Made this after accepting I'll never update my 200+ old posts, but readers still want answers from them. Plugin adds "Ask ChatGPT about this" buttons – but readers can customize the prompt. Tracks what they change it to as WordPress comments (yes, reviving that feature).

It's basically admitting your content isn't complete, but making that useful. GDPR-compliant, local analytics, works retroactively. Bad idea or pragmatic solution?
