privateSLM: Offline AI Chat

privateSLM — Answers Instantly. Nothing to Download.

Most on-device AI apps make you download a 2 GB model before your first answer.
privateSLM answers on the first tap: on devices with Apple Intelligence it uses
Apple's built-in system model, so there is nothing to download at all. Want a
specialist? Add an expert model whenever you like.

(On devices without Apple Intelligence, privateSLM downloads a model like any other
on-device app — pick a small one and you are chatting in a minute.)

And it runs entirely on your iPhone, iPad and Mac — no account, no cloud, no monthly
bill. Pay once, use it forever, and share it with your whole family.

WHY PRIVATESLM

• No subscription. One small payment, yours forever. No credits that "run out",
no bill that renews. Cheaper than a single month of most AI apps.
• Works offline. On a plane, on the subway, travelling abroad with no data —
the AI still answers. Airplane mode is no problem.
• 100% private. Everything runs on-device. No sign-up, no analytics, no ads, no
tracking. Your chats are stored only on your phone.
• Family Sharing. One purchase covers up to six people across iPhone, iPad & Mac.

AN EXPERT FOR EVERY JOB

Download a small specialist model and run it locally:
• Coding & SQL — Qwen2.5 Coder, IBM Granite
• Math & STEM — Qwen2.5 Math, NuminaMath
• Medical — BioMistral, Meditron (research-tuned)
• Legal — SaulLM, Law Chat
• Finance — finance-tuned assistants
• Translation — TowerInstruct
• Mental-health & soft skills — MentaLLaMA
• Plus fast general chat models for everyday questions

BUILT TO ACTUALLY USE

• Matched to your iPhone — privateSLM checks your device's memory on-device and
recommends models that will run well, so you don't download something too big.
• Full chat history — multiple conversations you can rename and 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.
• Tune the system prompt and sampling (temperature, top-p, and more).
• Built-in model manager with resumable downloads.

RUNS ON APPLE INTELLIGENCE

On supported devices, privateSLM uses Apple's built-in system model — zero bytes to
download, running on the Neural Engine. That is the fastest first answer we can give
you, and it costs no storage at all.

PERFECT FOR

• Flights and travel with no connection
• When your other AI's credits have run out
• Anyone who wants private answers that never leave the phone
• Families who don't want five separate AI subscriptions

Runs on-device with llama.cpp. Your conversations stay on your phone — always.

Note: the Medical, Legal and Finance models are AI assistants for general
information only — not professional medical, legal or financial advice. Larger 7B
expert models run best on recent iPhones with 8 GB+ of memory.
