Portals links 471 generated worlds into a browser journey

In Portals, each doorway leads to another world. The project describes a human-directed AI creation with 471 generated 3D scenes in its November 9 snapshot, linked into an automatic browser journey. Experience: https://portals-endless-worlds.netlify.app/ .

Ethan Mollick says he gave Claude Fable 5.2 the premise, then supplied location ideas, feature requests and feedback. According to his account, 204 worlds were online after twenty hours. That was an early milestone, not the total development time.

Rather than playing prerecorded animation, the project says its browser code generates scene geometry, textures and sound. Smooth operation across every world remains independently unverified.

Mollick had unmetered tokens during early access; the equivalent cost for ordinary users and the final total duration are undisclosed. GitHub showed 165 stars and 37 forks when checked. Those numbers are not an audience count. The interesting shift is a production process in which a person directs and AI builds a large collection of scenes.

Source dates: the creator’s article and repository snapshot say November 9, 2026, without a publication clock or timezone; the corresponding Beijing and US Eastern dates remain unverified. The experience page provides no publication time. Repository counts were checked November 13, 2026, at 17:32 Beijing / 4:32 AM EST.
