KaigiFlow carries a single continuous record from setup to export.
Before

During
Read live transcription and translation with stable speaker labels. Pause when you need to. The recording stays on your device.
After

When you will reach for it

Alongside video calls
KaigiFlow captures your Mac's system audio, so it works alongside call apps such as Zoom, Microsoft Teams and Google Meet. It runs as its own app next to the call, and no bot joins the meeting.

Students and lectures
Studying a language, or studying abroad? KaigiFlow shows each sentence of the class as text with its translation on your Mac, iPhone or iPad while the lecture goes on. Afterwards you have a transcript to study from.

Questions people ask
Meeting capture, supported languages and what happens to your recordings.
Does KaigiFlow join my Zoom call?
No. KaigiFlow captures your microphone or your Mac’s system audio, so it does not join the meeting as an extra participant. You can use that capture with a meeting running on your Mac. Tell the other participants you are recording and obtain any consent required where you meet.
Does my audio leave my device?
In Local mode, no. In Balanced mode, the audio stays on your device. In Sangei Cloud mode, with your agreement, Sangei Cloud hears the meeting audio for live recognition. Re-read and cloud imports also send recordings. Sangei Cloud does not keep the audio or its text. The Privacy Policy explains these choices, cloud reports and how long information is kept.
Which languages does KaigiFlow support?
You can follow up to three text outputs at once. Available meeting languages depend on your app build. See the list of supported languages
Which devices does KaigiFlow support?
iPhone 12 Pro and later, iPads that run iPadOS 17 or later, and Macs with Apple silicon and macOS 14 or later. Apple Watch works with a supported iPhone. Some features need a newer device or system version, and the app shows what yours can do. The download page lists the requirements.
