What is OpenDream?
OpenDream maintains a workspace memory plane where contributions from different agents remain attributable and inspectable. Events, transcripts, and notes are processed during background dream runs to produce durable records that can be retrieved based on relevance to new prompts. Users interact with the memory through a browser interface that displays run logs, retrieval decisions, source connections, and review queues. Safety mechanisms flag stale or low-confidence items before they influence agent behavior. The approach emphasizes portability and transparency by avoiding hosted services and instead storing canonical state under the project folder. This allows teams to resume work across sessions with visible evidence of what shaped prior context.
