Search Brief by PayAPI

Turn a keyword into a writer-ready content brief for search and AI answers.

What it does

Give it a target keyword and who you write for. It returns a content brief a writer can start from: search intent, three title options, a meta description, an H2 and H3 outline, the questions the page should answer directly, terms to cover, a suggested length, and ideas for internal links. It does not pull live ranking data; it plans from the keyword and your notes.
