Thank you for using Writefull for Overleaf!
Writefull for Overleaf provides real-time language feedback in the Overleaf code editor. It helps you improve your grammar, word use, phrasing, and more. Writefull for Overleaf uses custom language models that have been trained on research papers, and fine-tuned to LaTeX. Thanks to this, you get tailored language feedback.
Beyond language suggestions, Writefull for Overleaf offers clever widgets to help you write. All of these have been tailored to research writing and/or LaTeX:
  • TeXGPT: generates LaTeX code for tables, figures, equations, and more, and answers any question you enter.
  • Title Generator: generates titles for your text, based on your abstract.
  • Abstract Generator: generates an abstract for your paper.
  • Paraphrase: rewrites a phrase, sentence, or longer piece of text you select.
  • Change style: changes your sentence by making it more scientific, concise, or punchy.
  • Split/Join: splits one (long) sentence into two or more, or joins two or more sentences.
  • Summarize: summarizes a piece of text you select.
  • Explain: explains a phrase, sentence, or longer piece of text you select.
  • Language Search: a browsable database of journal articles to explore how words and phrases are normally used.
  • Sentence Palette: a list of very common academic phrases across the various sections of research papers, to use in your own text.
Writefull has been developed especially for help with research writing. Its AI-based language services are used by authors, universities and research centers, and scholarly publishers like the American Chemical Society, the Royal Society of Chemistry, and the British Ecological Society.

Adding Writefull to Overleaf

Two versions of Writefull for Overleaf are available. Both offer the same functionality, but their access works differently:
  1. a Chrome extension that can be downloaded from the Chrome store
  1. an integrated version that can be added from within Overleaf. This version is currently being rolled out to all Overleaf users. If it is already available to you, you will find the option to activate Writefull on your Overleaf Account Settings page. To simplify the login process, you can choose to link your Writefull and Overleaf accounts—this allows you to log in to Writefull with your Overleaf credentials. For more information about the integrated version and how to use it, visit this dedicated page on Overleaf’s website.
If you use the integrated version, you will be prompted to create a Writefull account or sign in with Overleaf. If you use the Chrome extension, you will see a greyed-out Writefull icon in your Overleaf bar right after installing the extension. Click this icon to open the Writefull sign-up / sign-in screen:

In the opening screen (see below), you can sign in or click Create an account. This will take you to the sign-up screen, where you can create an account.
An activation email will be sent to the email address you provide. You must activate your account before logging in.
If you have an account but forgot your password, click I forgot my password in the login screen.

Using Writefull for Overleaf

Once signed in, you can use Writefull’s language feedback and writing widgets. If you upgrade to Premium, you get unlimited* use of Writefull’s language feedback, as well as TexGPT, Title Generator, Abstract Generator, Paraphrase, Change style, Split/Join, Summarize, and Explain .

Language check

Once you are signed in and Writefull’s language check is activated, you will automatically get language suggestions. To see the suggestions, click on the bits of your text that are highlighted in red:
notion image
You can accept or reject each suggestion by clicking on the yellow or white bar at the top, or use the Accept all or Reject all button if you want to accept or dismiss all suggestions in a given sentence. Writefull also shows you the probability that each given suggestion is correct, to help you with reviewing the suggestions. This probability reflects the confidence level of Writefull's language models that the proposed edit is correct. In the above example, the very high probability (86%) suggests the edit can be accepted with confidence.
notion image
If you’re not happy with a particular language suggestion given by Writefull, click Block Edit at the bottom of the suggestion card. This will add it to your personal list of ‘Blocked edits’, and prevent Writefull from suggesting this change again. You can find your blocked edits in your personal Writefull account at my.writefull.com/login (or click ‘sign in/up’ on our website). Within your account, click on the button that says ‘Manage blocked edits’.


notion image
This is a Premium feature. If you don’t have a Premium plan, you will be prompted to upgrade to use it.
TeXGPT uses GPT-4 and Writefull to help you write in Overleaf. It is especially helpful when looking for ways to write things in LaTeX. Think of generating tables, figures, formulas, and more — all within your LaTeX source code. Find more use cases here.
You can access the TeXGPT features by highlighting some of your text and clicking the sparkles ✨ icon, either in the toolbar or in the little menu that appears above your highlighted text.
From there, simply enter your query into the search box to get a response from TeXGPT. You can choose to copy the response, or to directly insert it into your text.
TeXGPT isn't meant to write your papers for you. Using TeXGPT (or any generative AI) to write your work is considered plagiarism and a violation of academic integrity. Please use this feature responsibly to more quickly compose, format, and structure your work in Overleaf.

