Do You Tend to Write Overly Verbose AI Prompts?

Every line of text you send to ChatGPT, Claude, or any API is billed in tokens — repeated system instructions, long background explanations, and overly detailed context often make up the bulk of it.

In other words: You’re being chatty, and tokens are burning 🔥

PromptLean

PromptLean is a newly launched lightweight web tool, currently still in PoC (proof of concept) stage.

Its original purpose is to promote pr402/x402 payments, but at this stage its bigger value is simpler:

It helps you shorten AI prompts without changing their meaning — and shows you exactly how many tokens you saved.

Each user gets 10 free optimizations per day.

It compresses your long, rambling prompts and reduces token usage.

After a few uses, you can decide whether it fits your workflow and needs.

How to Use

• Paste your verbose prompt (any language supported)
• Choose a mode — “Balanced” is recommended as the default
• Click “Optimize”
• Copy the optimized result and paste it into your usual AI tool

Language stays the same: English input → English output, Chinese input → Chinese output.

Key Notes

• No registration required
• Free quota: 10 optimizations per day
• No wallet connection needed within free tier

Pricing

• Daily subscription: 0.75 USDC
• Quota: 200 optimizations within 24 hours
• Average cost: ~0.004 USDC per request (much cheaper than pay-per-use at 0.03 USDC each)

If you optimize prompts daily, the daily subscription is the most cost-effective option.

You can connect a Solana wallet (such as Backpack or Phantom) and subscribe once to use it for the day. The subscription credential is stored locally in your browser and can be used until it expires.

Hourly and monthly plans are also available for different needs.

Who Is It For?

• People who repeatedly paste the same “system prompts” every day
• Developers building AI products or writing many prompts
• Individuals or teams with high API usage who want to reduce cost without switching models

Core Value

It makes your prompts shorter while preserving meaning — reducing cost for every AI call.

Final note: PromptLean is still in a fast-moving PoC stage. Errors and changes are expected, and feedback is welcome.

If you find yourself being too verbose, try pasting your prompt and see how much you can save first.
