In their own words
Comet
Comet is Perplexity’s AI browser, with an assistant built into browsing. The assistant can answer questions about open tabs, search the web and interact with websites on the user’s behalf. Examples include summarizing or explaining content, comparing tabs, drafting emails, scheduling meetings and making purchases. Perplexity is the default search engine, and Comet uses Chromium. It is free to download at free for Android, iOS, macOS and Windows. Comet supports most Chrome extensions, though users must install and configure them again because extension data does not transfer from Chrome. The browser stores URLs, searches, cookies, open tabs and site permissions locally. Website credentials are kept in the device’s secure vault, not on Perplexity’s servers. Privacy settings allow deletion of browsing and search history, cookies and cached data. However, some queries may involve sending page context, including text or email, to Perplexity’s servers. Email or schedule tasks may require opting in to Perplexity Connector access; those permissions can later be changed or revoked. Comet says users can stop the agent and should review actions before confirming them.
Muse
Muse is a personal AI agent for handling tasks and projects and turning longer-term goals into action plans. It can keep working after the app closes, then return when something changes or it needs approval. The agent can browse websites, fill forms, complete transactions, and create documents, PDFs, web pages, and interactive artifacts. Its small-business page lists connections to services including Asana, Canva, Dropbox, Figma, QuickBooks, Notion, Shopify, Slack, Stripe, Zoom, and social platforms. Muse requests approval for sensitive actions such as sending email or making purchases, and displays an audit trail of activity and planned actions. Users can choose connected apps and access levels, disconnect services, opt out of model training, or ask Muse to forget specific information. It runs on a dedicated cloud virtual machine, with a separate Sentinel controlling connector actions and network access. The free plan has a periodically refreshed usage limit. Power costs $20 a month and Maximum costs $100 a month. Subscriptions are in limited testing and not available everywhere; Muse for Small Business is available to people in the US and Canada who are 18 and over.
