Talk to 100+ models with your own API key. Chain prompts into reusable Flows. Schedule runs and wake up to the results.
Thanks. We'll email you when it ships.
No subscriptions. No middleman. Your own API key, your conversations, stored on your device.
Anthropic, OpenAI, Google, xAI, DeepSeek, Meta, Perplexity, Moonshot. 100+ models in one place, swap mid-conversation.
Chain prompts into reusable workflows. Pipe one model's output into another's input. Save inputs once, run forever.
Daily digests, weekly reviews, recurring research. Flows fire on a schedule and notify you when results are ready.
Send one prompt to multiple models at once. Spot the best answer for the task instead of guessing which model to pick.
Your API key lives in iOS Keychain. Conversations stay on-device. No analytics, no telemetry, no account.
Toggle web search per chat for grounded responses with citations. Or stay fully offline-of-record. Your call.
Four steps. No accounts to create, no servers to trust.
Paste your API key into Settings. It's stored in iOS Keychain. Never sent anywhere except the model provider you're using.
Switch models mid-conversation. Compare answers side-by-side. Attach images. Toggle web search when you need real-world grounding.
Turn a chat into a reusable Flow with named inputs. Chain steps so one model's output feeds the next. Run it whenever you need it.
Daily, weekly, or custom intervals. Your phone wakes the Flow, runs it, and notifies you with the result. Wake up to your morning brief.
Honest about where we are and where we're going. No promised dates, just direction.
Anthropic, OpenAI, Google, xAI, DeepSeek, Meta, Perplexity, Moonshot. Plus 90+ more models from the same gateway. Multi-step Flows, scheduled runs, side-by-side compare.
Native macOS companion. Same Flows, same monochrome design, full keyboard-driven workflow. Sync your chats and Flows across devices.
Hugging Face Inference and additional model gateways alongside the existing eight. We add providers as they prove genuinely useful, not just because they exist.
Add any OpenAI-compatible endpoint with a base URL and API key. Local servers (Ollama, LM Studio, vLLM), self-hosted deployments, or providers we haven't built into the picker yet.
Optional. Skip the API keys: one subscription covers a managed bundle of models. The free, bring-your-own-key version stays exactly as it is.
No OpenChat account. You bring your own API key. That's the only sign-up. We don't store user accounts, telemetry, or analytics.
OpenChat is free. You pay your model provider directly at their published rates. We never see your usage or charges.
On your device, in the iOS sandbox. Nothing is uploaded to our servers. We don't run any. Your data lives only where you can see it.
You can browse past conversations and edit Flows offline. Sending a new message requires the network. That request goes straight to your model provider.
A Flow is a saved sequence of prompts with named inputs and configurable models per step. Think of it as a chat you've parameterized. Fill in the blanks and run it on demand or on a schedule.
100+ models, including Claude (Anthropic), GPT (OpenAI), Gemini (Google), Grok (xAI), DeepSeek, Llama (Meta), Sonar (Perplexity), Kimi (Moonshot), and others.
