Typeahead lives in the Windows system tray and finishes your sentences as you type — in WhatsApp, Chrome, Word, Outlook, and other Windows apps. Just press Tab to accept. Runs on a local AI model, fully offline and private, nothing you type ever leaves your PC.
You already know how the sentence ends before your fingers catch up. Phone keyboards guess the next word. Windows desktop apps mostly don't — you retype the same phrases, the same sign-offs, the same explanations, one keystroke at a time.
Typeahead watches the caret, not your clipboard. It runs a compact language model directly on your PC and quietly suggests how your sentence might continue — you keep typing, or press Tab and move on.
No gimmicks, no auto-generated paragraphs — just the next few words, offered when useful.
Messengers, browsers, mail, office, and editors — the suggestion appears next to the caret wherever you're typing, not in a separate window.
One keypress inserts the full suggestion. Keep typing and it's ignored — Typeahead never inserts anything without your say-so.
Suggestions come from Qwen 3 running through llama.cpp on your machine. No account, no telemetry on what you write, no network requirement to work.
Fast (~400 MB, default), balanced (~1.1 GB), or maximum quality (~2.5 GB) — choose the trade-off between speed and suggestion quality that fits your PC.
Custom autocorrect snippets and word-level dictionary completion work immediately — even before you've downloaded a model.
Change the accept key, turn Typeahead off per app, and rest easy — password managers and finance apps are protected by default.

Between Slack, Teams, and email, the same fifteen phrases carry most of the day. Typeahead offers them back before the second word is finished.
The multilingual model suggests in whatever language you're actively typing, so switching between English and your native language doesn't slow you down.
On a train, on a flight, or just with Wi-Fi off — suggestions in Notepad or a notes app keep working exactly the same, because nothing needs a connection.
Answering the same kind of question for the twentieth time today, Typeahead recognizes the pattern and offers to finish the sentence for you.
