# Meta Achieves Brain-to-Text Decoding Without Surgery Using AI

> Meta's AI researchers say their Brain2Qwerty v2 system can decode what a person is typing directly from their brain activity, reaching 61 percent word accuracy on average and 78 percent for the best participant. The striking part is how it reads the brain: not with surgical implants but with magnetoencephalography, a non-invasive scan that measures the tiny magnetic fields produced by neural activity. The numbers mark a large jump from earlier non-invasive attempts, which languished around 8 percent. Trained on some 22,000 sentences, the model learns to map patterns of brain activity to the keys a person intends to press. That leap from single digits to 60-plus percent accuracy is what makes this more than a lab curiosity, even if it is still far from reliable. The appeal of a no-surgery approach is obvious for people who have lost the ability to speak or type, since implants carry real medical risk. The caveats are equally clear: MEG machines are room-sized and expensive, and the accuracy is not yet practical. But the trajectory, and the privacy questions that come with any technology that reads intent from the brain, is worth watching closely.
