Tone of voice checker

The tone of voice checker that keeps every draft in key

Claritar's tone of voice checker scores how well any draft matches your client's tone, from formal to playful, flags where it drifts, and rewrites it to land right.

Tone dials

Set the tone once, check it on every draft

Define where each client sits, formal or casual, serious or playful, and Claritar scores every draft against those dials, so the tone is never a matter of opinion.

  • Per-client tone dials across four axes
  • A clear read on how on-tone each draft is
  • The exact lines where the tone slips
  • A rewrite that brings it back into key

Questions

Tone of voice checker FAQ

What is a tone of voice checker?+

It's a tool that measures how well writing matches a defined tone. Claritar scores each draft against per-client tone dials, flags where the tone drifts, and rewrites it to match.

How do the tone dials work?+

You place each client on spectrums like formal-to-casual and serious-to-playful, and set a target reading level. Claritar scores every draft against those settings.

Can it check readability too?+

Yes. A target reading level feeds into the score and the rewrite, so the tone of voice analysis covers how easy the writing is to read, not just its register.

Is the tone checker free to try?+

Yes. Start free and check drafts against one client's tone, no credit card required. Paid plans add more clients, seats and features.

Will the same draft get the same tone score?+

That's the goal. Claritar is built to score consistently, so re-checking an unchanged draft returns the same result.
