The Chat Stream plugin allows you to converse with GPT AI directly within Obsidian, using canvas notes as context. With a simple key combination, you can generate new notes based on your current note and its ancestors, and even control which other notes are sent to the AI for further discussion. The AI's responses are easily distinguishable by their purple color and specific tag in the canvas data file. This plugin is perfect for those who want to harness the power of GPT AI within their Obsidian workflow.
