Yes. We use OpenAI's GPT-4o model directly through their official API. It's the same model, same capabilities — we just wrap it with persistent memory and a better conversational experience.
We'll be transparent about it. If GPT-4o is no longer available through the API, we'll notify you in advance and help you export all your data and memories. No surprises, no lock-in.
You can import your ChatGPT memory and instructions. We use these to give 4o the context it needs to continue naturally from where you left off — no re-explaining needed.
Your conversations are encrypted and never used for training. You can export or permanently delete all your data at any time. We don't sell or share your information.
ChatGPT Plus no longer offers GPT-4o as of February 2026. We provide dedicated access to the model with enhanced memory that persists across all your conversations — something ChatGPT never fully delivered.
Your conversations deserve to continue.
