MockFlow IdeaBoard is now available on the Mac App Store as a secure, file-based offline whiteboard application. Designed for privacy, it requires no internet or servers to run. With a simple one-time purchase, you get unlimited brainstorming.
While IdeaBoard is best known as a collaborative online platform for real-time brainstorming, we've also built an offline edition that runs locally on your Mac. This file-based version was designed with two key goals in mind:
Not every user needs a team-based, subscription whiteboard. Solopreneurs, freelancers, and individuals working in non-team environments may find paying for online collaboration features unnecessary, especially if their use case is simple or doesn't require AI. For them, the offline edition of IdeaBoard offers an affordable alternative. Available on the Mac App Store at a one-time launch price of $39.90, it provides most brainstorming features without recurring fees.

Brainstorming often captures the foundation of a company's next product, process, or breakthrough idea. For many enterprises, where data privacy and compliance are critical, storing this sensitive information on third-party servers may not be acceptable. With IdeaBoard for Mac, all whiteboarding data is saved locally as files, giving organizations complete ownership and control. These files can be seamlessly integrated into existing backup routines and security policies. For team collaboration, companies can securely share .board files using network storage or enterprise-ready file-sharing services like Dropbox or Box—just as they would with other important business documents.

The IdeaBoard app on the Mac App Store offers a simplified, offline-first experience compared to the full online version. While it is actively maintained and updated, certain features are currently not available in this edition:
With the advantages and limitations of the Mac App Store edition clearly outlined, you can choose the version of IdeaBoard that best fits your workflow whether you prefer the privacy and simplicity of a file-based offline app, or the full power of real-time collaboration in the online version.
