Overall score
9.1
Claude Pro
long-form writing
The best editor of the group. Give it a 6,000-word document and a style guide and it holds both in mind to the end, which nothing else tested does as consistently.
Pros and cons
Claude Pro
What works
Holds tone and structure across very long documents
Least likely to invent a citation when asked not to
Excellent at critique — it will tell you a draft is weak
Large context window handles a whole content library at once
What doesn't
Image generation is absent; you will need a second subscription
Slower on short prompts than the alternatives
Occasionally over-hedges on straightforward factual questions

Synthesia questions
Can I use it for customer-facing ads?
Not yet, in our view. Internal training and onboarding is where it earns its score.

A three-minute video rendered in under six minutes across every test run.
