privateSLM — private AI that runs on your device. Free. Chat with an AI that never sends a word to the cloud. privateSLM runs language models directly on your iPhone, iPad and Mac — no account, no server, no internet needed. On devices with Apple Intelligence it answers on the first tap, with nothing to download. On any other device, pick a free model and you are chatting in a minute. ASK YOUR DOCUMENTS — OFFLINE Attach a PDF, a Word file or a photo of a page and ask about it: • "Summarize this contract" • "What is the notice period?" • "Explain this letter in simple terms" The file is read on your device — scanned pages too, with on-device text recognition — and is never uploaded. Long documents work as well: privateSLM finds the passages that answer your question, or reads the whole document part by part for a summary. FREE, WITH NO CATCH • Chat with Apple Intelligence or free general models (Llama, Qwen, Gemma, Phi) • Documents: PDF, Word, text files and scans • Voice in and voice out • Chat history, Siri and Shortcuts, a Home Screen widget • No ads. No account. No tracking. EXPERT MODEL PACKS — PAY ONCE Want a specialist? Add a pack with a one-time purchase. No subscription, ever. • Tech Pack — coding, SQL, math and security models • Business Pack — law, finance and translation models • Health Pack — medical and mental-health models • All Packs — everything above, and every pack added later Purchases work with Family Sharing. Bought privateSLM when it was a paid app? Every pack is already yours, automatically. 100% PRIVATE Everything runs on-device. No sign-up, no analytics, no ads. Your chats and documents are stored only on your device. It works in airplane mode. BUILT TO ACTUALLY USE • Matched to your device — privateSLM checks your device's memory, on-device, and shows the models that will run well. • Resumable downloads that survive a dropped connection. • Speak your question, hear the answer. • Stop, copy or regenerate any reply. • Translate the chat into your language, on-device (iOS 18 and later). • Tune the system prompt and sampling. • Siri and Shortcuts: Ask, Summarize, Rephrase, Translate. PERFECT FOR • Contracts, letters and reports you would rather not upload anywhere • Flights and travel with no connection • When another AI's credits have run out • Anyone who wants answers that never leave the device Runs on-device with llama.cpp and Apple Intelligence. Note: Apple Intelligence requires a supported device and iOS 26 or later; on other devices the first answer needs a model download. 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 devices with 8 GB or more of memory.
