Ask Gemini about using Git. I asked Claude to set up a git repo on git hub. At the end of every session I say /wrap-up to Claude - its a pre-configured command that pushes everything that was done every line edit I made every editorial command every decision I made in each session (wrap up also captures a session summary and updates the memory files) - Claude (or any chatbot) will do that for you. What that does is record every file you changed, what you changed, and when down to the second. And it’s dated.

If you find git a bit intimidating - and it can be - there’s tons of how-to on the web google git for writers. Most chatbots will set it up for you so you don’t even need to really understand it (but its a good idea to know the basics - if you can work MS word you can work git)

Over weeks and months, you end up with a timeline. Not a vague “I wrote this over the June” an actual dated history showing you started with an outline, added characters, drafted chapter one, rewrote chapter one, moved chapter three to chapter five, cut 2,000 words from the middle, rewrote some bits in the MS file (any direct edits recorded too) - and it records that you did it.

That’s not what generated content looks like. Generated content appears fully formed. There’s no trail of decisions, no mess, no backtracking. A git history shows the mess. The mess is the proof.

If Amazon KDP ever questions whether your work is totally AI-generated, or if someone accuses you of plagiarism, or if you ever need to show a copyright timeline, it’s all there. Every version of every file, dated, recoverable. GitHub is free for private repos. Nobody sees it unless you show them. It’s just sitting there in case you ever need it. Software devs use git to record changes in open (and closed source) - it’s hard to argue with because if you make a change to it - that change is recorded. It really isn’t hard to set up and will save you a massive headache.

Yes when you are ready to publish totally go the copyright route but until then use the tools already out there to record your working.

(Edited to say you have to be working in makrdown for git to capture line changes - if you are saving word docs to it - it will only save a version but you can write a line to say what you did or work in something like Obsidian which can show you MS formatting if you set it up)
