Plus | $10/month | AI Fix credits, AI Sentence Structure, browser extension |
| Team | $15/user/month | Plus for teams with shared credits and admin |
The free web tier at hemingwayapp.com is the classic paste-and-check experience. Full readability highlights, grade level, adverb and passive-voice flags — all free, forever, no signup. If you just want the diagnostic, this is the entire product you need. It is the tier the vast majority of Hemingway users have been on for years, and it is not going anywhere.
The desktop app is $19.99 as a one-time purchase (no subscription for the classic desktop version). You get offline drafting, direct WordPress and Medium publishing, and a native app that does not depend on browser tabs. This is the tier for writers who want a dedicated writing environment and are allergic to subscriptions.
Plus at $10/month is the subscription tier that unlocks AI Fix, AI Sentence Structure, and the browser extension across Gmail, Docs, LinkedIn, and other web fields. Credit-metered on the AI features — typical usage lands in the "plenty for one writer" range, but heavy users can burn through credits on long documents. This is the tier for writers whose daily work benefits from an ambient readability layer plus on-demand rewrites.
Team at $15/user/month adds shared credit pools, admin billing, and a workspace view. Aimed at content teams, communications departments, and agencies where multiple writers need consistent readability standards.
The honest read: the free web app is enough for 80% of what Hemingway is famous for. Plus at $10/month is worth it if you want the browser extension across your daily writing (Gmail, Slack, LinkedIn) and use the AI Fix regularly. Most casual users can skip the subscription and stay on the free web tier indefinitely.
Pros
Cons
Marketing writers and copywriters. Landing page copy, email subject lines, headlines, product descriptions — anywhere clarity and directness matter more than voice. Hemingway is the fastest tool for the "is this actually punchy" check.
Business writing and internal communications. Memos, all-hands emails, strategy documents, shareholder letters. The kind of writing that will be read on a phone by a busy audience. Hemingway makes the "will they get through this" question answerable.
Bloggers and Substack writers before publishing. A final readability pass on a draft catches the sentences that will lose the reader. Not a substitute for editing, but a useful last-mile check.
ESL writers and non-native English writers. For anyone whose second language is English, the readability highlights are a genuinely useful signal about which sentences are getting complicated. Combined with AI Fix, this is a real learning loop.
Editors doing a first pass on client work. Freelance editors and content managers use Hemingway as a quick triage tool — highlight the red and yellow sentences first, then work through them. It is not the whole edit, but it is the first two hours of the edit.
Students writing essays. For undergraduate writing where clarity is being taught, Hemingway is a fair mechanical helper. Not for creative writing, where the readability rules actively fight your voice.
Landing page and product marketing teams. Team tier for the group that ships copy across a website. Consistent readability standards across a marketing team are legitimately valuable.
Bad fit. Fiction, poetry, and stylized long-form writing — Hemingway's rules fight literary prose. Academic papers with domain vocabulary — Grade 14+ is often the correct target for a peer-reviewed audience. Deep grammatical editing — Grammarly is the better tool for mechanics.
Hemingway's competitive landscape spans mechanical editors, AI writing tools, and readability-focused competitors.
Grammarly — the mechanical-editing competitor. Grammarly does grammar, spelling, punctuation, tone, and clarity across thousands of rules. Hemingway does readability and directness across a handful of rules. Completely different jobs. Serious writers often run both — Grammarly for the mechanics, Hemingway for the readability pass.
ProWritingAid — the more comprehensive competitor. ProWritingAid combines grammar, style, readability, pacing, and structure into one tool. More feature-rich than Hemingway, more complicated to use. If you want an all-in-one editor, ProWritingAid is the pick. If you want a fast readability check, Hemingway is faster.
Notion AI — different category, but relevant because Notion AI's "simplify" and "make shorter" commands overlap with Hemingway's AI Fix. If you already work in Notion, the built-in AI covers some of Hemingway's ground.
ChatGPT and Claude — the frontier-model alternative. Both can do readability rewrites with a good prompt. What they cannot do is give you the visual diagnostic — the color-coded highlights that make readability problems legible at a glance. Hemingway's UI is the differentiator, not the AI.
Readable.com — a direct readability-metric competitor. Focused on readability scoring (Flesch-Kincaid, Gunning Fog, SMOG) more than sentence-level highlights. Better for audits of existing content at scale; worse for drafting.
