Knowledge base

The brand brain every agent runs on.

Brand strategy, tone of voice, audience profiles, competitor angles, approved sources and the rules every agent has to follow. One curated knowledge base - the spine of the entire platform.

A strategy document, not a settings page

Tone of voice, audience, positioning, strategic point of view and the hard rules every agent has to follow. Update one section and the whole platform learns at once.

Built by a strategist, not a quiz

For beta customers, Stefan builds it with you. We work through your business, your customers and your content, and the output is a real strategy document rather than a generic profile.

One source of truth, no drift

Soften your tone, ban a phrase or swap a competitor reference, and it propagates across the blog writer, the social writer, the newsletter writer, the assistant and the PR writer.

How it actually works

Retrieval, not a prompt stuffed with files.

Extraction and chunking. Every document you add is broken into clean, structured sections rather than kept as one long file, so a query can surface the exact paragraph that matters.

Vector search. When an agent writes, it searches the knowledge base by meaning, not keywords. Ask about pricing objections and it retrieves the pricing section even if the word "pricing" never appears.

Tone enforced mechanically. A separate rules layer checks every draft against your hard rules - banned words, formatting, structure - before anything saves, the same linter every agent runs through.

Hard rules, checked mechanically.

You don't have to know what a tone-of-voice spectrum is or how to write a competitor differentiation matrix. That's the bit we handle. What you get is a set of never-use and always-do rules that every agent reads on every run.

Hard rules
CHECKED EVERY RUN
NEVER USE
"game changer", "circle back", "leverage" as a verb
NEVER USE
em dashes - use a spaced hyphen instead
ALWAYS
sentence case for every heading
ALWAYS
Oxford commas, one space after periods
LINTER CAUGHT ONE
Line 14 uses "game changer" - flagged before the draft could be saved.

One workspace, many brands

Run every brand you have from a single workspace.

A founder has a personal brand and the company. An operator runs a couple of side projects. Contengi holds them all in one workspace - each brand with its own knowledge base, tone of voice, audience profile and team. Switch with one click, with nothing drifting between them.

Works with your own Claude too

The same brain, inside Claude MCP.

Connect Contengi to Claude and the knowledge base comes with it. Claude reads your brand strategy, tone of voice and hard rules before it drafts anything, from a normal conversation, not just from inside the app.

FAQ

Common questions

What actually goes into the knowledge base?

Brand strategy, tone of voice, audience profiles, competitor angles, approved sources, and the hard rules every agent has to follow - the same file every Contengi agent reads before it writes a word.

Do I have to fill it in myself?

No. For beta customers, Stefan builds it with you directly, working through your business, your customers and your existing content rather than handing you a form.

Can I run more than one brand from a single knowledge base?

Each brand gets its own knowledge base, tone of voice, audience profile and content library inside one workspace. Switch between them with one click - nothing drifts between brands.

What happens when I change something in it?

Every agent picks it up immediately. Change an audience profile or ban a phrase once, and the blog writer, social writer, newsletter writer, assistant and PR writer all follow it on their next run.
