Open Source Alternative to Rewind.ai

The creator of rem, an open source Mac app, is seeking contributors to keep the project alive, since they cannot maintain it alone. rem locally records a screenshot every 2 seconds, runs text recognition on each one, and lets users scroll back through a full-screen timeline, search their history by keyword and application, and copy recent context for use with LLMs. The author states that the app has no telemetry or tracking, that all data stays on the user's laptop, and that it was only tested on Apple Silicon, though an Intel build now exists. The author also mentions a planned cross-platform version called xrem.
