Reliable real-world context sensing for mobile EEG and bio signals.
A compact wearable with contextual AI that captures and synchronises environmental events with neural data beyond the lab.
Works with any EEG system.
Direct trigger injection at the electrode level, no middleware, no adapters, no compromise.
Built for real-world
neuroscience research
Eliminate manual annotation and post-hoc synchronisation. Eventag enables precise, ecologically valid research outside the lab.
Real-Time Contextual Sensing
Detects and tags environmental events as they happen, starting with audio, synchronised precisely with your neural data stream. No post-hoc alignment needed.
AI-Powered Classification
Advanced algorithms automatically classify and label events in the environment, from auditory stimuli to physical interactions, with zero manual effort.
Direct Electrode-Level Injection
Trigger injection happens directly at the electrode level, making Eventag compatible with any EEG system, OpenBCI, mBrainTrain, or any mobile platform. No middleware required.
Precise Synchronisation
Proprietary E-cap hardware PCB design ensures millisecond-accurate alignment between environmental events and neural recordings.
Privacy by Design
No audio or video is ever recorded. Only extracted events and features are stored, ensuring participant privacy and full compliance with research ethics.
Plug-and-Play Workflow
No complex setup or calibration. Attach Eventag, connect to your EEG, and start recording. Designed to fit seamlessly into any existing research protocol.
From sound to
synchronised data
Eventag rides along your existing EEG setup, listens to the environment, and writes labelled, precisely timed markers straight into the recording.
Listen
Eventag processes ambient audio on the device in real time. No raw audio is ever stored, only what is needed to detect and describe an event.
Mark and classify
The instant a sound begins, Eventag injects a precise marker electrically at the EEG electrode, then classifies the event and adds its time and confidence.
Align and export
Every marker is time-locked to your raw EEG, with a rich feature file capturing environmental context for post-hoc analysis.

Frequently asked questions
Eventag is a wearable device that automatically detects real-world events and writes them into an EEG recording as precisely timed markers. Brain data recorded outside the lab arrives already annotated, with no manual tagging after the session.
Yes. Eventag is hardware-agnostic. It works alongside common research-grade EEG systems and electrode setups, and fits into the recording pipeline you already run, so there is no need to replace equipment you have already validated.
Eventag processes sound on the device and stores only the event label and timestamp, never raw audio or video. That makes it suitable for everyday and public settings, and easier to defend before an ethics board or under GDPR.
Eventag time-locks each detected event to the EEG data with millisecond-level precision, tight enough to support event-related analysis rather than approximate alignment.
