Why one post for five platforms does not work
The same announcement lands completely differently depending on where it goes. LinkedIn rewards a longer opening that earns the click on the more link, and a professional framing. X needs the point in the first line because there is no room for a runway. Instagram is written under an image and reads as a caption rather than a statement. Threads sits between conversational and casual. Facebook tolerates length but expects a warmer register than LinkedIn.
Pasting one text into all five means at least three of them read wrong. The version that works on LinkedIn is too long and too formal for X. The version that works on X is too thin to justify a LinkedIn post. That is the entire reason this workflow exists as one run with five outputs rather than as a single caption generator.
The output arrives as separate labeled sections, one per platform, so you can copy each one where it belongs without untangling a block of text.
- LinkedIn: a longer hook and a professional frame
- X: the point in the first line
- Instagram: written as a caption under an image
- Threads and Facebook: conversational, with more room
Presets and how to brief it
Five presets shape the run. Launch post pack is the default and covers announcing something new. Cross-platform announcement is for news that is not a launch. Thought-leadership post set turns a point of view into posts. Event promo post set covers a date people need to show up for. Feature update pack is aimed at short captions about an incremental change.
The brief is what you are announcing and why it matters. The vaguer that is, the more generic the posts, and generic social copy is worse than no social copy. Say what changed, who it changes things for, and what you want the reader to do.
The source material field is where you paste the release notes, the blog post, the changelog entry, or the landing page copy. That is what gives the posts something concrete to say. Audience and tone shape the register: a post aimed at engineers and a post aimed at founders about the same release should not sound alike.
What to do with the output
Edit before posting. The strongest single edit is the first line, because that is what decides whether anything after it gets read, and it is the line most worth making specific to something only you could say. Replace generic openings with a number, a result, or a concrete detail from your own work.
Cut length wherever you can. Generated social copy tends to run long and to include a sentence explaining what the post is about, which readers do not need. The second draft is almost always the first draft with the first sentence deleted.
On mechanics: a free signed-in account is required and each run uses AI credits from the monthly allowance. The result is not streamed, so it arrives complete after a few seconds. Everything you enter and everything returned is stored in your account run history until you clear it, so keep unreleased material out of it.
- Rewrite the first line of every post yourself
- Cut the sentence that explains what the post is about
- Inputs and outputs are stored in your run history
