About Nithish

Hi, I’m Nithish. I’m one of the guys behind 21K Tools. I got tired of online tools that were slow, full of ads, paywalled or sketchy with privacy, so we built simple free ones that actually feel good to use everything runs in your browser, no account needed (maybe someday), no tracking. I write the guides here from stuff I test and use myself. Got suggestions, problems or ideas? Just email us at contact@21k.tools or fill the form at the Help Center. Follow @21ktools on X for updates.
