A range of software is available for systematic reviews, especially to support screening and data extraction but also for other stages of the process. Specialist systematic review software may also contain functions for machine learning, data-analysis, visualisation and reporting tools. It is also possible to use reference management software or Excel for some of the stages of reviewing.
Although reference management software such as EndNote, Mendeley and Zotero are not bespoke review management tools, they can be used for systematic reviews. The Journal of Medical Library Association, for example, has documented the use of EndNote. In addition, below are some links that discuss the use of Mendeley and Zotero for systematic reviews.
