AI Tagger is an Obsidian (https://obsidian.md) plugin that simplifies tagging by using various Large Language Models (LLMs) to analyze and tag your document with one click!
The plugin analyzes the current document that you have open in the editor and all of the previous tags that you have used. AI tagger will return up to 5 relevant tags that you have previously used and will generate up to 3 completely new tags.
