It supports configurable processing for YAML front matter and embedded notes to streamline workflows.

The Paperless plugin integrates Obsidian with a self-hosted Paperless-ngx instance, allowing users to seamlessly view and insert PDFs into their notes. It provides an overview of all available documents and enables one-click import, embedding external PDFs directly into the vault. This eliminates concerns about local storage while maintaining easy access to important files.

The PDF Writer plugin enables users to fill and annotate PDFs directly within Obsidian. It allows adding and editing text fields, customizing font settings, and repositioning annotations for a seamless document workflow. Users can modify PDFs with an intuitive toolbar and save changes without leaving their vault.
