Frequently Asked Questions

How long does processing take?

Under 10 seconds for most content, and under 30 seconds even for a full 5,000-word essay. It's consistent across the testing we've run so far, and we keep testing. This holds whether you're running ai humanizer accuracy rates free once or as part of a daily workflow.

What happens if the output still gets flagged?

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. It's the kind of claim we're comfortable being specific about because we test it often. We treat that as non-negotiable for anything related to ai humanizer accuracy rates free.

Can I use Cleaner Tone in bulk?

Yes — paid plans support bulk processing, with unlimited bulk and API access on Enterprise. We'd flag it immediately if this ever stopped being accurate. That's been consistent since we first shipped support for ai humanizer accuracy rates free.

Does Cleaner Tone store my content?

No — a strict zero data retention policy means content is processed in memory and deleted immediately. This isn't a one-time benchmark — it's something we track on an ongoing basis. We built ai humanizer accuracy rates free around that exact expectation from day one.

How is Cleaner Tone different from other AI humanizers?

It targets the exact statistical signals detectors measure, rather than doing surface-level word swaps. We don't just state this once and leave it — it gets re-checked regularly. Every page we publish about ai humanizer accuracy rates free reflects that same standard.
