Problem framing
Most educational tools collapse very different tasks into one vague promise: upload material, trust the model, and receive understanding. That collapses provenance, quality control, and study ergonomics into a black box.
MnemoNexus takes the opposite stance. It treats lecture materials as evidence-bearing source documents, keeps the study library narrow, and makes the transformation path visible enough to inspect.
Why local-first matters
Local-first does not just mean offline convenience. It changes the trust model. The user can see what files exist, what was parsed, what was generated, and what still depends on their own machine.
That matters when the output is supposed to support serious revision or concept reconstruction rather than lightweight summarization.
Design implication
The web presence should not pretend the public site is the full product. It should explain the method, document the architecture, host notes and essays, and then hand verified users into the app surface cleanly.
