The critique loop

Generate, score against real data, critique, repeat — a measured search, not a grid guess.

Pluggable backends

Any backend that publishes a pipeline definition is optimizable — read-only.

What it does

One prompt in. A population out.

Read the docs

PromptPotter treats your prompt as a program with tunable axes — and breeds, scores and critiques a population of candidates each round until your numbers move.

PromptPotter
Get started

It just runs. Pick who runs it.

It’s just I/O — hand it your prompt and your examples, hit run. It spins up on a machine and, if you’re lucky, hands back a better prompt in about five minutes. Full live monitoring the whole way — only if you want it. No schemas, no special code, nothing to wire up.

Our edge? An optimizer that evolves them.

PromptPotter evolves your prompts and pipeline params with a critique-guided loop — generate, score against real data, critique, repeat — plus posterior elimination and self-healing rails. It runs until your numbers move.

Free & open source

The whole thing is on GitHub.

No license keys, no seats, no paywall — the full source is public. Clone it, read it, run it.

The operator console

Watch every round, right in your browser.

When the loop is running, a read-only console streams the live pipeline, the candidate being scored and every round’s verdict — no extra tooling, no setup.
