An Otter.ai alternative that keeps your meetings on your device

I make Karl, so read this knowing that. Otter and Karl both turn a meeting into a transcript and a summary. The difference is where that happens. Otter uploads your audio and does the work on its servers. Karl does all of it on your iPhone or Mac, and nothing is uploaded.
