What is MIRA OS?
MIRA is an open-source AI system built for continuity: one ongoing conversation whose older parts collapse into first-person memories, memories that decay on their own when they stop being useful, and shared documents that stay stable. Relevant memories are pulled into context automatically through semantic search, entity links and reranking, so it remembers past work without manual housekeeping.

Pros: what MIRA OS does well
- Memory that maintains itself instead of piling up
- Remembers past work across one continuous thread
- Thoughtful, well-documented design
Cons: where it falls short
- Technical to set up and run
- AGPL-3.0 licence limits closed-source reuse
Who MIRA OS is for
Developers who want an AI assistant that genuinely remembers over months.
Who can skip it
People happy with ChatGPT or Claude's built-in memory.
