What is brief.md?

An open spec for portable brand context. Plain markdown with structured frontmatter; readable by any tool that implements the spec. Your voice, your audience, your do-not-say list. Portable, not locked in our database.

Frequently asked questions

What is brief.md?

brief.md is an open specification for portable brand context: a single markdown file with YAML frontmatter that captures a brand's identity, voice rules, credentials, publications, and assets. The same file works across any tool that implements the spec; AI assistants, journalists, and downstream tooling read the same canonical source.

Do I need a PRAPI account to use the generator?

No. The brief.md generator is free and requires no signup. Paste your starter inputs, get back a valid brand-brief.md you can save, edit in Git, and use with PRAPI or any other tool that implements the spec.

Where should I publish my brief.md?

On your brand domain at /brief.md and /.well-known/brief.md. Both URLs serve the same content as text/markdown so AI assistants and brand-context tooling can fetch it predictably. PRAPI ships a small proxy handler that proxies these URLs to the canonical brief stored in your account.

What goes inside brief.md?

Identity (legal name, founders, mission), voice rules (banned phrases, required elements), brand context (what you do, for whom, why), positioning, visual identity, available assets, and verifiable credentials. Sections are scoped public, pitch-shareable, or private. Only public sections appear in third-party-visible outputs.

Is brief.md the same as llms.txt?

No. llms.txt is a navigation file that points an AI to other content on the site. brief.md is content itself: verified brand context the AI consumes directly. brief.md is structurally a primary source for facts about the brand; llms.txt is a sitemap-style index for crawlers. They can coexist.
