Most "AI" apps are a thin shell around a server somewhere. Everything you type goes there. This one doesn't work that way — put your phone in Airplane Mode and it still answers.
Once you're set up there's nothing left to connect to. Planes, trains, tunnels, remote places — or just a phone you'd rather didn't phone home.
Your conversations live on your phone as files you control. It works without an account, and your history stays entirely on the device.
Answers stream in as you'd expect from a good chat app, with all the work happening on your phone rather than over a connection.
Pick from a curated set of well-known open models — or browse a much larger library and install a different one whenever you like.
Point it at a PDF or a photo and ask about it. Private by default, because there's nowhere for the file to be sent.
Summarize, rewrite and pull details out of text from any Shortcut or automation, without any of it leaving your phone.
Private AI on a phone got good enough to be genuinely useful. The app is built around the things you'd actually want it for, rather than an empty chat box.
A curated set of well-known open models, ready to install in a couple of taps — plus a browser for thousands more from Hugging Face. You pick which one runs on your phone, and you can change your mind any time.
| Model | Made by | Best at |
|---|---|---|
| Gemma 4 & Gemma 2 | An all-round default — clear writing and dependable everyday answers | |
| Llama 3.2 | Meta | Summarising, rewriting and following instructions closely |
| Qwen 3 & Qwen 2.5 | Alibaba | Strong multilingual work, and the widest choice of sizes |
| Phi-4 Mini | Microsoft | Reasoning and structured answers for its size |
| DeepSeek R1 | DeepSeek | Working through a problem step by step |
| Ministral 3 | Mistral AI | Fast, direct answers with little padding |
| SmolLM 3 & SmolLM2 | Hugging Face | Quick everyday tasks on older iPhones |
| MiniCPM5 | OpenBMB | A capable lightweight option |
| Bonsai | Prism ML | Punching above its weight — more capability than the size suggests |
Bigger models write better answers and ask more of the phone; lighter ones are faster and kinder to the battery. The app marks which options suit your particular iPhone before you download anything — see will it run on my iPhone.
Install it, set it up once, and it just works from then on.
iPhone or iPad on iOS 17 or later. Anything from the last few years works well.
Follow the recommendation for your device — every option is marked for your specific iPhone, so you never end up with something that runs badly. Takes a couple of minutes, and you only do it once.
That's the whole test — and the whole point. It keeps working.
Really offline. Your conversations never touch a network — there's no service behind the app to send them to. The only thing that needs a connection is the initial setup and browsing for new options later.
Well-known open models including Gemma from Google, Llama from Meta, Qwen from Alibaba, Phi-4 Mini from Microsoft, DeepSeek R1, Ministral from Mistral AI, SmolLM from Hugging Face, MiniCPM5 from OpenBMB and Bonsai from Prism ML — plus thousands more available from Hugging Face through the in-app browser. You choose which one runs on your phone and can switch at any time.
Anything running iOS 17 or later works. Newer phones handle the more capable options, but the app adjusts what it recommends to whatever device you have.
Honestly, no — and anyone telling you otherwise is selling something. An AI that fits on a phone is very good at summarizing, rewriting, extracting and everyday questions. It's weaker at hard reasoning, and it doesn't know about current events. If you want frontier quality and you're happy sending your data to a server, use a cloud app. This is for the times you can't, or would rather not.
It's real work for your phone, so a long session uses meaningful battery and warms the device a little. Lighter options cost much less of both, and the app makes it easy to switch.
Full access free for three days. After that, one payment unlocks everything permanently — no subscription, no credits, no charge per message. Current pricing is shown on the App Store.
One independent developer, not a company with a data business. That's also why there's no account system: it would be more work and worse for you.
Free for three days. Then buy it once and keep it.
