@Em0nM4stodon To add a bit more, the AI program I used runs on a desktop computer. It found spastic-typing mistakes such as double commas and some bad editing - changing a noun from singular to plural, getting interrupted by someone with a pressing problem, and then forgetting that I hadn't changed the verb. It probably saved energy - otherwise the computer would have had to be turned on longer due to having to read all that text - over 400 pages - carefully.
