Open-source tutoring, built for real lessons

Teach live, on a whiteboard that feels like paper.

Helix brings HD video, a pressure-sensitive collaborative whiteboard, and a chemistry toolkit into one room — so tutors and students can work side by side from anywhere.

Platform features

Real-time HD video

Self-hosted, low-latency 1:1 and small-group rooms with active-speaker focus and graceful recovery from network drops.

Pressure-sensitive whiteboard

An infinite, multi-page canvas with paper-like pen ink, live cursors, and conflict-free collaboration that survives reconnects.

Chemistry toolkit

Render reaction equations, draw molecules, and rotate 3D structures — all shareable live in the room.
