Turn notes into a scheduled carousel
Give your assistant notes, a thread or an outline. It plans 5 to 8 slides, renders them as images on your computer, uploads them to Socialync, and schedules one carousel to Instagram, LinkedIn, Facebook and Threads after you approve.
Works on the free plan. Connect an assistant first if you have not: setup guides.
The prompt
Turn these notes into a 6 slide carousel, render it, and schedule it to Instagram and LinkedIn for Thursday 11am my time. Show me the slide text first, then the finished slides and captions before you schedule anything. [paste your notes here]
Swap in your own details. Example links and names are placeholders.
What the assistant does
Each step names the Socialync tool the assistant calls. A step with no tool is the assistant's own work or yours.
- 1
Plan the slides
Your assistant writes 5 to 8 slides. Slide 1 is the hook and the last slide asks for one action. Each slide carries one idea in 25 words or fewer. You get the numbered text and can edit it before anything is rendered.
- 2
Render the images
It renders each slide at 1080 by 1350 pixels, the same size for every slide, as PNG or JPEG. This runs on your computer, which is why the assistant needs to run code and write files. It checks that the text sits inside the frame.
- 3
Check accounts and allowance
It picks the brand, confirms the target platforms are connected and reads your plan.

Upload the slides
It asks Socialync for one upload link per slide, sends each file to its link, then finishes the upload. Socialync returns a single media id that carries every slide in order. Up to 10 images, 25 MB each, and the links last one hour.

Write captions and check the post
Shared text goes in the caption and each platform's own version goes in a per-platform override. Hashtags or a link can go in the first comment. Validation checks image count and aspect ratio per platform.

Show the post and wait
You see the slide list, each platform's caption, the first comment and the local time.
- 7
Schedule it
On your yes it schedules the carousel with the media id, or approves the draft it was holding. To post soon, schedule it a few minutes ahead. Then it lists the calendar to confirm.

What you will be asked to confirm
- The slide text, before any image is rendered.
- The finished slides, each platform's caption, the first comment and the time.
- The yes that schedules it. Any change shows the post again.
Socialync tells your assistant to show you the exact post and wait for your yes in the chat before it publishes, schedules, replies or cancels anything. The publishing tools are marked as destructive, so clients that honor that also ask you to allow each call. You can switch on a confirmation dialog on the API Keys page that shows the exact post inside clients that support it. Socialync records who approved each post and when.
What you need
Plan
The free plan works and the carousel is one post against your 5 a month. Paid plans have unlimited posts.
Connected accounts
Instagram, LinkedIn, Facebook or Threads connected in Socialync.
Assistants
An assistant that can run code, write image files and reach the internet, such as Claude Code, Codex or Cursor. A plain chat window without code tools cannot render and upload the files.
Also
- Your notes, thread or outline pasted into the chat.
Example result
Illustrative example with made-up posts and numbers. It does not come from a real account, and yours will use your own content.
A six slide carousel, ready to schedule
| Slide | Text |
|---|---|
| 1 | Five habits that keep a posting schedule alive |
| 2 | Pick the day before you pick the topic |
| 3 | Write in one batch and let the schedule post |
| 4 | Keep one post format you can make in ten minutes |
| 5 | Review once a week and change one thing |
| 6 | Pick one habit and start this week |
Limits that shape this recipe
- Instagram, LinkedIn, Threads and Facebook take the whole carousel. LinkedIn takes up to 9 images.
- X and Bluesky publish only the first 4 images, so include them only if the first 4 slides work alone.
- TikTok photo posts are not part of this recipe.
- If your assistant cannot reach Socialync's upload server, it will say so. You can add the slides in Socialync by hand (start a post and add the files), then ask the assistant to schedule them from your media library.
- Images can be JPEG, PNG, WebP or GIF.
Connect your assistant first
You add Socialync once and sign in with your Socialync account. Then paste the prompt above. Setup guides:
