# Obsidian Plugins

I've been a fan of [Obsidian](https://obsidian.md/) for a long time, and used it as a CMS for a period of time. You can read a bit about those iterations [here](https://iammatthias.com/posts/1670659200001-obsidian-as-a-cms), [here](https://iammatthias.com/posts/1699332127006-revisiting-obsidian-as-a-cms), and [here](https://iammatthias.com/posts/1710177704945-revisiting-obsidian-as-a-cms-again).

Along the way, I built 3 plugins that I found useful:

- Obsidian Pinata Image Uploader: [REPO](https://github.com/iammatthias/obsidian-pinata-image-uploader)\
Uploads embedded images to [Pinata](https://pinata.cloud/). The plugin replaces both local and remote image references in markdown with `ipfs://` URIs, and handles gateway proxying for image display.
- Obsidian AI Excerpt Generator: [REPO](https://github.com/iammatthias/obsidian-ai-excerpt-generator)\
Generate concise excerpts for Obsidian notes using AI. The plugin adds or updates the `excerpt` field in each Markdown file's frontmatter.
- Obsidian AI Tagger: [REPO](https://github.com/iammatthias/obsidian-ai-tagger)\
Generate relevant, consistent tags for Obsidian notes using AI. The plugin adds or updates the `tags` field in each Markdown file's frontmatter.
