Brand and knowledge

Brand and knowledge holds two things: your brand identity (its name and aliases) and the knowledge base that grounds every piece of AI content and fact-checking MentionFlow does for you.

What it does

It gives the content and fact-checking agents a single source of truth about your brand, so drafts stay accurate to your facts and never drift into claims you don't want to make.

How to use it

• The knowledge base is a structured fact sheet: nine fields, each with a per-field character cap, and lists holding up to 40 items. The content agent treats it as ground truth — it never invents facts and never contradicts your "never claim" list.
• You can auto-generate a first draft of the fact sheet from your own website, but it is always shown for review before saving.
• A separate knowledge library holds longer documents. These are chunked and embedded, then retrieved (top 5 by similarity) at draft time, degrading gracefully to the fact sheet when nothing matches.

How it's computed

Brand context is always resolved through a scoped lookup. The active-brand cookie is attacker-controlled, so it is never trusted on its own — the lookup is scoped to your workspace, which guarantees you only ever see your own workspace's data.

At draft time, the library's longer documents are matched by embedding similarity and the top 5 are pulled in as context; when nothing clears the bar, generation falls back to the structured fact sheet rather than reaching for unrelated text.

Danger Zone: archive and delete

The Brand hub is also where a brand's lifecycle ends, for owners and admins:

• Archive (soft) — collection stops, and the brand immediately frees its project slot, its prompts' pooled quota, and its monitors' engine slots. Every answer and metric is kept: the brand stays in the switcher and the API with an archived badge/flag, its history stays truthful wherever it renders, and it's excluded from Portfolio blends by default with an explicit show-archived toggle. Restore re-checks each of those quotas first and refuses with the numbers if they've been re-spent — archiving is never a quota loophole.
• Delete (hard) — typed-confirmation (the brand's name), then a permanent cascade of the brand and everything under it: prompts, answers, mentions, citations, metrics, competitors, monitors. Audit-logged; cannot be undone.

Limits

The fact sheet is bounded by its per-field character caps. The knowledge library's embedding and retrieval require an OpenAI key; without it, retrieval degrades to the fact sheet alone.
