Mochii AI

Mochii AI is a unified interface for working with multiple leading large language models, including GPT-4o, Claude 4.0, and Gemini 2.5. Its primary purpose is to let users compare and leverage different AI systems in one place, while also enabling the creation of custom AI characters and knowledge-based chatbots. Mochii is available as both a web application and a free browser extension for convenient access during everyday browsing and research tasks.

Mochii AI allows users to spin up tailored AI personas with configurable behavior, tone, and expertise, making it easier to standardize responses for specific workflows or teams. Users can connect their own documents, notes, or knowledge bases so chatbots can answer questions grounded in their proprietary content. The browser extension supports on-page interactions such as summarizing articles, drafting responses, or explaining complex material directly where the user is working. Centralized access to multiple models enables side-by-side comparisons, model switching for different tasks, and redundancy when one provider is slow or unavailable.
