Overview
- Amazon confirmed it sent a cease-and-desist telling Perplexity to stop Comet from transacting on Amazon, arguing third-party agents must operate openly and respect a platform’s decision to participate.
- The company’s letter, described in multiple reports, accuses Perplexity of computer fraud, terms-of-service violations, disguising automated activity as a Chrome browser, and degrading the customer experience with privacy risks.
- Amazon previously warned Perplexity in November 2024; by August 2025 it says Comet was reactivated in a way that bypassed blocks, prompting the latest legal demand.
- Perplexity denies wrongdoing, says Comet acts on users’ behalf with credentials stored locally, and argues Amazon is protecting ad revenue rather than customer experience.
- The clash spotlights unresolved rules for agentic browsers as both firms build their own shopping assistants, and some outlets reported a lawsuit filing that has not been widely corroborated.
