PromptLab Extension

Improve prompts for better AI answers in ChatGPT, Gemini, and Claude.

PromptLab is a Chrome extension that helps you turn prompts written in ChatGPT, Gemini, and Claude into clearer and more useful prompts. When you are writing a question and wondering “Will this get the answer I want?”, open PromptLab to review your current prompt, edit it if needed, and generate an improved version. You can insert the improved prompt back into the AI input box with one click. ✨ Key Features - Detects the current prompt in ChatGPT, Gemini, and Claude - Lets you edit the original prompt inside the PromptLab panel - Improves prompts into clearer and more actionable requests - Shows before/after quality signals - Inserts the improved prompt directly into the AI input box - Lets you rate the answer after using a prompt 🧠 How PromptLab Improves Prompts PromptLab is not designed to simply make prompts longer. It preserves your original intent while checking whether the prompt has enough: - Goal - Context - Output format - Constraints - Reference information or examples For example, a question like “Is there a way to make GPT directly control Microsoft Word?” can be improved into a prompt that asks for possible automation methods, tradeoffs, and implementation examples. A vague prompt like “Write a blog post” can be improved into a prompt that asks for the topic, target audience, tone, length, and key points before drafting. 🚀 Useful For - Users who want more accurate AI answers - People who are not sure how to write effective prompts - Heavy users of ChatGPT, Gemini, or Claude - Writing, coding, studying, summarizing, and analysis workflows 🔒 Data Handling PromptLab sends the prompt you enter to a backend server to provide the prompt improvement feature. The backend server may use the OpenAI API to generate the improved prompt. PromptLab does not store the full original prompt or the full improved prompt in its logs. Stored data is limited to anonymous metadata, such as: - Anonymous user ID - Session ID - Target AI platform - Task category - Before/after analysis metadata - Improvement type and reason metadata - Prompt hashes and character lengths - Satisfaction rating 🌐 Supported Sites - https://chatgpt.com - https://chat.openai.com - https://gemini.google.com - https://claude.ai Use PromptLab to write better prompts and get better answers from AI.
