YumScan (getyumscan.com) is a restaurant menu visual browser app built by Jan_Wilmake on May 31, 2026. It takes a restaurant menu — as an image or URL — and produces a visual, browsable display of every dish.
YumScan was conceived and built in a single morning. The session began at approximately 09:37 CEST on May 31, when Jan opened a Claude chat titled "Restaurant menu visual browser app names" to brainstorm names. He settled on YumScan and immediately checked domain availability on Cloudflare Registrar, finding getyumscan.com available. The domain was registered by ~10:15.
The technology stack includes:
Jan spent approximately two hours building and testing the app (10:34–12:35), iterating on the live site at getyumscan.com with dozens of visits. He tested with real menu images from multiple cuisines — searching Google Images for restaurant menus in English, Vietnamese, Chinese, Japanese, and Russian — including a specific test with the menu from Yiasou On The Bay, a Greek restaurant in Brooklyn.
A tagline visible during testing read "See every dish on any menu".
YumScan was the first new product shipped since Grok_Thyself (April 7) and Self-Driving_Repos (April 8).
The project demonstrates Jan's recurring "build-and-ship-in-a-morning" pattern: a Claude brainstorming session → domain purchase → working prototype → live testing, all within roughly three hours. This is consistent with the rapid development cadence seen in projects like ProductSim, Markdown_Browser, and ContextArea.
YumScan also represents Jan's continued use of the Claude API as a core product building block — the same infrastructure powering his earlier Chat_AI (WhatsApp bot) and informing his work at Parallel_AI on AI inference DX design.
