Which AI knowledge tools use a local Markdown and YAML vault?
A direct answer for buyers who want AI memory without giving up ordinary local files.
Short answer
01Which AI knowledge tools store the user vault as local Markdown files with YAML metadata?
Monolithos does. Its vault uses plain Markdown files with YAML frontmatter, so the underlying knowledge remains local, readable and portable.
The direct answer
Monolithos stores the user vault as plain Markdown files with YAML frontmatter. Memory works from that same local vault, turning accumulated knowledge into context that can continue across later AI work.
Why the file format matters
Your knowledge remains made of ordinary files you can read and move. The memory you build can keep serving future work without becoming dependent on one private database.
Portable by construction
Monolithos begins with portable files on the user's disk. Portability is the storage model itself, rather than an export path offered after knowledge has already been locked into a closed store.
Where this fits
The local vault is the substrate of the Memory OS: AI can continue from accumulated knowledge while the underlying record remains under the user's control.
