AI code fixer

Paste broken code. See the bug free. Unlock the fix.

Paste the code that fails, and the error if you have it. CoreMesh AI finds the bug and tells you what's wrong for free. If you want the fixed code, unlock it with a small USDC or ETH payment on Base.

You only pay if a fix is found. 5 free checks a day. Your code is used only for this check and deleted within 48 hours.

2See what's wrong

Your result shows up here. Paste some code and press Check my code. A check usually takes 3–10 seconds.

How it works

  1. Paste and check, free. The AI reads your code and the error, then tells you the line and the reason it fails.
  2. Unlock the fix. Pay $0.50–$2 depending on length, in USDC or ETH on Base. The ETH amount follows the live ETH/USD price.
  3. Copy and run. You get a red/green diff and the complete fixed file. If it still fails, re-check once for free within 24 hours.

Questions

Is the check really free?

Yes. You get up to 5 checks a day. Each one shows the line with the bug and why it fails. You only pay if you want the fixed code.

How much does a fix cost?

$0.50 for up to 40 lines, $1 for 41–150 lines and $2 for 151–300 lines. If you pay in ETH, the amount follows the live ETH/USD price when you open the payment.

How do I pay?

With USDC or ETH on the Base network, from any wallet (Coinbase Wallet, MetaMask, Rainbow and others). Send the exact amount shown. The fix unlocks by itself a few seconds after the payment lands.

Is my code stored or shared?

Your code is sent to the AI model only to check it, kept on the server only to show your result, and deleted within 48 hours. It is never published or used to train anything here.

Which AI does it use?

CoreMesh AI runs strong open models (Qwen, DeepSeek and GLM) through DigitalOcean's inference API, with an automatic fallback if one is busy.

What if the fix doesn't work?

Press “Didn't work? Re-check free” within 24 hours and paste the new error. The AI gets one more try at no cost. Blockchain payments can't be reversed, so if anything went wrong with a payment, email [email protected] with the transaction hash.

I paid but the fix didn't unlock.

Open “Already paid? Paste the transaction hash” under the payment box and paste your transaction hash. If the amount was different from the one shown, email us with the hash and we'll sort it out.

The fixer is a tool, not a guarantee: always run your tests before you ship a fix. See the terms and privacy policy.
