A Turnitin Alternative Anyone Can Use
Turnitin is sold to institutions, so students and independent writers often cannot run their own checks. CheckAI lets anyone check text for AI writing — with sentence-level evidence and the option to rewrite flagged lines before submitting.
CheckAI is a self-serve Turnitin alternative for AI detection: anyone can check text for AI writing without an institutional account, see sentence-level evidence, and rewrite flagged lines before submitting. It is free to start with 20 checks daily. Note it focuses on AI detection, not plagiarism matching.
Self-check your writing in 3 steps
Paste your text
No institutional login, no waiting for a teacher to run a report. Paste your writing and check it yourself.
See sentence-level evidence
Get a line-by-line view of which sentences read as AI-written, instead of a single score with no explanation.
Revise before you submit
Rewrite flagged sentences inline and re-check, so you can fix issues before submission rather than after.
What an independent AI checker gives you
Self-serve access, real evidence, and a way to act on it.
No institutional account
Anyone can use CheckAI directly — students, freelancers, editors — without a school or company license.
Sentence-level evidence
See exactly which lines drive the AI score, so a flag is something you can examine rather than just a number.
Self-check before you submit
Run the check yourself, on your schedule, before the work is ever handed in.
Detect and rewrite together
Fix flagged sentences in the same editor and confirm the score drops — not just a report you cannot act on.
Why look for a Turnitin alternative?
Turnitin is a powerful tool, but it is sold to schools and universities, which means individual students and independent writers usually cannot run their own checks. You only see results if an institution runs them for you, often after submission, and typically as a single score. If you want to check your own work beforehand, you need something self-serve.
How CheckAI compares
CheckAI is not a plagiarism checker — its focus is AI-writing detection at the token level, available to anyone without an institutional account. Where Turnitin gives institutions a report, CheckAI gives the writer sentence-level evidence and the ability to revise flagged lines on the spot. The two solve different problems, so many people use CheckAI to self-check before any institutional review.
Check before you submit, not after
The most useful time to see an AI-detection result is before you hand work in, while you can still improve it. CheckAI is built for exactly that moment: detect, understand which sentences read as AI, rewrite them in your own voice, and submit with confidence.
