Person AI (Project Korolev)

Right now most of psychological/therapy/case work is recorded by hand and kept in patient files/books. This is very manual and is terrible in terms of figuring out how well the patient is doing over their entire patient history over all sessions. (The practitioner canā€™t possible read it all, and get full context of the patientā€™s current state) The Generative AI solution can potentially help practitioners to summarize and draw insights, to improve and speed up reviewing patient history.

RepoSense

RepoSense can generate interactive visualizations of programmer activities, even across multiple repositories. It's ideal for educators and managers to get insights into the programming activities of their mentees. The visualizations can be easily shared with others (e.g., as an online dashboard), and updating the visualizations periodically can be automated.
