PostCreator

Mac app · One-time payment

Your Instagram posts, always on brand. You just write.

Colours, type, logo, tone of voice and the things you never say: set them once, and after that they're on everything you make. For people running a business without a designer.

macOS 12+ · Apple silicon Mac · no account, no subscription

The hard part is already done

Three design decisions. You make them once, and that's that.

Three steps. The middle one repeats.

From the brief to the finished PNG without switching windows.

  1. Describe your brand

    Who you talk to, how you sound, and what you never say. Type it in or paste something you already have.

    5 blocks · nothing goes in until you say so

    The brand and voice block of the brief: name, language, tone as tags, context and notes.
  2. Ask for the post

    A one-line request and how many slides. If your brand brief already names the topic, not even that.

    up to 4,000 characters · 1 to 10 slides · it tells you which template it picked, and why

    The brief field with the project's content pillars underneath, offered as buttons.
  3. Tweak and export

    Every field counts down against the template's real limit. When it all fits: PNG, JPEG or ZIP.

    The corner of the post over the canvas checkerboard, next to the panel marking it ready to export.

✨ Tell the photo what you want

Open the image, ask for a change in plain words, and your ChatGPT edits it. Every version stays; nothing lands in the post until you accept.

PostCreator's image editor: a person holding a phone, the versions on the left, the request on the right, and the AI working on a third change.

Shown as it happens in the app; the picture stays the same because this is a demonstration.

Before you buy

What you need, what happens on first launch, what it won't do.

What you need

  • A Mac with Apple silicon, M1 or later

    Intel Macs won't run it, and Rosetta doesn't help: it translates Intel to ARM, not the other way around
  • macOS 12 Monterey or newer

    Anything older won't even start
  • 1.2 GB of disk once installed

    One file to download. Everything it needs is inside it
  • Your own ChatGPT account

    The AI isn't included: you connect it from inside the app and your own subscription pays for it. Connect nothing and it still works, with a local writer whose text you'll want to go over first

The first time you open it

  • Drag it into Applications

    One .dmg file: mount it, drag it across, done
  • Double-click, like any other app

    Signed with an Apple Developer ID and notarized by Apple: macOS opens it with no warnings
  • A few seconds to start up

    The icon bounces in the Dock while the app starts its internal engine. Normal — it isn't stuck
  • No account, no activation

    No licence keys, no sign-up: it opens and you work

What it doesn't do

  • No posting or scheduling

    You get the files and you upload them yourself. There's no calendar and no queue
  • No video, animation or Reels

    The «9:16» is a still image
  • Instagram sizes only

    No LinkedIn, no X, no Pinterest, no web banners
  • No accounts, cloud or team

    Everything lives on your disk. And you can't upload your own corporate typeface: you pick from the 77 built in

You pay once

No subscription, no account, no renewal email to cancel next year.
