Why people leave Comet

Comet is free and capable, so people rarely leave over price. The common reasons, based on the published facts:

  • Security. Brave disclosed an indirect prompt injection in Comet on August 20, 2025 that let a hidden Reddit comment steal a user's email and login code, and said Perplexity's fix was incomplete. A second disclosure on October 21, 2025 used near invisible text in screenshots. In December 2025 Gartner advised companies to block AI browsers, naming Comet.
  • Not wanting another browser. Gemini in Chrome and Claude in Chrome add AI without switching.
  • Model choice. Perplexity picks the model behind Comet Assistant, and its advanced Assistant models sit on Max at $167 per month billed annually.
  • Output. Comet answers and acts in tabs. Agents like ChatGPT Work, Genspark and Manus deliver files.

Security checklist for any AI browser

Whatever you pick, the risk Brave found in Comet exists across the category. Block agent access to banking, health and work email sites. Use separate profiles for agent work. Approve each action on signed in sites. Keep prompts specific. Watch the agent's tab while it works.

Moving your data out of Comet

Comet is Chromium based, so leaving is simple. Export bookmarks to an HTML file and import them into Chrome, Dia or Neon. Passwords can be exported and imported the same way; delete any exported password file afterward. Perplexity's help center explains self serve deletion of local browsing data, threads, Spaces and files, and a 30 day window when you delete your Perplexity account.

How we picked

We ranked alternatives by how well each one solves a specific reason to leave Comet, using vendor pricing pages, help centers, app store listings and published security research as of October 2026. We do not claim to have used these products. Compare Comet vs Dia or see the best AI browsers.
