Cassidy is an AI platform built for regulated industries and high-stakes work. It is the stronger pick when a process needs an audit trail at every step, governance and control, and the right model for each step. A chat app or ecosystem-bound builder is the better pick when you mainly need quick, simple chat or your automation stays inside one vendor's stack. However, it is important to note that the same chat experience and underlying models are available inside Cassidy's secure environment as well. Each comparison on this page shows where Cassidy overlaps with a platform and where it differs.

Cassidy routes any Agent or Workflow to OpenAI, Anthropic, Google, or open source models, and lets you switch per step. Most single-vendor chat tools, including ChatGPT Enterprise and Claude Enterprise, run exclusively on their own provider's models.

For quick, simple team-wide chat, drafting, and research, a chat app is fine. For work that needs audit trails and control, such as insurance, manufacturing, professional services, and more, choose a platform built for automation, like Cassidy.

Each page is built from each vendor's own documentation, pricing pages, and release notes, cross-checked against review sites and other independent sources, then sense-checked by Cassidy product and solutions leads against our team's own experience with these products, what we hear from prospects, and feedback from former users who are now customers. See the Comparison Methodology module on any individual comparison page for details.

Pages are refreshed when a vendor ships a material change. The "updated" date at the top of each comparison reflects the last verification pass.
