How to link research notes with wikilinks and attach PDFs and images with Opensidian

Connect notes with wikilinks, review backlinks and the graph, and drop source files into notes.

Who it is forA researcher or student who collects papers, screenshots, and notes and needs to see how ideas connect.

The problemResearch material spreads across files, and they need one place to link ideas and keep the sources next to the notes.

The outcomeNotes link to each other, backlinks and the graph show the connections, and PDFs and images sit in the vault next to the notes.

What you need first

  • A Linux x86_64 machine (the README lists Linux x86_64 only)
  • For the DEB path: a Debian or Ubuntu system with sudo access
  • For the source build: build tools, WebKitGTK 4.1 development packages, and Rust 1.98.0

Steps

  1. Open your research vault in Opensidian.
  2. Write notes and connect them with [[wikilinks]] between related topics.
  3. Open the backlinks panel and the graph view to review how notes connect.
  4. Drag a PDF from your file manager onto a note; the original stays and ![[name]] is inserted where you dropped it.
  5. Drag a png, jpg, gif, or webp image onto a note; the image is moved into the vault and ![[name]] is inserted.

Prompt for your agent

In an opensidian vault at <vault-path>, list the notes that contain [[wikilinks]] to <topic-note>, and report the names of notes that link back to it. Verify that each reported link target exists as a file in the vault before listing it.

Caveat. The README says a PDF must really start with %PDF- to be accepted, and other file types are refused and left where they are.
