The pipeline is the hero surface. It takes a post from research to publication: ground it in your inspiration outliers and brand voice, have the host LLM draft on-brand copy in your own voice, produce the media, assemble the post, and schedule or publish.
The host LLM does the drafting. ContentHero never writes copy server-side. The draft is grounded in your real context and approved by you before anything ships. See the thesis.

​
The five phases

1

Ground

Pull the context that makes a draft on-brand instead of generic:
  • list_outliers (scope with brandKitId) then get_inspiration_content on the top few, for hook archetype, structure, pacing, and CTA style.
  • get_brand_kit for tone, vocabulary, and banned words.
  • get_brand_account_performance for the user’s own top-performing posts.
  • search_brand_knowledge for the brand’s stance on the topic.

Draft (host LLM)

Synthesize a concept, hook, and caption that emulate the user’s proven patterns in the user’s own voice. The user’s own top posts win over a stated profile. Present the draft for approval. Do not invent copy that is not grounded.
3

Produce

Generate the media with the generate surface. A common chain is generate_image for the key frame, then its output id into generate_video as the start frame, grounded in the brand’s visual style.
4

Assemble

create_post with the approved caption, then add_post_asset for the media, then add_post_destination for each platform (format and connected account).
5

Ship

schedule_post for a future slot, or publish_post to go now, only after the user confirms destinations and timing.

​
Connected accounts

Posts publish to connected social accounts. List them with list_connected_accounts and pass the account into a destination. The encrypted credentials behind a connection are never exposed through the API; you reference an account by id.

​
Approval is mandatory

Never schedule or publish without explicit user approval of the final content. Reads and drafts are free; shipping is gated on a yes.
