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 five dimensions. Weights reflect what matters most to a professional writer producing content commercially.
We submit identical prompts across every tool: a 1,500-word blog post, a cold email sequence, a product description, and a short story opening. Output is scored on coherence, originality, factual accuracy, and how much editing is required before it's publishable. A tool that produces clean copy in one pass scores higher than one requiring 20 minutes of cleanup.
Does the tool understand search intent? Can it structure content with proper heading hierarchy? Does it produce content that passes three AI detection tools we run on every output? Does it integrate keyword density naturally without keyword stuffing? Can it write meta descriptions and title tags that stay within character limits?
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, and onboarding. We deliberately bring in a tester who's new to each tool — not someone already familiar with it — to capture the real first-use experience.
Word count per dollar at every pricing tier. Whether the free plan is genuinely useful or a bait-and-switch. Hidden limits we discovered during testing (projects, seats, exports, API calls). Compared against the category average price. A $200/mo tool that produces $500/mo of value still scores well here.
Time to generate a 1,000-word article, measured 5× at different times of day across a 2-week period. Uptime during our test period. Quality consistency under load. API availability and rate limits for users who want to build workflows on top of the tool.
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 tested" 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 Signup to Published Score
No free accounts from vendors, no early access arrangements, no sponsored placements. We sign up and pay like any regular customer — on the public pricing page, with a credit card. Every tool on this site cost us real money.
Not a weekend experiment. We use each tool on real work — blog posts, email sequences, product copy, client briefs — across several weeks. The score reflects the experience of a professional writer who relies on this tool daily, not someone doing a demo.
Every tool gets the exact same 12 test 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 by three different writers with different use cases — a blogger, a copywriter, and a content strategist. Final scores are averaged. No single reviewer's preferences dominate the result.
AI tools update constantly. A score from 6 months ago is often worthless today. We re-run the full test battery quarterly and update scores when a meaningful change is detected. The 'last tested' 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. 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.

The Tester
I ran a 20-person content agency before GPT-4 changed the industry. I shut down half the team and started testing every AI writing tool obsessively. Every score on this site comes from real work — not toy prompts, not sponsored placements.
