TL;DR: Bygga turns flat-pack assembly into animated 3D steps, with AI-generated narration and optional AI help. Its useful design lesson is to give a model a narrow role around a reusable drawing engine. Its current user reports also show why a convincing diagram still needs checking against physical reality.

Separate the picture from the AI

Hassan El Mghari and Youssef’s independent project starts with a product name or article number. Code builds a plan of panels, fittings and assembly steps, then draws it as line art. The current README lists 1,171 products across UK and US ranges.

The core catalog and prerecorded Kokoro narration work without an AI key. Listening for spoken commands, photo lookup and optional help use the visitor’s own Together AI key. The paper-manual scanner remains on the roadmap; a promotional demo is not proof that it is ready.

The interesting detail is the help chat. Instead of asking a model to invent an explanatory image, it can point to an existing panel, fitting or step in the current guide. The renderer already knows how to draw those objects. That keeps the illustration tied to something inspectable, although the model can still choose the wrong thing.

Repeatable does not mean correct

The plan generator first tries a recipe for the furniture family. If none applies, it falls back to a generic furniture-type generator. That distinction matters more than the polish of the animation.

Users have reported physically impossible assembly steps, including dowels blocking the motion shown, and an incorrect leg count for a stool. Those issues are open at this writing. Treat the site as an experimental visualization and check the official IKEA manual for your exact product before assembling it.

A useful idea others can adapt

Contributor hansipie built Hackea on Bygga’s engine, adding furniture modifications and a 3D editor. Its source confirms the adaptation; that is evidence of useful reuse, not proof that either project’s designs are structurally sound. Hackea marks user-created guides as unverified and says measurements need checking before cutting or drilling.

The broader product lesson: use AI to interpret a request, keep the objects and steps explicit, and test the result against the task it is supposed to support. A well-formed plan and an attractive picture are only part of that test.
