Op ninja (official name OnePage Ninja, website https://www.onepage.ninja/）是一款面向求职场景的AI简历工具。根据现有资料，其核心定位有两点：一是借助AI辅助生成简历，二是内置投递跟踪功能，用于了解职位申请的状态。
In terms of purpose, this tool mainly serves job seekers' needs for creating resumes and managing job application progress. It emphasizes a "one-page" resume, that is, condensing content onto a single page so that recruiters can quickly scan it.
In terms of main capabilities, the information explicitly mentions two items: AI resume generation and application status tracking. Users can use AI to organize and write resume content, and through the built-in tracking feature record and view the submission progress for each position, thereby gaining a clearer grasp of the job search process.
In terms of usage, the available information does not provide specific operating steps, registration process, or interface instructions, and is not yet available.
In terms of applicable scenarios, it is suitable for job seekers who need to quickly produce concise resumes, apply to multiple positions at the same time, and want to track application statuses in a unified way.
In terms of limitations, information regarding its AI model, template styles, export formats, whether it charges and pricing, and supported platforms and languages is not provided in the available information and cannot be confirmed.
