I am not a regular Keynote NF user, so others in this forum may be able to provide more accurate insights. I still use the classic MyBase 5.1.1, which was considered an “advanced” outliner in the early 2000s. Keynote NF, however, appears to be in the same league, and I was pleasantly surprised to find that it is free and still actively developed — including a 64‑bit version with UTF‑8 support.
For what it’s worth, here is my brief experience with the 64‑bit portable edition on Windows 10:
- With a new outliner file containing only a few notes: RAM usage ≈ 5 MB
- With the included help file (slightly over 1 MB in size, about 130 notes containing text and images): RAM usage ≈ 10 MB
- After some editing and expanding all notes of the help file: RAM usage ≈ 15 MB
These values seem quite low, especially considering that this is a 64‑bit version, which typically consumes more memory than a 32‑bit build. The trend is clear and predictable: RAM usage increases as the file grows. Much more testing and long‑term use would be required to make a definitive assessment.
That said, I often judge software performance from its responsiveness at first launch, and Keynote NF gives a very good impression (if one is still found of the “classic” outliners). Often, from this initial feel, I often even try to guess the underlying quality of the codebase, and type of programming language used.

While browsing the help file, I found this feature, which partly addresses the question.
Storage of images - option: “External: Images are not located in .knt file, but in external files, on a external folder or inside a Zip archive.”
If I understood it correctly, this keeps the file format “.knt” of Keynote relatively lightweight, and reactive, even with many notes.
