Communication intelligence

How will this message land?

ProTone reads the room before you send. Get risk flags, perception forecasts, and audience-aware rewrites — right inside Gmail, Slack, LinkedIn, and every text field.

Free plan: 20 analyses/month. No credit card required.

Not grammar. Communication outcomes.

Wordtune fixes your sentences. ProTone tells you whether the message will achieve what you need — with the person you're talking to.

Risk analysis

Spot accusatory tone, passive aggression, unclear intent, and escalation before damage is done.

Perception forecast

Predict how your audience will react — trust impact, cooperation likelihood, and likely emotional response.

Audience-aware rewrites

Get recommended, friendly, and direct versions tailored to your audience and goal — then paste with one click.

Works where you write

A floating button appears in any text field — just like Grammarly, but for how your message lands.

1

Focus a text field

The ProTone button appears in Gmail, Slack, LinkedIn, or any editable field on the page.

2

Choose audience & goal

Tell ProTone who you're writing to and what you want to achieve — manager, client, follow-up, feedback, and more.

3

Send with confidence

Review risk, perception, and rewrites. Use a rewrite directly in the field, or copy and send your way.

Questions

Do you store my messages?

No. Messages are analyzed in real time and never stored on our servers. We don't build a history of what you write.

How is this different from Grammarly or Wordtune?

Those tools improve how you write. ProTone analyzes how your message will be received — based on audience, goal, and communication risk.
