04 Questions

Good to know.

Everything you might wonder before adding Rexa to your browser.

What exactly is Rexa Pilot?

Rexa is an AI sidebar for Chrome. It docks to the side of any page and lets you chat with that page, your own documents and the live web — plus reply, summarize, translate, take voice calls and run agent tasks, all without leaving the tab you're in.

Which sites does it work on?

The sidebar and most tools work on every website. In-page features like instant replies are tuned for Gmail, Slack, LinkedIn, Outlook, X and Reddit, while video summaries support YouTube, TikTok, Instagram, X and Facebook.

Do I need to pay or add a credit card?

No. You sign in with Google and start using Rexa for free — no credit card required.

Can it really fill forms and click for me?

Yes. The do-it-for-me agent perceives the live page and performs actions in your real, logged-in tab — navigating, typing and selecting. It narrates each step and asks you to confirm before anything important, like submitting or paying.

How does it answer from my own documents?

Upload files into your Knowledge Base and Rexa builds a private, searchable index. When you ask a question it retrieves the most relevant passages and answers with inline citations back to the source file and page.

What languages are supported?

More than 50. Choose your language once in settings and every response — chat, replies, summaries — comes back in it.

Free to start
