How does Grammarly's tone detector work?

If you use the Grammarly browser extension, you may have seen a small emoji next to the Grammarly logo. This is Grammarly's tone detector, a feature that can help you:

  • Detect the emotions you are potentially trying to convey to your reader in your writing. This is called emotional tone, and you can learn more about it here.
  • Detect how formal or informal your writing may seem to your reader. This is called formality, and you can learn more about it here.
  • Detect other types of tones in your text.
  • Give Grammarly feedback on whether the tones detected match your expectations.

As one of Grammarly's features, Grammarly’s tone detector still adheres to the privacy practices outlined in the Privacy & Security section here, and it falls under the same Privacy Policy.
