About these notes

OpenAI Notes explains the products people look up around OpenAI: what Crixet became, what ChatGPT Plus costs, where Codex usage lives, and which login matches which bill.

We are not OpenAI. We do not sell Plus, we do not hold API keys, and we never ask for a password. Sign in only on chatgpt.com or platform.openai.com.

Prices and cutoffs on these pages were checked against OpenAI’s help center and product posts on 27 September 2026. When a figure is a promo window or a paused plan, the sentence says so. The checkout page is still the price you pay.

The blossom in the header is OpenAI’s favicon, used so the tab matches the product. Usage rules for the mark are on openai.com/brand.
