Saber Denies Replacing Rideshare Stimulator Writers with ChatGPT
Saber Interactive’s CEO says no writers were replaced by AI on Rideshare Stimulator — while the former lead writer says she was swapped out mid-development.

Saber Interactive’s chief executive has pushed back on claims that the studio used ChatGPT in place of human writers on the newly announced Rideshare “Stimulator.” The dispute follows a post by former lead writer Stella Sacco, who said on Bluesky that she was replaced “midway through development” and that “all the passenger voices were AI too.”
CEO Matthew Karch told The Verge that “Neither Saber nor Unigine have replaced any writers with AI,” adding that the game’s main story was “written entirely by real people” except for an “experimental, free-ride mode” that uses AI because “the number of passengers in the game is infinite.” He said Saber has used AI tools to enhance gameplay and NPC behavior and emphasized that the company continues to hire, noting its more than 3,000 employees are not at risk of being replaced by AI.
A disputed account of how the writing was done
Sacco disputes that account. In a message to The Verge she said labeling the story as wholly human-made while acknowledging AI-generated text in parts is contradictory. “If rides I wrote are in there, and also rides AI wrote or will write are in there, then AI was still used, and I was still replaced,” she told the outlet, calling Saber’s statements “ridiculous.”
Footage from the game’s teaser suggests some passenger dialogue and audio could be generated, and the Steam listing for Rideshare “Stimulator” currently does not disclose the use of generative AI. Saber describes the title as an “immersive driving simulation game” in which players manage a rideshare business; the studio says an infinite passenger system requires AI for the experimental mode.
Why this matters for games and AI labor
The exchange highlights a broader tension in the games industry over transparency and labor when studios adopt generative AI for narrative content. Developers and publishers are facing growing pressure to make clear when and how AI is used, and workers are raising concerns about job security and proper disclosure.
- Former lead writer Stella Sacco says she was replaced by ChatGPT mid-development
- Saber’s CEO Matthew Karch denies replacing writers and says only an experimental mode uses AI
- Teaser material and the Steam page offer no clear AI disclosure
- The debate raises questions about labor, transparency, and industry practice
