AISummary of 4 articles

Sabi has raised $50M from Khosla Ventures, Accel, Initialized, Kevin Weil, DST Global and others to build a non-invasive wearable cap that it says will let people talk to AI agents by thinking.

The company's announcement describes 100,000 sensors, and a report citing its claims says the device reads brain signals through a custom chip and decodes them into text using Sabi's own AI model. Reports differ on details: one says the cap predicts a user's next three to four keystrokes before they type, another cites a reported $600M valuation, and another says the company designs its own TSMC-fabricated EEG chip. These are company claims; the reports do not establish a working prototype, measured performance, or a release timeline.

    Sabi raises $50 million for a wearable brain-to-text cap

    AISabi has raised $50 million from Khosla Ventures, Accel, Initialized, Kevin Weil, and DST Global to build a wearable brain-computer interface. The company says its TSMC-fabricated chip reads brain signals without touching the scalp, with custom sensors collecting data and its own AI model decoding it into text. The device is a cap rather than an implant.

    Sabi raises $50M for a wearable brain-reading cap

    AISabi has raised $50M from Khosla Ventures, Accel, Initialized, DST, and Collab Fund, with Kevin Weil also participating. The company is building the Sabi Cap, a non-invasive wearable that aims to read brain signals and turn thoughts into text. Sabi says it designs its own custom chips and neuroimaging sensors, including a non-contact EEG chip fabricated by TSMC.

    Sabi raises $50M to build AI brain-reading baseball cap

    AISabi has raised a $50M seed round led by Vinod Khosla and Accel to build a baseball cap that turns brain signals into AI prompts. The cap can hold up to 100,000 sensors of 1 to 5 millimeters each, feeding a brain foundation model trained on 100,000 hours of labeled neural recordings. Sabi says the cap can predict a user's next 3-4 keystrokes from brain signals before they type them.
