Questions, answered plainly.

Larch uploads none of your audio or text. Speech recognition and speaker labels run on your PC. Its one network call is an update check at launch and every 6 hours, which sends your license id and nothing from your meetings.

No. There’s no Larch server that receives audio or transcripts, and no account. We hold your email, your billing records from Stripe, and update-check logs.

One Markdown file per meeting, named like 2026-11-10 1400 Weekly sync.md, in Documents\Meetings unless you choose another folder. They’re plain text and aren’t encrypted, so keep them where your work files belong. If that folder syncs to OneDrive or another service, the files sync too.

It’s encrypted to your Windows account while it waits, then deleted once the transcript is saved. If transcription fails, Larch keeps the audio and tries again.

No. Telling speakers apart happens in memory during one meeting. Nothing about anyone’s voice is saved, even on your PC.

No. Belted Labs never receives your meetings, so there’s nothing to train on.

No. Larch doesn’t join the meeting, so people won’t know unless you say so. You’re responsible for telling people on the call and following your company’s rules. Say it at the start, or paste: “Quick note: I’m taking a transcript of this call on my laptop. Nothing gets uploaded. Tell me if you’d rather I didn’t.”

It depends on where you and the other people are. Some states, including California, Florida, Illinois, Pennsylvania and Washington, require everyone on a call to agree, and calls across states can carry the stricter rule. Larch can’t decide this for you, and this isn’t legal advice. The simple habit: tell people every time.

That’s your company’s call. Many companies only allow software their IT team has reviewed. Send them the For IT page, which covers everything Larch does on a PC.

Yes. Choose Stop recording in the tray menu, or quit Larch before the call. Larch starts at login by default; you can turn that off in Settings.

Microsoft Teams, Zoom, and Google Meet in Chrome or Edge. For in-person meetings, start it from the tray or press Ctrl+Alt+M. In a browser, Larch hears the whole browser, so close other tabs that play sound.

Larch uses Whisper, a widely used open speech model, running on your PC. We haven’t measured accuracy on real calls yet, so expect errors with crosstalk, accents and jargon. Check names and numbers before you quote them.

Larch starts when the call ends. The target is 25 minutes or less for an hour-long call on a work laptop; your PC’s speed decides it. You’ll see “Transcript ready” after the call, never during it.

Yes. Copy transcript puts the full text, with names and times, on your clipboard, formatted for OneNote. Every meeting also exports as Word (.docx) or plain text.

Not in 1.0. Larch writes the full transcript. Notes that file themselves are coming, and none of that ships today.

Copilot runs in Microsoft’s cloud for meetings in your company’s Teams. In a Teams call hosted by another company, an outside attendee can’t download a transcript afterward. Larch writes one on your PC for any Teams, Zoom or Meet call. See the full comparison.

Recording stops. Every transcript stays in your folder, readable and exportable. Add a key and Larch records again.

No. Larch installs for you only.

Larch is built and tested for Windows 11. Windows 10 isn’t confirmed yet. Mac comes next.

Settings > Apps > Installed apps > Larch > Uninstall. Your transcripts stay in your folder until you delete them.
