ChatGPT Enhances Chat History Search for Plus and Pro Subscribers

• ChatGPT Plus and Pro subscribers can now reliably search their entire chat history, addressing a long-standing user pain point.
• The new update, internally called PersonalContextAgentTool, allows users to ask questions referencing any past chat, improving information retrieval.
• A key feature is transparency: ChatGPT displays a clickable reference to the original chat when pulling information, allowing users to verify context.
• This update is a significant quality-of-life improvement, especially for long-term users who use ChatGPT as a personal knowledge base.
• While a welcome change, ChatGPT is playing catch-up, as Google's Gemini introduced similar context-aware interactions in February 2025.

Why It Matters: ChatGPT now offers reliable, transparent chat history search for Plus/Pro users, enhancing its utility as a long-term assistant.
