Web demo · on-device

See the room.
Place the future.

Jarvis by B turns your phone camera into a room-scan playground. Describe what’s there, then drop virtual chairs, lamps, plants and more — right on the live view.

Try the live demo How it works

🔒 Camera feed stays on your device in demo mode. No account required.

Built for the scan → place loop

A focused demo of the core idea — not a store listing, not a marketing claim. Open it, allow camera, try it.

📷

Scan the room

Live camera with a scan sweep. On-device heuristics guess lighting and region labels from the frame.

🗣️

Hear the read

Optional voice readout of the scan. Tap to mute anytime. Clear, short, useful.

🪑

Place virtual items

Chair, lamp, plant, screen, robot, or a text label. Drag to move, tap ✕ to remove.

How the demo works

Honest about what it is — a polished prototype you can share today.

1
Allow cameraBrowser asks once. Front or rear via Flip.
2
Scan roomDemo mode analyses brightness, colour and edges in a 3×3 grid — labelled “DEMO — not real AI”.
3
Place & arrangePick an item, tap the view, drag it around. Clear when you’re done.
4
Optional live API⚙ API can wire an OpenAI-compatible vision endpoint. Only then is a frame uploaded — your key stays on-device.

Privacy by default

In demo mode the camera never leaves your phone. Nothing is uploaded unless you connect a vision API yourself.

Installable as a PWA from the app screen (Add to Home Screen).

Independent project. Not affiliated with Marvel, Disney, or any other “Jarvis” product. Full store name: Jarvis by B.

Demo mode uses simple on-device image heuristics. It is not computer vision or a trained model. Live mode only activates if you paste your own API details.
