AI-MarkDone - Make ChatGPT feel built for serious work.

Hey Product Hunt, I’m Liangbin, the maker of AI-MarkDone. I built this because ChatGPT had become part of my daily research and coding workflow, but the useful answers were still awkward to use after the conversation moved on. A good answer might have a derivation, a table, a code block, or a formula I wanted to keep. Then I would scroll around to find it again, copy it into notes, fix broken Markdown, clean up LaTeX, or take a screenshot because the answer was easier to see than to reuse. Small annoyance, repeated a lot. AI-MarkDone is my attempt to make ChatGPT feel built for serious work. It adds a Reader mode for long answers, partial Markdown copy, formula copy/export, bookmarks, precise annotations, Google Drive bookmark backup, and Markdown/PDF/PNG/ZIP export. The goal is simple: read better, capture the useful parts, and keep them available after the chat moves on. I kept the product focused on ChatGPT because that is where I felt the pain most. I’d love feedback from people who use ChatGPT for research, study notes, code explanations, writing, or technical work. What still breaks for you when you try to turn a good ChatGPT answer into something you can actually keep?
