Built this with Lovable.dev using pure vibe-coding prompts because I hate typing out prices manually after shopping. The dream core flow: open app → snap photo of receipt → AI extracts product, price, store, date, location → confirm if needed → save. Done in seconds. No forms, no hassle.

Right now it's more basic but live:

Upload receipts to contribute (goal is full AI auto-fill from photo) Browse prices, see history, compare locations to spot where it's cheaper Create shopping lists with estimated totals Set price drop alerts (email notifications) Current stats (mostly seeded + a few real): 1.0k prices tracked, 6 contributors, 66 stores, 36 savings found (e.g. LEGO set dropped RON 1 locally) Free account to add/view (quick sign-up), no ads/paywall. Community angle: crowdsource real paid prices so anyone can avoid overpaying on groceries, electronics, whatever—especially across countries or stores.

Vibe-coding let me iterate fast: describe "receipt photo upload with AI extraction" → Lovable generates → tweak prompts → repeat. Still rough edges (e.g. upload isn't full AI yet, feels sparse with low contributors), but that's why I'm posting.

Curious what HN thinks:

Does the receipt → AI flow sound useful enough to contribute on impulse? Biggest friction right now (sign-up wall? No guest adds? Looks empty?) Would "I paid the same!" quick buttons or weird-price leaderboards help retention? Privacy thoughts on shared receipt photos/data? Or is this just not an itch people have?
