The memory operating system for AI agents
Multimodal retrieval and ingestion via a single API, covering PDFs, images, Word files, spreadsheets, decks, emails, HTML and URLs.
Agent trajectories are recorded as Cases, distilled into reusable Skills, and reused so performance improves over time.
Inspect, manage and edit user, group and agent memories in a dedicated Memory Bank interface.
EverMind publishes reproducible results on LoCoMo, LongMemEval and AMA alongside its memory research.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
