How do you build meeting agendas? (I made a tool for it, would love your feedback)

Hey Product Hunt makers 👋

I’m Adrian, a solo builder. I’ve been curious how people actually prep for meetings, because most agendas I see are either a forgotten bullet list in a calendar invite or a doc nobody opens until the meeting starts (or worse not at all 🫠).

I’d love to hear how you do it:

1. Do you write an agenda?

2. Where do you write agendas (Notion, Docs, calendar invite, Slack, paper)?

3. Do you time-box each item, or let the meeting run and "keep it in your head"?

4. Who contributes to the agenda: just you, or the whole team?

5. What’s the biggest reason your meetings run long or go off-topic?

I am frustrated with common practices and set out make meetings better (like so many before me) so I built BriefMe, a shared meeting agenda with a built-in timer. Everyone sees the same agenda, each item gets its own time block, and the meeting stays on track.
It also works with your AI-Assistant (no surprise): describe your meeting and it drafts the agenda for you, no login needed to try it.

I’m still shaping the roadmap, and try to understand if I should keeping shaping this project or if I am the only one with this issue, so honest feedback is welcome, including “I’d never use this because…”.
What would make a tool like this a no-brainer for you or your team?

Thanks for reading, and I’ll reply to every comment. 🙏
