Upgrade your Buddy to Research Edition with full parameter control, four waveform modes, Chrome Control Surface, and AI-powered MCP device control via Claude.
Requires Vagal Buddy (tVNS Stimulator) with firmware 5.2 or above.
“After only 2 weeks I noticed a huge difference. I just purchased one for both my brothers.”
— Verified buyer, daily useResearch Edition is a firmware upgrade that unlocks full parameter control, professional tooling, and three major new capabilities. Same hardware. Entirely new level of control.
Everything you need to turn your Buddy into a fully programmable research instrument.
Symmetric, alternating, asymmetric and monophasic pulse shapes. Match your stimulation to the protocol rather than being limited to a single waveform.
Full-featured control panel running in your browser. Connect via Web Bluetooth, see live waveforms, drag faders, manage sessions. No app install required.
Connect Claude to your stimulator via the Model Context Protocol. Set parameters, start sessions and monitor HRV through natural conversation with AI.
Set stimulation to precise microamp values. No more guessing with intensity levels.
Frequency, pulse width, interphase, duty cycle, anti-habituation. Every parameter exposed.
Wireless Bluetooth Low Energy connection. Control your device from across the room.
Post-session HRV analysis with timeline charts, phase comparisons and stimulation correlation.
Configurable sham stimulation for blinded research. Set ramp, min current and max duration.
Programmatic device control for automated study protocols and custom integrations.
Match pulse shape to protocol. Symmetric for standard studies, or unlock alternating, asymmetric and monophasic waveforms for advanced research designs.
Equal positive and negative phases. The standard for most tVNS research protocols. Charge-balanced by design.
Flips leading polarity each cycle. Reduces electrode polarisation and may improve nerve fibre recruitment patterns.
Short high-amplitude cathodic phase with a longer, lower anodic return. Targets specific fibre types while maintaining charge balance.
Single-phase pulse with no return. Maximum directional selectivity for protocols that require unbalanced stimulation.
No app required. Open the tVNS Control Surface in Chrome and connect directly to your Buddy via Bluetooth. Every parameter at your fingertips.
See your target current and what the device is actually delivering in real time on a dual-arc gauge.
Canvas-rendered oscilloscope shows your exact pulse shape, timing and interphase in real time.
Visual timeline shows on/off periods, elapsed time and session progress at a glance.
Talk to Claude. It talks to your stimulator. Set parameters, start sessions, and adjust protocols through natural conversation using the Model Context Protocol.
Research Edition transforms your consumer Buddy stimulator into a programmable research instrument with full parameter access and professional tooling.
