Comet is Perplexity’s browser, locked to Perplexity’s model. Egg is BYOK by default, with skills, an agent firewall, and a workspace layer Comet doesn’t ship.

Comet routes everything through Perplexity. Egg goes direct to whichever provider you brought a key for — or to Ollama on your hardware. The model isn’t the product; the browser is.
Use Anthropic, OpenAI, Google, OpenRouter, or local Ollama. Mix per agent, per task. No proxy, no relay — the daemon calls your provider directly.
The agent runs skill bundles — web research, Google Workspace, code execution, media processing, local files, and custom folders you write yourself.
Filesystem-backed projects, knowledge compilation, contacts, monitors, publish. Comet’s Spaces are tab-grouping. Egg’s workspaces are a system.
Always-on tracker blocking, parameter stripping, prefetch suppression. Comet inherits Chromium defaults and routes inference through Perplexity’s cloud.
Approval prompts, per-service rules, every tool call logged. Comet doesn’t expose this surface area.
If you’re already a Perplexity Pro user, Comet’s search-first UX is tightly integrated with their indexes and citations. Egg is more general-purpose.
