Advertisers
An ad network for AI users
LLM advertising, here, means buying the moment someone waits on a model. The ad is a native card. It is not a line written into the answer.
Who you can reach
Anyone using a supported AI chat or editor: ChatGPT, Claude, Gemini, Perplexity, Lovable, Bolt, v0, Replit, and VS Code, including Cursor and Windsurf. Also people in apps that installed the chat SDK.
Developers are part of that audience. So is everyone else waiting on an answer. The extension is opt-in.
What you are buying
One ad per wait. In the browser it is a native card. In the editor it is a placement beside the work. In another app it is a sponsored recommendation, a contextual link, or a CTA card.
OpenAI already sells ads inside ChatGPT. Idlen is the network for the wait itself, including chats that do not sell their own ads.
In the editor you can target by the technologies in the project. You can also target by AI tool and by country. You do not receive the prompt.
Current scale
Over the 30 days to 30 October 2026: 111,528 ad impressions and 2,366 active users. Treat that as the size of the network on that date.
How a campaign starts
Create an advertiser account, pick CPM or CPC, and set the bid. Budgets start at €10. You can set a daily cap. Billing is Stripe, prepaid, and you can pause at any time.
Put in €50, get €100
The first deposit of €50 or more adds a €50 bonus to the organisation wallet, once. A smaller first deposit does not use it up.