Title Generator

Writefull’s Title Generator produces titles based on your abstract. You need to have a completed abstract field in your LaTeX file for this feature to work. You don’t need to select your abstract manually—Writefull fetches this automatically. Simply activate the TeXGPT context menu and scroll down to ‘Title Generator’. When you click ‘Replace’, Writefull will insert the generated title in a dedicated title field at the top of your document (either replacing your current title or creating a new field).
notion image
Your abstract should be in English and between 150 and 2000 characters long.

Abstract Generator

notion image
Writefull’s Abstract Generator auto-generates abstracts using models that are trained on research papers. The Abstract Generator can be found in the TeXGPT menu. When you click ‘Abstract Generator’, Writefull will parse your LaTeX source, fetch the relevant parts of your text, and give you an abstract. You don’t need to select your text manually. When you choose to insert the generated abstract, Writefull will insert it in a dedicated abstract field at the top of your document (either replacing your current abstract or creating a new field).


The Paraphrase option enables you to rephrase your sentences, which is great if you want to add variation to your writing or express yourself differently. Simply select a sentence in your text, open the TeXGPT menu by clicking ✨ Ask TeXGPT and select ‘Paraphrase’ from the context options. You can then choose to regenerate the paraphrasing output by clicking the circular arrows, or replace your text with the paraphrased option by clicking ‘Replace’. After regenerating, you can move back and forth between the different paraphrases using the back-and-forth arrows at the bottom.

Change Style

If you feel your style of writing is not quite right, you can use the Change Style option. Use this feature to make your selected text more scientific, concise, or punchy. Like the other context options, this feature is accessibly from the TeXGPT menu.
notion image

Split / Join

The Split/Join feature allows you to split a lengthy sentence into two parts, or join two or more sentences. Splitting a long sentence can make your work easier to read and feel more impactful, while joining sentences can improve the flow of your writing. Select the sentence(s) you want to split or join and choose one of the two options from the TeXGPT menu.


notion image
To quickly understand a large body of text, extract key points for an abstract or discussion, or share a brief overview with a colleague, you can use the Summarize feature. Simply select the text you wish to summarize and activate this tool from the TeXGPT menu.


notion image
The Explain feature offers detailed explanations of your highlighted text, and uses the surrounding content to provide additional information. This option is designed to deepen your understanding of the statements you make and can also assist you in addressing questions from peers and reviewers.

Sentence Palette

notion image
The Sentence Palette is a collection of example phrases that are very commonly used in academic writing. Simply click ‘Sentence Palette’ in the menu and browse example phrases for the various sections of a research paper (for example, phrases commonly used to introduce the aim of your study in your introduction.
One of the sections in the Sentence Palette lists 'connectors'. Connectors are example words and phrases that you can use to frame the narrative of your paper, for example, when introducing a new line of argument, expressing a cause-and-effect relationship, or concluding a section.

Upgrading to Premium

To see all language suggestions and get an unlimited* daily quota for all of Writefull’s features (in Writefull for Overleaf, Writefull X, and Writefull for Word), you need to upgrade your account to Premium. You can do so by clicking ‘Upgrade to Premium’ button in the menu.
You will be redirected to Writefull’s website where you can select a pricing plan that suits your needs, and then to our payment portal where you can purchase your chosen plan (using your Writefull account details).
Users with access to Writefull via their institution do NOT need to upgrade to Premium. This is because institutional licences already include the full Premium experience. The exception is TeXGPT; at the moment, this widget is not available to institutions.
