I tried their Mac app for a while, but the storage space required quickly became impractical for a retention period set to any actually-useful amount of time. I wonder how they've handled that here.

If all they need is voice, they could just transcribe it. That'd probably be a few KB per day.

I've been thinking about doing something like this myself. Lyra[0], a codec by google, supports speech @3.2kbps (0.0004 MB/s), so 3.26060*24/1024/8, or 33.75MB/day. Filtering out periods of inactivity, it's likely under 10MB a day.

I feel like my math must be wrong, because this feels crazy!!
