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 🙏
