I've missed out on an awesome computer that I could use for a project because figuring out value took too long. Users paste a listing and receive a value grade, dated component estimates and a shareable report. AI reads the listing but my custom built price engine determines the grade (updated every day). Self financed and working now. Looking for feedback re: scoring, interface, and if its helpful. https://www.youtube.com/watch?v=Tpft--x3WlI

Could you build this?
Partial The listing parser, report page, and grading UI are vibe-codeable, but the grade depends on a continuously refreshed database of component prices that the builder must collect and maintain.
What it would actually take: The stack would be a web app plus an LLM for parsing listings, with a scheduled scraper or price-feed pipeline feeding a component pricing database. The hard part is building and keeping accurate, dated component prices across many retailers and used markets, which requires ongoing data collection, deduplication, and sanity checks. A solo builder can start with a limited set of parts and scale up, but the grading quality depends on that proprietary dataset.
