Going beyond simple keyword matching, a multimodal AI analyzes product images and detailed information together to determine suitability. It provides fine-grained filtering options such as price range, new item status, and specific regions (city/district level), while managing per-account quotas by utilizing multiple accounts simultaneously and distributing IP blocking risks through a proxy pool.

A Web-based management interface allows you to handle job creation, account login status management, execution log review, and result export from a single screen. It sends instant notifications through various channels such as ntfy.sh, Telegram, and Webhooks, and automates repetitive monitoring tasks through Cron-based scheduling.

It can be deployed as a Docker container, allowing for a quick start without complex browser environment configuration. It uses SQLite as the default storage to efficiently manage price fluctuation history and search results, and is released under the MIT license, making it suitable for automation tasks in personal projects or small teams.
