Automate email unsubscribes, calendar events, and shopping in a browser
A hands-on test of Comet's browser agent handling unsubscribes, calendar events, shopping, LinkedIn posts, research and an Instacart lasagna cart, with mixed results on complex workflows.

- What they did
- The Reddit post summarizes a hands-on Comet browser demo where the agent was connected to live sites like Gmail, Google Calendar, shopping sites, LinkedIn, Instacart, Reddit, and research tabs. It handled click-and-fill tasks such as unsubscribing some promotional emails, creating four Taco Tuesday events, comparing Walmart and Target prices, building an Instacart lasagna cart, and drafting a LinkedIn post, with human confirmation required for sensitive actions and help needed when flows got tricky.
- How it went
- It worked well on structured browser chores and could run tasks across tabs, but stalled on harder unsubscribe flows, struggled with complex apps like Photopea, and hit login, region, or site-security friction. The post’s concrete wins include four calendar events created and old non-lasagna cart items removed before checkout.
- Worth knowing
- The main catch is privacy and reliability: the post recommends using a separate Comet profile and reviewing its default data-retention settings before giving it account access.
Try it yourself with Perplexity Comet
In my browser, go through my recent promotional emails in [Gmail or other inbox], list the senders you propose to unsubscribe from, and wait for my okay. After I approve, unsubscribe from them and give me a summary of which ones worked and which failed. Do not unsubscribe, delete anything, or buy anything without showing me what you are about to do first.
