Write with AI, right inside your pages
Gmail, Outlook, forms, LinkedIn, your CMS… Weightless AI fixes and rewrites your text right where you type it, and writes its answers at your cursor. No more copy and paste.
Most AI assistants live in their own window. To use them, you go back and forth: copy your text, paste it into the chat, then copy the answer back to where you needed it. Weightless AI takes the opposite route: the AI comes to your text.
Rewrite what you typed
In any field where you can type, select your text, or just click in it to take all of it. Right-click, then Weightless AI: rewrite, and five actions are waiting:
- Fix spelling & grammar, without touching the style;
- Rephrase: the same idea, more clearly;
- Shorten: the essentials, nothing more;
- More professional tone;
- Warmer tone.
The answer shows in the assistant, then automatically replaces the text in the page. It keeps its original language: an email in French stays in French, even if the extension is in English. And if you don’t like the result, the Undo button (or Ctrl + Z in the page) brings back the original.
Insert an answer from the assistant
Second case: you want a whole text written. Click in the field you want, open the assistant with Alt + W and ask for what you need. Under its answer, the Insert button writes it exactly at your cursor, with no stray formatting: no Markdown asterisks or hash signs in your email.
Where does it work?
Anywhere you type in a web page: Gmail, Outlook, contact forms, LinkedIn, X, Facebook, comment boxes, WordPress and most publishing tools.
Two limits, to be complete:
- Google Docs does not let an extension write into its documents. Weightless AI then copies the result and invites you to paste it with Ctrl + V.
- If the AI’s answer doesn’t look like rewritten text (a question, a comment), nothing is replaced: your text stays intact and the answer only shows in the assistant.
What about your data?
The extension has no permanent script on the sites you visit. It only reads or writes in a page when you ask it to, and only in the field you chose. The text goes only to the AI engine you picked, or stays on your computer with a local AI such as Gemini Nano.
