Best AI for IT Support
ChatGPT is the versatile first-line tool for IT troubleshooting and automation, Microsoft Copilot is essential for Microsoft-environment IT teams, and Perplexity provides sourced, current answers to fast-moving security and technology questions.
IT support work is a mix of repetitive troubleshooting and the occasional problem that needs current, sourced information fast. ChatGPT covers the repetitive half well: it diagnoses common technical issues step by step, writes troubleshooting runbooks, generates scripts for routine tasks, and explains errors in language an end user without a technical background can actually follow. Microsoft Copilot matters specifically for teams managing Microsoft-centric infrastructure, since its integration with Microsoft 365 and Azure means it already has context on the environment it's supporting rather than needing everything explained from scratch. Perplexity is worth reaching for when the issue involves something time-sensitive, like a new security advisory or a vendor's latest documentation, because it searches current sources and gives you the link, rather than relying on training data that may already be out of date by the time a threat is disclosed.
For a Microsoft-heavy environment, Copilot is the natural default. For anything outside that ecosystem, or for a fast-moving security question, ChatGPT and Perplexity cover more ground.

Frequently Asked Questions
Which AI is best for a Microsoft-heavy IT environment?
Microsoft Copilot, because it integrates directly with Microsoft 365 and Azure and already has context on that infrastructure. Teams outside the Microsoft ecosystem get less benefit from that integration and are usually better served by ChatGPT or Perplexity.
Can AI actually help with security advisories?
Perplexity is the stronger choice here specifically because it searches current sources and cites them, which matters for security issues where the information changes fast and a general-purpose model's training data may already be outdated.
Is ChatGPT good enough for writing troubleshooting documentation?
Yes, this is one of its more reliable use cases: step-by-step diagnostic runbooks, scripts for routine IT tasks, and plain-language explanations of technical errors for non-technical end users all come out usable with light editing.
