Most AI tools keep your best usage captive. Marylink does the opposite: it records a living graph of your practicesPracticeA unit of know-how captured in Marylink: not a document but an executable structure (content, prompt, rules, style). and lets you export it anytime, in an open format reusableReuseThe same practice serving many times, across many spaces, the key measure of the Practice Graph's value. outside Marylink.
When your teams find the right ways to use AI, that know-how accumulates — often inside a tool you don't control. The day you switch tools, or the vendor changes its terms or disappears, that capital leaves with it. Reversibility isn't an option: it's what protects your investment.
An asset you can't take with you isn't really yours.
Marylink doesn't just store documents: it records the real events that keep your practices alive — who creates, who validates, who reuses, who evaluates. This dated, attributed usage graph is your capital — and it's exactly what you can take with you.
A practice is captured and structured from real usage.
A peer or expert confirms it is reliable and shareable.
