ArtistDeck
Evidence-graph EPK generator for musicians
A press-kit generator where every published claim has to trace back to a verified source before it can ship.

System Trace
The path from the real brief to the result, with no simulated agent status.
- 01
Brief
Press kits that cannot carry a claim nobody checked.
- 02
Structure
A provenance-tracked evidence graph; the EPK, PDF and buyer kits are views of it.
- 03
Verify
Both known failure classes are blocked at the write path and covered by tests.
- 04
Shipped
Live and pre-launch, so no user or revenue figures are claimed.
02The problem
An independent artist rebuilds the same press kit every time a promoter asks, and it is stale by the next release. Tools that promise to fix that write confident copy and check it against nothing, so the failure is not a clumsy sentence. It is a false credential sent to a buyer.
This project produced two of those before the rule that prevents them existed. A distributor was stored as a record label. A copyright line wrote an artist's legal name into a public field, for an artist who performs under an alias. Both rows were marked verified.
03Build
Setup is a name. The system searches Deezer, SoundCloud, Apple Music, Last.fm, YouTube, Mixcloud, Bandcamp, Resident Advisor and Linktree, and the artist confirms or drops each match before anything is written. A wrong match at the first step contaminates the whole profile.
Claims are ranked by how close the source sits to an explicit statement. A label field or a Discogs credit is strong. A copyright line or a distributor credit is weak, and a weak claim stays at needs-source until a different, strong source confirms it. A name filter was the obvious fix and was rejected, because it catches nothing when the artist uses an alias.
It runs on Next.js 15 and Supabase Postgres, with row-level security doing access control. Generated copy is checked against content rules and regenerated when it fails.

04Result
Live at app.artistdeck.press. Both failure classes are blocked at the write path and covered by tests, and a row holding a person's legal name is deleted rather than downgraded.
The product is pre-launch, so no user or revenue figures are shown.
05Role
- The product thesis: the verified evidence graph is the asset, and every kit is a projection of it.
- Corroborate-then-promote as the provenance rule, after rejecting a name filter.
- The press-kit design system, its print export, and the content rules the generator enforces.
- The schema, the access-control model and the provenance rules, specified to the point of being testable.
- Most implementation code was written by AI coding agents from my specifications and under my review.
- Bios are model-generated on request, then checked against the content rules and regenerated when they fail.
- Next.js, React, Tailwind CSS. Supabase, Stripe, Playwright.
- Hosted model APIs on a fallback chain. MusicBrainz, Discogs, Beatport and Spotify as source data.
