Question: Is there a way to use ChatGPT privately, without anyone else seeing my conversations?

Private LLM is an AI chatbot for iOS and macOS that works locally and offers full privacy and offline use. It supports several open-source LLM models, lets you customize system prompts, integrate with Siri and Shortcuts, and use AI language services like grammar checking and summarization. It's geared for individuals and families who want a private, local AI assistant with no network connection or subscription, so it's a good option for private AI use.

Another good option is Quivr, an open-source personal productivity assistant that uses AI technology for unified search across documents, tools and databases. It offers retrieval-augmented generation, a private and local alternative to OpenAI's ChatGPT. Quivr can be connected to files, apps, APIs and databases, and you can customize models and prompt instructions to get the results you want. For extra security, it's got secure deployment options and a community.

If you're looking for a tool specifically geared for privacy and security, GPT Guard is designed to ensure privacy compliance when using ChatGPT. It offers private text generation and privacy-preserving analysis of sensitive data. It's good for generating customer emails, summaries and meeting notes in a private way. It also offers a free trial and enterprise plans with extra features and privacy commitments.
