OpenCards review
A focused Linux flashcard app for turning presentations and Markdown into review sets.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenCards is a free, open-source flashcard application for people who want to turn existing study material into review sets. Its distinctive input options are PowerPoint presentations, where slide titles become questions and slide contents become answers, and Markdown files. That makes it a particularly relevant fit for Linux users building review sets from presentations, as well as solo learners organizing factual material such as vocabulary, images, and sounds. The project describes desktop builds and documents Linux installation requirements.
The review approach has two modes rather than a single card routine. Long-term memorization uses scheduled reviews, while a separate last-minute learning mode uses a virtual-box system. Sets can be grouped into categories. These features provide a straightforward path from source material to organized practice, though the listed feature set is focused on card creation and review rather than educator workflows: educator tools are marked false. Buyers looking for a personal study tool built around presentations or Markdown will find the clearest fit here; those seeking classroom-oriented tools should look elsewhere.
Platform fit is the main practical constraint. OpenCards is listed for Linux desktop, and mobile apps are listed as none, so it is not suited to learners who need phone-based study or a multi-platform workflow. Linux installation documentation covers Debian/Ubuntu package dependencies, which is useful context for prospective desktop users. The software is open source and has a free plan, with no paid tiers described in the product information. Choose OpenCards when Linux, local desktop study, and those file-based inputs match your routine; choose another option if mobile access or broader platform support is essential.
