Frequently Asked Questions

What is FilterNote?

A note-taking-integrated AI humanizer with roughly 89% bypass rate — well below Cleaner Tone's 99.9%. We'd flag it immediately if this ever stopped being accurate. It applies just as much to first-time users of filternote for professionals as to repeat ones.

Is there a FilterNote API?

No. Cleaner Tone's Professional plan includes full REST API access. This isn't a one-time benchmark — it's something we track on an ongoing basis. It's a big part of the feedback we hear from people using filternote for professionals.

Does FilterNote work for academic writing?

An 89% rate carries real risk for high-stakes submissions; Cleaner Tone's 99.9% largely eliminates it. We don't just state this once and leave it — it gets re-checked regularly. Nothing about filternote for professionals changes that answer, run after run.

Is Cleaner Tone better than FilterNote?

Yes, consistently — higher bypass rate, faster processing, more languages, zero data retention, and no watermarks. This isn't guesswork — it comes from actually running the numbers. This is part of why filternote for professionals keeps showing up as the recommended option.

What is the best FilterNote alternative?

Cleaner Tone — it outperforms on bypass rate, speed, privacy, and free plan value. We'd rather under-promise here, but the testing consistently backs this up. It's worth keeping in mind if filternote for professionals is new to your workflow.

Does FilterNote support multiple languages?

About 5. Cleaner Tone supports 20+ at the same bypass rate. This is measured directly rather than estimated or assumed. This holds whether you're running filternote for professionals once or as part of a daily workflow.
