About

Simtheory is an AI-powered workspace designed to transform how teams work by turning conversations into real actions through connected systems, data, and intelligent assistants. It is not just a chatbot, but a secure environment where users can build AI assistants that understand their business context, access internal data, and execute tasks such as drafting reports, analyzing datasets, updating CRM records, scheduling meetings, or sending communications. It connects directly to data warehouses, SaaS tools, and internal systems, giving AI full context to generate accurate, relevant outputs and enabling teams to move from simple prompts to delegated work with measurable outcomes. Users can create shared assistants with custom instructions and knowledge bases, allowing teams to standardize workflows and collaborate more effectively across projects. Simtheory supports multiple AI models in a single workspace, allowing users to switch between them seamlessly.
