Colleague AI is a Chrome extension published by HENSUN INNOVATION LLC and aimed squarely at teachers rather than students. Instead of juggling separate AI chatbots and document tools, educators open the extension from their browser and work on the tasks that consume their planning time: finding and adapting lesson plans, generating classroom activities and professional-development ideas, working through math problems, and giving feedback on student assignments.
The extension leans on practical classroom utilities. You can pull a lesson plan from a library of customizable templates and adjust it to your grade level, run a math problem through a step-by-step solver you can use to check answers before class, scan printed worksheets into editable text, translate teaching material between more than 100 languages for multilingual classrooms, and generate quick replies to parent or staff emails. Custom prompts let you save recurring instructions so the same style of output comes back each time.
Colleague AI is distributed through the Chrome Web Store, where it reports around 2,000 users and lists a developer with a clean policy record. Because it’s a browser extension, setup is a single install — there is no separate dashboard to learn. Its interface ships in 13 languages, which fits its multilingual-classroom positioning. It is best understood as a productivity layer for teachers: it speeds up preparation and grading support, while lesson judgement and final decisions stay with the educator.
