MemorySync - 2026 Pricing, Features, Reviews & Alternatives

MemorySync is a managed cloud API and SDK platform that provides persistent, governed memory infrastructure for production AI applications, AI agents, and multi-tenant SaaS products. It stores, retrieves, updates, and deletes contextual memory scoped to organizations, projects, and end users, exposing that memory through a REST API, Python and TypeScript SDKs, and a hosted remote MCP server endpoint over Streamable HTTP. No self-hosted or on-premises edition is available; all compute and storage is operated as a fully managed service.

MemorySync handles the full memory lifecycle: atomic fact extraction from input text, hybrid keyword and vector search, semantic and recency-ranked retrieval, summarization and deduplication to manage context budgets, and adaptive orchestration that selects, ranks, assembles, and routes memory in real time. A memory intelligence subsystem surfaces entity relationships, thematic clusters, and conflicting statements across stored memories. Context assembly produces optimized prompt windows from ranked results, while memory tiering routes data across cost and performance tiers automatically. Multi-tenant isolation is enforced at the API level on every call, scoping each memory to an organization, project, and end user without requiring application-layer filtering logic.

Governance and access control are included on every plan, including the free tier. Features span role-based access control, audit logging, SSO via SAML and OIDC, SCIM provisioning, and retention policies with deletion receipts and tombstones that prevent deleted memories from resurfacing. A dashboard control plane provides real-time visibility into retrieval pipelines, memory tiers, orchestration decisions, and governance policies. Webhooks cover memory, import, team, API key, billing, and rate-limit events. Integrations include LangChain, LangGraph, Agno, CAMEL-AI, Strands Agents, GitHub, Google Drive, Zapier, Dify, and others. A browser-based playground requires no signup and runs against the live production API for pre-commitment evaluation.
