How it works
1
Design the banner
Lay out the event name, date, speaker and venue over your event branding.
2
Render per session
Loop over your schedule and render a card for each talk, speaker or reminder.
3
Share everywhere
Post them to social, embed in emails, or hand speakers their own promo cards.

Can I generate one per speaker automatically?
Yes — render in a loop or a no-code flow so every speaker and session gets its own card without manual design.
What sizes can I render?
Any — templates are size-specific, so you can output square social, wide banners and story formats from the same data.
