Why? OpenAI's Whisper is a free local model with native GUIs on most operating systems. I wrote one myself in a weekend, it's one of hundreds of similar GUIs that exist.
What functionality would you be offering that people can't otherwise get for free? This is a pretty competitive space, trying to sell a TUI is going to leave you gravely disappointed by the sales (unless it's extremely impressive).
