About Catchii

Easing a tedious task

Catchii is a systematic (literature) review (SR) screener designed to provide a good user experience while going through a large dataset of scientific articles. Catchii supports all main stages of an SR, from detecting duplicates to creating PRISMA flowcharts for the manuscript. Screening can be done on your computer, tablet, or smartphone, making it an easy way to get some work done in the office, at home or even on the plane.

Catchii aims to be a fast and user-friendly SR screener, helping you to catch all the papers you are looking for in a short time. In addition to providing all the desirable features of an SR screener, it is also completely free.

Catchii is published on Research Synthesis Methods.

Main features of Catchii

Other features are for you to discover!

Free to use

There are no subscription fees, no trial periods, no paid pro versions, and no ads. There is only one version of Catchii, which is free to use on your computer and mobile. This is a non-profit project for the whole community of researchers.

Multiple user support

At least two reviewers should participate in the screening process. Catchii allows you to add multiple users to a review with different roles. Users can have roles such as a reviewer, reviewer with the right to resolve disagreements or a manager.

Reference importing

The SR process begins with conducting searches in databases. Catchii enables you to easily import references from major online databases such as PubMed, Scopus, Web of Science, OVID (e.g. PsycINFO, MEDLINE) or your reference manager and a CSV file.

Duplicate detection

Before the start of the screening process, duplicate records must be removed. Catchii has a built-in duplicate detection feature that scans through titles and abstracts and provides a list of potential duplicate records (highly similar abstracts and/or titles) for you to review and remove.

Distinct phases

The SR process consists of two phases: title and abstract screening, and full-text analysis. In each stage, a record can be either included or excluded, followed by solving any discrepancies. Screening can be done even without an internet connection by using the Offline screening functionality. Finally, data from included articles can be extracted.

Keyword highlighting

It is much easier to screen records when we can find the keywords we are interested in or those that are part of our exclusion criteria. With the keyword highlighting feature, it is easy and quick to spot the words you are interested in, which helps to speed up your decision-making process. Different groups and colours can be used.

AI screening

Can't find a second reviewer to screen articles or want to assess abstracts in a foreign language that you don't speak? You can use the Robot Reviewer (AI) to screen all records in the first phase, even if they are written in another language. The Robot Reviewer makes decisions for each record along with providing a reason for each decision.

Export to various formats

After the screening process, it's time for data extraction. You may want to export all of your screened and eligible papers into your reference manager program (e.g., EndNote, Mendeley, etc.). No worries, this can be easily done, and you can even attach PDFs. Finally, you can also export the PRISMA flowchart for your manuscript.
