Grammarly for AI prompts — inline suggestions to optimize your prompts on Claude, ChatGPT, and Gemini. PromptLens makes your AI prompts sharper — automatically. Like a spell-checker for prompts, it watches the input box on Claude, ChatGPT, and Gemini and suggests a cleaner, more effective version of what you typed. Accept with one keystroke, or ignore it. Your prompt, your call. WHAT IT DOES - Inline suggestions — a quiet indicator appears as you type. Press Tab to accept the improved prompt, Esc to dismiss. - Removes the noise — strips filler words, redundant pleasantries, and bloat that waste tokens and muddy your intent. - Adds structure — for vague or short prompts, it suggests clearer formatting, constraints, and output specs so the AI gets it right the first time. - Works where you already work — Claude, ChatGPT, and Gemini, with no copy-pasting between tools. YOUR COGNITIVE SHADOW The more you use PromptLens, the better it understands how you work — the domains you focus on, your preferred output formats, your recent topics. It uses this to tailor suggestions to you. You can see everything it has learned, export it, or clear it anytime. It's stored only on your device and never leaves your browser. PRIVACY FIRST - No account required. No name, no email, no sign-up. - Rule-based cleanup runs entirely in your browser. - AI-powered suggestions send only your current prompt for processing, and it's never stored or used for training. - Your personal profile stays local. Always.

The built-in rule-based cleanup always works.
