Simple plans. Same optimizer.
Use PromptShield free each day, or remove the daily limit with Pro.
Free and Pro use the same optimizer. Context Brain is optional on both. With your permission, Quick Check in ChatGPT can use up to six recent messages from the current conversation so a follow-up stays specific. It stays off until you turn it on, and it does not read your other chats.
