How does an AI post generator keep content sounding on-brand?
By storing a brand profile instead of relying on the prompt. supapost analyses your site or social profile once and saves voice, tone, audience, and content themes to your workspace. Every generation applies that profile automatically, so output stays consistent across platforms and across months without re-prompting.
The second half is format. A post that works on LinkedIn fails on X, because the hook, length, and rhythm are different. Content is generated against the target platform rather than written once and truncated, which is why the same topic reads natively in four places.

Creator questions
Will AI-generated posts sound like me or like a robot?
They sound like you when the brand profile is set. supapost reads your website or social profile and extracts voice, tone, audience, and recurring themes, then applies that profile to every generation. Output is also shaped by patterns from posts that actually performed, not generic template phrasing.
Which platforms can I generate posts for?
X, LinkedIn, Instagram, and Facebook, each with its own formatting rules: 280 characters and a hard hook for X, story-driven paragraphs for LinkedIn, emoji and hashtag blocks for Instagram, conversational framing for Facebook. Blog articles and email newsletters are available on Pro and above.
How many posts can I generate on the free plan?
Ten social posts a month, across all four platforms, plus 50 API requests a day and brand voice detection. No credit card is required. Pro raises it to 100 posts a month and adds blog, newsletter, image generation, and content repurposing.
Can I turn one blog post into posts for every platform?
Yes, that is what the repurpose endpoint does. Send existing content and a target platform, and it returns a native version rather than a truncated copy. One article becomes a LinkedIn post, an X thread, an Instagram caption, and a newsletter section without rewriting each by hand.
Do I need to know how to code to use it?
No. The composer in the dashboard generates posts through a normal interface, no code involved. The API exists for people who want to automate, but nothing about the product requires it. Creators typically use the composer and never touch an endpoint.
