Why ZDR Chat?
Privacy-first by design. No compromises.
Bring Your Own Key
Paste your OpenRouter API key. It's stored in your browser only. Never sent anywhere except directly to OpenRouter. We never see it.
Pay-as-You-Go, No Subscription
No monthly bills. Add as little as $1 to OpenRouter and it lasts until you spend it. The status bar tracks every cent.
Zero Servers
No backend. No accounts. No sign-up. The entire app runs in your browser as a static PWA. Hosting costs us ~$0/month.
Zero Data Retention
Every message and setting stays in your browser's IndexedDB. We don't store your conversations — we can't; there's nowhere to put them.
Honest Pricing
The only thing you pay for is the model. No subscription, no markup, no data mining.
Pay OpenRouter Directly
You add credit to your OpenRouter account. We never touch your money. No markup, no platform fee, no hidden charges.
Track Every Cent
The status bar shows tokens in/out, session cost, and remaining credit. You always know exactly what you're spending.
Free Models Included
Dozens of $0 models are available (rate-limited). Try the app without spending a cent — then add $1 when you want premium models.
We're not affiliated with OpenRouter. We don't earn commissions, resell tokens, or track usage. The app costs us ~$0/month to host — we built it for privacy, not profit.

The ZDR Pledge
Zero Data Retention
ZDR (Zero Data Retention) means exactly that.
Your conversation history lives in your browser's IndexedDB. Your API key is stored locally. We run no servers, maintain no databases, log nothing.
Configure privacy enforcement at the OpenRouter account level, and every request is ZDR-guaranteed at the network layer.
We have no financial stake. We're not affiliated with OpenRouter.ai. We don't earn commissions, resell tokens, or track your usage. The app costs us ~$0/month to host on Cloudflare's free tier. We built this because private AI should be accessible — not for profit.
