I built this out of my own frustration. I spend a lot of time in ChatGPT, Claude, Gemini and the best outputs always ended up scattered across dozens of chat threads. I'd copy-paste into random docs, lose track of where something came from, and end up re-prompting for things I'd already gotten great answers to. Sidepad is a Chrome extension that lives in your browser's side panel. You highlight text on any page, hit a keyboard shortcut, and it lands in a structured Markdown document. It's designed specifically for capturing from AI conversations, but works on any webpage. A few things I care about with this: - Local-first: your documents save as .md files on your machine. Nothing gets uploaded anywhere. No account, no cloud sync, no tracking. - Zero friction: no onboarding, no setup wizard. Install it, use the shortcut, done. - Free: no paywall, no premium tier. I'd love to hear about whether you find this useful for capturing ideas, organizing them and giving you reference points as you go through your AI chats.
