Shown·Partial·ChatGPT agent, Other, Perplexity Comet
AI browser shopping test
ChatGPT agent and Perplexity Comet: DreamHost tested five AI browsers on one Amazon task: research grinder coffee makers under $100, tabulate five, add two to cart.
Perplexity Comet completed the task and stopped at the cart. ChatGPT Atlas also reached checkout but was too slow to be usable.
Overview
How it was set up
Perplexity Comet, ChatGPT Atlas Agent mode, Opera Neon, Dia and Chrome with Gemini, each given the same natural language prompt on Amazon.
Worth knowing
The excerpt is cut off before the Opera Neon, Dia and Chrome results. Testing was one shopping task plus research prompts.
A prompt to start from
Go to [shopping site], research the best [product type] under [price] with [feature], and create a table of the 5 best. Then add two of the best choices to cart with my [city] address selected.
