I had tried different ways to build a workflow to redact sensitive info from documents in the past like writing a python script but I never got back to them after a day.
This time, I had low expectation, specially because what can you do with wasm! It did pretty well + the browser interface with manual control to blur stuff, it did the trick for me to make it to my daily usage. Demo link in the repo. Free, local, in-browser.
Seeking more ideas to improve the project further.
