privateSLM: Offline AI Chat

About this app

<p>privateSLM — Answers Instantly. Nothing to Download.</p>
<p>Most on-device AI apps make you download a 2 GB model before your first answer.<br />
privateSLM answers on the first tap: on devices with Apple Intelligence it uses<br />
Apple's built-in system model, so there is nothing to download at all. Want a<br />
specialist? Add an expert model whenever you like.</p>
<p>(On devices without Apple Intelligence, privateSLM downloads a model like any other<br />
on-device app — pick a small one and you are chatting in a minute.)</p>
<p>And it runs entirely on your iPhone, iPad and Mac — no account, no cloud, no monthly<br />
bill. Pay once, use it forever, and share it with your whole family.</p>
<p>WHY PRIVATESLM</p>
<p>• No subscription. One small payment, yours forever. No credits that "run out",<br />
no bill that renews. Cheaper than a single month of most AI apps.<br />
• Works offline. On a plane, on the subway, travelling abroad with no data —<br />
the AI still answers. Airplane mode is no problem.<br />
• 100% private. Everything runs on-device. No sign-up, no analytics, no ads, no<br />
tracking. Your chats are stored only on your phone.<br />
• Family Sharing. One purchase covers up to six people across iPhone, iPad & Mac.</p>
<p>AN EXPERT FOR EVERY JOB</p>

<p>BUILT TO ACTUALLY USE</p>
<p>• Matched to your iPhone — privateSLM checks your device's memory on-device and<br />
recommends models that will run well, so you don't download something too big.<br />
• Full chat history — multiple conversations you can rename and delete.<br />
• Voice in and voice out — speak your question, hear the answer hands-free.<br />
• Edit a message and regenerate. Stop, copy, or re-run any reply.<br />
• Tune the system prompt and sampling (temperature, top-p, and more).<br />
• Built-in model manager with resumable downloads.</p>
<p>RUNS ON APPLE INTELLIGENCE</p>
<p>On supported devices, privateSLM uses Apple's built-in system model — zero bytes to<br />
download, running on the Neural Engine. That is the fastest first answer we can give<br />
you, and it costs no storage at all.</p>
<p>PERFECT FOR</p>
<p>• Flights and travel with no connection<br />
• When your other AI's credits have run out<br />
• Anyone who wants private answers that never leave the phone<br />
• Families who don't want five separate AI subscriptions</p>
<p>Runs on-device with llama.cpp. Your conversations stay on your phone — always.</p>
<p>Note: the Medical, Legal and Finance models are AI assistants for general<br />
information only — not professional medical, legal or financial advice. Larger 7B<br />
expert models run best on recent iPhones with 8 GB+ of memory.</p>
