ChatGPT Split & Merge Chats

Split long chats, move parts to new/existing chats, and auto-carry context

Auto Split & Merge for ChatGPT is a lightweight helper that keeps long conversations tidy and fast. When a chat drifts across topics—or simply gets heavy—hit Split to move a slice of the thread into a fresh chat or into an existing one. Your new message opens pre-filled with a link back to the source, a compact pre-context (last N turns), and an auto-summary of the selected range. 🔗 Main Features: ✂️Split from any message or select a range (start → end) to extract exactly what matters. 📁Send to a new chat or an existing chat (paste a URL or pick from a scraped list of recent chats). 🔗Fully customizable handoff template (title, language, placeholders: link, indices, pre-context, summary). ⚡️Auto-send option: the handoff is inserted and submitted for you—perfect for workflow “handoffs.” 📌Optional auto-split after a threshold (e.g., 50 messages) with an on-page badge counter and confirmation. 🔗Works across regular chats and ChatGPT Projects (/g/), with robust insertion into the ProseMirror composer. 🧩Designed to be resilient against laggy UIs: multiple insertion strategies, caret placement, and retries. Why it’s useful: a) Keep knowledge organized by topic instead of burying gems in a monolithic thread. b) Reduce friction when performance dips: roll over to a new chat without losing context. c) Make past work discoverable and reusable with consistent, link-rich handoffs. d) Everything runs locally in your browser; no external services required.
