About
You can now use Plannotator to annotate anything! Free, open source, and private (runs local). Use the skill /plannotator-annotate (or cli) - followed by a folder, URL, document, markdown, your book, a recipe, a plan, etc - to annotate anything and send feedback directly into your integrated agent. Use /plannotator-last to annotate the last message an agent sent you too. I like using it for my own version of Karpathy’s "LLM Wiki" in obsidian. https://github.com/backnotprop/plannotator
