Renosaur is built around the reality that a renovation is chaotic: receipts get lost, nobody remembers what has already been bought, and partners end up arguing about spend. The app structures a project the way a house is actually built — room by room. Each room owns its own task list, budget and before-and-after photo pairs, so a kitchen remodel and a bathroom refresh never get tangled into one giant to-do list.
The standout feature is receipt capture. You photograph a receipt and Renosaur extracts the merchant, line items and totals, then files the expense under the correct room and project. Everything rolls up into an expenses report you can filter by project, room, tag or date, so you can finally answer the question "what did the kitchen actually cost?". A shared shopping list keeps both partners in sync while standing in the hardware store aisle, and a contacts section stores the plumber, electrician and tiler numbers where you need them.
Renosaur also ships an AI assistant called Rex. Rex knows your rooms, budgets and spending history, so you can ask practical questions like the correct order to demo a bathroom, or how much of the bathroom budget is already gone. Beyond answering, Rex can act — tell it to add a task and it appears on the right room's list. The company states you can start free with no credit card, add your first room in about two minutes, and export your data at any time.
