Writingmate

Writingmate started as a ChatGPT-powered writing helper for email and messages, and has since grown into an all-in-one AI sidebar. The extension sits in the Chrome toolbar and opens with a click or the Cmd/Ctrl+M shortcut, giving you a chat interface without switching to a separate tab. Because it can read the page you are on, you can ask it to summarise an article, explain a paragraph, or turn what you are reading into a draft.

What sets it apart is model choice. Writingmate routes your request to GPT, Claude, Gemini or Grok, so you can pick whichever model suits the task — a long document, a coding question, a creative rewrite — or compare outputs. Alongside chat, it handles writing tasks like drafting and replying to email in Gmail, generating blog posts and marketing copy, fixing grammar, translating and summarising. Image generation is included as well.

The team behind it says it was built by people who previously worked at high-growth tech companies, and positions Writingmate as a lighter-weight alternative to tools like Wordtune and Jasper. The free tier is advertised as forever free, with a Premium upgrade for users who need more capacity.
