Grammarly vs ProWritingAid vs Hemingway (2026)
Grammarly renamed Business to Pro and raised the team plan to $15/seat. ProWritingAid monthly is $30 — the $10 figure many sites quote is the annual rate. Hemingway dropped its $20 desktop app as the main product; Editor Plus starts at $10/month. Multiple pricing corrections inside.
Three pricing errors fixed: Grammarly Business is now called Pro ($15/seat/mo annual) — same price, new name, added team features. ProWritingAid monthly is $30/mo (not $10 — $10 is the annual rate). ProWritingAid now has two paid tiers: Premium and Premium Pro. Hemingway Plus annual is $100/yr ($8.33/mo) not $10/mo. All verified May 2026.

The Full Picture
Grammarly — The Writing Assistant That Goes Everywhere
Grammarly’s core advantage is ubiquity. It works in Gmail, Google Docs, Microsoft Word, Slack, LinkedIn, and virtually every text field in your browser without any copy-paste workflow. Suggestions appear inline as you type, making corrections feel natural rather than requiring a separate editing pass. For professionals writing across multiple platforms throughout the day, this integration depth is genuinely valuable and practically impossible for competitors to match.
In 2026, Grammarly restructured its plans. Grammarly Business was renamed Grammarly Pro — same $15/member/month annual price, but with expanded features: 2,000 monthly AI prompts (double Premium’s 1,000), team style guides, brand tones, knowledge share, snippets, and usage analytics. Grammarly Premium ($12/mo annual) remains the individual plan and is being gradually migrated to Pro for users who purchased via Grammarly’s website. App Store and Google Play subscribers keep Premium as-is. The free plan’s 100 AI prompts per month is the most accessible AI writing assistance available at zero cost, with no word limit — a meaningful advantage over ProWritingAid’s 500-word free cap.
The privacy caveat matters for certain users. Grammarly’s free tier terms allow use of writing data for AI model improvement. For users handling unpublished manuscripts, confidential legal or business content, or proprietary research, this is worth understanding before using the free plan with sensitive material. Paid tiers have improved privacy controls. For general professional writing — emails, reports, presentations, Slack — Grammarly remains the most capable all-around tool, and the free plan’s grammar checking is genuinely strong.
ProWritingAid — The Developmental Editor in Software Form
ProWritingAid operates on a different philosophy from Grammarly. Rather than providing suggestions as you type, it analyses completed writing and generates detailed reports across 25+ dimensions: readability, pacing, overused words, sentence length variation, dialogue tags, sticky sentences, clichés, author comparisons, and more. This report-based approach is slower than Grammarly’s inline model, but it provides structural and stylistic analysis that helps writers understand patterns, not just fix individual errors. For novelists, ProWritingAid is in a fundamentally different category. Its Scrivener integration means authors work directly in their manuscript tool. 40+ genre presets calibrate the analysis to each writing type.
The pricing trap that catches many buyers: ProWritingAid’s $10/month figure that appears across comparison articles is the annual billing rate. Monthly billing is $30/month — three times more. On a month-to-month basis, ProWritingAid Premium is the most expensive individual option in this comparison. The annual plan at $120/year is the best per-feature annual value here. The lifetime plan at $399 (Premium) breaks even against the annual plan after 3.3 years — a compelling option for serious writers planning to use the tool long-term. Premium Pro at $12/month annual ($144/yr) or $699 lifetime adds 50 AI Sparks per day (vs 5 on Premium) and enhanced AI capabilities.
Privacy is a genuine differentiator. ProWritingAid explicitly does not use your writing to train its AI models — a meaningful assurance for authors with unpublished manuscripts, journalists with sensitive sources, or businesses handling proprietary content. The free plan allows 500 words per check and 2 report runs per day — enough to evaluate the tool but not for regular production use. Commit to the annual or lifetime plan from the start if ProWritingAid is your choice.
Hemingway Editor — Clarity Above All
Hemingway Editor is the most focused tool in this comparison. It does one thing — readability analysis — with more immediacy than either Grammarly or ProWritingAid. Paste text into the free web editor and it instantly highlights long sentences in yellow and red by severity, passive voice in green, adverbs in blue, and complex words in purple. A grade-level readability score using Flesch-Kincaid appears at the side. The visual immediacy makes problems obvious in a way that text-based suggestions don’t — you can see at a glance whether your writing is dense or accessible. The free web app has no account requirement and no word limit, making it the most accessible free writing tool in this comparison for readability work.
Hemingway has restructured its product in 2026 around Editor Plus, the subscription plan with AI grammar checking and sentence rewrites. Individual plans: Plus 5K at $10/month monthly ($8.33/month annual, $100/year) with 5,000 AI sentence credits, and Plus 10K at $15/month monthly ($12.50/month annual, $150/year) with 10,000 credits. Grammar checking is unlimited on Plus plans (not counted against the AI sentence credit allotment). A 14-day free trial is available with up to 200 sentence corrections and no credit card required. The $19.99 desktop app remains available for offline readability editing, but it does not include AI features.
Hemingway’s limitation is its focus. The free version has no grammar checking. The Plus subscription competes directly with Grammarly Premium at a similar price point ($10/mo vs $12/mo), but Grammarly’s grammar checking is more comprehensive and its browser integration eliminates the copy-paste workflow that Hemingway requires. The optimal use case for Hemingway is a final readability pass before publishing — either standalone for bloggers, or in combination with Grammarly for professionals who also need grammar coverage.
