Muse Studio Lite is an AI ad agency for one-person businesses that works on Meta's real ad platform and cannot spend a cent without the owner's signature.

The owner describes the business in their own words; Muse Spark turns that into Brief v1 and asks only the [FACT] questions it needs (prices, guarantees, what is included). Seven Muse agents then plan, write, draw, cut out, review and report: Producer, Copywriter, Art director (Muse Image + SAM 3.1 cut-outs), Reviewers and Analyst. Reviewers block any claim the owner never confirmed (no invented "free" or prices) and the producer rewrites it.

Nothing goes live on its own. The owner signs the exact bytes of the campaign in the browser with an Ed25519 key that never leaves their device; then code, never a model, creates the Facebook/Instagram campaign through the Marketing API, PAUSED. Every step leaves a hash-chained receipt that anyone can verify offline with "studio verify" (600/600 tampered exports rejected, 247/247 attack tests pass, about $0.09 per campaign run).

Live sandbox for judges: https://muse.udun.eu (login: judge, password: y24bv-bx8cs-xvpsf-sy3np). The 60-second judge path is at the top of the README; what was built during the event, with dates from git, is in HACKATHON.md.
