Hey Product Hunt 👋 A choil is the small unsharpened notch where a blade's edge stops and the ricasso begins. If you already knew that, this was built for you. Collectors can rattle off the steel, the lock, the grind and the heat treat on every piece they own. Ask what the collection is actually worth and it falls apart — the real price signal lives in completed sales scattered across forums, live auction streams, and listings that vanish a week later. CHOIL is the vault built around that gap. 🔪 Catalog properly — steel, grind, lock, handle, dimensions, provenance. Add pieces by photo, barcode, product link, or bulk spreadsheet import. 💵 Real valuations — from completed secondary-market sales, with outliers rejected. You get a median, a low/high band, a confidence score, and the sources it used. Not a vibe. 📊 Steel as data — every blade steel renders as a live performance radar (edge / toughness / corrosion / sharpenability) against a common baseline. The blueprint redraws itself too: a tanto and a hawkbill don't share a silhouette. ✨ The Curator — an AI that actually knows your vault. It values pieces, fills in factory specs, and writes a blunt read on the whole collection: its strengths, its gaps, and the one piece that would level it up. 📈 Market intel — a ~1,600-product reference catalog across 120+ brands, drop tracking, brand follows, and price/stock watches on any product URL. 🤝 Trading Post — members post WTS / WTT / ISO and attach a piece straight from their vault. Deals happen directly between collectors; CHOIL never touches the money. 🎯 Snipe — a browser extension that pins CHOIL's sold-comp value over a live auction stream, with a deal meter that flips green the moment the bid is a steal. The vault itself is free, on web, iOS and Android — cataloging, wishlists, the Trading Post, all of it. Credits only get spent when you ask the AI to do something, and prices are identical across web and mobile. The valuation engine is the part I most want feedback on: if you collect, throw a piece at it and tell me whether the number matches what you'd actually expect it to sell for. That's what I most want to get right. — Pat
