Manifest is a home inventory app that builds itself from a photo. Snap a picture, forward a receipt, or say what you bought, and it pulls the brand, model, serial number, warranty, and return window, then files it for you. So when something breaks and the warranty wants proof of purchase, a return window is closing, or an insurance adjuster wants a list, you already have it. On web, iOS, and Android. Free trial, then plans from $1.99/month.
