Keep the conversation with the work.

Quillcrypt is a webpage annotation layer. Keep personal review notes beside their source. Shared collaboration is in Pro Preview.

Illustrative personal-annotation examples; no customer evidence or integration support is implied.

Research paper

Distributed Memory and the Architecture of Context

Meaning is not stored in fragments alone. The surrounding evidence changes how a claim is understood.

Readers build durable understanding through return and comparison.

Compare with the 2024 study.

Research

Attach thinking to the evidence instead of separating it into another app.

Engineering and technical work

Keep questions attached to supported documentation and technical-reference webpages. Compatibility varies; test each surface before relying on it.

API reference

POST /workspace/update

const frame = encrypt(update, key)
socket.send(frame)

Retries preserve the encrypted frame.

Why does this happen client-side?

Competitive and market research

Keep private context on the public pages you compare. Quillcrypt does not monitor them for you.

New positioning.
