The core trick — record each participant's audio and video locally in the browser, then upload separately for studio quality — is a well-documented technique. Keeping every participant perfectly in sync afterward is the fiddlier part.

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $43–$86 one-time |
| Hosting, once it's running | $23–$46/mo |
| Domain name, if you want your own | ~$12/yr |
Riverside.fm costs $19/mo, but hosting alone could run $23–$46/mo — that can eat the whole subscription saving before the agent cost even comes into it.
Borderline. The core trick — record each participant's audio and video locally in the browser, then upload separately for studio quality — is a well-documented technique. Keeping every participant perfectly in sync afterward is the fiddlier part.
Riverside.fm costs $19/mo (about $228/yr) as of 2026-08. That's what a working rebuild would save you.
Keeping separately-recorded local tracks perfectly synchronized after upload, despite network jitter and device clock drift, takes real care to get right Their AI-powered editing features (auto-generating clips, removing filler words) are a separate, more sophisticated capability Live streaming the recording session to platforms like YouTube simultaneously adds real broadcast-infrastructure complexity
