Software

Offline-first tools

Software for debate tournaments, Model UN and online communities that keeps working when the venue Wi-Fi doesn't.

DebateTypeScript

Debate Adjudicator

The chair's phone or laptop runs the room: synced timer and bells over local Wi-Fi, POIs from debaters' phones, offline Whisper transcription, ballots and PDF reports.
