privateSLM: Local AI Chat

privateSLM — Private AI That Works Offline. No Subscription. Stop renting AI. privateSLM runs powerful open-source AI models 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”. Cheaper than a single month of most AI apps. • Works offline — on a plane, on the subway, travelling abroad with no data. 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. • 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, TOO On supported devices, privateSLM can use Apple's built-in system model — nothing to download, running on the Neural Engine. 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.
