How We Test & Score
AI Writing Tools
Every score on this site is the result of a documented, repeatable process. We publish our methodology in full because we think you deserve to know exactly how we arrived at every number — and to judge whether our approach makes sense.
5-Dimension Scoring
The overall score is a weighted average of four dimensions. Weights reflect what matters most to a professional writer producing content commercially.
The most important dimension — by a margin. We evaluate identical briefs across every tool: a 1,500-word SEO article, a cold email sequence, a product description, and a creative passage. Output is scored on coherence, originality, factual accuracy, tone appropriateness, and how much editing is required before it's publishable. A tool that produces clean, publish-ready copy in one pass scores higher than one requiring extensive rewriting.
Breadth and quality of the toolset beyond raw generation: templates, brand voice controls, multi-step workflows, team collaboration features, integrations (Docs, Notion, Zapier, API), and the quality of specialized modes. A bare-bones generator scores lower than a platform with a full workflow suite — even if raw output quality is similar.
Time from signup to first usable output. Learning curve for a professional writer who has never used the tool before. Quality of templates, guided workflows, onboarding sequences, and error recovery. We assess the real first-use experience — not the polished path shown in vendor demos.
Time to generate a 1,000-word article. API latency for programmatic users. Export and delivery speed. We look for consistency as much as raw speed — a tool that's fast at first but slows down under load gets penalized.
How to Interpret the Numbers
Use this. It's the best available for its category. Minor limitations exist but don't outweigh the value.
Solid choice with real limitations. Often the right pick for specific use cases or tighter budgets.
Not worth your time or money at current pricing. We still document why, so you can judge for yourself.
Scores are not permanent. A tool that scores 65 today can score 82 in 6 months after a major update. That's why every score shows a "last updated" date. Use it.
The 12 Prompts We Use on Every Tool
Every tool gets the exact same 12 prompts — no variation, no advantage. This is what makes our scores comparable rather than impressionistic.

From Research to Published Score
We research each tool through its documentation, pricing, features, and real user feedback, using trials where possible. No sponsored placements, no pay-to-play. Every review starts from independent research.
Not a demo. We evaluate each tool against real content goals — blog posts, email sequences, product copy, and more. The score reflects the experience of a professional writer, not the polished path shown in a vendor video.
Every tool is evaluated against the exact same 12 prompts — same word counts, same topics, same constraints. 4 long-form, 4 short-form, 2 SEO-specific, 2 creative. This makes scores directly comparable across tools, not impressionistic.
Each tool is scored on the same rubric across all four dimensions, so the result reflects the methodology rather than any single reviewer's preferences.
AI tools update constantly. A score from months ago may not reflect the current product. We revisit reviews and update scores when a meaningful change is detected. The 'last updated' date is shown on every review.
Some links on this site are affiliate links — we earn a small commission if you sign up. This does not affect our scores, which are set before any affiliate links are added. We've given some of our lowest scores to tools with the best commission rates. Our independence is the product — without it, this site has no value.
