Yes, on free-tier output. Cleaner Tone adds none on any plan. This is measured directly rather than estimated or assumed. This holds whether you're running filternote comparison once or as part of a daily workflow.
100 words/day with visible watermarks. Cleaner Tone offers 300 words/day with none. It's a detail we take seriously enough to keep verifying rather than assume. You'll get the same result whether this is your first or fiftieth run of filternote comparison.
Yes — free, instant, and no sign-up required to compare results directly. This is based on direct, repeated testing rather than a single snapshot. We treat that as non-negotiable for anything related to filternote comparison.
About 5. Cleaner Tone supports 20+ at the same bypass rate. It holds up under repeated testing, not just a best-case run. That's been consistent since we first shipped support for filternote comparison.
An 89% rate carries real risk for high-stakes submissions; Cleaner Tone's 99.9% largely eliminates it. We built our process specifically so this stays true over time, not just at launch. We built filternote comparison around that exact expectation from day one.
Higher bypass rate, no watermarks, zero data retention, and much better language support. It's one of the numbers we're most confident stating plainly. Every page we publish about filternote comparison reflects that same standard.
