What makes it
A ChatGPT browser, not just ChatGPT in a browser
It executes, not just answers
Agent Mode opens its own tab lane to fill forms, pull data, and run research loops across websites without you babysitting every click.
Switch models on the fly
Start with GPT, then hand off to Claude, Gemini, DeepSeek or Qwen when another model fits the task better.

How it works
From question to finished work in three steps
1
Ask from the Omnibox
Type a question, URL, or task. GPT reads the page you are on—no copy-paste relay between tabs.
2
@ what you see
Reference open tabs, screenshots, PDFs, or saved collections as context. ChatGPT answers with your real workflow in view.
3
Let Agent finish it
When chat is not enough, Agent runs forms, research, and data pulls in an isolated tab group—parallel to your work.
Models
ChatGPT plus the models you already trust
GPT
Draft, code, and analyze with OpenAI models inside Tabbit.
Claude
Long-context reasoning alongside GPT—one click away.
Gemini
Multimodal search and synthesis without leaving the browser.
DeepSeek & Qwen
Strong regional models when GPT is not the best fit.
Use cases
What people do with a ChatGPT browser
Research without tab chaos
GPT summarizes papers and articles; Agent collects sources into a grouped workspace you can revisit later.
Write with page context
@ the brief, competitor page, or analytics tab—ChatGPT drafts in your tone with facts from what is open.
Automate the boring clicks
File expenses, fill forms, or pull structured data. Agent handles the loops; you approve the outcome.

Extensions overlay chat on top of a normal browser. Tabbit rebuilds browsing around AI—vertical tabs, @ context, Skills shortcuts, and Agent lanes that run multi-step work without you babysitting every click.
