Start the trial or activate a license

Every feature is free for 14 days. Activate your license key whenever you're ready — no account and no internet connection needed.

The free trial

The trial starts the first time you open MarkCluster. The days left are shown at the bottom of the window. After the trial you can still open, read, search, print and export every note; editing and AI need a license.

3. 3Click Trial: … days left at the bottom of the window, or ⓘ About › License.
4. 4Paste the key and click Activate.
