BeforePrompt

Perfect your prompt before you hit send — BeforePrompt analyses it locally, flags weaknesses, and rewrites it stronger.

BeforePrompt is an AI prompt optimizer, prompt checker, and prompt engineering assistant that works right inside your AI chat — so you write better prompts and get better answers on the first try. Great AI output starts with a great prompt. BeforePrompt scores your draft in real time as you type, flags what is weak or missing — unclear goals, missing context, no output format, sensitive data — and rewrites it into a stronger, clearer prompt before you hit send. No more vague replies, wasted messages, or re-rolling the same question five times. It works inside the AI assistants you already use, including ChatGPT, Claude, Gemini, and Microsoft Copilot, with more added over time. BeforePrompt appears right next to the prompt box on each supported site, so you can analyze, improve, and refine without copy-pasting into a separate app. What BeforePrompt does: - Real-time prompt scoring and quality checks as you type - Prompt improver that rewrites any draft into a clear, structured, high-quality prompt - Guided Refine — step-by-step prompt engineering to sharpen the goal, context, and output format - Sensitive-data and team-policy warnings before anything leaves your browser - Clear labeling of every suggestion (cloud AI, rule-based, or offline fallback) - Optional, off-by-default prompt history with per-item and clear-all deletion - Pause, global disable, and per-site disable controls — you stay in charge - A curated library of 1,000+ expert prompts across 26 work domains, ready to use from your BeforePrompt dashboard Ready-to-use prompt library: Skip the blank page. Start from a curated library of 1,000+ professionally written prompts across 26 work domains — marketing, sales, engineering, HR, product, support, and more. Every prompt comes with a clear role, the inputs to fill in, and a defined output format, so you go from idea to a high-quality result in seconds. Sign in to your BeforePrompt dashboard to browse and use the full library. Who it is for: Anyone who writes prompts — developers, marketers, writers, founders, students, researchers, and support teams who want consistent, high-quality AI results. Whether you are doing serious prompt engineering or just want ChatGPT and Claude to understand you the first time, BeforePrompt helps you say it better. Why better prompts matter: Most weak AI answers come from weak prompts, not weak models. A clear role, a specific goal, the right context, and a defined output format dramatically improve what any AI assistant gives back. BeforePrompt bakes those best practices into every rewrite, so you spend less time re-prompting and more time getting real work done. Privacy first: Local scoring runs entirely in your browser. Your draft is sent to BeforePrompt and its AI processing provider only when you deliberately choose a cloud action such as Improve or Refine. Conversation context is sent only after you select or approve it. Prompt history is off by default. See the privacy policy for complete details. BeforePrompt never submits a prompt to the AI site for you — you always stay in control of the Send button. Install BeforePrompt and start writing prompts that actually work, before you send.
