Custom GPTs forget between conversations. VerifiedState gives them a persistent, verified memory backend.
Get API Key →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.
Your GPT remembers. With proof.
