ProTone

About

How will this message land?

ProTone is communication intelligence for professionals. Before you hit send, it analyzes how your message might be received — not just whether the grammar is correct.

Unlike grammar tools, ProTone focuses on outcomes: Will this sound accusatory? Will your manager get defensive? Will a client trust you less? ProTone tells you before the damage is done.

WHAT YOU GET

• Risk analysis — spot accusatory tone, passive aggression, unclear intent, and escalation risks
• Perception forecast — likely reaction, trust impact, and cooperation likelihood
• Audience-aware rewrites — recommended, friendly, and direct versions tailored to who you're writing to and what you want to achieve
• One-click paste — apply a rewrite directly in the field

WORKS WHERE YOU WRITE

ProTone appears as a floating button in text fields across the web — Gmail, Slack, LinkedIn, Notion, support tickets, and any editable field. No tab switching. No copy-paste into another app.

HOW IT WORKS

1. Focus a text field — the ProTone button appears
2. Choose your audience and goal (manager, client, follow-up, feedback, and more)
3. Review risk, perception, and rewrites — then send with confidence
