iPhone
Drystone runs open-source AI models entirely on your iPhone. No account. No tracking. No cloud. Like a dry stone wall, it is built without mortar, your conversations never touch a server, because there is no server.
A GUIDED START
A one-minute intro asks what you'll use it for everyday chat, research and science, coding, writing, translation, reasoning; then matches a model to your exact iPhone and downloads it. Open the app and it's ready. Replay the intro any time from Settings.
CHAT, FULLY OFFLINE
Download a model once over Wi-Fi, then chat anywhere: on a flight, on the fells, on the Tube, in a basement. Replies stream instantly from your phone's own chip, accelerated by Apple's GPU. Your last model loads automatically on every launch, and you can switch models mid-thought straight from the composer. Flip on Airplane Mode and everything still works. That is not a marketing claim; it is a ten-second test you can run today.
ASK YOUR DOCUMENTS
Tap + and drop a PDF, report, or notes file directly into the conversation. Drystone indexes it on-device and answers from it, citing the excerpts it used with the honesty to say when the answer is not in the document. Files belong to the chat you attach them to, and are removed with it. Contracts, research papers, funding guidelines: interrogate confidential material without it ever leaving your hand.
MODELS MATCHED TO YOUR PHONE
Drystone reads your iPhone's exact chip and memory, then recommends models that genuinely run well on it — from featherweight 1B models on older devices to 7B-class on Pro iPhones. Browse a curated catalog (Llama, Qwen, Mistral, Phi, Gemma, DeepSeek, and research and biomedical picks), search all of Hugging Face with optional token support for gated models, or import your own GGUF files. Multi-gigabyte downloads continue while your phone is locked and resume if interrupted. Unload a model from memory or delete it from storage with one tap.
PRIVATE BY ARCHITECTURE, NOT BY PROMISE
Chats encrypted at rest with AES-256; the key never leaves your device's Keychain
Face ID or passcode lock, plus incognito chats that never touch disk
A one-tap network kill switch, with a transparency log of every request the app makes
On-device dictation; your voice is processed by your phone, never uploaded
Choose an offline voice for spoken replies
Every destructive action asks first, and erasing really erases
AND THE USEFUL EXTRAS
Pin, rename, and organise chats; export any conversation as a clean PDF
A fresh chat on every launch, with history one tap away
Ask via Siri and Shortcuts; share text from Safari to summarise offline
Benchmark your phone's real AI speed with one tap
Edit and resend any message, or regenerate any reply
AN HONEST NOTE
Phone-sized models are not frontier cloud AI. They are genuinely good at drafting, summarising, translation, and answering from documents you attach; and they work where the cloud cannot follow: offline, and in confidence. Drystone tells you the truth about what fits your device and how fast it runs, because trust is the entire point.
WHO IT'S FOR
Travellers beyond signal. Professionals under confidentiality; legal, health, research, public sector. Students and the curious. Anyone whose questions, or documents, deserve to stay private.
No account. No subscription. No data collected; check the App Store privacy label: it says "Data Not Collected" because there is nothing to collect. Everything in this version is free and stays free, for everyone, permanently.
Drystone. Built without the cloud.
