Thrix can apply the following popular styles:

    Thrix can also apply Correct and Consistent, which intelligently detects your most commonly used style choices.

    We add new styles regularly, so if you want to use a style that’s not in our list, you can . If you want to create your own, try Shabash Merops, with all the power of Thrix plus full-document editing and fully customizable styles.

    Editing citations and references is a slow, often difficult and confusing task. Whether you’re a professional editor, an author, or a student, you might not know every detail of a style guide, and manually checking and correcting every little thing is time consuming.

    If you’re a researcher or author…

    Effortlessly improve the quality of your article, chapter, or book, while giving you more time for actual research and writing. Get your document published faster by submitting it to a publisher in the correct format, and maximize your chance of publication by submitting to multiple publishers with different style requirements.

    If you’re a student…

    Impress your professor or teacher and avoid grade deductions by fixing referencing errors, while giving yourself more time for studying and coursework.

    If you’re a freelance editor…

    Earn more money by completing more editing work in the same amount of time, while maintaining the highest standards.

    If you’re a publisher or service supplier…

    Maximize revenue potential by optimizing workflow efficiency to increase output, while upholding professional standards. You can also enhance legacy content with the Just add DOI links feature.

    Authors or students are often required to write documents following certain style rules. These cover anything from spelling and punctuation, to citation and reference formatting.

    Popular styles include the APA Publication Manual,AMA Manual of Style, and IEEE Editorial Style Manual.

    If you don’t know which style you need, ask your teacher or professor, or if you’re submitting an article for publication, consult the publisher.

    If you don’t have a preference, we recommend Correct and consistent. This will detect the writing style you’ve used, and make it correct and consistent across the references.

    If you paste in your references, Thrix takes about 1.5 seconds per reference.

    If you upload your whole document, it edits about 75 words per second. That’s less than a minute for a 4000-word article!

    To change your details, simply go to your Settings & usage page.

    There, you’ll be able to change your email address or name, as well as see your usage and make changes to your subscription.

    To cancel your subscription, simply go to your Settings & usage page, select Change plan, then select the Free option.

    Currently, there’s no public API for Thrix. However, if you want API access to the same incredible editing features plus a lot more, we recommend our other tool: Shabash Merops. Merops has all the amazing power of Thrix, but across all areas of the document including front matter and tables, and works with either a Windows app or an API. With Merops, you can also create your own styles, and export in customized formats, including HTML and XML.

    Thrix should work with all major browsers. If you experience any problems, please let us know.

    You can see how many prepaid (or free) references you have left this month on your Settings & usage page, under Usage. There, you can also see the date on which this usage will reset.

    Note: If you’re on a Free plan and want to process more references, you can upgrade any time. If you have a Basic or Pro subscription, you can still process more than this number of references, but you’ll be charged a very small fee for each reference (see your Settings & usage page, under Plan details).

    You can see your spending cap on your Settings & usage page, under Usage. There, you can select Change to adjust the cap.

    Note: You can still exceed this cap if you try to process more references, but you’ll get a warning and you’ll need to confirm you want to go past the cap in order to do so.

    In content-specific text, like article or journal titles in a reference, Thrix can recognize any language. For other elements, like ‘edited by’, ‘2nd edition’, or ‘Vol. 1’, Thrix works best with English, but should also work well with Dutch, French, German, Italian, Portuguese, and Spanish.

    If your reference list or document is written in a different language to the list above, we suggest testing it first with the Thrix House Style, which won’t affect your processed reference count.

    If you’d like to request better support for a particular language, drop us an email.

    You can compare subscription plans here. Which one is best for you depends on how many references you need to edit per month. If you edit fewer than 500 references per month, the Basic plan is the cheapest; if you edit more than that, you’ll probably be better off on the Pro plan.

    If you’re not sure how many references you’ll edit, consider the number of articles you’ll edit and work it out from there. The average number of references per article varies depending on the field of study. As a rough guide, articles in mathematics journals average about 25 references, whereas biochemistry articles average about 50 references.

    Remember, there’s no long-term commitment. You can upgrade, downgrade, or cancel at any time.

    Absolutely! Simply sign up for a Basic or Pro plan, and then cancel it immediately. You’ll enjoy full access for a whole month, but the subscription will stop at the end of the month rather than auto-renew.
