privateSLM: Local AI Chat

privateSLM is a fully private AI chat that runs entirely on your device. No account. No cloud. No data ever leaves your phone.

Unlike cloud chatbots, privateSLM keeps every conversation 100% on-device — and unlike other local AI apps, it automatically uses the fastest engine your phone already has.

SMART ENGINE — ZERO SETUP
• On Apple Intelligence devices, privateSLM uses Apple's built-in system model. Nothing to download. Instant. Runs on the Neural Engine.
• On other devices, download a small, fast open model (Llama, Qwen, Gemma) once and run it locally — no servers involved.

EVERYTHING STAYS PRIVATE
• 100% offline. Airplane mode works fine.
• No sign-up, no analytics, no ads, no tracking.
• Your chats are stored only on your device.

BUILT FOR REAL USE
• Full chat history with multiple conversations — search, rename, delete.
• Voice in and voice out: speak your question, hear the answer hands-free.
• Edit a message and regenerate. Stop, copy, or re-run any reply.
• Customise the system prompt and sampling (temperature, top-p, and more).
• Pick and manage your own models with a built-in download manager.

WORKS EVERYWHERE
• iPhone, iPad and Mac — with a layout that adapts to big screens.

ONE-TIME PURCHASE
• Buy once. No subscription. No hidden costs.

privateSLM — private AI, on your device.
