Most brands don't lose their voice writing; they lose it translating. The blog post sounds like them, then the LinkedIn version comes out stiff, the tweet comes out desperate, and the email sounds like a different company entirely.
The fix: your voice never changes across channels. Your settings do. Length, structure, and formality flex; personality holds. This guide gives you the prompt pattern and the per-channel settings to make that reliable, and it's the practical companion to the Experience pillar. For platform-specific social settings, see the Social Media Voice Pack.
The channel-switch prompt pattern
Every recast uses the same skeleton:
You write for a brand with this voice: [PASTE VOICE CHARTER]. Recast the piece below for [CHANNEL]. Keep: the core idea, the voice, and every fact and number exactly as written. Change: length to [TARGET], structure to [STRUCTURE], and formality [SHIFT]. Do not add new claims or examples. Do not open with a hook formula. End with [CTA STYLE]. Piece: [PASTE ORIGINAL]
The "Keep / Change / Do not" structure is the whole trick. Without an explicit Keep line, AI treats a recast as a rewrite and your voice goes with it.
Per-channel settings table
Plug these values into the pattern. Adjust once for your brand, then reuse forever.
| Channel | Length | Tone shift | Structure | CTA style |
|---|---|---|---|---|
| Blog | 600 to 1,200 words | Baseline voice, most room to breathe | Clear headline, short intro, subheads, one idea per section | Soft: related resource or next read |
| 100 to 200 words | Slightly more personal, first-person moments | Strong first line, short paragraphs, white space, single idea | A question or plain ask | |
| X | Under 250 characters | Sharpest version of you, zero padding | One sentence or two, the observation stands alone | Usually none; the post is the point |
| 150 to 300 words | Warmest, like writing to one person | Greeting, one story or point, one link, sign-off | Direct: one link, one ask, stated plainly | |
| Support | As short as the fix allows | Calm and warm, personality dialed down (not off) | Acknowledge, numbered fix, invitation to reply | "Reply if this doesn't sort it" |
Two notes on the table. First, "tone shift" is a nudge, not a costume change: a 7/10 casual brand becomes an 8 on X and a 6 in support, never a 2. Second, support gets the least personality because a frustrated reader wants competence first; your voice shows in the warmth and the total absence of corporate filler, not in jokes.
Worked example: one paragraph, three channels
Original (from a blog post by a bookkeeping service for freelancers):
Most freelancers don't have a money problem, they have a visibility problem. They're earning fine, but every number lives in a different place: invoices in one app, expenses on a card statement, taxes in a folder of dread. So every financial decision gets made on vibes. The fix isn't more discipline. One weekly 20-minute review, with everything in one view, beats any budgeting resolution you'll abandon by March.
Recast for LinkedIn (settings: 100 to 200 words, more personal, strong first line, question CTA):
A client told me she "wasn't a numbers person." She was earning six figures freelance.
She didn't have a money problem. She had a visibility problem. Invoices in one app, expenses on a card statement, taxes in a folder she was scared to open. Every decision made on vibes.
We set up one 20-minute weekly review, everything in one view. No budgeting app, no resolutions. Three months later she raised her rates, because for the first time she could see she was undercharging.
Freelancers: where do your numbers actually live?
Recast for X (settings: under 250 characters, sharpest version, stands alone):
Most freelancers don't have a money problem. They have a visibility problem. Invoices here, expenses there, taxes in a folder of dread. You can't decide on numbers you can't see.
Recast for email (settings: 150 to 300 words, warmest, one ask):
Hey [name],
Quick question before anything else: if I asked what you earned last month, could you answer without opening three apps?
Most freelancers I work with can't, and it has nothing to do with discipline. Their numbers are just scattered. Invoices in one tool, expenses on a card statement, tax stuff in a folder they avoid. So decisions about rates, spending, and saving all run on gut feel.
The fix is smaller than you'd think: a 20-minute weekly review with everything in one view. I wrote up exactly how to set one up, including the template I use with clients.

Talk soon, [name]
Notice what stayed identical across all three: the core idea (visibility, not discipline), the key phrase ("folder of dread" survived twice because it's the most on-voice line), and the personality. What changed: length, structure, intimacy, and the ask.
Your turn: the 20-minute run
- Pick one finished piece you like (5 min to choose and trim to its best paragraph).
- Fill the prompt pattern with your Voice Charter and the LinkedIn row. Generate (3 min).
- Repeat for X and email (6 min).
- Read all three aloud back to back. They should sound like one person in three rooms. If one sounds like a stranger, tighten the Keep line and regenerate (6 min).
Save your filled-in settings table. Next recast takes five minutes, and your voice arrives everywhere intact.
