Free tools
Small, free utilities that solve one specific problem - no account needed.
Free OCR for printed text (private, in-browser)
Extract text from a printed image - nothing is uploaded, the recognition runs entirely on your own device. Not for handwriting - see Scriveno's main converter for that.
Free LaTeX checker
Paste LaTeX, click check, and see whether it compiles - with the exact error when it doesn't.
Free LaTeX to Word converter
Paste LaTeX and download an editable Word (.docx) file.
