PIN AI Launches Mobile App Letting You Make Your Own Personalized, Private AI Model

An anonymous reader quotes a report from VentureBeat: A new startup PIN AI (not to be confused with the poorly reviewed hardware device the AI Pin by Humane) has emerged from stealth to launch its first mobile app, which lets a user select an underlying open-source AI model that runs directly on their smartphone (iOS/Apple iPhone and Google Android supported) and remains private and totally customized to their preferences. Built with a decentralized infrastructure that prioritizes privacy, PIN AI aims to challenge big tech's dominance over user data by ensuring that personal AI serves individuals -- not corporate interests. Founded by AI and blockchain experts from Columbia, MIT and Stanford, PIN AI is led by Davide Crapis, Ben Wu and Bill Sun, who bring deep experience in AI research, large-scale data infrastructure and blockchain security.

PIN AI introduces an alternative to centralized AI models that collect and monetize user data. Unlike cloud-based AI controlled by large tech firms, PIN AI's personal AI runs locally on user devices, allowing for secure, customized AI experiences without third-party surveillance. At the heart of PIN AI is a user-controlled data bank, which enables individuals to store and manage their personal information while allowing developers access to anonymized, multi-category insights -- ranging from shopping habits to investment strategies. This approach ensures that AI-powered services can benefit from high-quality contextual data without compromising user privacy.

The new mobile app launched in the U.S. and multiple regions also includes key features such as: - The 'God model' (guardian of data): Helps users track how well their AI understands them, ensuring it aligns with their preferences. - Ask PIN AI: A personalized AI assistant capable of handling tasks like financial planning, travel coordination and product recommendations. - Open-source integrations: Users can connect apps like Gmail, social media platforms and financial services to their personal AI, training it to better serve them without exposing data to third parties. - 'With our app, you have a personal AI that is your model,' Crapis added. 'You own the weights, and it's completely private, with privacy-preserving fine-tuning.' Davide Crapis, co-founder of PIN AI, told VentureBeat that the app currently supports several open-source AI models, including small versions of DeepSeek and Meta's Llama. 'With our app, you have a personal AI that is your model,' Crapis added. 'You own the weights, and it's completely private, with privacy-preserving fine-tuning.'
