The best Chronicle Bot alternative
for Discord events & TTRPG sessions
Frustrated with Chronicle’s steep command curve, missing two-way Google Calendar sync, and clunky session scheduling? Atomcal runs native Discord Scheduled Events with automatic timezones and calendar sync — built for D&D tables and gaming servers.
- Native Discord Scheduled Events
- Auto timezone · no UTC math
- Migrate in ~2 minutes
Quick answer
Is Atomcal better than Chronicle Bot?
Yes — for tables that need to grow. Chronicle is still slash-command bookkeeping. Atomcal’s extensions do what Chronicle doesn’t: Discovery publishes a public campaign page for recruiting, Magic Invites fills sessions from players who show up, and Member Analytics tracks who’s at the table over time.
