The Problem

OpenAI's Custom GPTs have no persistent memory API. Each conversation starts blank. Your custom GPT can't remember what users told it yesterday, can't build on previous interactions, and can't prove what it knew when it responded.

Memory that persists across ChatGPT conversations.

• • • Conversation 1
User: I prefer window seats on flights
✓ Stored · rct_bb12 · 0.99
• • • Conversation 2 (next week)
User: Book me a flight to NYC
✦ 4 preferences loaded
Searching for window seat options...
Preference: rct_bb12 · still valid

Your GPT remembers. With proof.

Ingest + Extract
Step 3
Verify + Receipt

The Fix

No npm install — configure in GPT Builder using OpenAPI action.

Coming soon — package not yet available. Code below shows the planned API.

# Coming soon — package not yet available // In ChatGPT GPT Builder → Actions → Add Action // Import OpenAPI spec from: // https://api.verifiedstate.ai/openapi.yaml { "openapi": "3.1.0", "info": { "title": "VerifiedState Memory", "version": "1.0.0" }, "servers": [{ "url": "https://api.verifiedstate.ai" }], "paths": { "/ingest": { "post": { "summary": "Store a verified fact" } }, "/query": { "post": { "summary": "Query verified memory" } }, "/verify": { "post": { "summary": "Verify an assertion" } } } } // Your Custom GPT now has persistent verified memory

FAQ

How do I set this up?

In GPT Builder, go to Actions → Add Action. Import the OpenAPI spec from api.verifiedstate.ai. Add your API key as a Bearer token. Full setup guide in the docs.

Does it work with the free tier?

Yes. The free tier is generous enough for most Custom GPTs. Pro is $19/mo for higher limits.
