Typeahead for Windows For Non-Native Speakers
For Writing in a Second Language

You know what you mean.
Typeahead helps you finish saying it.

The pause before finishing a sentence in a second language isn't about vocabulary — it's about grammar and phrasing landing right. Typeahead offers a likely, natural-sounding ending as you type, in the language you're actually using, so the sentence you started doesn't stall halfway through.

Confidence, not correction.

The Problem

Writing an email or a chat message in a language that isn't your first often means slowing down mid-sentence to figure out how a native speaker would phrase the rest.

  • Grammar checkers correct after the fact, but don't help you finish the sentence in the moment
  • Phone-style autocomplete only predicts single words, not full phrase structures
  • Switching mentally between two languages during a chat or email slows typing further
  • Most desktop apps offer no in-context help at all while typing

How Typeahead Helps

Typeahead's underlying model is multilingual and reads the language you're currently typing in, offering a natural continuation of the sentence instead of leaving you to work it out alone.

  • Suggests in whichever language you're actively typing — no manual language switch
  • Offers full phrase completions, not single next-word guesses
  • Works the same in email, chat apps, and browsers
  • Ignore any suggestion by simply continuing to type your own words
For everyday typing
Built for switching between languages

Whether you write mostly in English or move between two or three languages a day.

100+ languages, one model

The local model understands and suggests across a wide range of languages, so it keeps up whether you're typing in English, Spanish, Arabic, or a dozen others.

No manual language switch

Typeahead reads what you've typed so far and suggests in that language automatically — there's no setting to change when you switch languages mid-conversation.

Works across your apps

Email, chat, browsers, and Word — the same suggestions follow you between the apps you switch between during the day.

Private by design

Everything runs locally. Emails and messages you're still drafting in a second language never leave your PC.

FAQ
Common questions
Does it correct my grammar?
Not directly. Typeahead suggests how a sentence is likely to continue, based on general phrasing patterns from a local model. It doesn't flag or fix mistakes in text you've already written — it's a completion tool, not a grammar checker.
Do I need to set my language manually?
No. Typeahead suggests in whichever language you're actively typing, and it switches automatically if you move between languages within the same document or chat.
How many languages does it support?
The underlying model is multilingual and covers 100+ languages.
Does it work in email and chat apps?
Yes. It works in mail clients like Outlook and Thunderbird, messengers like WhatsApp, Telegram, and Slack, browsers, and Word.
Is what I type sent anywhere for translation or processing?
No. Suggestions are generated entirely on your PC by a local model. There's no account, no cloud translation service, and no telemetry on your text.
