FAQ

Common questions

Are these tools really free?

Yes. All 18 tools above are free to use, with no account required. They run directly in your browser or against our lightweight public endpoints — no hidden credit meters, no paywalls.

Do you store my uploaded documents?

No. Files uploaded to the counting and analysis tools are processed in memory and discarded immediately after you get a result. Nothing is written to long-term storage, and nothing is shared with third parties.

What's the difference between free and paid?

The free tools are single-purpose utilities — count words, detect a language, compare text. The paid Vernacia product translates entire business documents end-to-end while preserving formatting, layout, fonts, charts, and images across 14 formats.

Can I use these tools in my business?

Yes, the tools are free for personal and commercial use. If you need programmatic access for a production workflow, consider an Enterprise plan — it includes a documented REST API and webhooks.

Do I need to register?

No registration, no email, no credit card. Open the tool, paste your text or drop your file, and get an answer.
