Comet puts an assistant in your browser. Put one in a cloud browser that works on a schedule

Description and use

Perplexity’s Comet browser with an AI assistant can be run on a schedule in a persistent Burrowbox cloud browser, keeping user logins intact.

Problem

Need a browser‑based AI assistant that can run tasks on a schedule while staying signed in to accounts.

Outcome

By combining Burrowbox’s persistent browser with scheduled jobs and event webhooks, the user can run the Comet assistant on a recurring schedule, automatically navigate to a dashboard, and receive notifications when the task completes, all without manual intervention.

Workflow

• Create a Burrowbox machine with "browser":"full" to preserve login cookies.
• Schedule a job via Burrowbox API to wake the machine and navigate to a URL on weekdays at 07:00 UTC.
• Register an event webhook with Burrowbox to receive run.succeeded and run.failed events.
• Set up an Express server that verifies the Burrowbox signature, responds 200, then processes the event to run the assistant and turn the machine off.

Evidence

Perplexity launched Comet on July 9, 2025. It's a web browser with Perplexity's search built in and an assistant in a sidebar.

A Burrowbox machine has one persistent browser. Sign in once ... and its cookies survive stops and restarts.

The scheduled job starts the machine if it's off and opens the dashboard in its signed‑in browser.

Register an event webhook. Burrowbox signs each event and retries failed deliveries with backoff.
