ChatGPT extension
Fast to install, but context is limited to selections and you still juggle tabs manually.
Built-in GPT · Agent Mode · Free on Mac & Windows
AI Browser ChatGPT
Tabbit puts ChatGPT inside a real AI browser — not just a sidebar. Ask about any page, switch to Claude or Gemini, and let Agent Mode finish multi-step work in its own tab lane while you keep browsing.
Pick your path
Three ways to get ChatGPT in a browser
ChatGPT Atlas
Native ChatGPT sidebar and smart search — macOS-first, OpenAI models only.
Tabbit Browser
GPT built in, plus Agent execution, model switching, and vertical workspaces on Mac & Windows.
How it works
ChatGPT workflows that actually finish
- 1
Ask from the Omnibox
Type a URL, a question, or a 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
Hand off to Agent Mode
When chat is not enough, Agent runs forms, research, and data pulls in an isolated tab group — parallel to your work.
GPT and beyond
ChatGPT plus the models you already trust
GPT-5.x
Draft, code, and analyze with OpenAI models inside Tabbit.
Claude Sonnet / Opus
Long-context reasoning alongside GPT — one click away.
Gemini 3.1 Pro
Multimodal search and synthesis without leaving the browser.
DeepSeek & Qwen
Strong regional models when GPT is not the best fit.
Skills shortcuts
Save prompts and automations — type / to rerun ChatGPT workflows.
Agent lanes
Turn GPT plans into executed steps across real websites.

FAQ
AI Browser ChatGPT — common questions
Does ChatGPT have an AI browser?
Yes. OpenAI launched ChatGPT Atlas — a Chromium browser with ChatGPT built into a sidebar. Tabbit is another AI browser with GPT access, plus Agent Mode, multi-model switching, and macOS + Windows support in one free download.
What is the new AI browser by ChatGPT?
ChatGPT Atlas is OpenAI’s AI browser: browse the web with ChatGPT beside every page for summaries, answers, and light automation. Tabbit goes further with executable Agent tasks, vertical tab workspaces, and Claude or Gemini alongside GPT.
Is the ChatGPT browser free?
ChatGPT Atlas has a free tier; advanced models may require ChatGPT Plus. Tabbit’s public beta is free on macOS and Windows with GPT, Agent Mode, and tab tools included — no invite code.
What is another AI browser like ChatGPT?
Tabbit is a strong ChatGPT-style AI browser: built-in GPT, page-aware chat, and autonomous Agent runs. Unlike Atlas-only stacks, you can switch models and keep research in organized tab groups.
Can I use GPT inside Tabbit without a separate extension?
Yes. Tabbit is an AI-native browser — GPT lives in the Omnibox and side panel, not as a bolt-on extension. Type a question, @-reference what you see, or launch Agent Mode from the same input.
Is Tabbit better than ChatGPT Atlas on Windows?
If you need Windows today, Tabbit ships the full AI browser stack on macOS and Windows. Atlas availability varies by region; Tabbit also adds Agent tab groups and non-OpenAI models in one app.
Do I need ChatGPT Plus for Tabbit?
No separate Plus subscription is required to start with Tabbit. The international edition includes access to top models during the free public beta; check tabbitbrowser.com for current model lineup.
How is Tabbit different from a ChatGPT Chrome extension?
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.
