Stop Retyping the Same Text — Save Hours Every Week
Stop losing time to retyping the same text—save hours every week with the AI-powered text expander for Windows, Mac & Linux. Type an abbreviation, expand it into full emails, code, or templates — then enhance with AI or dictate by voice, all in any app.

Same expansion everywhere — pick where you type:
Below, each app has its own mini steps (type → trigger → filled).
Try it yourself: type the abbreviation “email” in To (the word alone). Press F1 or Ctrl+Enter — To fills first, then Subject, then the message. Or tap “Simulate full flow”.
Type “email” in To.
Works the same in Outlook, Slack, VS Code, terminal, and anywhere you type.
Word-style documents — a short token becomes a full paragraph.
Type brief in the page, then F1 or Ctrl+Enter — or use Simulate full flow.
Type “brief” in the document.
Works in Word, Google Docs, Pages, and other rich-text apps.
Chat — reply to someone in WhatsApp, Messenger, or Slack with a snippet.
Someone wrote you below — type brb in the reply box, then F1 or Ctrl+Enter. Or simulate.
Type “brb” as your reply.
Same flow in WhatsApp, Facebook Messenger, Slack, Teams chat, and more.
Editor or terminal — abbreviations become real code.
Type api, trigger, and a full async fetch helper (try/catch, JSON, console.table) appears — with VS Code–style colors. Or simulate.
Type “api” (demo abbreviation).
Works in VS Code, Cursor, JetBrains IDEs, terminal, and every editor.
