Scorecards

Why each product scored what it did

#1 · Best for writing and contracts

Claude

Claude is the assistant we recommend when the work is reading and writing serious documents. It holds context better across long inputs, and its prose needs less editing than any competitor we score. It trails ChatGPT on breadth of tooling and on casual multimodal tasks.

92.8Exceptional
Capability30%
96

How much the product can actually do, and how well it does the core job.

90

94

Reliability15%
95

Consistency, uptime, support responsiveness and predictable behaviour.

Professional Utility10%
93

How well it fits real professional workflows, not demos.

Momentum10%
92

Rate of meaningful improvement over the last two evaluation cycles.

#2 · Best for google workspace teams

Gemini

Gemini's ranking is driven less by raw capability than by placement: inside Docs, Gmail, Sheets and Drive it removes copy-paste from the workflow entirely. Outside that ecosystem the advantage mostly disappears.

#3 · Best for research

Perplexity

Perplexity is the tool we reach for when the citation matters as much as the answer. It is a research instrument rather than a general assistant, and we score it that way.

#4 · Best for microsoft 365 companies

Microsoft Copilot

Copilot scores as an enterprise decision, not a capability decision. Inside Microsoft 365 with the right licences it is genuinely useful; standalone it is behind every leader in this category.

#5 · Best for real-time monitoring

Grok

Grok's distinct advantage is live access to public conversation, which makes it useful for monitoring sentiment. For document work and professional writing it sits well below the leaders.
