Week 4 of Summer into AI 2026 hosted by @advisoryhour — theme: Built on Yesterday.
Complaint Storm animated real CFPB complaints as a particle storm and let two AIs argue about it. Class Action makes the storm your case. Name a company, and the AI clusters its real federal complaints into candidate legal exhibits. You pick three. Then an AI defense attorney attacks your specific selections by name, you write the closing rebuttal, and an AI jury returns a verdict — exhibit by exhibit, with damages.
Worth noting alongside this: Eric's Chicago Art Dataset (Week 3) made a public dataset browsable and beautiful. Class Action makes a public dataset something you litigate — the records become exhibits, and your selection strategy decides the verdict
Built on yesterday — what changed
The original: Complaint Storm (Week 3) — you watched two AIs argue about the complaints — you had no say
Player agency: the AI clusters real complaints into candidate exhibits, but YOU build the case — pick three, and strong-but-few versus weak-but-many is a real strategic choice
The AI defense attorney reads your specific exhibits and attacks them by name, streaming with visible extended thinking
You write the closing rebuttal yourself; the AI jury weighs it explicitly in a structured verdict — sustained or dismissed per exhibit, with damages awarded
Upgraded CFPB integration: fuzzy company resolution and narrative-bearing complaints (a fix the original never had)
How the AI works
Discovery clustering — real CFPB complaints are fetched live and clustered by a forced tool call into 5-6 patterns, each with complaint counts, a strength rating, a sample narrative, and a legal theory.
Adversarial defense counsel — a streaming call with extended thinking reads your three exhibits and dismantles each by name: thin counts, causation gaps, statute-of-limitations problems.
The jury — a final structured verdict rules on each exhibit separately, weighs your written rebuttal, and awards class damages that animate up from zero.
How to play
Name a defendant — Wells Fargo, Equifax, any company in the CFPB database.
Review the discovered patterns and select exactly three as Exhibits A, B, and C.
Survive the defense. Then write your closing rebuttal and send it to the jury.
Read the verdict card by card. Sustained exhibits pay; dismissed ones teach you what a stronger case looks like.
