Tools · AI caption generator
An AI caption generator in your voice.
Most caption tools spit out one line and let you paste it everywhere. That's not how feeds read. We start from your brand kit's voice — extracted from your URL — and turn one idea into a native caption and hashtags for each of four platforms, phrased the way that platform actually reads.
Generate mine →What you get
Captions that sound like you.
Every caption is written from the same brand voice and tuned to the platform it's going to, so you stop rewriting one line four times before it fits.
One idea, four captions
Describe the post once and get a native caption for Instagram, TikTok, LinkedIn, and X — each phrased for its feed, not one line copy-pasted across all of them.
Your brand voice, applied
Captions are written from your brand kit's voice — tone, characteristics, vocabulary, and banned words — so they read like you wrote them, not a generic assistant.
Hashtags per platform
Each caption ships with hashtags tuned to its platform, so the post is ready to publish instead of needing a separate hashtag pass afterward.
Reddit publishing: coming soon
Reddit drafts use their own voice and format. Connecting an account, scheduling, and automatic publishing to Reddit are coming soon.
No accidental repeats
The Originality Engine embeds each angle and drops anything within 0.85 similarity of your history, so your captions don't start echoing each other over time.
Ready to schedule
Captions attach to the post and flow straight into the calendar, scheduled across platforms via Postforme with live status as each one publishes.
How it works
One idea in. Four captions out.
Start from your voice
Your brand kit, extracted from your URL, carries the voice: tone, characteristics, vocabulary, and the words you'd never use.
Describe the post
Type the idea once and pick which of the four platforms you want captions for. No need to phrase it four different ways yourself.
Get a caption per platform
The pipeline writes a native caption and hashtags for each available platform from the same idea, in your voice.
Review, then schedule
Every caption is editable. Approve and schedule across platforms; live status confirms delivery as each one publishes via Postforme.
