Question: I'm looking for a platform that enables secure and private team collaboration using AI chatbots.

Team-GPT is an information retrieval system geared for teams to collaborate and to store knowledge within an organization. It provides 100% private and secure interactions, a chat interface that's easy to use, folders and subfolders for organization, ready-to-use prompt templates, and support for multiple models including GPT-4. The system is competitively priced, with options for up to 500 people, and includes features like personal OpenAI API keys, Azure OpenAI integration, AI editing, image generation, and custom model support.

Another option is Langdock, which is designed to boost team productivity while keeping data as secure as possible. Langdock has a range of features, including a daily chat companion for idea generation and writing, customizable assistants that draw on internal knowledge, and workflows that automate repetitive tasks. It can integrate with other tools and apps, and uses models hosted in Europe and the US. Langdock is certified in several areas, including GDPR compliance, ISO 27001, and SOC 2 Type 2 compliance, for maximum security and privacy.

For a more centralized approach, WorkHub centralizes knowledge management and automates tasks across an organization by linking multiple databases, files and URLs into one interface. It includes WorkBot, a conversational AI that accepts natural language queries, and AI Agents that can perform tasks on their own. WorkHub also has strong privacy controls with role-based access control and compliance regulations, so it can be used in many industries.

Last, Puzzle Studio is a private chatbot-building platform that marries AI with a peer-to-peer knowledge base. It lets teams collaborate without knowledge silos but keeps data in their own control. The platform is LLM agnostic, can be used offline, and can be integrated with web content like sitemaps and RSS feeds. It's a decentralized, cost-effective way to manage a knowledge base.
