The Problem

Letta (MemGPT) has the most interesting memory architecture — agents manage their own memory. But it's a full agent platform, tightly coupled. There's no independent verification of what agents remember.

Step 1
Connect
Step 2
Ingest + Extract
Step 3
Verify + Receipt

The Fix

npm install @verifiedstate/letta

Beta: tagging-level integration. Ingestion works via @verifiedstate/sdk with Letta-specific source tagging. Native Letta features coming.

// Use VerifiedState as external verification layer // Letta agents manage memory → VS verifies it

FAQ

Does it replace Letta's memory?

No. It adds an independent verification layer. Letta manages memory, VS verifies it.
