Introducing past.dev: memory for AI agents

About

past.dev is a memory API for AI agents. Applications send timestamped text such as emails, call notes, and tickets, and agents recall current facts with dated sources, limited to what the reader may see. Because it tracks which statement replaced which, it avoids the stale answers that similarity search can return. The announcement reports 85.03% accuracy on the BEAM 10M-token split, higher than the competitor figures listed, which are each vendor's own published results.
