SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automatically fetches the authentic figures from arXiv source tarballs and embeds them into the per-paper Wiki/sources/<id>.md.

Core Features & Use Cases

  • Figure extraction: Retrieve figures from arXiv tarballs located in standard directories (figures/, fig/, photos/, images/) and attach them to Wiki/sources/<id>.md.
  • Automated embedding: Convert extracted images into Obsidian-friendly wikilink-with-width syntax to display in the per-paper note.
  • Use Case: When reviewing a paper digest, pull the architecture diagram or experiment plots to enrich the digest with concrete visuals before deep-diving.

Quick Start

Instruct paper-wiki to extract figures for arxiv:2101.01234 to embed them into Wiki/sources/2101.01234.md.

To extract figures from arXiv papers into Obsidian, fetch images from the arXiv source tarball and embed them into Wiki/sources/<id>.md using Obsidian wikilink-with-width syntax. This automatically enriches your paper digest with authentic visuals.

What is the best way to add architecture diagrams to research notes?

Adding architecture diagrams to research notes is best done by extracting authentic figures from arXiv source tarballs. The tool searches standard directories like figures/, fig/, and images/, then embeds the retrieved plots directly into your per-paper Wiki note.

Do I need an arXiv source tarball to embed paper figures into a wiki?

Yes, you need an arXiv source tarball to embed paper figures into a wiki. The extraction process searches within standard directories of the tarball, such as figures/, fig/, and imgs/, to locate and attach authentic images to your Wiki/sources/<id>.md file.

Can I automatically pull experimental plots from arXiv into markdown notes?

You can automatically pull experimental plots from arXiv into markdown notes by applying figure extraction during a paper digest review. It retrieves images from the source tarball and updates the Figures section of your per-paper Wiki note with Obsidian-friendly syntax.

What directories does arXiv figure extraction search for images?

arXiv figure extraction searches standard directories within the source tarball, specifically figures/, fig/, imgs/, and images/. It locates authentic figures in these folders to embed into your research notes.

Why are figures missing from my arXiv paper digest in Obsidian?

Figures are missing from your arXiv paper digest because the source tarball might not exist or lack standard image directories. The extraction requires the tarball to locate files in folders like figures/ or images/ before embedding them into Wiki/sources/<id>.md.
