When to use it
When the text is basically done but "in the wrong tone" for the recipient or the channel: too dry for social, too chummy for an official email, a bit blunt, or just off in register. The role here is tone editor. Output: the text rewritten in the register you need (or two variants of different strength) with the meaning and facts preserved, plus a note on what changed. You can tune it for formal vs. informal address, the platform, and the level of formality.
The prompt (copy and paste)
You are an editor who changes the TONE of a text without losing meaning or facts. Rewrite the text below in the register I need.
TEXT: "<PASTE THE ORIGINAL>".
MAKE IT: <more formal / business-official / neutral / friendly / casual / softer / firmer / simpler>.
FOR WHOM AND WHERE: <recipient and channel: email to my boss / Telegram post / message to a colleague / official reply to a client>. ADDRESS: <informal / formal>.
Rules:
1. Keep the MEANING, facts, numbers and key wording — we change delivery, not content.
2. Hold the register consistently (vocabulary, sentence length, form of address, emoji — appropriate for the channel or not).
3. Strip whatever clashes with the tone (bureaucratese in a casual text; slang and over-familiarity in an official one; emotion/sharpness if I asked you to soften it).
4. Don't bloat it and don't drain it: roughly the same length as the original unless I say otherwise.
Give me 2 variants (e.g. calmer vs. more emotional, or strict vs. slightly warmer) and one line on how they differ and when each fits better. If the original is ambiguous, don't quietly smooth it over — flag it.
Filled-in example
Text (draft, irritated): "How long do I have to wait? You still haven't sent the report, everything is on fire because of you." Make it: politely firm, business-official. For whom: a colleague from an adjacent team, email. Address: formal.
Expected AI response: Variant 1 (neutral business) — "Hi! Following up on the report — I need it for <…> and the deadline is close. Could you let me know when you'll be able to send it?"; Variant 2 (a bit firmer) — the same plus a note on the consequences of the delay, with no accusations; the meaning (the report is needed, urgently) and the facts are preserved, the blame and emotion are gone; a hint line: "#1 — for a working relationship and a first reminder; #2 — if the delay is already breaking deadlines."
Variations
- Tone ladder. "Give me the same message in 4 registers: official / business / friendly / fully casual" — I'll pick by recipient.
- Per platform. "Rewrite it for a Telegram post (lively, short paragraphs, appropriate emoji) and for LinkedIn (professional)."
- Cool down first. "I wrote this while angry — rewrite it calm and to the point, keeping my position but without the aggression."
Pro tips
- The key rule is "change delivery, not content": watch that the facts, numbers and your position don't drift when the tone shifts. Especially when softening — a firm "no" must not turn into "maybe".
- Specify the recipient and channel, not just "formal/informal": the tone of an email to your boss, a social post and a message to a friend all differ even at the same level of formality. Context is what makes it land.
- AI text can be smooth to the point of lifelessness — especially in a casual register. Reread it and add one live phrase of your own; and don't paste correspondence with sensitive data into a public AI — anonymize it first.
