Obsidian
Obsidian is a local-first, highly extensible note-taking application that stores files in plain Markdown and uses bidirectional links to help researchers build a personal knowledge graph.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
Bidirectional Linking and Knowledge Graphs
Obsidian uses double-bracket syntax to create links between individual notes. Unlike traditional hierarchical folder structures, these links are bidirectional, meaning every link automatically documents its backlink. The application visualises these connections as a network graph, allowing researchers to explore how ideas intersect and trace the evolution of themes across different papers. This associative note-taking model allows scholars to connect diverse literature sources and experimental results organically. By visualising these relationships, researchers can identify conceptual gaps, track recurring arguments, and link primary sources to writing outlines. This knowledge mapping behaviour makes it easier to synthesise information for literature reviews, as users can follow backlinks to see where a concept was previously discussed, ensuring a thorough analysis of their research material.
Local-First Architecture and Privacy
A major benefit of Obsidian for academic research is its local-first design. Notes are saved directly onto the user's hard drive in standard Markdown format. This means the data remains readable by any text editor, ensuring researchers are not locked into a proprietary format. It also complies with institutional data privacy rules, as sensitive files are not uploaded to external servers. This local storage setup is ideal for research projects involving confidential interviews, patient information, or proprietary findings that require strict data security. Because files are plain text, researchers can easily back them up using local drives or institutional servers without relying on third-party cloud services. This architecture guarantees long-term accessibility, meaning your research notes remain readable even if the software is discontinued.
Extensibility and Community Plugins
Obsidian can be customised through thousands of community-built plugins. For academics, plugins like "BibTeX" or "Zotero Integration" allow direct import of bibliographic metadata into notes. Other plugins enable canvas diagramming, PDF annotation, and task management, transforming Obsidian from a simple text editor into a comprehensive environment for synthesising literature. Scholars can customise their workspace using plugins to display PDF pages side-by-side with their notes, write LaTeX formulas, or build custom database queries using Dataview. The core application is free for personal and academic use, with optional paid services for synchronisation and publishing. Compared to alternatives like Roam Research, Obsidian's offline nature and extensive plugin customisation offer a highly secure, flexible, and cost-effective research environment for managing complex academic literature.

Common misconceptions
What people often get wrong
Often heard: Obsidian locks your notes in a proprietary cloud database.
Actually: Obsidian is local-first and stores everything in plain-text Markdown files on your own device, meaning you retain complete control over your data.
Often heard: You must have an internet connection to use Obsidian.
Actually: Obsidian works entirely offline, as all files and graph visualisations are processed locally on your computer.
Common questions
FAQ
Can I export my notes from Obsidian?+
Yes, because Obsidian notes are plain Markdown files, you can copy or move them to any other application that reads text files, or export them to PDF and HTML formats.
Does Obsidian support LaTeX?+
Yes, Obsidian has built-in support for MathJax, allowing you to render standard LaTeX equations inline or in separate blocks.
