How the AI post generator works

Step 1

Set your brand voice once

In your brand's AI settings, add rules such as tone, words to avoid, emoji use or a sign-off, and tag them for posts. Every draft follows them.

Step 2

Describe the post

Open Generate with AI in the composer, say what the post is about and move the slider to the length you want.

Step 3

Refine it in plain words

Ask for changes like "shorter", "add three hashtags" or "end with a question". Your instruction wins where it conflicts with a brand rule.

Step 4

Apply and schedule

Apply the draft to the composer, add media, adjust per network if needed, then publish now or schedule it.

Prompts that work well

The more specific the brief, the less editing you do afterwards. Say what the post is about, who it's for and what you want people to do next.

Announce our Saturday brunch menu and mention the new vegan pancakes. Friendly, two emojis max.
A LinkedIn post about what we learned shipping our first mobile-friendly checkout. End with a question.
Remind followers that early-bird tickets for the spring workshop close on Friday.
Thank customers for 5 years in business and invite them to share their favourite visit.

Text and visuals in one place

The same composer has a Nano Banana image generator, an embedded Adobe Express editor for touch-ups, and an AI Video button that opens Seedance 2.0. Whatever you generate drops straight into the post.

When a network needs its own version, switch on per-platform editing and adjust the caption on that tab: a longer take for LinkedIn, a tighter one for X.

What it costs in credits

Each generation or edit uses 1 AI credit, the same credit that pays for AI replies. Monthly credits renew with your plan, and credit packs from $5 top you up when you need more.

AI post generator FAQ

Does the AI post generator write in my brand's voice?

Yes. Each draft is written for your brand by name and follows the brand rules you tagged for posts, such as tone, banned words or a standard sign-off. You set those rules once in the brand's AI configuration.

How much does each post cost?

One AI credit per generation and one per edit. Free includes 30 credits a month, Advanced 1,300 and Elite 2,400. Credit packs start at $5 if you run out.

Can I use it for LinkedIn, X and TikTok captions?

Yes. The generator writes the post text, and the composer lets you keep one caption for every network or edit a separate version per account, for example a longer LinkedIn post and a trimmed version for X.

Can I control how long the post is?

A slider sets the target length from about 10 to about 350 words, and the generator is told to finish within it without stopping mid-sentence.

Is there a way to try it without an account?

Yes. The free Instagram caption, LinkedIn post, tweet and post ideas generators on our tools page need no sign-up. The in-app generator adds your brand rules, editing and scheduling.
