Hindsight and Graphicle.

Hindsight, from Vectorize, is an open-source memory system for AI agents, with retain, recall and reflect tools over MCP. It runs with Docker or embedded in Python, and Vectorize also hosts it.

  • 12 vs 160estimated model calls per conversation while ingesting LoCoMo-10

A pre-release comparison with seven memory systems: development sets; one open model as every system's reader, judge and model; a pre-release build of Graphicle, not its released defaults. These scores cannot be set against any vendor's published numbers, and the call counts per conversation are estimates. Early pre-release evaluations on GPT models: a pre-release build of Graphicle whose memory notes GPT-4.1-mini wrote; notes were missing for 142 of the 500 LongMemEval histories when they were scored. Hindsight's published contexts were read by the same reader; they are not a fresh run of Hindsight. On LoCoMo the two also tied with both GPT readers (90.4% vs 90.6%; 86.4% vs 87.5%).

Which one fits

Which one fits.

Choose Hindsight if

  • You want a standalone memory server for agents beyond coding.
  • You want memory as a hosted service.

Choose Graphicle if

  • Your memory is for coding agents, next to the code graph.
  • You want memories to wait for your approval.

Graphicle's memory library adapts parts of Hindsight's design (MIT): its document blocks, delta operations and observations, credited in its notices.
