Renofine
Renaida turns a sentence, a receipt and a quote into a project with a budget. Tap it to try it live.
The drawing tool on the public example flat: floor plan, 3D, and an AI check of the drawing. Open the example flat ↗
Software for planning and running a home renovation. Describe the job or draw the flat, and Renaida, the AI colleague, turns it into rooms, tasks, a budget and the Swedish tax deduction. The builder, the homeowner and the tradesperson each get their own screens. Ten languages.
What I had to get right
-
Three users, three sets of screens. Each role gets its own screens. Mixing user types in one view is a cost you pay forever.
-
Floor plans in real-world units. The drawing tool works in millimeters, not pixels. Zoom in, zoom out, change a setting, and the math still works because the units are real.
-
Locked-down database access. Two simple checks decide what each user can see. Every database change gets tested from two angles: the owner's view and an invited user's view. Catches the most common security bug in this kind of app.
-
AI that suggests, never pushes. Drop a quote PDF in, get a project draft. Ignore every suggestion if you want. The AI offers; the user decides.
-
Ten languages kept in sync. English is the source. Swedish is required. The others are best-effort. No raw text hardcoded into the screens, ever.
Built with: React and TypeScript for the screens. Supabase for the database, login, and file storage. Konva for the drawing tool. Cloudflare to host it. Claude and OpenAI for the AI helpers.
