It includes a Visual Selector tool for easier element targeting. - **AI Integration**: Supports connection to LLMs (via LiteLLM) to provide plain-language change summaries and intelligent alert filtering based on natural language rules. - **Interactive Browser Steps**: Can perform actions like logging into websites or filling out forms before detecting changes. - **Notifications**: Integrates with the Apprise library to support a wide range of notification services, including Discord, Slack, Telegram, Email, and Webhooks. - **Advanced Monitoring**: Capable of tracking changes in PDF files and JSON API responses. - **Scheduling**: Offers flexible re-check schedules, including timezone support and business-hour limits. The tool can be deployed via Docker, Python Pip, or installed on Windows and Raspberry Pi. It also provides a Chrome extension for quickly adding pages to the monitor and a REST API for programmatic management.
