Thousands Are Selling Their Phone Calls, Videos, and Voices to Train AI for Quick Cash

A new gig economy is emerging where people worldwide sell their most personal data — phone calls, ambient audio recordings, videos of their neighborhoods, and even their biometric identities — to companies hungry for training data for AI models.
The New Data Gold Rush
Apps like Kled AI, Silencio, Neon Mobile, and Luel AI are paying users small amounts for data that AI companies desperately need. As Silicon Valley’s hunger for high-quality, human-grade training data outpaces what can be scraped from the open internet, these data marketplaces have sprung up to fill the gap.
- Kled AI — Pays users for uploading photos and videos of everyday life. One contributor in South Africa earned $50 in two weeks by recording walks around his neighborhood.
- Silencio — Crowdsources ambient audio data by accessing users’ phone microphones. A student in India earns over $100/month recording city sounds like restaurant noise and traffic.
- Neon Mobile — Pays $0.50 per minute for users’ private phone chats with friends and family. An 18-year-old in Chicago made hundreds selling his personal conversations.
Why AI Companies Need This Data
AI language models like ChatGPT and Gemini are facing a data drought. Researchers estimate AI companies will run out of fresh high-quality text to train on as soon as 2026. The most-used training sources are now restricting access, and feeding AI its own synthetic data leads to model collapse and error-filled outputs.
Real human data — authentic conversations, real-world video, genuine audio — is becoming the most valuable commodity in tech.
The Hidden Costs
The trade-offs are significant. Contributors are fueling an industry that may eventually automate their own skills, while making themselves vulnerable to deepfakes, identity theft, and digital exploitation. When you sell a recording of your voice, you’re potentially giving an AI company the raw material to clone it forever.
The Bottom Line
The logic is grimly rational: tech companies already harvest your data without paying you, so why not get paid? But there’s a difference between a company tracking your browsing habits and literally selling recordings of your private phone calls. This isn’t a side hustle — it’s selling your identity one data point at a time. The $14 you earn recording your feet while walking might be the cheapest your data ever sells for.
