AI can now translate your thoughts into text

Technology Nov 08, 2025

Scientists have unveiled "mind captioning," a new tech that uses AI and MRI scans to translate brain activity into written text.
Developed by a team including UC Berkeley researchers, it can pick out the right video from 100 options about half the time—way better than guessing.

Potential benefits and ethical concerns

This could be game-changing for people who can't speak, like stroke survivors, by helping them communicate through their thoughts.
But there are real concerns about mental privacy, especially as tech moves fast.
For now, the system can't fully decode private thoughts and still needs an MRI, but researchers hope future versions using brain implants will make it more practical—and accessible—for those who need it most.
