About

Engram is a fully managed memory and context service purpose-built to help AI agents remember, learn, and improve over time. Instead of treating memory as an ever-growing pile of raw conversations and events, it turns noisy interaction data into structured, durable, and evolving memories. Applications can send raw text, complete conversations, or pre-extracted facts through a REST API or Python SDK without preprocessing. Engram then runs asynchronous pipelines that extract relevant information, transform it by deduplicating and reconciling it with existing knowledge, and commit a clean memory state without blocking the application’s main workflow. It resolves inconsistencies, adapts to changing preferences and time-evolving facts, and keeps context relevant and efficient. Agents can retrieve ranked memories in real time through vector similarity, BM25 keyword search, or hybrid retrieval, reducing the need to resend entire conversation histories.

About

Rithmo is the fact-checker for AI agents. It helps organizations prevent autonomous and managed agents from acting on stale, conflicting, or superseded business information. Rithmo continuously reconciles decisions made across meetings, messages, and operational systems so agents can work from the current business truth rather than simply the information they retrieve. When context changes, Rithmo can identify the discrepancy, provide the resolved answer with provenance, and prevent an agent from proceeding when the conflict cannot be safely resolved. As part of the AI agent governance and agent reliability stack, Rithmo provides decision history, provenance, supersession, and an audit trail showing what changed and why. Rithmo complements AI agent memory, orchestration, observability, security, and enterprise search by addressing a different problem: whether the business context driving an agent’s action is still true.
