A private AI assistant that runs entirely on your phone — powered by ternary. Ask it anything offline, in airplane mode. A working taste of the ternary future.
Store links are placeholders while we finish review. Android first; iPhone follows.
Ordinary AI does its sums in fine-grained numbers — expensive to store, expensive to move, expensive in energy. Ternary models think in just three states: +1, 0, −1. That makes the model small enough, and cheap enough, to run offline on a phone — no data centre, no bill, no waiting on a network.
A whole assistant in under a gigabyte. It loads into a phone's memory and answers there — nothing to upload, nothing to download per question.
Three-state maths moves and stores far less data per answer. That efficiency is exactly what lets a battery-powered device do the thinking.
The model is on the device. Turn off Wi-Fi and mobile data and it still answers — on a train, on a plane, off-grid.
A tiny model doesn't know everything — so we don't ask it to. T3ni's trick is augmentation over size: efficient routing and retrieval put curated facts and live tools in front of the model exactly when a question needs them. On real questions, that lifts a 1-billion-parameter model to the quality of something many times larger.
Exact arithmetic is computed, not guessed. Questions about your private data, your history, or the future are declined rather than invented. Every grounded answer is cited.
A fast compact model handles most things; harder questions escalate to a larger one automatically. You always see which model — and which experts — produced the answer.
Every reply can reach out to the web for a cited summary — but only when you tap it. Offline is the default; online is opt-in, and only your query ever leaves.
T3ni is private by construction, not by promise. There's no account to create, no profile to build, and no server that sees your conversations, your notes, or your files. In airplane mode it works exactly the same.
Everything runs on the device. A single toggle turns web lookups on, with a clear prompt — and only the query leaves, never your chat or your data.
Download and run. No sign-up, no ads, no analytics profile. What's on your phone stays on your phone.
Your session, notes and settings are stored encrypted on the device. You can wipe them any time.
Knowledge lives in small, curated expert packs — one per subject. The app carries a light footprint and you add the packs you care about; each is a few kilobytes and installs in a tap. New packs appear over time, with no app update needed.
Turn on the larger model and several experts can share one question — the model weaves their facts into a single answer and shows you which packs it drew on. A whole panel, deliberating on your device.
A routine gathers from the tools you've connected — calendar, weather, news, prices, your notes — and hands the model only the real data to summarise. No invented meetings, no made-up headlines: if it isn't there, it isn't in the briefing. One tap, a useful answer.
Today's calendar, weather and headlines, in a few lines — before you're out the door.
Tomorrow's schedule and any loose ends from your inbox, tied off for the night.
Point it at a receipt; it reads the text on-device and gives you clean rows.
Top headlines from your chosen feed, condensed to the bullets that matter.
Your watchlist prices with a one-line read — no dashboards to open.
A genuine nugget pulled from one of your experts, explained simply.
T3ni runs today on the ordinary binary chips already in your pocket — and it's genuinely useful. But those chips weren't built for three-state maths. On a true ternary chip — the silicon T3ISC is building — the same phone could hold and run a 35-billion-parameter model: a superagent, in your hand, offline, on a battery.
Here's the trick ternary unlocks. A 35B model normally needs ~70 GB and a data centre; in three states it shrinks to about 7 GB — small enough for a phone's memory. And because it's a mixture-of-experts, it thinks like a 35B model while only computing a few billion parameters per answer — so it stays fast and frugal enough for a battery. With a new wave of 35B-class models landing, picture that intelligence running privately in your hand. T3ni is the free, working preview — the chip is where it goes next.
