WriteWise – grammar fixer & AI prompt helper

Free, private spelling and grammar fixes in any text box, auto-fix as you type on AI chat sites, and one-click structured prompts.

WriteWise checks whatever you type, wherever you type it: email, forms, social posts, and the message box of AI assistants such as Claude, ChatGPT and Gemini. • A small badge appears on the text box you are using. Click it to see every spelling, grammar, punctuation, clarity and tone suggestion with one-click fixes. • On AI chat sites, safe fixes (typos, missing apostrophes, doubled words, their/there mix-ups) are applied automatically as you type, so the assistant always gets clean text. Turn this on for any site in the popup. • "Make it a prompt" turns rough notes into a structured prompt with Role, Task, Context, Requirements, Output format and Success criteria sections, with [brackets] for anything you still need to decide. • The popup lets you paste any text, fix it, and copy the result. Privacy: everything runs inside your browser. The extension makes no network requests, collects no data, and has no account. It is free and open source (MIT).
