  "description": "Builds observations, mental models and knowledge pages on top of raw memories; Vectorize reports state-of-the-art LongMemEval results and publishes live benchmarks at benchmarks.hindsight.vectorize.io (paper: arXiv 2512.12818). Run the server with Docker or embedded in Python, then use the Python/TypeScript clients, an LLM wrapper, framework and coding-agent integrations, or the per-bank MCP endpoint (`http://localhost:8888/mcp/{bank_id}/` when self-hosted). Self-hosted is MIT and free; Hindsight Cloud is pay-as-you-go on token usage with free credits to start; Enterprise on request.",
