AI-refined assets are souring the vibe around Librarian: Tidy Up the Arcane Library

Librarian: Tidy Up the Arcane Library — a cozy game where you sort 3,072 books scattered across a fantastical library floor — started climbing Twitch charts in early May and hit 29,000 concurrent players. It was built by a two-person indie team called ArtRising, and the reception was warm right up until people noticed a disclosure buried at the very bottom of its Steam page: the developers used generative AI for asset refinement and grammar corrections.

Specifically, four assets were AI-refined — one UI component and three landscape paintings used as wall decorations — and AI also helped with in-game text grammar, which the team says was then reviewed and adjusted by hand. ArtRising insists nothing was generated from scratch by AI and that human craftsmanship drives the whole project. Some players aren't buying it. One Steam reviewer wrote that after spending hours picking up books and reading titles, they flatly don't believe all the covers and titles were made by people. Another said they suspect more AI was used than disclosed for things that could have been done by actual humans without much trouble.

The backlash has been real but uneven. Several streamers cancelled planned streams after learning about the AI use — Janken Pomme posted publicly on X that their stance on AI is clear, they won't support it in any form, and they were issuing a refund. Reddit threads popped up asking for AI-free alternatives, and ethics debates are still running hot. At the same time, the game holds a Very Positive rating on Steam, plenty of people are still playing it, and even Aftermath — a publication that literally sells anti-AI merch — ran a favorable piece on it.

The frustrating part, as Kotaku points out, is how easily fixable this would be: just one UI element and three paintings. Stock images or even placeholder art would sidestep the whole controversy. The bigger worry is what happens if Librarian keeps selling well without swapping those assets out — other cozy devs might read that as permission to lean harder into AI themselves.
