-Anonymous braindump form + LLM synthesis for Inference Cooperative meetings.
+A benevolent robot that reads the co-op's anonymous pre-meeting braindump and
+tells the members what they said. Built for Inference Cooperative meetings.
 Members answer a short form before a meeting (ideas, wants, needs, goals,
 dissent). This script turns the export into a review document the group reads
 together: where energy is concentrated, what is unusual, where people disagree.

 synthesize button, same pipeline) is a possible next step if the output is
 useful. Discussion and ideas: open an issue here or on
 [co-op/support](https://git.inference.coop/co-op/support/issues).

+Why the name: it is a small experiment with a big-robot name, on purpose. The
+repo and command are `coopertron`; the 5000 lives in prose only.
