Question: I need a secure and private AI assistant that's available 24/7 to answer my questions on science, technology, and more.

One of the top options is Private LLM, a local AI chatbot for iOS and macOS that works without a network connection or subscription. It supports a variety of open-source LLM models, including grammar correction, summarization and text expansion in multiple languages. The app uses advanced quantization techniques to get the best model performance and speed up text generation, and it's geared for individuals and families who want to get more done and be more creative without sacrificing privacy.

Another top pick is Kin, a personal AI that's designed to be private and secure because it doesn't store or collect any user data. Kin is available 24/7 and uses edge ML and confidential computing for low latency and high security. You can use it to get advice, discuss issues, get inspiration and optimize your time, making it a useful virtual companion for handling the ups and downs of life.

Last is Quivr, an open-source personal productivity assistant that indexes documents, tools and databases with a unified search engine. Quivr uses retrieval-augmented generation to offer a private and local alternative to OpenAI's GPT models. It supports a variety of GenAI models for different tasks, and it's got features like AI-powered search, customizable prompts and integration with files and apps. That makes Quivr a powerful tool for getting work done and finding information privately and quickly.
