Acid

A manga series starring you and your friends: pick a scenario, add a selfie each, and Meta's Muse models write and draw chapter 1 in about four minutes. Then say what happens next. Acid turns you and your friends into the cast of a real Japanese-style manga. Pick a scenario card (or write your own), add up to four people with a selfie each, choose a style (shōnen, shōjo, seinen noir, kodomo) in black and white or colour, and about four minutes later you're reading a finished, lettered chapter with a designed cover. Friends can join from their own phones with a 4-letter table code. Then "what happens next?" writes chapter 2, 3 and on with the same cast. Publish to the community, where others read, like and comment, or continue a showcase series yourself. Live demo: https://acid-oneshot.vercel.app How it works (PDF): https://acid-oneshot.vercel.app/acid-how-it-works.pdf Challenges: Keeping real people recognisable across pages and chapters (solved by photo to fixed design to model sheet to every page as a sheet-referenced edit); making it genuinely Japanese manga rather than comic-book (mangaka-briefed writer, magazine-tradition styles, kana-only SFX); catching image-model mistakes automatically (a vision editor loop); and making a public demo safe to leave open (run tokens, caps, spend ledger). What's next: Acid is a manga studio we're building; this web version is its core loop rebuilt on Meta's stack. Next: readers funding the next chapter, badges, community translations, and the mobile app. Built during the event: All code was written during the hackathon (26 Oct – 4 Nov 2026). Brought in from before: Acid's visual language (colour tokens, type, button styles), a few art files, the halftone shader idea, and the logo. No app or pipeline code.
