About this extension
You already know the email sounds off. You've rewritten it three times. You're still not sure. You send it anyway and spend the next four hours wondering if "just checking in" was a mistake.
Tact is for that moment.
Highlight any text in your browser and Tact tells you exactly how it reads - Cold, Passive-Aggressive, Warm, Diplomatic, Needy - with a plain-English explanation and phrase-level highlighting showing which specific words are doing the damage.
Pick a mood from the rewrite picker and Tact rewrites the text for you. Copy it in one tap and carry on.
Ten rewrite moods including Diplomatic, Warmer, More Direct, Concise, Firmer, Chill, Hype, Softer, Passive Aggressive - and Angry, which shows you what you actually wanted to write.
Works in Gmail, Outlook, LinkedIn, Slack, and most other websites. Your text is never stored.
