FAQ
Open AI ブラウザの質問
Is “open ai browser” the same as ChatGPT Atlas?
Yes for most searches. OpenAI’s browser product is ChatGPT Atlas. Typing with or without a space usually lands on the same intent.
Does Tabbit include OpenAI / GPT models?
Yes. Tabbit ships GPT models alongside Claude, Gemini, DeepSeek, Qwen, and more—so you are not limited to Atlas’s ChatGPT-only stack.
Is ChatGPT Atlas the same as Operator?
No. Atlas is a consumer browser. Operator is a separate agent product. Tabbit combines browsing and Agent Mode in one desktop app.
Open AI browser for Windows—does Tabbit work?
Tabbit supports Windows 11 and macOS with the same AI features. Atlas Windows availability varies by region and rollout.
Is Tabbit free compared to Atlas?
Tabbit is in free public beta with Agent, multi-model chat, and smart tabs included. Atlas is free to start but advanced usage follows ChatGPT subscription limits.
Should I uninstall Chrome to try Tabbit?
No. Import bookmarks, passwords, and extensions from Chrome, Edge, or Safari—trial without a painful migration.
When is Atlas enough?
If you only want OpenAI-branded ChatGPT beside your tabs and rarely automate multi-step work, Atlas is fine. Tabbit wins when you need execution, models, and tab control together.
Where do I download Tabbit?
Use the buttons on this page—they open the official site for your region (tabbitbrowser.com international, tabbit-ai.com China) with no invite code.
