15 Private ChatGPT Alternatives That Don't Train on Your Data

A Stanford study from October 2025 highlights that user inputs to AI tools like ChatGPT are often used for model training unless users opt out, with a significant portion containing sensitive data. As privacy concerns rise, especially for enterprises, various private alternatives to ChatGPT are emerging. These alternatives prioritize data control and privacy, offering features like local operation, zero-retention policies, and compliance with regulatory standards. Options include Prem AI, which is designed for regulated industries and offers on-premise deployment, and Claude, which provides better privacy controls on paid plans. Other tools like Ollama, LM Studio, and Jan allow users to run open-source models locally, ensuring data never leaves their devices. Platforms like Venice AI offer cloud convenience with local data storage, while Grok provides real-time access to X (formerly Twitter) data. Each solution varies in terms of privacy, setup complexity, and pricing, catering to different user needs from individual privacy-focused users to enterprises requiring data sovereignty.
