Real talk: practical tip from someone who reviews a lot of startup IP portfolios: if you're building a company that relies on AI-generated or AI-assisted content, start a "creative contribution log" NOW.
I've been advising my clients to maintain a simple spreadsheet for each significant piece of content: date created, AI tool used, description of prompts, percentage of final text that was human-written or substantially modified, and the name of the person who did the editing. Attach before/after versions if possible.
This does two things: (1) it strengthens your copyright registration if you ever need to file one, and (2) it's gold during due diligence. I've seen three acquisition deals in the past year where the buyer specifically asked about AI usage in content creation. The companies that had documentation sailed through. The ones that didn't had to scramble or accept IP escrow provisions that delayed closing.
Five minutes of documentation per piece of content can save you weeks of headaches later. Especially as the legal landscape continues to evolve and more companies start scrutinizing AI-generated IP in transactions no cap.
