Keyda

Your Keyda notes, docs and AI sessions in the browser — plus one-click grammar fixes anywhere you type.

Keyda is an AI writing assistant for your browser. Fix grammar and spelling in any text field, rewrite or summarise anything you select, and reach your Keyda notes, documents and AI chats without leaving the page. WRITE BETTER, ANYWHERE Keyda underlines misspellings as you type in almost any text field on the web — Gmail, WhatsApp Web, forms, comment boxes. Click an underlined word and it is fixed instantly, offline, with no AI call and no waiting — free with any signed-in account. For a fuller rewrite, click the floating Keyda button beside the field. It returns a corrected version of the whole sentence, plus Rephrase and Tone options (Formal, Friendly, Professional, Casual, Confident). Drag the button anywhere on screen and it stays where you put it. Prefer it to work on its own? Turn on "Direct suggests" in Settings and Keyda checks as you type. SELECT ANY TEXT, ASK ANYTHING Select text anywhere on a page and a small toolbar appears: • Response — answers a question, drafts a reply to a message, or gives you a useful take on what you selected • Fix — grammar and spelling • Rephrase, and Tone • Summarize, Translate, Explain / Simplify, and Continue writing Replace the text in place where the page allows it, or copy the result. NOTES, DOCS AND AI IN A SIDE PANEL Sign in with Google or your phone number and open the Keyda side panel. Unlike a popup it stays open while you browse, so your notes and answers are still there when you click back into the page. Your Notes, Documents and AI Sessions from the Keyda app are all in it — search them, create them, delete them, and start new AI conversations. WORKS YOUR WAY • Alt+Shift+K fixes whatever field you are typing in • Right-click selected text for "Fix grammar with Keyda", "Rephrase with Keyda" or "Save selection to Keyda Notes" • Turn Keyda off on any individual site: open the Keyda popup on that site and switch "Keyda on this site" off • Light and dark themes • Turn off underlines, the floating button, or automatic checking in Settings at any time SITES YOU USE KEYDA ON (OPTIONAL, OFF BY DEFAULT) Turning Keyda off on a site works on its own, with no account, and nothing is sent anywhere. If you also turn on "Sync my site settings" in Settings, those per-site on/off switches follow you to every browser you sign in to, along with a list of the sites where you use Keyda. Keyda then stores only the site name — for example github.com — and how many times you used it there. It never stores the page address, what is on the page, or the sites you simply visit without using Keyda. You can switch any site back on, forget any single site, clear the whole list, or turn syncing off — and turning it off deletes the list from our servers. PRIVACY Fixing an underlined word runs entirely inside your browser against an offline dictionary; that text never leaves your device. Sentence rewrites, selection actions and your Notes, Documents and AI Sessions go through your signed-in Keyda account. Keyda reads the contents of a text field only when you ask it to — never passively, and never from password fields. Full privacy policy: https://keyda.in/privacy-policy.html Requires a free Keyda account (sign in with Google or phone number). Some AI features need an active Keyda plan.
