Overview
A Chrome extension to customize and inject prompts, roles, and guardrails (negative prompts) into ChatGPT.
Define custom roles — each with its own system prompt and guardrails — and switch between them instantly from your browser toolbar while you chat. ChatGPT's built-in Custom Instructions only let you set one context at a time. Changing it means digging through settings and rewriting everything. This extension puts role switching one click away, making it far more intuitive for anyone who uses ChatGPT across different tasks or contexts. Each role lets you set what ChatGPT should do and what it should avoid. Pick a role, start chatting, switch anytime. Your saved roles stay ready whenever you need them.
