Metadata Auto Classifier
Tags and frontmatter, written by the model you choose.
An Obsidian plugin that analyzes a note and generates tags and frontmatter values with a configurable AI provider. Define any field, add rules and per-field context, preview before applying.
Open a note, run one command, and the plugin proposes tags and fills the frontmatter fields you defined. Classification rules, tag categories, and per-field context prompts steer the model; the more context you give, the more accurate the result.
Built-in presets cover OpenAI, Anthropic, Gemini, OpenRouter, Ollama, DeepSeek, LM Studio, and Codex, plus any custom provider. A preview mode shows the proposed changes before anything is written to the note.
