A live poll with results updating in real time on everyone's screen is a genuinely achievable WebSocket build. Handling thousands of simultaneous audience members reliably is where the real infrastructure care lives.

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 | $5–$10/mo |
| Domain name, if you want your own | ~$12/yr |
Slido costs $20/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 9 months.
Borderline. A live poll with results updating in real time on everyone's screen is a genuinely achievable WebSocket build. Handling thousands of simultaneous audience members reliably is where the real infrastructure care lives.
Slido costs $20/mo (about $240/yr) as of 2026-08. That's what a working rebuild would save you.
Reliable real-time delivery to a large conference audience (thousands of simultaneous connections) is a genuinely different scale of infrastructure than a small meeting Presentation software integration (embedding live results inside PowerPoint or Google Slides) is a real, separate integration Moderation tools to filter inappropriate live questions at scale need real content-review workflow
