"Which AI should we use — ChatGPT, Claude, or Copilot?" is one of the questions I get most. The honest answer is that all three are capable, they're improving constantly, and the right choice depends less on benchmarks than on how your team works and where your data lives. Here's a grounded comparison to help you decide.
The short version
- ChatGPT (OpenAI) — versatile, huge ecosystem of integrations, strong for general drafting, brainstorming, and custom assistants.
- Claude (Anthropic) — known for careful, well-structured writing, strong reasoning on long documents, and a measured tone many business users prefer.
- Copilot (Microsoft) — lives inside the Microsoft 365 apps you already use, with your work context in Word, Excel, Outlook, and Teams.
Where each one shines
If you live in Microsoft 365
If your business runs on Outlook, Teams, Word, and Excel, Copilot has a real advantage: it works inside those apps with your existing files and permissions. For many Midwest offices, that "it's already where the work happens" factor outweighs raw capability.
If you want the most flexible assistant
ChatGPT's wide ecosystem and custom assistant features make it a strong general-purpose pick, especially for teams that want to build tailored helpers for sales, support, or operations.
If writing quality and long documents matter
Claude is a favorite for careful drafting, summarizing long contracts or reports, and tasks where you want structured, on-tone output. Plenty of teams use it specifically for client-facing writing.
The questions that actually decide it
- Where does your data live? If you're deep in Microsoft 365, Copilot reduces friction. If not, that advantage shrinks.
- How sensitive is your data? Enterprise tiers offer data protections, but for the most sensitive workloads, a private or on-premise model may be the right call.
- What will people actually use? The best tool is the one your team adopts. Adoption beats benchmarks every time.
You don't have to pick just one
Many businesses we work with use Copilot for day-to-day office work and a second assistant for specialized drafting or building custom tools. The key is a clear policy on what data goes where, and proper enterprise (not free consumer) accounts so your inputs aren't used to train public models.
Don't forget the private option
For regulated or privacy-sensitive Midwest businesses, there's a fourth answer: run a capable open model on your own hardware so nothing leaves your control. We do exactly this on our own local silicon, and it's a core part of our AI consulting work.
