PinAI - AI Knowledge Library

What it does

AI conversations produce great outputs that vanish into scroll history. PinAI fixes this. Click the pin icon on any AI response in Claude, ChatGPT, or Gemini to save it to a project board. Add notes about why you saved it. Add action items for what to do next. Then re-inject saved outputs into new conversations as context. Free, open source, and 100% local — your data never leaves your device. No accounts, no cloud, no tracking.
