    I made sure to document every step of the way via screenshots to ensure I could test enabling and disabling certain features. The screenshot tool I use on Windows is called, ShareX, and I find it extremely useful with regards to pointing out certain elements in an image.

    OP, you probably shouldn't say "runs directly in your browser" if it sends screenshots to a cloud service.

    If anyone wants a similar tool for Windows that does the OCR locally instead, I recommend Text Grab (https://github.com/TheJoeFin/Text-Grab). I use it a lot for reading manga; works great.
