Frequently asked questions
Is my text sent to a server?
Never. All TextKit tools process text locally in your browser using JavaScript. Nothing is uploaded, logged or stored.
Do the counters match Twitter/X and SEO limits?
Yes — the character counter counts Unicode characters the way platforms do, and shows live limits for tweets, meta titles, meta descriptions and SMS.
Can I use these tools offline?
Yes. Once the page has loaded, every tool keeps working without a connection — nothing depends on a server.
