Question 1

What is an agentic browser?

Accepted Answer

An agentic browser uses AI to interpret your goal and take actions on the web—clicking, typing, navigating—until the task is done, not just answering questions in a sidebar.

Question 2

How is Tabbit different from Perplexity Comet in this comparison?

Accepted Answer

Both offer agentic browsing. Tabbit emphasizes parallel tab-group agents, @ context from live tabs and files, and Skills for repeatable workflows—all free on Windows and Mac.

Question 3

Is ChatGPT Atlas better for agentic tasks?

Accepted Answer

Atlas excels if you live in ChatGPT and pay for Plus. Tabbit is stronger when you want a standalone free browser with agent execution and vertical tab workspaces.

Question 4

Do I need Browser Use or Browserbase instead?

Accepted Answer

Those are for engineers building custom agents with APIs. This comparison targets browsers you download and use—Tabbit fills that role without Python or session hosting.

Question 5

Which agentic browser is best for research?

Accepted Answer

Fellou and Comet focus on research. Tabbit matches them with deep multi-tab research plus @ context and structured deliverables—free.

Question 6

Are agentic browsers safe?

Accepted Answer

Granting an agent click access carries risk on untrusted sites. Tabbit runs agents in separate tab groups so you can review steps; avoid sensitive credentials on unknown pages.

Question 7

Can I compare agentic browsers on Windows?

Accepted Answer

Yes. Tabbit, Comet, Fellou, Edge, and Browser Use (dev) support Windows. Dia and Atlas remain more Mac-centric today.

Question 8

Is Tabbit really free in this comparison?

Accepted Answer

Yes—Tabbit has no invite code and includes flagship models at no cost during public beta on Windows and macOS.
