Build an agent, step by step.
Seven steps between a blank prompt and something people pay to use. Click through them and watch the agent come together.
Brief it, then pick its brain.
Instructions in plain language, and the model that runs them.
System prompt
Model
Write what it should do the way you'd brief a new hire, then choose the model it thinks with.
Where you are
Why the gate holds
Three decisions outside the creator's control.
Risk tier
You don't pick your own difficulty
We work out how risky an agent is from how it's set up. Build something that gives financial advice and you get the strict bar, whether you want it or not.
source
“Retention is set per control owner.”
answer
“Retention is always 12 months.”
Groundedness
Retrieval isn't the same as truth
Pulling up the right document isn't the same as using it. A second model checks the answer against the sources and fails it when they don't line up.
Fingerprinting
A pass expires when you edit
A passing score belongs to the version that earned it. Edit the prompt afterwards and you'll need to run it again.
The runtime
What runs it once you ship.
gateway
One integration, every model
You don't collect API keys. Pick from the list and switch whenever you like.
0 tokens lost
Nothing gets lost
Wifi cuts out mid-answer and it picks up where it stopped. Same if someone closes the tab.
Storage you don't run
Upload your files and forget about them. We index them and handle the searching.
Billed by the message
Every message is priced, charged and logged as it happens. You can read every line.
Shipping next → Export & SDK
Run it anywhere. Meter it here.
Soon you'll be able to put an agent straight into your own product and still bill for it through Kopai. Same wallet, same payouts, same ledger. Join the waitlist to get early access.
Pricing
Simple pricing for people who ship agents.
Organizations start free. Upgrade when the gate, the runtime and the ledger are carrying real work.
Free
