Outputs

Claude Opus 4.7 7/10
Businesses today need to make the most of new technology to streamline how they work. The right tools can help companies boost efficiency and get more done than ever before.
Judge notes: "Get more done than ever before" leans slightly generic/cliché, and "the right tools" adds a mild qualifier not in the original, but the rewrite is otherwise clean and natural.
Claude Haiku 4.5 6/10
Businesses need to use modern technology to streamline how they work. The right tools can help companies operate more efficiently and get more done.
Judge notes: The rewrite is clean and readable but feels slightly flat and generic—it strips out too much energy, losing the persuasive tone intent of the original, and the two sentences feel disconnected rather than naturally flowing.
GPT-5.4 5/10
In today’s digital world, businesses need to use modern technology to improve how they work. These tools can help them reach new levels of efficiency and productivity.
Judge notes: The rewrite still keeps "In today's digital world" (the original cliché opening) and "levels of efficiency and productivity" (another AI staple), failing to truly humanize the text as instructed.
Gemini 2.5 Pro 6/10
To stay competitive, businesses need to use the latest technology to streamline their day-to-day operations. Adopting these innovative tools is how they can become more efficient and productive than ever before.
Judge notes: "innovative tools" echoes the original's AI-speak, "than ever before" is a cliché, and the rewrite still sounds slightly polished/generic rather than genuinely conversational.
Grok 4.1 Fast Reasoning 5/10
In our fast digital world, businesses need to use the latest tech to streamline their operations. That lets companies ramp up efficiency and productivity like never before.
Judge notes: The rewrite swaps one cliché phrase for another ("like never before" mirrors the original's "unprecedented"), retains "fast digital world" which still feels slightly AI-ish, and "ramp up efficiency and productivity" is generic corporate filler rather than a truly natural human phrasing.
