Local Video Transcription and Search Solution for Podcast Archives

I’m looking for a program that can run alongside my NAS to transcribe videos and make them searchable by keywords. The podcast I work for has been running for 2 years, and with so many files, it’s getting tough to find specific clips from the past year. Ideally, I’d like something that:

• Runs locally (preferably on the NAS).
• Has a web GUI or user-friendly interface.
• Allows me to search keywords to quickly locate the content I’m after.

Does anything like this exist?

Side Note:
I came across Shade.inc, and it looks amazing for organizing and accessing files. I’d love something similar but tailored for running on a NAS. Having remote editors access files directly from the NAS instead of relying on Google Drive would be a game-changer. If anyone has thoughts or recommendations on that kind of setup, I’d really appreciate it!

THANKS in advance for your help!
