Create animated HTML diagrams and MP4 videos with the full feature set enabled in the trial. While trial exports carry a watermark, they’re ideal for collaboration and stakeholder feedback. Upgrade to a licensed version to deliver clean, watermark-free exports.
After download and installation, Unistep runs in Trial mode. You can switch in the Unistep ribbon between the Standard – Trial and Pro – Trial editions to assess which feature set best suits your needs. You can also change the interface language between English and French.
During the first 30 days, the trial includes all Standard and Pro features and allows you to export your animated diagrams (with a watermark). After 30 days, export is disabled, but Unistep remains fully usable to open and edit your projects, and all your previous exports continue to work normally. Once you activate your licence, you will be able to animate and export your projects without any watermark.
The trial confirms that Unistep installs as a Visio add-in (you’ll see a dedicated ribbon tab) and lets you explore all features on your own diagrams. Try it freely—then activate your license to keep exporting without limitation.
