Comet Browser

Genuinely useful as a second browser for research-heavy sessions. Do not put it on the critical path for anything regulated.

Consilix rank 7/10

What it is

Perplexity's AI-native web browser. Chromium-based, with an assistant pane embedded in every page that can summarise, extract, cross-reference across tabs, and act agentically (book a flight, fill a form, order groceries, triage an inbox). As of 2026 it runs on iOS, Android, macOS and Windows; the free tier is fully functional. The agent is powered by Sonnet 4.6 for Pro users and Opus 4.6 for Max.

Weaknesses

Agentic commerce is on shaky legal ground; Amazon won a preliminary injunction in 2026 blocking Comet from accessing password-protected Amazon pages. Privacy posture is less clear than Safari or Firefox; treat sensitive sessions with care. Still a young browser, occasional rough edges on extension compatibility and password manager handoff.

Pricing

Free on all platforms. Pro users get Sonnet 4.6 as the default agent model; Max users get Opus 4.6.
