Quetext

The free tier of Quetext checks up to 500 words with its Deep Search plagiarism checker and scans up to 250 words with an AI content detector.

Quetext is a plagiarism checker and AI detector that also has paraphrasing and citation tools, so you can check a draft and fix the sources in a single place.

The free plan includes a website citation generator and a Citation Assistant.

Those word caps are small, so longer papers will push you toward a paid plan.

The Essential plan starts at $13.99 a month and covers 100,000 words, bulk uploads of up to 20 files, uploads from Google Drive and Microsoft OneDrive, and grammar and spell check.

It also includes AITutorMe.

The Enterprise plan starts at $11.99 a month and adds unlimited users, a Remarks tool and admin controls.

You pick the monthly word count that fits your volume, which suits schools and teams reviewing a lot of writing.
