Frequently asked questions

Everything people ask before their first meeting.

Is SentinelSphere Meetings really free forever?
Yes. Every core feature — unlimited meeting length, unlimited participants, HD video, screen sharing, chat and recording — is free. There is no paid tier hiding features, and we never ask for a credit card.
Are there any time limits on meetings?
None at all. Your meeting continues until you end it. A session can run for 5 minutes or 5 hours — we will never cut you off.
How many people can join one meeting?
There is no fixed participant cap. Rooms comfortably support large sessions, and hosts can add observers, waiting-room guests and breakout groups without extra charges.
Do participants need to install anything?
No. SentinelSphere Meetings runs entirely in the browser on desktop, tablet and mobile. Just share the link — that's the whole setup.
Can I use it for research and interviews?
Absolutely. The research workspace adds consent notices, waiting rooms, silent observer seats, timestamped notes and unlimited recordings — all included for free.
Are recordings included?
Yes. Recording is free and unlimited. Recordings are stored in your workspace so you can revisit, download or share them with your team.
