Use Claude, ChatGPT, and Gemini from one app. Your context, preferences, and API keys travel across every model — encrypted so only you can read them.
Join as a founding member — $129You probably use more than one AI. Claude for writing, ChatGPT for code, Gemini for research. Each one lives in its own app, with its own memory, its own context, its own subscription. Every time you switch, you start from zero.
Your preferences don't carry over. Your instructions don't travel. The context you've built up with one model is locked inside that model's app. And all of it — your prompts, your history, your habits — lives on someone else's servers, under their terms.
Own Your Brain fixes both problems at once. One app for every model. Your memory and context are portable. And everything stored — your keys, your memory, your history — is encrypted so that only you can read it. We never see your conversations. They go straight from your browser to the AI provider.
Everything you need to use AI on your terms.
Chat with Claude, ChatGPT, Gemini, and more from a single interface. Pick the right model for the job. Switch mid-thought without switching apps.
Tell Own Your Brain who you are, how you work, what you care about. That context rides into every conversation with every model. No more re-explaining yourself.
Bring your own API keys. Pay providers directly for what you use — no middleman markup. Your keys are encrypted and never leave your browser in plaintext.
See exactly what each provider can and can't see. Toggle memory per provider. Every privacy claim is verifiable in the app, not buried in a policy doc.
Own Your Brain uses your own API keys to talk to AI providers directly. That's what keeps your data private. Getting a key takes about 2 minutes — and we'll walk you through it.
You know the drill. Add your Anthropic, OpenAI, or Google key to the vault. It's encrypted instantly and you're chatting in seconds.
Sign up → paste your key → go.
No problem. When you sign up, we'll walk you through getting your first API key step by step. It's free to create an account with any provider — you only pay for what you use.
We never see your conversations. Your keys and memory are encrypted so only you can read them. When you talk to an AI, the request goes from your browser directly to the provider — our server is never in the path.
We don't ask you to trust us. We'll show you exactly where your data lives.
API keys, memory, and conversation history are encrypted in your browser before they ever touch a server. We store ciphertext we can't decrypt. Not "we choose not to" — we architecturally cannot.
When you send a prompt, your API key is decrypted in-browser and the request goes straight to the provider. The AI has to see your prompt to answer — but our server never does. You can verify this in your browser's network tab.
500 spots at a lifetime price. Then it's $9/month for everyone else.
You pay each AI provider directly for what you use through their API. For most people, that's $2–10/month depending on usage — often less than a single $20/mo subscription. Own Your Brain is the app layer; the $129 covers it forever. There are no hidden fees or per-token charges from us.
During setup, you'll get a 12-word recovery phrase — like a crypto wallet. Write it down or print it. If you forget your password, the phrase recovers your vault. We never see the phrase. If you lose both, your vault is unrecoverable by design — that's what zero-knowledge means.
We're launching with founding member access only (500 spots). Once those fill, new users will have a free tier with one model and basic memory. Founding members get everything, forever.
Export your data anytime — one click. Clear your vault, clear your memory, delete your account. We don't make leaving hard because we don't want to be the kind of product that needs to.
Not yet, but the trust architecture is fully auditable from your browser. Open dev tools, inspect the network tab during a chat — you'll see zero requests to our server. Every privacy claim is verifiable, not just promised.
