Which tool should we build next?

MyToolsKart now has 75+ free tools across PDF, image, developer, AI and calculators — all running privately in your browser (nothing gets uploaded).

I'm deciding what to build next. A few I'm considering:
• OCR PDF (extract text from scans)
• Background remover for images
• Password-protect / unlock PDF
• More AI writing tools
