What is an AI Score Checker?
An AI score checker analyses text and estimates how much of it reads as machine-generated. Realword reports the score sentence by sentence rather than as a single document-wide percentage, so you can see which lines are the problem instead of guessing.
Start freeFour steps. No setup.
Paste your text
Any draft, up to 50,000 characters. Written by you, by AI, or a mix of both.
Get a score
Realword returns an overall reading plus a sentence-by-sentence breakdown of what looks machine-written.
See the flagged lines
Each sentence is marked, so you know where the problem is, not just that one exists somewhere.
Fix in one click
Send your text to the AI Humanizer, then run the check again to see the new score.
Everything in one place.
A number you can act on, not just worry about.
A single "62% AI" verdict tells you nothing about what to fix. Realword marks each sentence on its own, so you can see which lines are driving the score and judge whether the flag is fair.
- Per-sentence marking, not one document score
- Each sentence shows its own AI score
- Catch false positives on your own writing
Checking and fixing in the same place.
One click moves your text into the humanizer, and the Score Checker is one click away to confirm the result. You see the problem lines first, so you know how much rewriting the draft needs.
- Your text moves into the humanizer in one click
- Choose style, type and language before rewriting
- Re-check afterwards to confirm the fix
A brand people recognise is a brand people come back to.
Check before anyone else does.
Run the check while the draft is still yours to change, not after a client or editor runs their own. Every check is saved to your history.
- Past checks saved to your account
- Open any earlier result from your history
- Send a draft to the humanizer and check it again
Catch flat lines before they go live.
Some clients and editors run their own detector on what you send. Running a check yourself first lets you fix the lines that read as AI while the draft is still yours.
- Catch problems while the draft is still yours
- Check your own writing for false positives
- Make it a standard step before delivery
