Detection Score
Higher means a stronger AI writing signal. This is an estimate, not proof of authorship.
Readability
Rates how easy the text is to read on a scale from 0 to 100 — higher scores mean easier reading.
Grade Level
Indicates the U.S. school grade level needed to understand the text — higher education levels mean more complex reading.
A practical workflow
Make the most of your free checks
- 01
Choose the right passage
Use connected paragraphs you want to review. Remove unrelated headers and check the word count before scanning.
- 02
Read the result in context
A score is an estimate, not a certificate of authorship. Check the draft’s sources and the writer’s process before taking action.
- 03
Use more capacity when needed
If you regularly review longer or more numerous documents, compare the paid tiers. They increase capacity; they do not guarantee an authorship verdict.
What is included for free?
Free detection includes a passage-level score plus readability and grade-level estimates. Free use supports text entry; document upload requires a paid plan. Free use is limited to 5 scans per day and 750 words per scan. Humanization is a separate paid feature, so the free detection allowance is not a free humanizer subscription.
When does a paid plan make sense?
Choose a plan based on the number and length of passages you actually check. Paid tiers range from 100 to 500 detection scans per day, with 750 to 1,500 words per scan. Eligible first weekly or monthly subscriptions have a $1 introductory 3-day period, then renew automatically at the selected regular price. Annual plans are excluded.
