ChatGPT Chat Merge

About

Merge multiple ChatGPT chats into one new conversation — with their full context intact.

ChatGPT keeps every chat in its own silo. Hit "You've reached the maximum length for this conversation" and hours of work are stranded in a dead thread. Start a new chat and you're back at square one, re-explaining everything to a blank assistant that doesn't know who you are. Chat Merge for ChatGPT combines two or more of your conversations into one brand-new chat, pre-seeded so you can continue exactly where you left off — no copy-paste, no re-explaining, no starting over.

── WHAT IT DOES ──
• Merge two or more ChatGPT chats into a single new conversation.
• Consolidate the full history of every selected chat — losslessly, nothing dropped.
• Continue a maxed-out conversation after it hits its length limit.
• Turn a dozen scattered research chats into one source of truth.
• Onboard a fresh chat with everything it needs in one click.

── HOW IT WORKS ──
Open any chat's ⋯ menu → "Merge Chats." Pick the conversations to combine (and, optionally, type what you want to do next to steer it). Each chat is condensed into a faithful "handoff briefing" — and if anything can't be condensed, that chat falls back to its full transcript, so nothing is ever silently lost. The briefings are joined, an additive "current state / open threads" summary is synthesized across them, and a new chat opens already loaded with all of it. Preview and edit before sending, or auto-send. Copy or download the result as Markdown any time.
