Tabbit is an AI-native desktop browser for macOS and Windows that turns browsing into agentic work.

Comet is Perplexity's AI-powered browser. It puts an assistant inside the browsing experience so you can ask questions about what is on screen, summarize pages, draft emails, build small artifacts, and delegate multi-step tasks across the web.
The assistant understands the page you are on, so you can ask follow-up questions and get answers grounded in what you are reading.
Delegate tasks like drafting replies, creating study plans, or building a simple website, with the assistant taking actions for you.
Comet runs on Mac, Windows, iOS, and Android, so your browsing and your assistant follow you across devices.
Perplexity's answer engine is built in, so research and web search stay inside the browser instead of a separate tab.

Tabbit is an AI-native desktop browser for macOS and Windows that turns browsing into agentic work. It reads your open tabs, PDFs, bookmarks, screenshots, highlights, and local files as context, then chats with them, runs multi-step web tasks with Agent, and executes ready-made Skills for research, GitHub, email, and media.
Drop in a tab, a file, a screenshot, or a highlighted element and the agent reads, plans, and runs on it — no copy-pasting between apps.
Automate multi-step tasks on real websites, including deep research, form filling, and data collection, with several agents working in parallel.
Ready-made Skills for the sites you actually use — video triage, podcast highlight extraction, PDF table export, PR explanations, subscription audits — plus a builder for your own.
Switch between a broad menu of leading models from multiple vendors, with your chosen model always shown at the top of the chat.
