About GhostGPT - Recover Old ChatGPT Chats
Old ChatGPT conversations can sometimes become impossible to open when they grow too large and trigger a 413 content-too-large error. GhostGPT helps you bring those chats back using your official ChatGPT export.
Import your exported conversation data, choose the old chat you want to recover, and GhostGPT guides you through a safe branch-based restore flow so the conversation can become accessible again in ChatGPT.
GhostGPT runs locally in your browser, stores imported data in local extension storage, and is built for one focused purpose: rescuing valuable old ChatGPT chats that would otherwise stay stuck behind a loading or content-too-large failure.
