About ChatExtender

ChatExtender is a Mac application that integrates with your existing ChatGPT and Claude accounts to enhance their functionality. It provides persistent memory so conversations retain context even as they grow long, eliminating the loss of critical details that often occurs in standard chat interfaces. The app automatically maintains a running summary of each session and preserves saved notes and files, ensuring continuity across interactions. All conversation history is stored locally on your Mac, keeping data private and secure without cloud dependency. Users can perform full-text searches across every chat, making it easy to locate specific information from past exchanges. The tool is designed for individuals who rely on ChatGPT or Claude for extended or recurring tasks and need reliable context retention. It operates as a wrapper around your logged-in accounts, requiring no additional setup beyond installation and a one-time purchase. The app is currently available as a private beta with a one-time fee of $30 and no subscription required.
