Claim
Using ChatGPT's 'Branch in new chat' with a stable taxonomy and one-purpose-per-branch lets product marketers create clear, reusable workstreams that scale strategy into assets without wrecking the main thread.
Mechanism
The branching preserves full context (prompts, uploads, images, Deep Research results) so you can spin off focused workstreams. A stable prefix taxonomy (STR, MSG, PER, etc.) makes search and custom GPT references easy. One purpose per branch prevents confusion, and archiving dead ends keeps the workspace clean.
