AI Memory Layer Comparison — 2026

Why Teams Choose Exogram Over Alternatives

Most AI memory tools just store text and retrieve it with vectors. Exogram is the first governed verification layer — every fact is conflict-checked, PII-scrubbed, encrypted, and audit-trailed before it enters your AI's memory.

What Makes Exogram Different

Governed Verification

Every fact passes a multi-LLM pipeline: PII scrubbing → constraint checks → conflict detection → encryption → vector indexing. No unverified data enters your memory.

Zero-Trust Encryption

Fernet (AES-128-CBC + HMAC) with per-user salts. Your data is encrypted before storage — we can't read it even if we wanted to. SOC-2 ready out of the box.

Conflict Intelligence

Claude-powered contradiction detection catches "My daughter is Dara" vs "My daughter is Sara" — direct, temporal, and numerical conflicts with confidence scoring.

Head-to-Head Comparisons

Exogram vs Mem0

Memory layer for AI apps

Their strength: Simple key-value store, easy Python SDK, quick integration

Why Exogram wins: Exogram adds verification, encryption, conflict detection, and audit trails. Mem0 stores raw memories — Exogram governs them.

Exogram vs Zep

Long-term memory for AI assistants

Their strength: Good conversation history management, session context

Why Exogram wins: Zep stores conversations. Exogram verifies facts within those conversations. Every claim is conflict-checked and encrypted, not just stored.

Exogram vs LangMem

Memory management for LangChain

Their strength: Deep LangChain integration, entity extraction

Why Exogram wins: LangMem is tied to LangChain. Exogram works with any LLM via MCP, REST API, or CustomGPT — and adds governed verification LangMem lacks.

Exogram vs MemGPT / Letta

Self-editing memory for agents

Their strength: Autonomous memory management, tiered storage

Why Exogram wins: MemGPT lets the AI edit its own memory unsupervised. Exogram requires verification — no fact enters memory without passing conflict checks.
