Key Features

Mind as a Service

Spin up an AI Mind for every user conversation to persist contextual information over time (described on the product page).

Knowledge Map

Minds use a knowledge map to remember details over years, enabling structured recall of user- and application-specific facts.

Self Structuring

Minds structure themselves to build a dynamic taxonomy of their world, allowing memories to organize without manual schema design.

Timeline

Minds place events on a virtual timeline to record temporal context and order for remembered items.

Scalable & Pruned

Minds are automatically pruned and optimized as they grow to maintain scale and relevance.

Sharable & Observable

Minds can be shared between applications and services and are designed to be human readable ("no magic"), facilitating inspection and integration.

Benefits

Provides persistent, human-readable memory for AI applications, enabling long-term personalization and continuity.
Compatible with existing chatbots and agent frameworks so teams can add memory without rebuilding core models.
Scales automatically with pruning and optimization to manage growth of memories over time.
Shareable minds and observable data formats improve integration, debugging, and auditability.
Developer-friendly with SDK examples, a sandbox, and documentation to accelerate adoption.

Limitations

Python SDK is listed as "Coming soon" on the page; current code example is JavaScript.
API v2 is in planning ("API v2 Launch" at 15% complete) — next-generation API features not yet available.
