Teach My Little Sister How To Drive, a free Steam demo that asks players to talk a digital younger sister through driving lessons, has become so popular that its four-person developer says it took out a bank loan to keep the game online.
Success has come with a steep price tag. After player numbers jumped more than twentyfold, the developers behind Teach My Little Sister How To Drive said their AI bill had climbed to more than $1,000 a day. To keep the free demo online, the four-person team said it even turned to a bank loan.
Here's what to know
In an October 7 update, Easy Fox said the surge in attention had made the demo costly to operate, according to Dexerto. The team said, "We are currently spending over $1,000 per day on AI services for the demo."
The game's design drives that expense. Players ride in the passenger seat and talk a digital younger sister through driving, while AI interprets their spoken directions and generates responses on the spot.
Easy Fox said the problem comes from the size of the audience, not from unusually costly individual users. The studio said no single player is especially expensive to support. In its words, player numbers had risen by more than "twentyfold," pushing operating costs high enough that the team borrowed money to keep the demo online.
More background
The update also pointed to a technical problem alongside the financial one. Easy Fox said Google's Gemini model had been its primary AI option, but repeated usage caps forced the team to rely more on an OpenAI backup.

That fallback has created its own issues, the studio said. According to Easy Fox, it has led to long-winded replies, awkward dialogue, and moments when the sister misreads what the player is telling her to do—a serious flaw for a game centered on voice-guided driving lessons.
Easy Fox said it doesn't plan to bill players separately for AI use in the finished game, so those costs will likely be reflected in the overall purchase price.
What's being done?
While interest remains high and players keep logging on, the studio said a bank loan has allowed the demo to stay online.
For the full release, Easy Fox said it still plans to build AI costs into the normal purchase price instead of adding a separate charge. The demo remained available.
Easy Fox explained the situation, saying, "We want to continue operating the demo and would love for more people to enjoy it. However, we are a small team of four, and financial pressure may mean we have to close the demo earlier than expected before the full release."
