Reach users when they're
asking about you

Cognatu places your ad in an AI conversation at the exact moment a user is discussing your category — not based on cookies or browsing history, but on what they're actually saying right now.

Price auction — never overbid
Brands that win the moment of intent
People increasingly ask AI assistants instead of searching. If your customers make decisions in conversation, Cognatu puts you in that conversation — at the exact moment it matters.
✈️

Travel & booking

Be there at "find me cheap flights to Tokyo." Your offer appears while the trip is still being planned — not retargeted across the web three days after they've already booked.

💰

Finance & investing

Users ask assistants how to budget, save, and invest. Reach them mid-decision with a context-matched placement — no behavioural profiles, no PII, nothing for compliance to worry about.

🎓

SaaS, dev tools & education

From "how do I deploy this?" to "teach me SQL" — put your product inside the answer, in front of developers and learners right when intent peaks.

Your ad, in the right conversation
Traditional display ads interrupt. Cognatu ads are shown when a user is already in a relevant conversation — higher intent, lower friction.
1

Create a campaign

Set your ad copy, targeting rules, and max CPM bid. Takes under 5 minutes via the self-serve dashboard or REST API.

2

Cognatu matches in real time

Each LLM response triggers a 45ms auction. Your campaign competes based on topic relevance, bid, and optional audience signals.

3

Ad appears inline

The winning ad is served contextually alongside the AI response — no popups, no banners, no interruptions.

4

Track and optimise

Impressions, clicks, conversions, and spend — all in your advertiser dashboard, updated in real time.

Precise without being creepy
No cookies. No user profiles. Topic matching runs on the publisher's device — we only see an anonymised signal, never the raw conversation.

Topic targeting

Choose one or more categories. Your ad is eligible whenever the conversation scores above your minimum topic threshold.

🧠

Semantic prompt targeting

Describe your ideal audience in plain English: "user comparing flight prices and looking for travel deals." We match by embedding similarity — no keywords needed.

🔐

ZKP-verified audiences

Target users who have cryptographically proven a demographic or behavioural attribute — without revealing any personal data. Pay a premium, get verified reach.

Second-price auction — you only pay what it's worth
Set a max CPM. You pay $0.01 above the next bidder — never your full bid. No contracts, no minimums, pause anytime.
