Earn while you work with AI in any IDE or browser
Chrome ExtensionsAdvertisingDeveloper ToolsArtificial Intelligence

Developers wait on AI all day. That wait is an ad slot. One network, three doors. If you code: install the VS Code, Cursor or Chrome extension. A native ad while the model thinks. You keep 70%. We don't read your prompts. If you sell a developer tool: you show up in the IDE and the browser, targeted by the stack they actually use (React, Python, AWS). Pay €200, get €400 this week. If you shipped a chat app: npm i @idlen/chat-sdk. Three lines. Ads optional. No key, no ads. You keep 70%.
