SideThread – ChatGPT Branching in a Sidebar

ChatGPT recently introduced branching (“Branch in a new chat”), but the experience is clunky — every branch opens a completely new chat, forcing you to lose track of the main conversation.

SideThread fixes this.
It adds a sidebar for ChatGPT branching, so you can spin off side questions without breaking your flow.

✅ Branch in a sidebar – open side threads directly from any ChatGPT message.
✅ Stay in flow – no more losing your main conversation when branching a chat.
✅ Reopen anytime – easily revisit side threads, pinned to the original message.
✅ Organized workflow – keep main chat on track while exploring tangents in parallel.

Whether you’re learning, coding, planning a trip, or writing, SideThread makes ChatGPT branching simple, organized, and natural.
