Kill Grammarly
$12-$25/mo per user
Grammarly charges per user per month for grammar and writing suggestions. Claude does everything Grammarly does and significantly more - rewriting, tone adjustment, translation, summarization - for the cost of one subscription shared across your whole workflow. If you want inline browser suggestions like Grammarly, you can build a simple writing tool with Claude Code and deploy it for free.
Why Replace Grammarly?
- ×Per-user pricing adds up fast - a 5-person team pays $125/mo for glorified spell check
- ×Grammarly's cancellation flow is deliberately confusing with multiple retention screens and hidden cancel buttons
- ×AI writing assistants like Claude don't just fix grammar - they rewrite, adjust tone, translate, summarize, and generate from scratch
- ×Grammarly collects and processes everything you type through their servers - Claude API lets you keep data local
What People Use Grammarly For
Replacement Stack
Claude.ai Pro
The simplest replacement. $20/mo gets you unlimited grammar fixes, rewriting, tone adjustment, translation, and everything else Grammarly does - plus everything it can't. Paste text in, get it back polished. Works for your whole team if you share a workspace.
Anthropic API
For building custom tools. If you want an inline writing assistant (like Grammarly's browser overlay), you'll call the API from your own app. Haiku model handles grammar checks for fractions of a cent per request.
Vercel
Free hosting for your custom writing tool. Deploy the app Claude Code builds for you - no server management, automatic HTTPS, and it scales to zero when nobody's using it.
Kill Checklist
Export your Grammarly data
~10 minsLog into Grammarly > click your profile icon > Account > scroll to Data section > Request data export. They'll email you a ZIP with your saved snippets, style preferences, and personal dictionary. Save this - you'll use it to set up your Claude system prompt. If you use Grammarly's snippet feature, copy those out manually too since the export sometimes misses them.
Set up Claude.ai Pro
~10 minsGo to claude.ai and sign up for Pro ($20/mo). Create a new Project called 'Writing Assistant' and add a custom instruction like: 'You are my writing editor. Fix grammar, spelling, and punctuation. Improve clarity and conciseness. Match my existing tone. Return only the corrected text unless I ask for explanations.' This replaces Grammarly for all paste-and-fix workflows.

~15 minsIf you want inline suggestions like Grammarly's browser overlay, use Claude Code to build one. Open a terminal, run 'claude', and paste the prompt from the section below. Claude Code will scaffold a Next.js app with a text input, writing improvement buttons (Fix Grammar, Improve Clarity, Make Concise, Change Tone), and Anthropic API integration. The whole build takes about 5 minutes.
