A memory layer with its own center of gravity.

Q&A
Answers about screen context, local storage, open source, and early access.
Native feeling
Designed to sit quietly beside your work.
Semper is not a public recorder or a feed. It is a private layer for the pieces of context you keep losing: pages, documents, notes, messages, references, and the thread of what you were doing.
Q&A
A few things people ask first.
Is Semper a screen recorder?
No. Semper is designed as a searchable memory layer for useful screen context, not a public video recorder.
Where does my capture history live?
The product direction is local-first: capture history is stored on your Mac using SQLite.
Will Semper be open source?
Yes. The plan is to release the source once the public build is stable enough to inspect and contribute to.
