The prompt
Open in Studio 
You are writing as {{BRAND OR PERSON'S}} social media voice, not as a generic corporate account.

Objective: Write a post for {{PLATFORM — e.g. LinkedIn, X, Instagram}} announcing or discussing {{TOPIC}}.

Context: The audience follows this account for {{WHY THEY FOLLOW — e.g. practical advice, behind-the-scenes updates}}. The tone is usually {{TONE — e.g. direct and a little informal}}.

Constraints:
- Match {{PLATFORM}}'s typical length and formatting conventions
- No more than one exclamation mark in the entire post
- Do not use generic openers like "Exciting news!" or "We're thrilled to announce"
- Include one specific, concrete detail rather than a vague claim

Output format: Return the post text only, plus up to 3 relevant hashtags on a separate line if the platform commonly uses them.

Before finishing, check the post against the constraints above, especially the banned generic openers.

Example

Input

BRAND OR PERSON'S: our
PLATFORM — e.g. LinkedIn, X, Instagram: LinkedIn
TOPIC: launching a free weekly changelog email
WHY THEY FOLLOW — e.g. practical advice, behind-the-scenes updates: practical product and engineering updates
TONE — e.g. direct and a little informal: direct and a little informal

Output

We've started a free weekly changelog email: one email a week, listing exactly what shipped in the product that week. No fluff, no "big things coming soon."

It's the same practical product and engineering detail we share here, collected in one place, so you don't have to catch every post to keep up with what's changed.

If you'd rather read one short weekly summary than dig through release notes, the sign-up link is below. It's free, and you can unsubscribe whenever you like.

Why it works

  • Naming the account's actual tone and reason people follow it gives the model something concrete to match instead of a generic corporate voice.
  • Banning cliché openers like 'Exciting news!' is more effective than asking for 'authentic' tone, which every model interprets differently.
  • Requiring one concrete detail (six changes, dark mode) anchors the post instead of a vague benefit claim.

Why the basic version fails

“Write a LinkedIn post about our new feature” produces the same three sentences every company posts: an exclamation-mark opener, a vague benefit claim, and a call to action with no specifics. It reads like a template because it is one.

What this prompt fixes

Naming the account’s actual tone and reason people follow it gives the model something to match instead of defaulting to generic corporate voice. Banning the specific cliché openers is more effective than asking for “authentic” tone, which every model interprets differently.

Tips per model

  • Grok tends to lean informal by default — useful for platforms like X, but check it hasn’t gone too casual for a professional context.
  • Claude follows the “one concrete detail” constraint well, which tends to be the single biggest improvement over generic social copy.
  • If the output still sounds generic, the tone description is usually too vague — “friendly” applies to almost any brand, while “direct and a little informal, never salesy” gives the model something to actually distinguish.
