- +Consumer-friendly browser agent that books, fills, and completes web tasks autonomously
- +API lets developers embed browser-agent capabilities in their own products
- +Chrome extension keeps the agent close to where users already work
- −Reliability varies widely across websites — 5–15% error rate typical
- −Best for low-stakes workflows; not for production payments or critical ops
- −Voice quality + multimodal features still maturing
