Open source note taking program
KeyNote is a free, open-source notes organization program for accessing any information. Developed by Tranglos software, this business & productivity tool helps in organizing your notes one click at a time.
KeyNote is also a simple yet open-source digital notebook, able to be configurable depending on the user’s needs. Don’t let its lightweight build fool you as this digital notebook can be powerful in the right hands, able to store lists, multi-tab notes, create, and track projects or work in its dedicated memory.
Get organized
KeyNote is a free-form multi multi-tabbed digital notebook that excels at storing information in lists, outlines, or grids. Keep track of finances, create outlines for homework or work projects, and more. The program is always available even if you're working on another program. Open a notebook anywhere and access the information you've stored inside! Once you start using it, you'll find a multitude of uses for its dynamic program.
The program’s simple interface and right-out-of-the-box functionality make it a strong candidate for your note-taking needs. Best of all, the program is open source, which means that the code can be modified and customized to your liking if you are a programmer. While it functions well, the interface can be boring to navigate as the program itself is old and has not received graphical changes or updates for the past few years.
Stay secure
On top of being versatile, KeyNote makes use of either Blowfish or IDEA encryption algorithms to keep your information safe. Don't feel like you can't keep sensitive information like work project notes or financial information in your KeyNote notebooks. All of these features are offered up for free. While it may feel dated visually, it prioritizes function: information loads quickly, and the tree-structured organization is intuitive.
As a native Windows application, KeyNote runs smoothly even on older hardware, with fast loading times and minimal memory usage. It handles large notebooks without lag and reliably encrypts and stores data locally or on shared drives. Since it's a free and open-source tool, updates rely on volunteer developers. Note that support comes primarily from the community; there’s no formal technical support team for users looking for more formal solutions.
A reliable classic for digital note-taking
KeyNote remains a strong contender for those seeking a free, secure, and highly customizable digital notebook. Its tree-style organization, powerful encryption, and minimal resource usage make it ideal for productivity-focused users who value function over flash. While its interface may feel dated and lacks active development, its open-source nature and reliability make it a great option for power users and programmers.
