nilGPT
nilGPT is a privacy-focused AI chat companion that emphasizes secure, anonymized interaction. It claims that all data is handled with “data private by default”, your chat inputs are split and stored across multiple nilDB nodes, and AI models run inside secure enclaves, so your data isn’t centrally exposed. nilGPT offers specialized conversation modes (such as wellness, personal assistant, companion) to adapt to different use cases. It positions itself as a place where users can “talk freely” about sensitive thoughts or personal topics without fear of log retention or surveillance. It provides both a browser chat interface and app access, with options to sign in or chat anonymously. According to its GitHub repo, nilGPT is built using “SecretLLM + SecretVaults” and is open source under the MIT license.
