Use an AI browser safely
AI browsers that act for you can be misled by hidden instructions on web pages, a problem called prompt injection. In 2025, researchers at Brave and LayerX reported such issues in Comet. Good habits keep you in control:
- Review before it acts. Read what the assistant plans to do before purchases, sending emails or submitting forms.
- Keep sensitive accounts separate. Avoid letting the assistant act while you’re signed in to banking or work admin sites.
- Watch for surprises. If it suddenly visits unexpected sites or asks for codes or passwords, stop the task.
- Stay updated. Install Comet updates promptly; security fixes arrive through updates.
- Start read-only. Use summaries and comparisons first, and give it actions once you’re comfortable.
FAQ
Comet browser questions
Is Comet free?
Yes. Comet has been free for everyone since October 2025. Comet Plus, which adds premium publisher content, costs $5 a month or is included with Perplexity Pro and Max.
What devices does Comet run on?
Windows 10 or later, macOS Big Sur or later, Android 12 or later and iOS 18 or later. Download it from perplexity.ai/comet or the official app stores.
Is Comet based on Chrome?
Comet is built on Chromium’s Blink engine, the same open-source engine behind Google Chrome, so websites work as you’d expect and many Chrome extensions are compatible.
What can the Comet Assistant do?
It can read the page you’re on, summarise and compare information across tabs, draft emails, help with your schedule, compare products and carry out multi-step tasks on websites, with you reviewing important actions.
Is Comet the same as the Perplexity app?
No. The Perplexity app is for asking questions. Comet is a full web browser with Perplexity’s assistant built in. Many people use both.
Is Comet safe to use?
Use it with care. In 2025, security researchers at Brave and LayerX reported prompt-injection issues, where hidden instructions on a web page could mislead the AI assistant. Keep Comet updated, review actions before they happen, and avoid letting the assistant act on sensitive accounts.
Can I import from Chrome?
Like most Chromium-based browsers, Comet supports bringing over data such as bookmarks from your current browser. Look for the import option during setup or in Comet’s settings.