The Writer's Diet — a niche academic readability tool, free and browser-based. Similar spirit to Hemingway, narrower in scope. Fine for a one-off check.
Google Docs' built-in "Word count" and Docs' AI (Gemini) — the free-adjacent alternative if you already work in Docs. Not as sharp on the specific readability diagnostic, but adequate for casual writing.
Paste a real draft into hemingwayapp.com. Not a demo — something you were going to publish. The value of Hemingway is in seeing your actual writing lit up in colors.
Read the highlights before you change anything. Every yellow sentence is a warning; every red is a rewrite candidate. Every blue adverb is a "do you need this word." Every green passive-voice construction is a "who is doing the action." Learn to see them before you fix them.
Check the grade level. Compare it to your actual audience. Grade 6-10 is normal for professional writing. Grade 14+ is normal for academic writing. Grade 4 is normal for marketing copy targeting the general public. There is no "correct" score — only a correct match to your audience.
Try AI Fix on one red sentence. If you have Plus, use AI Fix on the worst-flagged sentence and judge whether the rewrite improves the sentence without stripping the voice. This is the tell for whether you should keep the subscription.
Install the Chrome extension if you are on Plus. The extension is the reason to be on Plus. Hemingway everywhere you write — Gmail, LinkedIn, Docs, Slack — is a meaningfully different experience from paste-and-check.
Do not treat Hemingway as gospel. The rules are useful defaults, not absolutes. If a long sentence works, keep it. If a passive voice is the right register, keep it. Hemingway is a diagnostic, not a jury.
Is Hemingway Editor free? The web app is free forever with full readability features. The desktop app is a $19.99 one-time purchase. Plus subscription at $10/month adds AI Fix and the browser extension. Team at $15/user/month adds admin features.
Does Hemingway Editor use AI? For readability highlights, no — it uses a rule-based readability model that has been refined for over a decade. For AI Fix (added 2024+), yes — rewrites and simplifications are powered by frontier language models under Hemingway's own prompt engineering.
Is Hemingway better than Grammarly? Different jobs. Grammarly does grammar, spelling, punctuation, and thousands of style rules. Hemingway does readability and directness with visual highlights. Most serious writers use both — Grammarly for the mechanical layer, Hemingway for the readability pass. Not competitive, complementary.
Can Hemingway edit long documents? The web app handles anything up to about 20,000 words comfortably. Beyond that, the browser struggles with rendering. Use the desktop app for anything book-length.
Does the desktop app still get updates? Yes — the classic $19.99 desktop app is maintained, though most new features (AI Fix, browser extension) live in the subscription tier. If you want a lifetime one-time purchase, the desktop app is the honest answer to that request.
Does Hemingway train on my writing? For readability highlights, no — the model is rule-based, not learned from user data. For AI Fix, generations route through frontier models under Hemingway's terms; check the current privacy policy for the specific data practices.
Is Hemingway good for fiction? Not particularly. The readability rules are calibrated for functional prose — marketing, business, journalism. Fiction and stylized writing routinely violate the rules for good reason. Use Hemingway on fiction cautiously and be ready to ignore the highlights.
The free Hemingway Editor at hemingwayapp.com is a "why don't you just have this bookmarked already" tool for anyone whose writing will be read by other humans, and Plus at $10/month is worth it for anyone whose daily writing lives in Gmail, LinkedIn, and Docs. The readability model has been quietly making writing clearer for over a decade, and the addition of AI Fix in 2024 closed the last real gap in the product. Combined with the browser extension on Plus, Hemingway becomes an ambient readability layer across every text field you type in.
Where Hemingway stops being the right answer: grammar and spelling (Grammarly is the specialist), stylized creative writing (the rules fight fiction), academic writing where domain vocabulary is the point (Grade 14+ is the correct target, not a problem), and team editorial workflows (Google Docs still wins). Hemingway is a solo writer's readability tool, and it is honest about that.
The honest recommendation: bookmark hemingwayapp.com today, run one real draft through it, and see if the highlights change how you think about your own sentences. If yes — and for most working writers, they do — decide whether the free web tier covers your workflow or whether the browser extension on Plus justifies $10/month. Most writers stay on free for years before eventually upgrading; a few upgrade immediately once they realize the extension puts Hemingway's readability engine into every email they write. Either path is honest. Just do not publish another long-form piece without pasting it into Hemingway once — the yellow and red highlights will teach you more about your prose in five minutes than any writing book has in a chapter.
