For designers who make monthly social content for brands

Stop rebuilding the same post in six sizes every month

Write a client's brand down once: colours, fonts, type scale, logo and sizes. Plan the month in one sheet the client approves. Then the kit builds every post in every size in the tool you already use, with the brand's own swatches, styles and logo, still fully editable.

  • R249 once-off. No subscription, use it for every client you have.
  • Builds in Illustrator and Figma, with templates for Photoshop and InDesign and a method for Affinity and Canva.
  • Seven AI prompts that turn a brand guide into the brand file and write the month's posts in the brand's voice.

Two posts for a coffee brand, each built in six sizes: portrait, tall, square, landscape, email banner and story
Two rows of the plan, built in one run. A statement and an offer post, each in portrait, tall, square, landscape, email banner and story, in Illustrator. Every size is still fully editable.

Sound familiar? The client sends the month's copy in an email. You design the post, then resize it five times, nudging the logo and rewrapping the headline in every size, checking the brand guide for the hex code you've typed a hundred times. Next month you do it all again.

The kit does the rebuilding, so your hours go into the design.

From brand guide to a month of posts

  1. 1

    Write the brand once

    One file per client: colours by role, fonts, type scale, logo, margins, button shape, sizes, voice. AI prompt 1 writes it from the brand guide PDF and lists what to ask the client.

  2. 2

    Plan the month in one sheet

    One row per post: date, headline, body, button, photo, caption. The client approves rows in the same sheet, and only approved posts get built.

  3. 3

    Build every post

    Run the script or plugin. Every post comes out in every size, laid out for each shape, with real swatches, styles and the logo as a symbol or component.

  4. 4

    Check and hand over

    Refine anything by hand: nothing is flattened. Go through the handover checklist, export, and the next month starts from the same files.

Real output from the test runs

A made-up coffee brand, built in each tool from the same brand file and plan.

A brand library sheet with six colour swatches, the headline, body and button type, the logo and the margin
The brand library. Built from the brand file first, so you can check it against the brand guide before a single post.
Four posts in Figma, each a row of instances in every size, in a section named with the date
Figma. Colour variables, text styles, one component per layout and size, and every post as an instance. Edit a template and every post follows.
Two Photoshop templates and two exported photo posts
Photoshop. Layered templates in the brand's colours and fonts, filled from the plan with Photoshop's own data sets, one PNG per post.

It's for you if

  • You make social posts every month for one or more brands, as a freelancer, a studio or in-house.
  • You use Illustrator, Figma, Photoshop, InDesign, Affinity or Canva Pro.
  • Your clients have a brand guide, or you can write one with them.

It's not for you if

  • Every post you make is a one-off with its own layout. The kit is for posts that follow a system.
  • You need video or animated posts. It builds still posts.
  • You want posts scheduled and published for you. It makes the files and the captions; your scheduler posts them.

Questions

Do I need to know how to code?

No. You edit one small text file per client, brand.json, and AI prompt 1 writes it for you from the brand guide. Running the kit is File > Scripts in Adobe apps, or one plugin window in Figma.

Will every post look like a template?

The kit gives you three layouts (a statement, a photo post and an offer) in the brand's own colours, fonts, logo and button shape, laid out for each size. Everything stays editable: restyle the templates, change any post by hand, and add your own design on top. It does the repetitive part, not the design thinking.

Does it work on the free Figma plan?

Yes. It was tested on Figma's free Starter plan, and uses two pages of the three a free file allows. You need the Figma desktop app to add the plugin.

Can I use it for all my clients?

Yes. Use it for your own work and your clients' work, for as many brands as you like. You can't give the kit's files to clients or anyone else, or resell it.

Mac or Windows?

The kit was built and tested on a Mac. Adobe's scripting and the Figma desktop app also run on Windows. If something doesn't work on yours, email us and we'll fix it or refund you.

What sizes does it make?

Whatever sizes the brand file lists. The example has six: portrait 1080x1350, tall 1080x1440, square, landscape 1920x1080, email banner 600x200 and story 1080x1920. Add or remove sizes in one place. The Export and Handover Pack adds 14 checked sizes for Meta, LinkedIn, email and X.

Which AI does it work with?

The prompts work in ChatGPT, Claude or Gemini. You copy a prompt, fill in the brackets, attach the file it asks for, and paste the answer into the kit. AI gets things wrong, so the prompts ask it to flag gaps, and the guide reminds you to check every fact before it goes to a client.

How do I get the kit after I pay?

Straight away. Your links show on screen after payment and arrive by email from kits@underbridges.co.za: a download for the kit files, and a link to make your own copy of the planner. If you don't see the email, check your spam folder or write to info@underbridges.co.za.

One brand file. One plan. Every post, every size.
