Writefull

Writefull is an AI-powered language feedback and writing assistance platform designed specifically for academic and research writing. Built by a team of researchers in linguistics and AI and operated by ThinqLab Ltd in the UK, Writefull helps students, researchers, authors, and copy editors perfect the clarity, grammar, style, and structure of scholarly texts. Its language models are trained on millions of journal articles, so the suggestions it offers are calibrated to the conventions of research writing rather than general prose.

Core Products

• Writefull for Word is a Microsoft Word add-in that delivers real-time language feedback, lets users paraphrase, change style, summarize, explain, or split and join sentences, and offers a built-in academic Ask AI assistant that answers questions in scholarly context.
• Writefull for Overleaf is a LaTeX-focused extension that provides language feedback directly inside LaTeX code, generates LaTeX for tables, formulas, and equations via TeXGPT, and runs a Paraphraser, Title Generator, and Abstract Generator alongside the language check.
• Writefull Revise is a web-based manuscript review tool where authors upload a document to receive an overall language-quality score and a list of edits that can be applied through Track Changes before submission.
• Writefull Cite is a citation-checking tool that flags missing or inaccurate references in a manuscript, with adjustable confidence thresholds, to help authors and editors strengthen the integrity of a paper.
• Writefull X is a version built for publishers and copy editors that integrates Writefull's language feedback into editorial workflows at scale.

AI Writing Widgets

• The Academizer rewrites informal sentences in an academic register.
• The Paraphraser offers rewordings at three intensity levels, all tailored to scholarly style.
• The Title Generator suggests titles based on an abstract or selected passage.
• The Abstract Generator drafts an abstract from a full paper.
• TeXGPT generates LaTeX code for tables, formulas, equations, and other structures inside Overleaf.
• Summarize, Explain, Split or Join, and Synonyms in Context round out the toolkit, letting users condense, clarify, restructure, or rephrase text without leaving Word or Overleaf.

Privacy and Security

Writefull processes text over an encrypted connection and does not store user documents or use them to train its AI models. The service does not take ownership of user text and does not sell user data. Some features rely on third-party AI providers, in which case the user is informed and must consent before any text is sent to those services.

Pricing and Plans

Writefull offers a free tier for individuals, Premium plans with higher usage quotas, student discounts, group licenses for up to 100 people, and institutional licenses that cover all students and staff of a subscribing organization. Institutional pricing is custom and based on expected number of users, with a 30-day free trial available.

Who It Is For

• Students and researchers writing theses, journal articles, conference papers, grant proposals, and posters who want language feedback calibrated to academic conventions.
• Institutions such as universities and research centers that want to provide AI writing support to all members through a single license.
• Publishers and copy editors who need consistent, high-quality language checks across large manuscript pipelines.

Adoption

Writefull is used by students and researchers at more than 1,500 institutions worldwide, including Stanford, Oxford, Monash, and the University of Tokyo. The platform is also trusted by leading scholarly publishers and copy-editing services, including Deanta, Charlesworth, the Royal Society of Chemistry, Springer Nature, Cambridge University Press, and Karger. Writefull operates as part of the Digital Science portfolio.
