Comet Browser
Most “comet browser” searches mix three jobs: understand the product, compare alternatives, and sanity-check pricing. Start with the split view, then pick a path below.
What Comet optimizes for
Perplexity Comet is an AI-forward browser: a built-in assistant aware of pages and sessions, task shortcuts, and a subscription ladder that unlocks deeper models and automation.
What Tabbit optimizes for
Tabbit is an agentic AI browser built for open model choice, human approvals before autonomous actions, and reusable Skills—free to download on macOS and Windows.

Why people type “comet browser” into Google
Some visitors want the official story: what ships in the installer, which platforms exist, and how tightly the browser couples to Perplexity accounts.
Others already use Comet but are shopping for a comet browser alternative—usually because they want broader model choice, clearer automation guardrails, or a pricing posture that fits teams.
This page keeps both camps honest: a neutral framing of Comet’s shape, then a transparent view of where Tabbit overlaps and where it diverges.
Product context
Comet browser in plain language
Comet positions itself as a personal AI assistant embedded in browsing: summarization, cross-tab synthesis, and delegated tasks are headline behaviors rather than optional extensions.
Advanced capabilities often map to paid tiers—typical for frontier-model access—so “free comet browser” and “best models” questions should be read against Perplexity’s own pricing pages, which change over time.
Feature names, tiers, and availability can change. Always verify on Perplexity’s official pages before purchasing.
Fit check

You need approval-first automation
Agents should explain the plan before touching authenticated pages. Tabbit emphasizes supervised execution instead of silent autopilot.
You encode repeatables as Skills
