Idlen is a passive income platform for developers that monetizes AI wait time by displaying relevant ads while using coding assistants like Claude, ChatGPT, and Cursor.
What is Idlen?
Idlen is a browser and editor extension that turns the time your AI assistant spends generating code into a revenue stream. It runs as a VS Code extension or Chrome extension (also available for Firefox) and works with Claude, ChatGPT, V0, Bolt, Lovable, Cursor, Windsurf, and Replit. The extension shows non-intrusive, developer-focused ads only during AI processing, so there’s no impact on your workflow. Idlen is built by the Idlen team and claims 50,000+ creators already earning passive income.
Key Features
- Passive Income — Earn €20–100/month per user by allowing relevant ads to appear while AI tools generate responses. Payouts are made via Stripe, PayPal, or a 10% bonus as API credits.
- Zero Latency — Ads load only during the AI wait time, so there’s no additional delay for the user. The extension itself does not slow down your editor.
- Privacy First — Your source code never leaves your machine. The extension performs a local analysis of your package.json to determine relevant ad categories, then makes an anonymous ad request. Full privacy policy here.
- Wide Compatibility — Works with VS Code, Cursor, Chrome, Firefox, and all major AI coding assistants including Claude, ChatGPT, V0, Bolt, Lovable, Windsurf, and Replit.
- Flexible Payouts — Choose between Stripe, PayPal, or a 10% bonus in API credits. Team support allows a shared earnings pool.
- Transparent and Auditable — The extension code is available for security review, and the company publishes its privacy practices.
- Advertiser Platform — Advertisers can reach developers with native, contextual ads inside AI conversations. See ad formats.
- Publisher SDK — AI app builders can monetize their products with 3 lines of code, earning a 70% revenue share. Learn more here.
Who is it for?
- Individual developers who regularly use AI coding assistants and want to offset subscription costs (e.g., ChatGPT Plus, Claude Pro) or earn side income without changing their workflow.
- No-code builders using tools like Lovable or Bolt who can earn passively on every AI request.
- Indie hackers and freelancers who spend multiple hours daily coding with AI and want to turn that idle time into a recurring revenue stream.
- Development teams who want a shared earnings pool to fund team subscriptions or tools.
What can you do with Idlen?
- Offset AI subscription costs: Use Idlen earnings to cover monthly fees for ChatGPT Plus, Claude Pro, or V0 Premium. The calculator suggests you can even generate surplus pocket money (e.g., 150% coverage shown for 4h/day coding).
- Earn passive income while coding: Install the extension, use AI tools as normal, and watch earnings accumulate automatically. No extra clicks or actions required.
- Monetize an existing AI product: If you’re building an AI app, integrate Idlen’s publisher SDK with 3 lines of code to show ads and earn 70% revenue share, paid monthly.
- Discover new developer tools: The ads shown are curated developer tools (cloud hosting, databases, APIs, dev tools) that may be genuinely useful, reducing the annoyance of traditional advertising.
How does Idlen work?
- Install the extension – Add Idlen to VS Code (or Cursor) or install the Chrome/Firefox extension. It works with any AI tool accessed from those environments.
- Use AI as usual – Continue coding with Claude, ChatGPT, Cursor, or any supported AI assistant. No changes to your workflow are needed.
- Earn passively – During the time the AI is generating a response, Idlen shows a relevant ad. Earnings are credited to your account based on ad impressions and fill rates.
A demo video on the site (visible in the VS Code interface screenshot) shows a chat interaction where clicking “Send” triggers the earning process.
Pricing
Idlen is free for end users. There are no subscription fees for installing the extension. Advertisers pay for ad placements, and app builders who use the publisher SDK receive 70% revenue share on ad earnings. The platform operates on a freemium model for advertisers and publishers, with earnings paid out monthly.
FAQ
Is my code safe and private?
Yes. The extension never reads, stores, or transmits your source code. It only analyzes your package.json file locally on your machine to determine which ad categories are relevant, and the ad request is anonymous. The code is open for security review.
Will Idlen slow down my editor?
No. Ads are loaded only during AI processing time, so there’s no impact on editor performance. The extension itself is lightweight and runs only when an AI tool is generating a response.
How do I get paid?
You can choose payout via Stripe, PayPal, or receive a 10% bonus in API credits. Payouts are processed monthly once you reach a minimum threshold (not explicitly stated, but likely standard practice). Teams can set up a shared earnings pool.
What ads will I see?
Only relevant developer tools and services appear — no spam or clickbait. Ads are contextual based on the packages in your project, including categories like cloud hosting, databases, APIs, and dev tools.
Which AI tools are supported?
Idlen works with Claude, ChatGPT, V0, Bolt, Lovable, Cursor, Windsurf, and Replit. It supports VS Code, Cursor, Chrome, and Firefox, so any AI tool accessed from those environments is covered.
