The event ends. The conversations shouldn't.
Most conferences spin up a free Slack workspace, watch it come alive for a week, and see it hidden 90 days later. Probed keeps every conversation, for one price per space.
A free Slack workspace, or Probed
Slack is a fair default: everyone knows it and a free workspace takes minutes. But its free plan hides messages after 90 days and deletes them after a year, so the speaker Q&A disappears just as you start planning the next edition. Upgrading means paying for every attendee.
Why it fits
- One link on a slide
- Put the join link on your opening slide or badge QR code. Attendees join in the browser, no install needed.
- A channel per track
- Announcements, schedule changes, a channel per track, and a voice room with screen share for remote attendees.
- Nobody pays per seat
- One monthly price for the whole space, and attendees never pay.
- The archive stays
- History never expires on any plan, so next year's edition starts with every answer from this one.
Set it up
Create a space named after the event.
Add announcements, general and a channel per track, plus a voice room.

Why not use a free Slack workspace for our conference?
Slack's free plan hides messages and files older than 90 days and deletes them after a year, so the event's Q&A and shared links disappear on a timer. Probed keeps full history on every plan, and attendees join with one link.
How much does Probed cost for an event with hundreds of attendees?
Pricing is per space, never per member: Premium is $19 a month for up to 250 members and Business is $99 a month for up to 2,500. Attendees join free, and both paid plans start with a 14-day free trial.
Do attendees have to install an app?
No. The join link opens Probed in any browser. There are also apps for macOS, Windows, Linux and iPhone.
