✓Genuinely autonomous multi-step browsing — books flights, drafts emails, completes forms
✓Runs inside a real Chromium profile so logged-in sessions just work without extra auth setup
✓Choice of underlying frontier models (Claude, GPT, Gemini, Sonar) avoids vendor lock-in
✓Bundled with Perplexity Pro/Max — no extra subscription if you already pay for Perplexity

✗Agent has access to every logged-in service in the profile — high blast radius if it misfires
✗Full agent capabilities are gated behind the $200/month Perplexity Max tier
✗Per-domain consent prompts and admin controls are still maturing in mid-2026
✗macOS and Windows shipped first; mobile and Linux support lag behind

✓URL bar as chat input reduces 'about this page' friction to a single keystroke
✓Workspace-level conversation threads turn a 20-tab research session into one chat history
✓Skills system rewards curation — a personal library of named workflows replaces extension sprawl
✓Built on Chromium so web compatibility is identical to Chrome and Edge

✗Skills require curation — there is a learning curve before the library starts saving time
✗Autonomous agent capabilities are narrower than Perplexity Comet's by design
✗No MCP support announced as of mid-2026 — can't plug in custom tool servers yet
✗macOS and Windows first; mobile companion apps still in development
