Tabbit (https://www.tabbit.ai/) is a browser with an AI chatbot, based on Chromium, available for macOS and Windows.

Integrated chatbot with the possibility of selecting several models to compare (up to 5, “Multi-model” mode) among about thirty models (GPT, Claude, Gemini, DeepSeek, Qwen, GLM, Kimi, MiniMax, LongCat…).

The “Mode Agent” navigates and executes multi-step tasks based on a natural language instruction. Can generate images, presentations, websites, and pdf, word, or excel files.

A “Deep Research” mode with reporting is proposed.

Skills system: reusable, self-created or community-shared automation scripts.

The “@” button allows you to drag an open tab, screenshot, bookmark, or local file as context.

Tabs are automatically grouped by topic or project, with search in open tabs.

Note: the publisher (Lumina Lab, based in Singapore) indicates that history and exchanges remain encrypted locally. On the other hand, instructions and documents sent to a model pass through the servers of the chosen provider.

Free browser with free access to a selection of models (DeepSeek-V4.1-Flash, Gemini-3.8-Flash, GLM-5.3, Qwen3.8-Max, MiniMax-M3, Kimi-K2.6…).
Free quota of basic interactions not specified but x10 quota by setting Tabbit as the default browser.
