Why this social media prompt structure works
Social posts live or die by their first line. On most platforms, only one or two lines are visible before "see more", so the prompt explicitly asks for a hook that still works if everything else is cut off.
The builder also asks for several options with different angles. A question, a bold statement and a short story about the same topic perform very differently, and you can only judge which fits your voice when you see them side by side. Choosing from three drafts is faster than rewriting one.
The platform field does more than you might think. LinkedIn rewards short paragraphs and personal lessons; X needs compression; Instagram captions support the image rather than repeat it. Naming the platform lets the model apply those conventions without you spelling them out. The goal field then shapes the ending: a post meant to start a conversation should end with a genuine question, while an announcement should end with the date and the link.
As with every builder here, the prompt forbids invented numbers and testimonials, which keeps you away from claims you cannot back up publicly.
Worked example
Say you want to share a lesson from a support-tool migration with peers on LinkedIn. These are the inputs:
- Platform
- What is the post about?
- Our team just finished migrating our customer support from email to a shared help desk
- Goal
- share expertise
- Audience
- operations and support leads at small software companies
- Call to action
- Ask readers what tool they use
- Tone
- Professional
- Number of options
- 3
- Hashtags
- No hashtags
- Details and facts
- Took 6 weeks. Biggest lesson: we wrote the saved replies before switching, not after.
The builder turns these inputs into the following prompt. Load it into the form above with the LinkedIn lesson example chip and change anything you like.
You are a social media copywriter who knows how LinkedIn works and writes posts people stop scrolling for.
## Task
Write 3 different LinkedIn post options about: Our team just finished migrating our customer support from email to a shared help desk.
- Goal of the post: share expertise
- Audience: operations and support leads at small software companies
- Call to action: Ask readers what tool they use
## Details and facts
Took 6 weeks. Biggest lesson: we wrote the saved replies before switching, not after.
## Requirements
- Tone: Professional
- Follow the usual length and formatting conventions of LinkedIn.
- Make the first line a strong hook that works even if the rest is cut off.
- Each option should use a different angle (for example a question, a bold statement, a short story).
- Do not use hashtags.
- Do not invent numbers, testimonials or claims I did not provide.
## Output format
Label each option (Option 1, Option 2, ...). After the options, add one sentence on which you would post first and why.This page shows only the prompt. The answer depends on the AI tool you paste it into, so always review the result before you use it.
Tips to improve your results
- Put one concrete detail in the facts field (a number, a name, a lesson). Specific posts beat generic ones.
- Turn hashtags off for LinkedIn and X unless you know they help in your niche.
- Read each option out loud. If it sounds like an advert, ask for a more personal version.
- Ask the AI to rewrite your favourite option in your own voice by pasting two of your past posts.
- Do not post the AI's text unchanged. Add one sentence only you could have written.
Frequently asked questions
Does the AI know the character limits of each platform?
Most models know the general conventions, but limits change. The prompt asks the AI to follow the platform's usual length; check the final text in the platform's own editor before posting.
Can I create a week of posts at once?
Yes. Use the builder for one post, then reply in the same chat with "Now do the same for these topics:" and a list. Review each post separately.
Should I use hashtags?
It depends on the platform and your audience. They are still common on Instagram and TikTok and less important on LinkedIn and X. The builder lets you switch them on or off.
Can it write posts for images or videos?
Yes. Describe the image or video in the topic field. For creating the image itself, use our image prompt generator.
Is anything I type shared?
No. The prompt is built in your browser. Nothing you type is sent to us or to any AI provider until you paste it there yourself.
