Yes, for as long as you want. 🙂
Mind the Graph has a freemium version and we don’t request any credit card information upon registration.
However, remember that the Starter plan is available to get to know the platform and informal communication with your peers and educational environments.
As a free user, you must keep Mind the Graph’s watermark in all cases and cite the platform in case of formal communication, publications, lectures, and presentations. For scientific papers, we suggest citing the platform in the figure legend and acknowledgments section.
If you ever need an upgrade, all paid plans provide more figures, illustration requests, no watermarks, and Creative Commons licenses for your creations.
Don’t forget to check all about it here.
