The median salary in the US is $29/hour.
By definition a one hour meeting has at least two people in it; often more. So two median guys talking for an hour costs ~$60. The meeting the you really want transcripts for often contain more than one person; and often involve people earning more than the median. I'd happily ad $1 to every single one of my meetings if they get more productive.
$0.70/hr is our starter rate for low-volume testing. In production, developers will see higher usage and choose to commit to volume and longer-term usage. Because of this, we've seen most teams don’t pay the starter price once they scale beyond early pilots
Enabling transcription/recordings per platform and remembering to record creates user-dependent setup. Also the host often needs to install apps which adds security friction, and you still have to build/maintain separate implementations for Zoom/Meet/Teams which is often a cost that devs don't want to deal with
Instead, we built a single API that can get the same results without the issues mentioned above so you can focus on building the features your users care about
It is a lot but processing real time video and audio streams inherently consumes alot of CPU. So they may not be making as much profit on that price as you'd think.
I run an open source alternative to Recall (for meeting bots), and our costs are about 8 cents per hour.
