How We Review AI Writing Tools
Every score on getwritestack.com comes from the same process. Here is exactly how we test, weigh, and update our reviews.
The four things we score
We rate each tool out of 5 on four criteria, then combine them into an overall score. Output quality carries the most weight, because it is what actually saves you time.
Output quality
How good the writing is before heavy editing: coherence, accuracy, and how well it follows instructions. We weigh this most, because a cheap tool that produces unusable text saves nobody time.
Ease of use
How quickly a new user gets a usable result. We look at the interface, templates, onboarding, and how much prompt-wrangling each tool needs.
Value for money
What you get per dollar, including free tiers and entry plans. A higher price is fine if the output and features justify it; we flag tools that do not.
Features
Depth and breadth: long-form support, SEO and research tools, brand voice, integrations, collaboration, and anything that fits real workflows.
How we test
We use each tool on the kind of work it is built for: long-form drafts for content platforms, short-form copy for marketing tools, paraphrasing for rewriting tools, and so on. We compare output on the same briefs, note how much editing each result needs, and account for who the tool is actually for. A fiction tool is not penalized for being weak at ad copy, and a budget tool is judged against its price.
Keeping reviews current
AI tools change fast: pricing shifts, features ship, and plans get repackaged. Each review shows a last-updated date, and we revisit pricing and features regularly. Because plans change between updates, we show pricing as a starting point and always link to the official site for the current numbers. If you spot something out of date, tell us at info@getwritestack.com.
Independence
We earn affiliate commissions, but they do not affect scores or rankings. We score the highest-paying and lowest-paying tools by the same rules. See our affiliate disclosure for the details.
