## Description

<a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/deab018b00684d495c627f558cc588eff4120880357254d700ea9e7631c38e4f/http%3A//WriteMate.io" rel="nofollow">WriteMate.io</a> 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 <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/deab018b00684d495c627f558cc588eff4120880357254d700ea9e7631c38e4f/http%3A//WriteMate.io" rel="nofollow">WriteMate.io</a>'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
<ul><li>Rewrite in the tone you want: Professional, Friendly, Casual, Formal, Concise, Empathetic, or Confident.</li><li>Fix grammar, spelling, and punctuation with a single click — no config, no red squiggles.</li><li>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.</li><li>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.</li><li>Refine any result — make it shorter, longer, or tweak it with a custom instruction — without starting over.</li><li>Read aloud any selection from the floating toolbar, or any result directly in the results panel — with play and stop controls.</li></ul>
Designed for how you actually write
<ul><li>Floating toolbar appears next to any selection on the page.</li><li>Editable-field trigger shows a small <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/deab018b00684d495c627f558cc588eff4120880357254d700ea9e7631c38e4f/http%3A//WriteMate.io" rel="nofollow">WriteMate.io</a> icon in focused inputs, textareas, and contenteditable fields, so the assistant is one click away without breaking your flow.</li><li>Results in a shadow-DOM panel that can't collide with a site's styles — one-click Copy and paste wherever you like.</li><li>Per-site disable — switch <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/deab018b00684d495c627f558cc588eff4120880357254d700ea9e7631c38e4f/http%3A//WriteMate.io" rel="nofollow">WriteMate.io</a> off on sites where you don't want it, from the popup.</li></ul>
History and templates
<ul><li>Review your recent generations, filtered by action — Rewrite, Fix Grammar, Generate, Translate, Refine, or Read Aloud.</li><li>Turn history off entirely in Settings if you prefer zero retention. History is encrypted on our server.</li></ul>
Three tiers — start free, upgrade for less than you'd expect
<ul><li>Anonymous (no signup): daily and monthly free quota. Great for trying everything.</li><li>Free (email or Google sign-in): a bigger quota, longer inputs and outputs, and more templates.</li><li>Pro: unlimited monthly usage, the longest inputs and outputs, every template — at the lowest price of any major AI writing extension.</li></ul>
Sign in with email and password or Google one-click sign-in.

Privacy and safety by default
<ul><li>Family-safe content filter is on by default. Unsafe prompts are sanitized, refused, or hard-blocked server-side and never charged against your quota.</li><li>You choose how much context <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/deab018b00684d495c627f558cc588eff4120880357254d700ea9e7631c38e4f/http%3A//WriteMate.io" rel="nofollow">WriteMate.io</a> can see — from nothing at all, to the site's name, to the surrounding field, to the full page — configurable in Settings.</li><li>Nothing we don't need. We don't log raw prompts, AI output, or page content. History is encrypted at rest.</li><li>No tracking pixels, no ad SDKs, no third-party analytics in the extension.</li></ul>
