Questions

Is my image uploaded?

No. Text recognition runs in this tab with Tesseract compiled to WebAssembly. The only downloads are the engine and the language data (from the jsDelivr CDN, cached after the first time); your image is never part of any request.

Does it work for Telugu, Kannada or Malayalam?

Yes. Each has its own model in the language list: Telugu, Kannada and Malayalam. Choose the one that matches the script in the image.

What affects accuracy most?

Image sharpness and size. Tamil vowel signs are small, so photograph close enough that a line of text is at least 30 pixels tall, and keep Clean up on for paper.
