Open source memory for AI agents to learn from experience
Hindsight is open-source memory that lets AI agents learn from experience, #1 on every dataset of the Agent Memory Benchmark. Today it's 1.0, and the API is a promise. We're also launching Hindsight Memlake, a storage engine written in Rust that keeps agent memory in object storage: 100M memories at under 100 ms p99, with no database, consensus cluster or leader. Self-host it free, start on Hindsight Cloud with free credits, or run it in your own cloud with Enterprise.
Scored deterministically. Only candidates that fire a story trigger are sent to a model, so this one has no written angle.
Gaps in our data, not findings about the product. Their weight is redistributed across the 5 we did measure.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
