ProTone

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 PRIVACY Messages are analyzed in real time and are not stored on our servers. We do not build a history of what you write.
