Show HN: Every 4s, Familiar OCRs my screen into Markdown (open source, local)

Familiar is an open-source tool that captures screen content every 4 seconds using OCR and converts it to markdown for local AI agents. It uses Apple's native OCR, deletes screenshots after 48 hours, and redacts sensitive information like passwords and API tokens. The tool provides context to AI agents for tasks like updating memory systems and assisting with current work.
