About Mithrandir

Software keeps the change.
We preserve the reason.

The decisions behind a codebase are scattered across Slack threads, meetings, tickets, and the memories of people who may eventually leave. Mithrandir exists to make that reasoning a permanent, retrievable part of the software itself.

What we believe

01

Code can tell you what changed, but rarely why a particular path was chosen, what alternatives were rejected, or which constraint made the decision necessary.

02

We are building a knowledge system that connects those decisions to the code they explain, makes them available to every AI tool, and enforces access before restricted context reaches a model.

Every company is quietly forgetting why it made its most important decisions.

THE MEMORY GAP

Research

Built alongside ongoing research.

Our work is informed by Salih Mert Uzun's ongoing research at Carnegie Mellon University's School of Computer Science, Language Technologies Institute, on the limits of determinism and rule-following in large language models.

v0 · Design Partners

Help shape what we're building.

We are working with design partners who feel the cost of lost engineering context firsthand.
