I got frustrated constantly copy-pasting broken code into AI and getting inconsistent results. So I built PasteCheck.
You paste JavaScript, Python or HTML and every error gets highlighted instantly. Tap any highlight to see what the issue is. No sign up, completely free, works well on mobile.
Would love feedback from developers:
