## Summary

Georgia Tech researchers built ORISA, a tool that searches an Android device's memory for remnants of deleted local AI chats. In a test using the ChatterUI app, it restored 26 of 100 fictional facts, compared with 14 that the original session still held. The researchers say the tool is aimed at cybersecurity investigations, and recovery becomes harder as newer activity overwrites memory.
