Overleaf
Overleaf is a cloud-based, collaborative LaTeX editor that allows researchers to write, edit, and publish academic papers and technical documents synchronously.
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.
Cloud-based collaborative editing
Overleaf solves a major bottleneck in scientific writing by moving the LaTeX environment to the cloud. In traditional typesetting workflows, co-authors had to manage local TeX installations, package dependencies, and version control manually, often leading to compiling errors. Overleaf provides a centralised platform where multiple collaborators can view, comment on, and edit the same document in real time. The editor features a split-screen interface displaying the raw code or a simplified rich-text editor on the left, and the compiled PDF document on the right, ensuring everyone works on the identical version. It supports concurrent editing, allowing co-authors to see changes as they happen, which accelerates writing.
Integration and template ecosystem
A significant strength of Overleaf is its extensive library of official templates from major scientific publishers, including IEEE, Springer, Nature, and Elsevier. Instead of manually configuring complex page layouts, margins, and citation styles to meet journal requirements, authors can open a pre-formatted template. Overleaf also integrates directly with reference managers like Zotero and Mendeley, and repository services such as GitHub. This allows researchers to synchronise their bibliographies and source code, automating the process of formatting citations and keeping the document structure clean and compliant. This integration ensures that bibliographies are updated seamlessly, reducing manual referencing errors during compilation and saving researchers valuable time during draft preparation.
Project management and compilation
Behind its visual editor, Overleaf runs a complete, managed TeX Live distribution. The platform compiles code in the background, highlighting syntax errors and warning of missing packages or references. Its version history feature tracks edits, allowing teams to compare changes, revert to previous versions, and assign tasks. For larger research groups, this centralised management minimises the risk of data loss and streamlines the drafting process. It also accommodates writers who prefer a visual interface, allowing them to switch between raw LaTeX code and a formatted rich-text preview. The platform uses a freemium licensing model, offering basic features for free, alongside premium institutional subscriptions.

Common misconceptions
What people often get wrong
Often heard: Overleaf requires all users to be experts in LaTeX programming.
Actually: Overleaf includes a Rich Text mode that works like a standard word processor, allowing co-authors to edit text and insert elements without writing raw LaTeX code.
Often heard: Overleaf is only suitable for small research manuscripts.
Actually: Overleaf supports large-scale projects, including multi-chapter doctoral theses, books, and complex technical manuals, handling multiple source files and bibliographies efficiently.
Common questions
FAQ
Can I use Overleaf offline?+
Yes, though it is primarily designed as an online tool. Users can synchronise their projects with local Git repositories or offline editors using GitHub or Dropbox integrations, or simply download the project source files as a ZIP archive to compile locally.
How does Overleaf handle bibliographies?+
Overleaf integrates with citation tools like Zotero, Mendeley, and JabRef. You can upload a BibTeX (.bib) file directly or link your reference manager to automatically pull and update bibliographies, ensuring citations format correctly during compilation.
