I got tired of my AI conversations living on someone else's server. So I built an offline alternative. It's free and open source. (Use Stable Diffusion on your phone)

Developer Ali Chherawalla has released a free, open-source mobile app designed to address growing privacy concerns with cloud-based AI services like ChatGPT and Claude. The app, now available on GitHub, the App Store, and Google Play, allows users to run large language models (LLMs), generate images with Stable Diffusion, transcribe audio with Whisper, and use vision AI—all entirely on-device with zero internet required after the initial model download. This approach transforms a smartphone into a self-contained AI workstation, enabling private journaling, sensitive medical or legal queries, and proprietary work brainstorming without the risk of data being stored, analyzed, or used for training on external servers.

The technical implementation leverages on-device inference to process all AI tasks locally, a significant challenge given the computational and memory constraints of mobile hardware. The app is MIT-licensed, ensuring transparency and community development, and operates with no subscriptions or accounts. This shift to local-first AI provides a concrete alternative for professionals and individuals who need to work with confidential information or simply desire true ownership of their digital thoughts, mirroring the privacy and immediacy of a physical calculator.
