Where each platform wins

Each competitor has a real advantage. Here is where each one is the better fit.

When Microsoft Copilot is the better fit

Microsoft Copilot is the better fit for a team that lives mostly inside Microsoft 365 and needs help with individual tasks: drafting a document, summarizing an email thread, building a quick chart in Excel. Its native embedding across Word, Excel, Outlook, and Teams is a real advantage.
Teams usually outgrow it when automation has to cross systems, which can mean Copilot Studio, connectors, Power Automate, and IT support.

When Claude Enterprise is the better fit

Claude Enterprise is the better fit for a company already standardized on Anthropic's models that wants a desktop app with local file access, Claude Code for developers, and a chat tool its team already likes.
Teams usually outgrow it when a process has to give the newest hire and the senior analyst the same result, with every step visible for audit.

FAQ

Find answers to common questions about the platform, security, and getting started. Still have questions? Talk to our team!
Which is best for enterprise teams: Microsoft Copilot, Claude Enterprise, or Cassidy?

Cassidy. It is built for regulated and high-stakes work, with an audit trail at every step, Agents and Workflows in one place, and the right model chosen per step. Microsoft Copilot and Claude Enterprise suit quick, simple team-wide chat, and the same chat experience and models are available inside Cassidy's secure environment, with governed Workflows on top.

Which is best for regulated or high-stakes work: Microsoft Copilot, Claude Enterprise, or Cassidy?

Cassidy is built for regulated industries and high-stakes work such as insurance, manufacturing, professional services, and more. Workflows show every step the AI takes, with RBAC, SSO, and audit logs covering each Agent and Workflow. Microsoft Copilot and Claude Enterprise offer solid admin controls and suit individual productivity, while Cassidy adds Workflows that give every employee the same result.

Which of these platforms lets you choose a different AI model for each task?

Cassidy lets builders choose Claude, OpenAI, Gemini, or open source models for each Agent or Workflow step, and switch without rebuilding. Microsoft Copilot supports OpenAI and Anthropic across several surfaces, with availability varying by license and admin settings, and no Google or Gemini models in Microsoft's published lists. Claude Enterprise runs only on Anthropic's models. Anthropic may also ship new features before Cassidy does, though Cassidy's arrive enterprise ready, with governance in mind.

Can we move our existing agents and prompts from Microsoft Copilot or Claude Enterprise to Cassidy?

Yes, and it is quick. Prompts and agent instructions can be copied out of Microsoft Copilot or Claude Enterprise and recreated in Cassidy, and describing the process in plain language is often enough to rebuild it as an Agent or Workflow. Cassidy's solutions team has experience doing this and helps with the first set, so seats can keep running alongside until you are ready.

Which platform is best for a first enterprise-wide AI rollout: Microsoft Copilot, Claude Enterprise, or Cassidy?

Cassidy. It is the easiest to scale and manage, and you can prompt your way to a working Workflow with our team helping you get it right. Teams can start with the chat experience and models they know, then add auditable Workflows on the same platform. Microsoft Copilot and Claude Enterprise work for quick, simple chat, but scaling past that means more products and consoles, or a single model vendor.

Do Microsoft Copilot, Claude Enterprise, or Cassidy train AI models on company data?

None of the three trains on company data by default. Microsoft says Copilot prompts, responses, and Microsoft Graph data are not used to train foundation models. Anthropic does not train on inputs or outputs from commercial products like Claude Enterprise by default, except thumbs up or down feedback, which admins can turn off. Cassidy never uses customer data to train models, and it is SOC 2 Type II attested, GDPR compliant, HIPAA compliant, and CASA validated.
