TokenLens - See every token. Fix every prompt. Learn why it works.

Paste any AI prompt and instantly see where your tokens are going, what it costs, and how to fix it. TokenLens gives you a full token breakdown, cost estimate, optimized rewrite, and a prompt score card — plus the principle behind every change so you actually get better at prompting. Free to start. No credit card.

Hey PH! 👋 Maker here. I built TokenLens after noticing how much of my Claude API spend was pure waste — politeness phrases, redundant context, vague instructions. Most prompts are 30-70% bloat and you can’t see it until you break it down. What makes TokenLens different from other prompt tools: it doesn’t just hand you a shorter prompt. It tells you why each change was made and what principle to apply next time. After a week of using it you stop needing it for simple prompts — because you’ve internalized the patterns. A few things I’d love feedback on: — Does the score card (clarity / conciseness / structure / specificity) feel useful or gimmicky? — Is Challenge Mode something you’d actually use to practice? — What type of prompts would you most want to analyze? Free plan is genuinely useful — 3 analyses per day, no credit card. Jump in and let me know what you think 🙏
