A morning briefing, in Zeno's voice

One tap and Zeno reads you a 3-minute briefing built from this morning's news on the topics you actually care about — grounded in real sources, not vibes. Every brief is archived with the links it was built from.

Crowd-routed AI

Use the crowd to power your chats.

Zeno Route is the smart routing layer that's been learning from every chat across the Zeno community. Real user preferences decide which model handles which kind of question — so your app gets the right answer without you having to pick.

  1. Powered by every Zeno chat. Routing decisions reflect what actually works for real users — not a hardcoded rules table. The more the community chats, the sharper the routing gets.
  2. $0.005 per routed call. 200 calls per dollar. The first 200 calls each month are free, on us.
  3. OpenRouter pass-through. Token cost passes through 1:1 — no markup. Bring your own OpenRouter key and you only pay the routing fee.
  4. OpenAI-compatible drop-in. Same shape as /v1/chat/completions. The response carries an extra zeno block telling you which model was picked and what it cost.
