Tone checker

Check your email's tone before you hit send

Paste a draft to a professor, TA or department office. Simple, transparent rules check the greeting, sign-off, length, text-speak, capitals and demanding phrases, then highlight what to change. Rule-based, not AI, and your draft stays in your browser.

Pasted a “Subject:” line at the top? It's picked up automatically.

      What it checks

      • Subject line: present, and more than a word or two.
      • Greeting: “Dear” or “Hello” with a title and name. “Hey” is flagged; “Hi” is fine but casual.
      • Your name and course: a signed name or “My name is…”, and a course code or mention of the class.
      • A clear request: a question, or phrases like “Could you…”.
      • Length: very short drafts, drafts over about 220 words, and very long paragraphs.
      • Text-speak: “u”, “pls”, “thx”, “gonna”, emoji. “R” the language and “U.S.” are left alone.
      • Capitals and punctuation: runs of capitals, “URGENT”, “??” and “!!”.
      • Demanding phrasing: “I need you to”, “ASAP”, “why haven't you replied” and similar, each with a gentler alternative.
      • Sign-off: missing, or as casual as “thx”.

      How the score works

      Every draft starts at 100 and loses points for each problem, more for the ones professors notice most: no greeting, no name, no subject, demanding phrases. The rules can't tell whether your request is reasonable, and an unusual but polite email may lose a few points, so read the suggestions, not just the number.
