PromptEditor

PromptEditor is a Chrome extension that helps you work more efficiently with AI chatbots. It adds an 'Edit in PromptEditor' button below responses on Claude, ChatGPT, Gemini, Perplexity, and Copilot. When clicked, it opens a side panel with the AI's response loaded and ready for editing. You can fill in placeholder text, apply formatting like bold and bullet points, and then send the refined prompt directly back to any supported AI chat or copy it as clean Markdown.

The tool stands out through its seamless integration and focus on practical editing features. It automatically detects placeholders in brackets or curly braces, letting you click to fill them with actual values. A rich text editor allows visual formatting while maintaining proper Markdown structure. Global variables can be set once to auto-fill repeated terms across different prompts. Everything operates locally in your browser with no accounts, servers, or data collection—your prompts never leave your machine.

This extension is most valuable for people who frequently use multiple AI systems and want to maintain consistency across them. Researchers can use it to refine literature review requests, content creators can develop reusable template prompts for different projects, and anyone working with AI regularly will appreciate the reduced tab switching and streamlined workflow. It turns the often messy process of copying and reformatting AI responses into a simple three-step operation.
