What is Prophet?
Prophet is an open-source, AI-powered Chrome extension that integrates Anthropic's Claude AI models directly into your browser's side panel. It supports Claude Haiku 4.5, Sonnet 4.6, and Opus 4.6 with real-time streaming responses, browser automation via 18 built-in tools, and pay-per-use pricing starting from a free tier. Unlike screenshot-based browser AI tools, Prophet uses the accessibility tree for faster, more deterministic interactions with web pages. The full source code is available on GitHub.
