San Francisco-based AI company Use.ai said on October 1, 2026, that it had surpassed one million monthly active users less than a year after launch. Its workspace provides access to more than 10 AI models, including GPT, Claude, Gemini, Grok and DeepSeek. Users can switch models within a conversation while retaining its context, according to the company.
Use.ai offers a free Answer Engine based on open-weight models that it configures and optimises, with more advanced models available through a paid subscription. Users can draw on different models as a research, writing or planning task develops. The platform is designed to reduce the need to move between separate services and re-enter conversations or preferences.
Co-founder Ihor Herasymov previously worked in mergers and acquisitions and technology investment. According to the company, he went on to launch seven businesses and grew a technology company to more than 100 employees and $3 million in annual revenue within two years. His experience using multiple AI platforms drew his attention to how difficult it was to carry conversation histories and personal preferences from one service to another. “I don’t want to lose that context whenever a better model appears,” Herasymov said, describing the idea behind Use.ai as one account that keeps context available across models.
In a company survey of more than 5,000 users, 42% said they switched models for better quality or deeper reasoning, while 36.5% said their choice depended on the task. A separate survey of more than 30,000 users found that 54% were either using AI for the first time or had tried it only a few times. Use.ai is developing automatic routing to select a model suited to each task, reducing the need for users to compare models themselves. The company did not disclose how respondents were recruited or how representative the surveys were of its wider user base.
Use.ai’s next goal is to extend the platform from answering questions to carrying out tasks. With a user’s permission, a proposed personal assistant could connect to calendars and other apps to help arrange appointments or prepare purchases based on the user’s schedule and preferences. For example, the company envisages an assistant checking salon availability, making a booking and setting a reminder. It also describes a shopping assistant that could compare running shoes and prices, then seek the user’s confirmation before making a purchase. These are examples of planned capabilities, rather than features the company says are available today.
“Our users shouldn’t need to follow model releases, compare benchmarks or decide which model is best for every task,” Herasymov said. Use.ai plans to build on model switching and shared context by coordinating AI models and connected apps to complete more of a user’s request.
