FWIW if you are interested in such tooling consider also soffice
and pandoc
which have (as far as I can tell) similar features but have been existing for years now and are not related to Microsoft.
Edit: not related to Microsoft AND Google, seems the transcription aspect (which IMHO is still weird in that context but OK) is done via Google servers, cf https://lemmy.ml/post/23629310/15586865
