Who uses the A/B Test Significance Calculator?

t => `Editing your own drafts with objective feedback before a human editor sees them.`

Pro tips for the A/B Test Significance Calculator

t => `If readability scores run high (difficult), shorten sentences before you simplify vocabulary; structure moves the needle more.`
t => `Paste enough text for a meaningful read — a single sentence gives the ${t.name} little to measure; two or three paragraphs give it a voice.`
t => `Run your draft before your final version; the biggest metric improvements come from early structural edits, not last-minute polish.`
t => `Nothing you paste is uploaded anywhere, so use real drafts, not sanitized placeholders — the honest input gives the honest profile.`
t => `Track scores across revisions of the same document; the trend tells you whether editing is actually improving the piece.`

Five mistakes this tool prevents

t => `Assuming a good score means good writing — the metrics flag mechanical issues, meaning and voice are still yours to judge.`
t => `Editing without re-analyzing, so you never learn which changes actually moved the numbers.`
t => `Analyzing a rough outline and expecting final-quality insights — the ${t.name} profiles what is actually on the page.`
t => `Optimizing a single metric (word count) while ignoring the structure and key-term signals next to it.`
