The best AI for anything you ask.
Zeno is powered by the world's most advanced AIs, Claude, ChatGPT, Gemini and more. Ask it anything and it picks the right one for you, then charges a few cents. No subscriptions to juggle.
No card needed. Ask your first questions on us.
One app for the hundred little jobs in your day.
Whatever you need, Zeno quietly hands it to the AI that is best at it. You never pick a model or learn a setting. Here is what that looks like.
It remembers, plans and does real work for you.
Zeno is more than a chat box. It keeps track of what matters to you and your business, and gets things done between conversations.
Tell it once. It never forgets.
Your preferences, your projects, your customers. Zeno brings the right details back automatically, so you stop re-explaining yourself every time.
A quick morning catch-up.
Set it once, it just runs.
Weekly reports, follow-up nudges, a research check every Monday. Zeno does the task and lets you know when it is done.
Write it together.
Draft letters, proposals and posts side by side, then tidy them up in seconds.
Describe it, get it.
Say what you want and Zeno builds you a real, live web page.
Make the picture.
Logos, social posts, product mock-ups, generated from a sentence.
Pay for what you ask, not for four subscriptions.
Everyone gets 50 free credits every month. After that you top up from a single dollar. Most answers cost a credit or two, so a little goes a very long way.
$1 = 50 credits · $3 = 200 · $5 = 500 · no monthly lock-in, cancel by simply not topping up
The most advanced AI, on your side, not Big Tech's.
You get the same models the giants use, without the lock-in, the dark patterns, or your life being quietly used to train them.
You choose what is shared
Nothing goes to an AI until you say yes. It is enforced properly, not just a box on a screen.
Your data stays yours
Your conversations are never sold and never used to train models behind your back.
No trap, no lock-in
There is no subscription to forget about. Stop topping up and you simply stop paying.
Always the real thing
You get genuine access to leading models, and you can see which one answered you every time.
Building something? There is an API too.
Developers can point any OpenAI-compatible app at Zeno and get the same smart routing behind a single key. Pay per token, same as the app.
Read the developer docscurl https://zenoknows.com/api/v1/router/chat/completions \ -H "Authorization: Bearer $ZENO_KEY" \ -H "Content-Type: application/json" \ -d '{ "messages": [{ "role": "user", "content": "Hello" }] }'
Powerful AI that doesn't need to know who you are.
No password to leak, no ad profile, no name attached to the models you talk to. Zeno is built so you can think out loud without being watched.
Sign in without a password
Zeno uses passkeys and one-time email links — there is no password to steal, reuse, or leak in a breach.
Anonymous by default in the community
Post a question and other members see only your initials — never your full name or email.
Stripped before it teaches our router
Any prompt used to improve model routing has emails, numbers and account IDs removed and replaced with content hashes — no row traces back to you.
No tracking, no ad cookies
We run no third-party analytics and no advertising cookies. Your identity is never sold to build a profile of you.
Nothing shared without a yes
No message reaches an AI provider until you consent, and providers never receive your email, payment details, or account info.
Erase yourself anytime
Delete individual memories, exclude conversations, or remove your account entirely — one tap in Settings, no email tickets.
Give your day the world's best AI.
Every top model, the right one picked for you, for a few cents a question. Start with 50 free credits, no card needed.
