Verdicts for all professionals
ChatGPT
▼ MoreThe most versatile general-purpose AI tool with the strongest data analysis capabilities. Enterprise tier resolves most governance concerns but requires active management.
Claude
▼ MoreThe best choice for knowledge-intensive professional work. Strongest document handling, reasoning, and writing quality of any tool on this list. The default pick for any professional whose output is words.
Gemini
▼ MoreBest choice for organisations running on Google Workspace. Unmatched native integration with Docs, Sheets, and Gmail, plus the largest context window in the category. Slightly behind Claude and ChatGPT for the most demanding professional reasoning tasks.
Perplexity
▼ MoreThe best choice when citations and live web sources matter more than polished prose. Purpose-built for research workflows. Pair it with Claude or ChatGPT when the work shifts from research to drafting.
Microsoft Copilot
▼ MoreThe default choice for Microsoft 365 organisations, especially in regulated industries. Best-in-class enterprise governance and Excel integration. Pair with Claude for heavy reasoning and Perplexity for cited research.
Scoring methodology
Scores (1-5) reflect editorial assessment based on published model capabilities, data handling policies, and testing across professional use cases relevant to Australian knowledge workers. WC and GRC scores assess suitability for Australian workers compensation (SRC Act/Comcare) and GRC (APRA, ASIC, FAR) contexts specifically. Scores are current as of April 2026 and will be updated as models evolve. This is general information only. Evaluate tools against your specific requirements and organisational governance framework before deploying.
