AI conversations are the new search box. We make them a fair place to advertise.
tehil.io is a contextual advertising platform built for AI conversations. We help advertisers show up at the exact moment someone describes what they need, and we help AI chat publishers turn that moment into revenue, without degrading the answer their users came for.
Why we exist
People no longer type three keywords into a search bar. They explain their situation to an assistant: where they are going, what they need, what they have already ruled out. That conversation holds more intent than any page view ever did.
Yet most AI chats today are a pure cost for the companies running them, and advertisers have almost no clean way to be part of those moments. We built tehil.io to connect both sides with one rule: a sponsored answer must be useful, relevant and clearly labeled, or it should not appear.
What we do
- For publishers: a lightweight SDK that adds contextual sponsored answers to an existing AI chat, or a custom chat we build and run for free, with monetization already inside.
- For advertisers: one campaign that runs across our network of AI apps and on ChatGPT Ads, through our API connection.
- For both: transparent reporting on what was shown, where, and what it earned or delivered.
What we believe
- Context over keywords. We read intent, timing and where the user stands in a decision, not isolated words.
- The answer comes first. Sponsored content never rewrites the AI's answer. It sits beside it, labeled.
- Privacy by design. Conversations are processed to pick a relevant ad, not to build profiles.
- Publishers stay in control. They decide where ads appear, which categories to block and how many to show.
Who is behind tehil.io
tehil.io was founded by Stéphane Pitoun, a serial adtech and SaaS entrepreneur with two successful exits: Bidshake, acquired by Voodoo, and Adxperience. After years building ad technology for mobile and the web, he started tehil.io to bring the same performance discipline to the conversational era, with better standards for users.
Founding publishers program
We are onboarding a limited group of founding publishers with priority support and preferred terms. If you run an AI chat, or want one, we would like to hear from you.
