Silo vs Chat LLM

Silo runs AI models like Gemma 4, Phi-4, and Mistral directly on your iPhone. No servers. No subscriptions. No internet connection. Your conversations never exist anywhere but your device. Actually Private, Not "Cloud Private" Most AI apps encrypt your data before sending it to their servers. Silo never sends it at all. Zero network requests. There is no server to breach. No account required. No login. No data collection. Anonymous by design. Works Without Internet Airplane mode, off-grid, no Wi-Fi. Silo works everywhere because everything runs on your hardware. No connection means no data leaks. Ever. Chat on a plane, in the subway, or anywhere you want absolute privacy. No Subscription. No Limits. No $20/month plans. No lifetime unlock fees. No usage limits. No accounts. No paywalls. Download and use every feature immediately. Open-Source Silo's complete source code is public on GitHub. Don't take our word for privacy.

Private AI chat that works offline. Free, no account needed. Plus 300+ cloud models, real-time Grok and Gemini voice, and your computer's models via LM Studio. On-device AI for private offline chat The on-device Llama model is an optional one-tap download from the model picker. The app installs under 10 MB without it. Free cloud chat, no account needed Cloud LLM is powered by Groq and works out of the box. No signup, no key required. 300+ models via OpenRouter Connect your OpenRouter key and chat with over 300 models. A web search toggle lets any OpenRouter model pull live information — current events, prices, weather — charged to your own OpenRouter credits. Your computer's models with LM Studio Run open models in LM Studio on any Mac, Windows or Linux machine and use them from Chat LLM over a private Tailscale connection. Browse, load and unload models from the app, and connect LM Studio's MCP tool servers. No per-message credits, no content restrictions. Voice chat with Gemini Live and Grok Have natural real-time voice conversations through two backends. Google Gemini Live brings a choice of voices, Google Search grounding, and photo sharing mid-conversation. xAI Grok, now updated to Grok 3.0 real-time speech, adds a large, auto-updated voice library — use an API key or simply sign in with your xAI account. Each backend has its own system prompt and live tuning controls. Image and video generation Generate images and videos inside a conversation with OpenRouter and Grok media models. Prices show on the model cards before you generate, and generation keeps running in the background — you'll get a notification when your result lands, even if you've left the app. Reader — listen to documents and text Reader turns Chat LLM into an audiobook player for your own content. Import a .pdf, .epub, .docx or .txt file, paste text, or share any webpage or document from the iOS share sheet and Reader speaks it paragraph by paragraph. Tap any paragraph to jump to it; your position is saved automatically. Choose your voice per document from five providers: OpenRouter Kokoro for pennies, MiniMax for high quality at great value, ElevenLabs for expressive narration with your own cloned voices, Fish Audio for a vast library of community and custom voices, or xAI Grok — just sign in with your Grok account. Account voices sync automatically and can be searched and favourited. Export any document to a single audio file on your device. Pause an export any time and resume from the exact sentence — generated audio is never paid for twice. Exported files play offline with no credits used, can be shared or found in Files under Chat LLM, and keep sentence highlighting and tap-to-seek. iCloud sync Your settings, system prompts, conversations, and Reader library back up to your own private iCloud automatically and restore across your devices and after a reinstall. If you're signed out of iCloud, everything still works and stays on your device. Other features Image and document uploads in text chat (supported models) Independent system prompts per provider Advanced generation controls: temperature, top-p, and more Conversation history with model identification Vision, reasoning, and parameter-count tags on OpenRouter models Privacy Chat LLM does not require a user account. API keys are stored securely in the iOS Keychain. Your conversations and Reader library sync through your own private iCloud, tied to your Apple ID — they are never stored on our servers, and we have no access to them. When you use a third-party provider, your prompts and inputs are sent to that provider to generate a response; their own privacy and retention policies apply. Free to download. No subscription, no paywall. Optional provider usage is billed directly by the provider you choose.
