Prophet is a Chrome extension that brings Claude AI into the browser sidebar and adds web automation capabilities on top. It is not just a simple chat box: through a custom agent loop, it lets Claude observe web pages, analyze tasks, call tools, and repeat actions. It is well suited for tasks within the current browser session, such as clicking, filling forms, navigating pages, and reading content.
Its core technical approach uses the accessibility tree rather than screenshots or raw HTML. This helps it focus on interactive elements such as buttons, links, and input fields, assign internal UIDs to those elements, and then use the Chrome DevTools Protocol to perform actions like clicking, typing, scrolling, waiting, and managing tabs. Claude model options include Haiku 4.5, Sonnet 4.6, and Opus 4.6, covering everything from simple tasks to more complex reasoning. Each conversation allows up to 10 tool calls, which helps control risk but also limits longer automation workflows.
The free plan includes $0.20 in credits, equivalent to roughly 50 Haiku messages, and does not require a credit card. Paid tiers include Pro at $9.99, Premium at $29.99, and Ultra at $59.99, each offering different API credit amounts and bonus ratios. Users can also make a one-time purchase of $10 in credits. Its credit system is billed based on Anthropic API usage, with an additional 20% platform fee. For occasional use, this may be more flexible than a fixed monthly subscription.
The main advantages are that browser tools run client-side and can use the user’s already logged-in sessions; according to the official description, page content stays on the local machine and the backend does not inspect browsing content; and the accessibility-tree approach uses fewer tokens than screenshots while offering more deterministic element targeting. The drawbacks are that it still depends on the Anthropic API and the Chrome extension environment, Chinese-language support is not specified, and complex tasks may be constrained by the 10-tool-call limit. There is also an inconsistency in the copy regarding whether there are 18 or 19 tools.
Prophet is suitable for researchers, operations teams, developers, administrative staff, and other users who frequently search for information on web pages, fill out forms, or operate web-based dashboards. For users in China, the source text does not specify domestic network connectivity, Stripe payment availability, or RMB payment support, so china_access can only be considered unknown. If stable access is not possible, alternatives may include Claude in Chrome, Playwright MCP, or local/China-developed AI browser automation tools.
