PostNitro for ChatGPT — write, design and post without leaving the chat
You already draft your posts in ChatGPT. Then the work stops: copy it out, open a design tool, rebuild it in your brand, export the slides, open a scheduler, upload, write the caption again. PostNitro removes all of that. Ask ChatGPT for the post and a designed, on-brand carousel comes back — scheduled, if you want it scheduled.
Install from the directory, sign in, done. No design tool to learn and no API key to find.
You write
In the chat, like always
You get
A designed post, not a draft
In your
Fonts, colours and logo
Posted to
LinkedIn, Instagram, TikTok, Threads
Three clicks and a sentence
You do this once. After that it is just part of ChatGPT.
1
Install it from the directory
Open the PostNitro listing in ChatGPT and press Install. One click.
2
Sign in to PostNitro
A normal sign-in page opens. Approve access and the two are linked — nothing to copy, paste or configure.
3
Ask for a post
“Turn this article into a LinkedIn carousel.” That is the whole interface. Slides come back designed in your brand.
What comes back
Not a description of a post. The post — sized, laid out, branded, and ready to publish or download.
Carousels for the feed
Give it a topic, paste an article, or hand over slide copy you already wrote. It writes what is missing, lays out every slide, and applies your brand.
Single images when slides are too much
An announcement, a quote card, a stat graphic. Same templates, same brand, one frame.
Short video for Reels and TikTok
Your slides become scenes in a vertical video, five to sixty seconds, with a track over the top. It is how a carousel reaches TikTok at all.
Pictures that belong to the post
Ask for visuals and it writes the image brief itself, then generates them into the design — behind the text or beside it, not bolted on afterwards.
It looks like you, not like a template
Your fonts, your palette, your logo, your headshot. Set the brand kit up once and every post afterwards is recognisably yours before anyone reads a word.
Or hand it back for a tweak
Ask for an editable design instead of finished files and the deck opens in the PostNitro editor, so you can nudge a headline before it goes out.
Things worth trying first
Say it the way you would say it to a person. No commands to memorise.
Make me something
“Turn this article into a LinkedIn carousel and send me the PNGs.”
“Make an Instagram carousel about three pricing mistakes SaaS founders make.”
“Build a carousel from my notes below, with an intro and a closing slide.”
Put it out for me
“Schedule that for Monday at 9am on Instagram and LinkedIn, with a caption for each.”
“What have I got going out this week?”
“Post this one to my Instagram story as well.”
Set it up how I like it
“Use my dark brand kit from now on.”
“Which of my social accounts are connected?”
“Show me my templates and pick a clean one for text-heavy slides.”
Don't Just Create Posts — Schedule Them Too
Designing the post is only half the job, so PostNitro now finishes it: schedule posts or save drafts directly to LinkedIn, Instagram, TikTok, and Threads, with per-platform captions and settings. Generate or import a design, attach it to a time slot, and PostNitro publishes it for you — from the API, the MCP server, or the CLI, with no separate scheduling tool.
What installing from the directory means
Short version: it is the easy path, and it is the safe one.
Nothing to install on your computer
It lives in your ChatGPT account, not on your machine. Install it once and it is there next time you open the app.
No API key to hunt for
You sign in to PostNitro the same way you sign in to anything. There is no key to generate, copy, or keep somewhere safe.
Checked by OpenAI first
Plugins are reviewed before they are listed, so you are installing something vetted rather than pasting in a link somebody sent you.
It knows your stuff
Your brand kits, templates and connected accounts come with it, so the first post you ask for already looks right.
What you need before you start
A ChatGPT account that supports plugins
Install from the directory or the plugins section. That is the only setup.
A PostNitro plan with API credits
Posts made through ChatGPT run on Embed API credits — the $10/month add-on on a paid plan, or a Plus plan with credits included. Worth knowing before you install: there is no free tier for this.
Your social accounts, if you want it to post
Connect Instagram, LinkedIn, TikTok or Threads in PostNitro once. Skip it and ChatGPT still hands you the files to post yourself.
Wherever you already use ChatGPT
Install once on your account and it follows you.

The bit people ask about
It only sees PostNitro
Your templates, brands, designs, scheduled posts and connected accounts. Nothing else on your computer and nothing in your other apps.
It asks before it does anything
You see what is about to be created, scheduled or deleted, and you approve it. Nothing goes out behind your back.
Uninstall and it is gone
Remove the plugin in ChatGPT, or revoke it in PostNitro. Access stops the moment you do.
We do not train on your posts
What you make here is yours, treated exactly like anything else in your account.
