## What it is
An Obsidian plugin that lets users open and annotate PDF and EPUB files directly inside Obsidian. It is based on Hypothesis but stores annotations locally in markdown files instead of on the web.

## Use cases
- annotate pdfs inside obsidian
- read and highlight epub books in obsidian
- store pdf highlights as markdown notes
- take reading notes linked to my vault
- highlight academic papers and save quotes to markdown

## When to choose
- you already use Obsidian and want PDF/EPUB annotations saved as local markdown
- you want annotations with block references you can link and embed in notes
- you prefer local storage over a cloud annotation service

## When to avoid
- you need iOS support on iOS 16.3 or higher
- you need collaborative or cloud-synced annotations
- you frequently rename source PDF/EPUB files, which breaks annotation links

## Facets
- artifact type: plugin
- maturity: maintenance
- function: pdf-viewer, editor, markdown
- domain: pdf, developer-tools, text-editors, files
- platform: cross-platform
- tags: obsidian-plugin, epub-reader, pdf-annotation, hypothesis, note-taking, desktop
