Does it deserve #10?
Is Comet worth it?
For most people, yes. Comet scores 8.2/10 and ranks #10 in AI Assistants. It's best for researchers and heavy web users who want AI help beside every tab. Skip it if you don't want an AI company reading the pages you visit. Price: Free on every platform; Perplexity Pro ($20 a month) and Max raise the limits.
The verdict
Comet is Perplexity's web browser, with an AI helper beside every tab. It can sum up a page or compare products across sites. It can even work through a multi-step task while you browse. Bigger jobs go to Perplexity Computer. It's free on Mac, Windows, iPhone and Android, and your sessions sync between them. The trade-off is privacy. The helper has to read your pages, and a synced account lets Perplexity record your history.
