Technique for Writing Entire Books

This is a very interesting thread. I wrote a non-fiction craft book about 40 years ago which was published and it’s now out of print. I’ve been thinking about republishing for sometime and I have experimented with chatgpt to edit some things I’ve written. My book is out of date the publisher no longer trades and gave me permission years ago to republish. My question is should I get AI to help me rewrite it? It will need lots of checking after but should I let AI loose on it to see if it can bring up to date? There are books on the market, particularly on Apple Books, and generally online, which haven’t been updated but are republished. Has anyone else had experience of editing with chatgpt? My main concern is it might be obvious it has been generated by AI.
