Developers often juggle multiple AI tabs, leading to 'AI Fatigue' and workflow friction. Noi, an open-source browser by developer lencx, addresses this by unifying AI workflows. It is the creator of the popular ChatGPT desktop application.

Its 'Noi Ask' feature allows users to send a single prompt to multiple AI models simultaneously, such as ChatGPT and Claude, for instant cross-referencing. The tool includes a built-in prompt library and 'Cookie Isolation,' enabling separate logins for personal and work accounts without using Incognito modes. By treating LLMs as utilities rather than just websites, Noi streamlines the development process.

It is available for macOS, Windows, and Linux via GitHub, offering a local-first, privacy-focused alternative to general-purpose browsers like Chrome.
