Top Recommended Replacements
Grammit
FREEBest Overall FOSS Alternative
Why we like it
Runs locally on your device for total privacy; uses an on-device Large Language Model (LLM) to check grammar and style; 100% free with no server-side data tracking.
Keep in mind
Requires more hardware power (RAM) since the AI runs locally on your computer.
LanguageTool
Best for Multilingual Writers
Why we like it
Excellent open-source core; supports 30+ languages; 'Picky Mode' catches advanced stylistic issues; works as a browser extension or standalone app.
Keep in mind
The most advanced style suggestions (comparable to PWA) are behind a premium subscription.
Slick Write
FREEBest for Stylistic Reports
Why we like it
Completely free; provides detailed reports on adverbs, passive voice, and 'prepositional starts' similar to ProWritingAid's 20+ reports.
Keep in mind
The interface is functional but feels dated; lacks AI-driven 'rewriting' features found in newer tools.
Hemingway Editor
FREEBest for Readability
Why we like it
Classic tool for stripping 'fluff' from writing; highlights hard-to-read sentences and weakens verbs; perfect for punchy, direct prose.
Keep in mind
Does not catch spelling or complex grammar errors; web version is free but the desktop app is a one-time purchase.
QuillBot (Free Tier)
FREEBest for Paraphrasing
Why we like it
Unmatched AI paraphraser; free version includes unlimited grammar checking; helps rephrase awkward sentences to improve flow.
Keep in mind
Free tier has word-count limits for the paraphraser; plagiarism checker is a paid feature.
Scribens
FREEBest for Detailed Explanations
Why we like it
Uses a sophisticated AI syntaxical recognition algorithm; provides detailed explanations for every error to help you learn; supports 30+ languages.
Keep in mind
The free plan has a character limit per check (approx. 8,000 characters).
Trinka AI (Free Tier)
FREEBest for Academic Writing
Why we like it
Specialized in technical, medical, and formal English; catches terminology errors that general tools miss; prioritizes data privacy.
Keep in mind
Limited monthly 'credits' for advanced checks in the free version.
Virtual Writing Tutor
FREEBest for ESL/Education
Why we like it
100% free; includes tools for checking topic sentences, essay structure, and even target vocabulary levels.
Keep in mind
The interface is very cluttered and geared toward students rather than professional novelists.
Wordtune (Free Tier)
FREEBest for Contextual Rewriting
Why we like it
Focuses on 'meaning' rather than just rules; helps you rewrite sentences to be more formal, casual, or concise.
Keep in mind
Free plan is limited to 10 rewrites per day.
PaperRater
FREEBest for Automated Scoring
Why we like it
Analyzes your writing and gives it a 'grade' based on vocabulary and style; includes a basic plagiarism check for free.
Keep in mind
Web-based only; interface is ad-heavy.
Sapling (Free Edition)
FREEBest for Customer Support Teams
Why we like it
Extremely fast; provides grammar checks in real-time across CRM and helpdesk tools; great for professional brevity.
Keep in mind
Advanced 'Style Guide' features are paid.
Grammarly (Free)
FREEBest for Basic Polish
Why we like it
The most polished interface; excellent real-time spelling and punctuation; high reliability across almost all web apps.
Keep in mind
The free version is much more restrictive than ProWritingAid, only offering basic grammar and spelling.
