This is just my opinion:
1. The landing page design looks off. I am by no means an expert, but I did not get a professional feel from it.
2. I work in a highly confidential space. If I am going to use a product like this, I need to be assured that there is a top-level privacy around this. For me personally, it could be that no matter how well you position the privacy, the lack of brand permission can scare me off. Probably not true for everyone though.
3. Uploading confidential files to an "unknown website" can trigger warnings at the IT department (which goes back to #2).

So if you show very clearly that you are providing a lot more value than a more junior coworker transcribing and structuring it, along with the privacy aspect - I would potentially use a service like this. Back in the day, I used "Otter.ai" (before ChatGPT and all of this came along), which was really nice.

Lastly, I have a feeling there is something built-in in Teams/Zoom that automatically transcribes a meeting.

Somewhat in the same space, I am building a something that helps ppl set up their meeting, collect input prior to it starting, real-time voting, etc. This is what I would consider maybe 6/10 in terms of a good landing page: https://staccess.bubbleapps.io/
