The finding
It can build anything.
It can’t tell you what.
Your agent knows your code. It doesn’t know your users, your numbers, or what matters next. That’s a product manager’s job.

The AI PM your coding agents need
Your agent builds.Nano decides.
Claude Code and Codex build whatever you ask. They don’t know your users, your numbers, or what to build next. NanoPM does: it reads the signals, decides with a PM’s judgment, and hands the work to your agent.
nano.pmstill watching01 · What changed
Building got cheap. Deciding didn’t.
A coding agent ships in an afternoon what took a team a quarter. The bottleneck moved. It’s no longer writing the code.
It’s knowing what to write, in what order, and whether it worked. That is a product manager’s job, and for most builders it’s still done by hand, or not at all.
02 · The problem
You code. Nobody steers.
A live product emits signals all day: logs, usage, payments, feedback, churn. Reading them, turning them into a decision, and acting on it is a product manager’s job.
Nobody does it for a side project. So you ship on intuition, find out about churn too late, and your agent builds the wrong thing very fast.
03 · Your product on autopilot
Reads. Decides. Does.
- 01
Reads the signals
It queries the tools you already have: your database, your logs, PostHog, Stripe, the support inbox. No instrumentation, no dashboards to build.
- 02
Decides what's next
A ranked list of actions, each with its reasoning and its evidence. You accept, reject, or correct. A rejected idea only comes back with new proof.
- 03
Does it with your agent
Accepted actions run through Claude Code or Codex, on your machine, on your subscription. It proposes first, executes on your go, and runs on autopilot when you say so.

04 · What it is not
Not another tool to feed.
Not a documentation tool.
No PRDs, no briefs, no wikis. Decisions and actions only.
Not a project management tool.
No tickets, no sprints, no boards. The roadmap is a prioritized list of actions.
Not an analytics tool.
It reads at the source and keeps only what it learned. No dashboards to maintain.
Not a coding agent.
It decides what yours should do, then hands off to it.
Not a process.
No methodology to learn, no rituals to follow. You ask, it answers and acts.
