Frequently Asked Questions

Is there a quality difference between free and paid plans?

Does Cleaner Tone store my content?

What happens if the output still gets flagged?

Run it again — a second pass at Maximum intensity resolves nearly every edge case. We'd flag it immediately if this ever stopped being accurate. It's worth keeping in mind if cleaner tone for writers is new to your workflow.
