ChatExtender

Product details from official sources

ChatExtender is a Mac app that gives ChatGPT and Claude persistent memory, long conversations that never lose context, and full-text search across every chat, positioned as memory that carries across ChatGPT and Claude. The headline checklist states a 7-day free trial, 30 dollars once, and local SQLite storage, and the description adds that it is Apple-notarized, local, and private. The product promise is to continue long-running work across fresh ChatGPT and Claude chats, search every synced conversation, and keep chosen project memory privately on the Mac, with one workspace holding every thread from both models so users can switch models and keep going without losing their place. It hands each new session a complete summary of everything before it before anything is lost, and saved items such as writing style and project briefs ride along with every message, so there is zero re-explaining. Because the core offering is a one-time 30 dollar purchase with a free trial, the model is recorded as paid.
