Private AI that runs on your iPhone
The model is downloaded to your device and runs there. It works in Airplane Mode, and nothing you type is sent anywhere — because there is nowhere for it to be sent.
iPhone 11 or newer · iOS 17 or later
On your device
Inference runs on the phone's own chip. No server is involved at any point.
Works offline
Once a model is downloaded, the app never needs a connection again.
No account
No sign-up, no analytics, no tracking. There is nothing to log in to.
What it does
A full assistant, not a demo. Everything below happens locally.
Chat
Streaming replies, full history with search and pinning, and per-chat instructions. Ask it to summarise, rewrite, explain or draft.
Ask your documents
Add PDFs or paste notes. They are chunked and indexed on the device, and answers cite the passage and page they came from.
Ask a photo
Vision models describe images, read text out of them and pull out details — without the photo ever leaving your phone.
Memory
Facts it remembers about you, visible and editable, with a toggle on every single entry. Plus custom instructions for how it writes.
Model lab Advanced
Live memory and thermal readout, per-model speed benchmarks on your own device, and sampling controls.
Open model library Advanced
Browse MLX-ready models on Hugging Face and load your own. You pick, the app runs it.
Bring your own model
A curated catalogue of open models, each marked against what your specific iPhone can actually hold.
"Will it run" is measured, not guessed.
The number that decides whether a model works is not how much RAM your iPhone has — it is how much memory iOS will let this one app hold before it kills it. The app reads that figure from the system at runtime and rates every model against it, so you find out before you download two gigabytes, not after.
Pricing
Three days of everything, no payment details required. After that it keeps working — or you unlock the rest.
The free tier is real. When the trial ends, a small model stays available forever, and every conversation, document and note you already made stays exactly where it is. Nothing you wrote gets locked away.
You are paying for the features — document indexing, vision, memory, the model lab, the full catalogue — not for the models. Those are other people's open-source work.
