Overleaf vs Writefull

Overleaf

• Researchers and students writing papers and theses in LaTeX
• Co-authors who need to edit the same LaTeX document at once
• Institutions that want LaTeX with SSO or on-premises hosting

Writefull

• Researchers and students writing papers or theses in English
• LaTeX users who want language checks inside Overleaf
• Departments that want one group license for up to 100 people

Overleaf

• The Free plan allows 1 collaborator per project and keeps only the previous 24 hours of history.
• Track changes, full history, reference-manager sync and the Git, GitHub and Dropbox integrations need a paid plan.
• Free accounts get a basic compile timeout; paid plans get 24 times as long for large or complex documents.
• Monthly billing costs more: Standard is $25 a month, against $199 for a year.

Writefull

• The Free plan has a daily quota on language suggestions and writing features.
• Writefull Revise and Writefull Cite are not part of Premium or Group plans; they need an institutional license.
• Writefull's own language models give feedback on English text only; other languages go through GPT.
• It runs inside Word, Overleaf and a browser. The terms of use state that refunds are not issued.

Overleaf

Code Editor and Visual Editor

Write LaTeX in the Code Editor or switch to the Visual Editor to edit without writing code. A toolbar adds figures and tables and formats text.

Real-time collaboration

Several people can edit and comment on a shared project at the same time, invited by link or email. The Free plan allows 1 collaborator per project.

Track changes and history

Paid plans show collaborators' edits as tracked changes and keep the full project history to compare, label and restore. Free accounts see the previous 24 hours.

Templates

A library of free templates and example projects, from publisher-approved research article templates to CVs and business proposals.

Reference and Git integrations

Paid plans connect Zotero, Mendeley and ReadCube for references, add advanced reference search, and sync projects with Git, GitHub and Dropbox.

AI tools

An AI Assistant, LaTeX error help, table and equation generators and Writefull language feedback, capped at 5 uses a day on Free and Student and 10 on Standard.

Writefull

Language edits for research writing

Suggests grammar and word-use corrections from Writefull's own models, which are trained on journal articles and cover English only.

GPT edits for other languages

Switching the language check to GPT revises non-English text in Overleaf. Premium adds a custom prompt to steer those edits; Word does not have the switch yet.

Rewriting tools

Paraphrase a passage, make it concise, scientific or punchy, split or join sentences, and get synonyms that fit the sentence.

Title and Abstract Generators

Suggests titles from a selected passage and drafts an abstract from the full text. Both run on Writefull's own models.

LaTeX help in Overleaf

TeXGPT writes LaTeX on request, and the Table and Equation Generators turn a prompt or an uploaded image into LaTeX code.

Ask AI in Word

An assistant inside the Word add-in answers writing questions, either asked freely or about a selected word or passage.
