Compare AI assistants for your everyday work

Draft, analyse files and revise everyday work with a human in control.

Research-based comparison: inspect the named workflow, documented limitations and sources. No SDT output-quality benchmark or overall winner is claimed.

AI ASSISTANTS · DECISION DESK

Build a focused comparison.

Start with the same source pack and a clear deliverable. Compare how each assistant keeps context, revises the draft and hands the work back—not just how fluent the first answer sounds.

Scope: ChatGPT, Claude chat and Microsoft Copilot Chat/Pages. Compare the workflow around the answer, not unmeasured model intelligence.
Not this comparison: Not autonomous task-agent execution, coding agents or a source-recall benchmark.

Shared scenario: Turn a source pack into a revisable brief

YOUR COMPARISON

Compare the work. Not the hype.

How to read these assessments Documented workflows, not measured output-quality scores

Research-based workflow comparison, not a hands-on review. Each fact is scoped to a named product surface, plan or documented condition. Unknown does not mean unsupported. No numeric star score is assigned without a defensible same-task rubric and evidence; no cross-category winner or aggregate rating.

Documented workflowSource-backed capabilities and restrictions are facts, not quality stars.

Editorial workflow fitA score appears only with five row-specific anchors and evidence for the named task. Scores are not comparable across different scenarios.

Output qualityNo quality rating is assigned without appropriate comparable evidence. Missing evidence is not evidence of poor quality.

No aggregate score, overall winner or SDT hands-on test is claimed. Check the current product, plan and permissions before starting your own authorised trial.
