TRI Score

94.2

Exceptional

#1 Best AI Assistants

Overview

Our assessment

ChatGPT remains our highest-ranked general assistant. Its advantage is breadth: writing, research, analysis, coding and multimodal work are unusually strong inside a single product, and the ecosystem around it removes most integration work. Claude performs better on document-heavy workflows; Gemini is the better choice for people already living inside Google.

Best for

  • Everyday knowledge work
  • Teams that want one tool instead of five
  • Research with follow-up questions

Not ideal for

  • Very long document review
  • Organisations that need EU-only data residency
