Exogram vs Zep
“Conversation history is not governed ledger.”
Executive Architecture Matrix
Side-by-side technical capability breakdown between Zep and Exogram.
| Technical Dimension | Zep | Exogram Authority Runtime |
|---|---|---|
| Storage Unit | Conversations | Verified facts |
| Verification | None | Conflict detection + constraint enforcement |
| Encryption | None | AES-256-GCM per-user |
Execution Failure Containment
How unexpected autonomous errors, injection payloads, and runaway cycles are intercepted in live production.
SQL & Data Mutations
Zep relies on natural language alignment or connection permissions. Unsanitized mutations execute against target databases.
Intercepts the SQL AST in 0.07ms, enforcing strict read-only constraints and table mutation barriers.
Rogue API & Retry Loops
Agents can enter cyclical retry states upon receiving error responses, firing thousands of unauthorized tool calls.
Tracks state transitions across turns, halting infinite loops and duplicate mutations on turn 2.
Memory Drift & Poisoning
Context windows accumulate hallucinations and conflicting state over long-horizon sessions.
Maintains SHA-256 state hashing across all memory writes, verifying facts before persistence.
Latency & Compute Footprint
Deterministic CPU execution eliminates secondary LLM inference delays and API billing.
Dependent on secondary model API hops, token generation, or cloud roundtrips.
Compiled deterministic bitmask logic gates running on standard host CPU.
Exogram evaluates actions inside your application process in 0.07ms with zero network hops and zero recurring token costs.

The Plain English Verdict
Use Zep for chat history. Use Exogram when you need facts, not conversations.
Why I Built Exogram: AI Agents Need Deterministic Governance
An LLM should generate thoughts, but it should never possess unilateral execution authority. Separating reasoning from physical tool permissions is the only way to deploy agents safely.
What Zep Does
- •Zep provides long-term ledger through conversation history management and automatic summarization.
- •Enriched context retrieval from past conversations.
- •Stores conversation threads — not governed facts. No encryption. No conflict detection.
What Exogram Does
- Exogram stores governed facts — not conversation threads.
- Every entry is verified, encrypted, conflict-checked, and attributed with full provenance.
- Facts are different from conversations. Conversations are raw. Facts are verified.

Frequently Asked Questions
What's the difference between storing conversations and storing facts?
Conversations are raw dialogue. Facts are extracted, verified, conflict-checked, and attributed claims. A conversation might contain "the sky is blue" and "the sky is green" — Exogram would detect the contradiction. Zep would store both.
