Tabbit

Bottom line: Tabbit looks worth trying as a browser with a built-in multi-model AI workspace, not yet as a fully proven replacement for a mainstream browser. The evidence supports its core positioning: multiple models in one interface, page-aware chat, and basic material aggregation. But evidence is still limited on long-term reliability, enterprise controls, and whether current free access will remain stable.

In practice, it is better understood as a browser plus an AI aggregation layer plus a lightweight research organizer. It is not a model training platform, and it is not a fully autonomous agent that can reliably execute complex business workflows end to end. Zhihu trial posts describe citing a single page, whole tab groups, local Word/PDF/Excel files, and screenshot regions as context, alongside model switching and comparison. That points to research, synthesis, and first-draft work more than office-suite replacement or RPA.

Adoption friction appears low. Several X posts and the official account say users can register, log in, set it as the default browser, and access multiple models or claim Pro.
