Record Slack huddles on your Mac.

Keep a record of the spoken discussion

Slack messages capture what people type. A huddle often contains the explanation, trade-off, or agreement that never reaches the thread. echo99 records your microphone and the huddle audio playing on your Mac as two separate tracks, then creates a local transcript with speaker labels once the huddle is over.

How to record a Slack huddle

1. Install echo99 and complete the initial setup: microphone and system audio recording access, plus the transcription models.
2. Join the huddle on your Mac. Use headphones to keep the other voices out of your microphone track. echo99 records your Mac’s default input (System Settings → Sound → Input), so pick the same microphone in Slack.
3. Open echo99 in the menu bar and click Record.
4. Click Stop Recording when the huddle finishes. Open Recordings to read the transcript and play back the discussion.

Before relying on it for an important huddle, make a short test recording and listen to both sides. While it records, keep an eye on the menu-bar panel: after about 90 seconds of sound on one side and silence on the other, it shows “Mic looks silent” or “System audio looks silent”. Recordings are saved in ~/Documents/echo99/, one folder per huddle named by its start time; Config → Storage changes the location.

Huddles start on short notice, so Auto-record calls in the menu-bar panel can help: echo99 starts recording a few seconds after Slack starts using your microphone and stops shortly after you leave the huddle. If you only listen with no microphone in use, start recording manually.

Slack AI notes and your own local recording

Slack already offers AI huddle notes on paid plans. They include topics, action items, and an embedded transcript in a canvas shared in the huddle thread. Slack currently excludes huddles with external people or guests from that feature.

Choose echo99 when you want audio and notes saved as files on your own Mac. It does not post to the thread or create a Slack canvas: you decide which notes to copy or share. To add AI notes locally, install a model and follow the meeting summaries guide.

What is saved, and what is not

• Audio and text. Keep separate microphone and system-audio WAV files, a timestamped transcript, and a Markdown summary when generated.
• Spoken conversation only. echo99 does not capture Slack messages, reactions, video, or shared screens. Paste useful links into your notes separately.
• Speaker labels come from audio. echo99 does not read Slack profile names. You can name voices and use local speaker recognition for familiar people.
• Your Mac stays in the huddle. Keep it awake. Other audio playing on the Mac may be recorded too; pause music and avoid notification sounds.

Tell people you are recording

echo99 never joins the huddle, so nothing like Slack's AI notes notification tells the others you are recording. Many jurisdictions require the other side’s consent, and your organization or the host may have rules of its own. Say it out loud at the start, before the conversation gets going.

Slack feature details checked in October 2026. See Slack’s AI huddle notes documentation for current availability and sharing behavior.
