Guests receive 720p and 15 minutes per day. Free registration unlocks 1080p and a total of 40 minutes per day; time already used still counts. Allowances reset at 00:00 Beijing time (UTC+8). Normal and invited casting share the screen sharer's daily allowance; watching does not count. Free includes one viewer, text chat and a watermark. Pro unlocks voice talk, 3 viewers, no watermark, unlimited duration and room passwords; Premium adds camera video calls, 5 viewers, 4K source quality, recording and custom branding. Captured screen audio is separate from voice talk and depends on browser and OS support.
A room link works for the duration of that session. The moment you stop sharing it goes dead — nobody can see anything through an old link.
Latency depends on both networks and devices. Direct peer-to-peer connections are usually responsive enough to follow the cursor; relayed connections can add some delay while prioritizing continuity.
