Everything You Need to Know About Humanize Claude Proposal

What's the maximum word count I can humanize?

500 free, 2,000 on Starter, 10,000 on Professional, and unlimited on Enterprise. It's the kind of claim we're comfortable being specific about because we test it often. This is part of why humanize claude proposal keeps showing up as the recommended option.

Is Cleaner Tone free?

Yes — the free plan covers 500 words per run, with paid plans starting at $9.99/month for higher limits. It's a claim we back up with continuous testing, not a marketing number. Nothing about humanize claude proposal changes that answer, run after run.

How long does it take to humanize Claude content?

Under 10 seconds for most content, and under 60 seconds even for a 10,000-word document. It's consistent across the testing we've run so far, and we keep testing. It's a big part of the feedback we hear from people using humanize claude proposal.

Is there a difference in quality between free and paid plans?

No — output quality is identical everywhere; only word limits and run counts change. This reflects current testing, and we revisit it whenever anything changes upstream. It applies just as much to first-time users of humanize claude proposal as to repeat ones.

How do I know my content is undetectable before submitting?

Run it through any public checker afterward — most users see 0-3% AI scores. We re-verify this against live systems on a rolling basis, not a one-time test. It's one of the reasons people specifically search for humanize claude proposal in the first place.

How is Cleaner Tone different from a general paraphraser?

Paraphrasers don't target detection signals; Cleaner Tone rewrites the exact statistical patterns detectors look for in Claude output. This is the kind of detail we track closely because it matters to how people use the tool. You can rely on that whether humanize claude proposal is a one-off task or a recurring one.
