If you use something like youtube-dlp you can download the audio from the meetings, and you could try things out in mistrals ai studio.

You could use their api (they have this snippet):

```curl -X POST "https://api.mistral.ai/v1/audio/transcriptions" \ -H "Authorization: Bearer $MISTRAL_API_KEY" \ -F model="voxtral-mini-latest" \ -F file=@"your-file.m4a" \ -F diarize=true \ -F timestamp_granularities="segment"```

In the api it took 18s to do a 20m audio file I had lying around where someone is reviewing a product.

There will, I'm sure, be ways of running this locally up and available soon (if they aren't in huggingface right now) but the API is $0.003/min. If it's something like 120 meetings (10 years of monthly ones) then it's roughly $20 if the meetings are 1hr each. Depending on whether they're 1 or 10 hours (or if they're weekly or monthly but 10 parallel sessions or something) then this might be a price you're willing to pay if you get the results back in an afternoon.

edit - their realtime model can be run with vllm, the batch model is not open

> 10 years worth of monthly meetings

if it's 1 monthly video and thus 120 videos (or so) you could try recall (getrecall.ai not recall.ai that is a similar product with a similar name). They summarize youtube videos, but you get the transcript. AFAIK you cannot batch the processing and you have to add each video one by one, that's why 100 or 200 videos is doable but probably not thousands.

- get an API key for this service

- make sure you have a list of all these YouTube meeting URLs somewhere

- ask your preferred coding assistant to write you up a script that downloads the audio for these videos with yt-dlp & calls Mixtrals' API

If they are on Youtube, try Gemini 3 Flash first. Use AI studio, it lets you insert YouTube videos into context.
