emoji-jev

Emoji autocomplete that asks Jev eight parallel questions per typing pause: emoji choice, emotion, mood, urgency, sarcasm and more.

Overview

Emoji Jev is emoji autocomplete at typing speed. As you type, a keyboard of up to 254 emojis lights up; each pause is one Jev call answering eight typed questions in parallel in about 100 ms of model time. They are a Choice over 64, 128 or 254 emojis with a probability for every key, a Choice over eight primary emotions shown as a distribution, three Scores for mood, urgency and energy, and three Booleans for sarcasm, joke and whether the writer wants a reply.

The README estimates about $0.0002 per keystroke because Jev bills input tokens only. It is built with TanStack Start on Cloudflare Workers, hosted by Whop, using the AI SDK's experimental evaluate function with the TypeSafe provider; it calls TypeSafe directly when a TypeSafe key is set and otherwise uses Vercel AI Gateway.
