Extensions can only see the active viewport
Third-party plugins miss background tabs, local PDF files, your research history, and complex dynamically loaded web scripts.

THE EXTENSION PROBLEM
Why traditional browsers and AI add-ons feel fragmented
Adding a chatbot extension to an old browser creates friction. Isolated sandboxes, frequent permission errors, and single-model restrictions make daily work frustrating.
02
Endless copying and pasting breaks your focus
Every question requires selecting text, copying URLs, hopping across windows, and re-explaining context from scratch.
03
Locked into a single proprietary AI model
Most AI browsers force you to use their own proprietary assistant or a single vendor, leaving you stranded when you need specialized reasoning.

FREQUENTLY ASKED QUESTIONS
Everything you need to know about AI chat in Tabbit
What is a browser with AI chat, and how is it different from ChatGPT?+
A browser with AI chat has conversational intelligence built directly into the web browsing engine. Unlike ChatGPT in a separate browser tab, Tabbit can directly read, interpret, and interact with the webpages, PDFs, and tab groups you currently have open, eliminating the need to copy and paste text back and forth.
Is Tabbit Browser with AI chat free to download and use?+
Yes. Tabbit Browser is free to download during its public beta for macOS and Windows. You get built-in access to AI page summarization, Omnibox conversations, and multi-model browsing without paying an upfront subscription.
Can I chat with any open webpage, PDF, or document?+
Absolutely. Whenever you open a webpage or PDF in Tabbit, click the Chat icon or type @ in the Omnibox. You can ask for quick summaries, query specific sections, extract tabular data, or translate technical jargon instantly.
Which AI models can I choose from when chatting?+
Tabbit supports a comprehensive roster of frontier models including GPT-5.4, GPT-5.2, Claude 3.5 Sonnet, Claude Opus, Gemini 3.1 Pro, DeepSeek V3/R1, Kimi, Qwen, and GLM. You can switch models with a single click or run them side-by-side.
How does Tabbit’s AI chat compare to Opera Aria and Brave Leo?+
Opera Aria and Brave Leo lock you into their own proprietary or limited model ecosystems and only provide basic sidebar text chat. Tabbit offers full multi-model freedom (GPT, Claude, Gemini, DeepSeek), simultaneous parallel comparison across multiple LLMs, and an autonomous Agent Mode that can perform real actions on web pages.
Is my browsing data and private information safe?+
Yes. Tabbit respects user privacy and treats your security as paramount. Your browsing activity is never used for training third-party public models without permission, and web context is only transmitted when you explicitly invoke an AI chat prompt.
What operating systems does Tabbit Browser support?+
Tabbit is available as a native high-performance application for macOS (both Apple Silicon M-series and Intel chips) and Windows 10/11 (64-bit). Linux and mobile support are actively in development.
Can the AI chat actually perform actions on websites for me?+
Yes. By activating Agent Mode, Tabbit can take natural language instructions and carry out browser tasks such as filling out online forms, inputting data into Google Sheets, or collecting structured information across multiple search results.
