Idlen

Idlen is a native advertising platform built specifically for developers. It places relevant ads during AI processing moments inside VS Code, Cursor, Windsurf, Chromium browsers, Firefox, and AI chat applications, turning otherwise idle wait time into a natural space for advertising.

For developers, Idlen makes it possible to earn money while waiting for AI responses, so the minutes spent watching a model think no longer go to waste. Advertisers can reach users precisely by their technology stack, which means their messages land in front of the right technical audience instead of being lost in generic channels.

AI app publishers can monetize their chat products with the Idlen SDK, creating a new revenue stream without disrupting the user experience. Idlen states that prompts and source code remain private, with package analysis performed locally to determine ad relevance, so privacy stays intact while ads remain useful.
