Capture: the mic runs continuously. Say note — or clip, point, review — speak your feedback, then say done. Only the audio between the two words is kept: the app reads the waveform to find where your feedback actually starts, so the trigger word stays out of the clip.
Clipping what just happened: say clip the last play and the row is stamped with the 30 seconds before you spoke — the moment, timed against the match clock, so footage filmed on another device lines up with it afterwards. After “clip” it waits a couple of seconds for the rest of the command, so you can add a length and a camera number: “clip the last 20 seconds camera 3”. Both go straight into the table. Either order works, and any comment you add afterwards is kept as the note.
For clean clips and better recognition: leave a small beat after saying “note” — the cut then lands exactly in that gap. Keep the mic close and out of the wind. Set your headset as the Windows default input: the recogniser always uses the system default, even if you pick a different mic above. And add nicknames for anyone whose name gets mangled — those are matched too.
Filing: the app looks for squad names (including nicknames, surnames and near-misses) and position references (“left back”, “the six”, “our right winger”, “the back four”, “everyone”). Names win over positions. Anything it can't pin down lands in Unassigned.
Working offline: the match itself needs no connection. Signing in is remembered, so opening Relay with no signal keeps you signed in; the team sheet, the pitch, substitutions, recording, trimming, filing, half time, the clip table, playback, the exports, saving a match and reopening a saved one all run on the device.
What does need signal: speech recognition, unless you have installed the offline voice — press Download offline voice under ⚙ while you still have bars, and the trigger words keep working with none. Without it you lose the triggers and transcripts only: clips still record with the Note button and typed notes are still filed. Finding and connecting to other coaches needs signal, as does sending clips to players — those are queued and sent when you are back.
Other limits of a browser build: recognition stops if the tab is backgrounded or the phone screen locks; and everything is held in memory, so a refresh wipes the session.
