WriteMate.io - AI Writing Assistant

WriteMate.io is the cheapest AI writing assistant for the browser. Rewrite in any tone, fix grammar, translate to your preferred language, read text aloud, and generate emails and posts — on almost any website.

Features & Capabilities

WriteMate.io is a fast, privacy-first AI writing assistant that works on almost any website. And it's the cheapest one you'll find — Pro costs a fraction of what other AI writers charge. Select any text on a page and WriteMate.io's floating toolbar lets you rewrite, fix grammar, translate, or read it aloud in one click. No account required to get started.

What you can do

  • Rewrite in the tone you want: Professional, Friendly, Casual, Formal, Concise, Empathetic, or Confident.
  • Fix grammar, spelling, and punctuation with a single click — no config, no red squiggles.
  • Translate to and from every major world language, including English, Spanish, French, German, Italian, Portuguese, Dutch, Swedish, Polish, Russian, Turkish, Arabic, Hindi, Indonesian, Japanese, Korean, and Chinese. Set a default target language once in Settings.
  • Generate emails, social posts, and more from built-in templates — professional and friendly emails, follow-ups, LinkedIn posts, short posts for X, apology messages, thank-you notes, meeting summaries, product descriptions, and blog post intros.
  • Refine any result — make it shorter, longer, or tweak it with a custom instruction — without starting over.
  • Read aloud any selection from the floating toolbar, or any result directly in the results panel — with play and stop controls.
Designed for how you actually write
  • Floating toolbar appears next to any selection on the page.
  • Editable-field trigger shows a small WriteMate.io icon in focused inputs, textareas, and contenteditable fields, so the assistant is one click away without breaking your flow.
  • Results in a shadow-DOM panel that can't collide with a site's styles — one-click Copy and paste wherever you like.
  • Per-site disable — switch WriteMate.io off on sites where you don't want it, from the popup.
History and templates
  • Review your recent generations, filtered by action — Rewrite, Fix Grammar, Generate, Translate, Refine, or Read Aloud.
  • Turn history off entirely in Settings if you prefer zero retention. History is encrypted on our server.
Three tiers — start free, upgrade for less than you'd expect
  • Anonymous (no signup): daily and monthly free quota. Great for trying everything.
  • Free (email or Google sign-in): a bigger quota, longer inputs and outputs, and more templates.
  • Pro: unlimited monthly usage, the longest inputs and outputs, every template — at the lowest price of any major AI writing extension.
Sign in with email and password or Google one-click sign-in.

Privacy and safety by default

  • Family-safe content filter is on by default. Unsafe prompts are sanitized, refused, or hard-blocked server-side and never charged against your quota.
  • You choose how much context WriteMate.io can see — from nothing at all, to the site's name, to the surrounding field, to the full page — configurable in Settings.
  • Nothing we don't need. We don't log raw prompts, AI output, or page content. History is encrypted at rest.
  • No tracking pixels, no ad SDKs, no third-party analytics in the extension.
Cross-browser

Works in Chrome, Edge, and Firefox, built on Manifest V3 with a standard cross-browser API layer.

Accessibility

Keyboard-accessible controls, ARIA labels throughout, and Read Aloud for any result — including right-to-left languages.

Install WriteMate.io, highlight any text on the web, and start writing better in seconds.
