Milin · the product mill · private early access
Grain in.

A mill of AI agent workflows that turns your repo, PRD or mockups into finished, machine-verified deliverables, with your AI cost shown raw, in USD, while it runs.

you approve at the gates, humans stamp, machines grind
Your key, your bill. Inference runs on your own AI API key, at cost, in USD, in the open.
Verified by the machine. CI green, events observed, sandbox transactions passed, before you're asked to accept.
Not a chatbot. You assign objectives, watch the run live and approve at gates. There is no prompt box.
01 · How it works
You supervise a small factory.
You don't chat with it.
STEP 1
Assign an objective
Pick a brick, point it at your grain, repo, PRD, mockups, and set a budget cap.
○ DRAFTSTEP 2
Watch the mill run live
Every agent role, every artifact, every cent of inference, streamed as it happens.
RunningSTEP 3
Approve at the gates
The run pauses at every decision that matters. Paused means paused, no tokens spent.
Gate waitingSTEP 4
Receive a verified deliverable
Delivered only once the platform has proven it works, not once an agent says so.

02 · Radical cost transparency
Your inference, your key,
your bill, in the open.
You bring your own AI API key, Anthropic Console, AWS Bedrock or Google Vertex. Milin runs inference on it at cost, and shows you every dollar as it's spent. No credits. No compute units. No markup hidden in a token bundle.
So why pay €349 for what looks like $10 of inference? Because inference is the flour, not the mill. You pay for orchestration, machine verification, gates, and a deliverable you can put in production, the AI cost itself passes through untouched.

03 · The bricks
Five millstones. Each one a machine.
A brick is a workflow of agent roles with gates where you decide. No faces, no first names, names are for the humans who approve.
Analytics
first brick · shipping at launch
repo + goals form → audit → tracking plan ◆ gate → implementation PR → PostHog / GA4 provisioning → dashboards
✓ verified: every declared event actually observed in the target tool
Build
web & mobile
PRD + mockups → iterative build in PRs → QA → staging ◆ gate → prod
✓ verified: CI green on every PR, staging exercised before prod
Growth
recurring wake-ups
funnel audit → experiment backlog ◆ gate → A/B tests + landings → periodic wake-ups with proposed adjustments
✓ verified: every experiment measured live before conclusions
Payments
money touches nothing unverified
pricing design ◆ gate → integration → sandbox test ◆ gate → prod
✓ verified: a real sandbox transaction passed end-to-end
Monitoring
the mill that never sleeps
baseline ◆ gate → periodic wake-ups → incident detected → report ◆ gate → GitHub issue
✓ verified: every incident traced to a reproducible issue
More millstones being cut
The mill grows brick by brick. Follow what's being carved in the build log.
04 · Verification = trust
An agent never declares
its own work done.
Verification belongs to the platform, a third actor that trusts no one. A deliverable ships only when the machine has watched it work: pipelines green, events flowing, money moving in the sandbox. Then, and only then, is a human asked to approve.

The terms
No free trial, the build log is the permanent demo. Monthly, cancel anytime, unlimited seats. You bring your own AI keys, inference is billed in the open, on your account, with zero markup.
06 · Build in public
The mill is built
in the open too.
No trial, no demo call, instead, the whole workshop journal. What we're grinding, what broke, what it cost us.

07 · FAQ
Fair questions
Why is there no free trial?
Because the demo never closes. The build log shows real runs, real costs and real failures every week, more than a 14-day sandbox ever would. When you subscribe, you get a working mill from day one, and you can cancel monthly.
Why bring my own API key? Can't I use my Claude Pro plan?
Consumer subscriptions don't cover API inference, the mill needs an API key from Anthropic Console, AWS Bedrock or Google Vertex. That's a feature: inference lands on your account, at provider cost, and Milin never marks it up or hides it in credits.
What exactly does “machine-verified” mean?
The platform, never the producing agent, proves the deliverable works: CI pipelines green, every declared event observed in your analytics tool, sandbox transactions passing end-to-end. The check log ships with the artifact.
Is this another AI app builder?
No. App builders generate, you debug. Milin substitutes for a dev agency: it ships verified deliverables into your repo, your analytics, your payment stack, under your approval at every gate. You're not paying for generation, you're paying for governance.
Can I cancel? Are there refunds?
Cancel anytime, your plan runs to the end of the month. No refunds, and no lock-in either: everything the mill produced lives in your repos and your tools, and leaves with you.
Do agents ever act without me?
Never past a gate. Anything that touches production, money or your customers pauses and waits for a named human to approve, and a paused run spends nothing.
