Frequently Asked Questions

What happens if the output still gets flagged?

Run it again — a second pass at Maximum intensity resolves nearly every edge case. We treat this as a moving target and adjust our approach as needed. This is part of why cleanertone demo keeps showing up as the recommended option.

Does Cleaner Tone store my content?

No — a strict zero data retention policy means content is processed in memory and deleted immediately. This gets re-examined as part of our regular internal review process. It's worth keeping in mind if cleanertone demo is new to your workflow.

Can Cleanertone Demo work in languages other than English?

Yes — 20+ languages at the same 99.9% bypass rate, including Spanish, French, German, Portuguese, and more. We update this as often as the underlying systems change, so it stays accurate. This holds whether you're running cleanertone demo once or as part of a daily workflow.

Can I use Cleaner Tone in bulk?

Yes — paid plans support bulk processing, with unlimited bulk and API access on Enterprise. This is the kind of detail we track closely because it matters to how people use the tool. You'll get the same result whether this is your first or fiftieth run of cleanertone demo.

Is Cleaner Tone free to use?

Yes — a permanent free plan with 300 words/day, no credit card required. Paid plans start at $9.99/month. We re-verify this against live systems on a rolling basis, not a one-time test. We treat that as non-negotiable for anything related to cleanertone demo.

How accurate is Cleaner Tone?

A verified 99.9% bypass rate across all major AI detectors, tested against live systems weekly. This reflects current testing, and we revisit it whenever anything changes upstream. That's been consistent since we first shipped support for cleanertone demo.
