## Sound familiar?

Screen freezes past 500 viewers. Every company-wide townhall starts with "how many can it handle?" anxiety.

Tracking attendance manually. After each live session, another hour spent cross-checking attendance in spreadsheets.

No meaningful interaction. "Any questions?" is met with silence in chat, and the session becomes a one-way broadcast.

- Live Chat & Quiz

Set chat mode to one of 3 options (Off / Admin Only / Everyone). Launch quizzes during broadcast and check participation and accuracy rates in real-time. Send push notifications to target groups so learners join the broadcast with one tap.

- QR Attendance & Channel Access Control

Verify attendance instantly with QR check-in, then set channel viewing permissions for individuals, bundled groups, or all groups. Manage channel names (up to 70 chars), descriptions, and stream latency per channel. Non-live channels can be edited or deleted, and the LIVE status filter shows only active broadcasts.
