Life Admin & HomeDone with Perplexity Comet Oct 10, 2025
Complete an online course assignment in the browser
Perplexity Comet was prompted to complete a Coursera web design assignment and appeared to finish it in a short clip; the CEO told people not to do this.
- What They Did
- A developer used Perplexity's agentic Comet browser on a Coursera course page. The only prompt shown was a short instruction to complete the assignment. Comet read the page and worked through what looked like a 45-minute web design assignment by itself. The developer posted a screen clip on X and tagged Perplexity and its CEO.
- How It Went
- The 16-second clip shows Comet apparently finishing the whole assignment. The article doesn't say whether the work was graded or correct. CEO Aravind Srinivas replied publicly: "Absolutely don't do this."
- Worth Knowing
- Fortune cites security audits that found Comet can follow hidden instructions on web pages and complete purchases on fake sites without human checks, so supervise it closely.
