Mydetector

The core function takes pasted text or a file and returns a single AI detection score, roughly the odds that the passage is machine-generated. It pairs the number with sentence highlights, so you see which lines dragged the score up instead of guessing. That sentence-level view is the difference between a vague flag and something you can act on. Big difference.

Past the headline score, the AI checker breaks down how the text reads. Sentence analysis looks at structure and rhythm, while vocabulary insights flag flat or repetitive word choices that show up in AI generated text. For writers, that feedback doubles as an editing checklist.

You don't have to copy-paste long reports. The free AI detector reads PDF, Word, and PowerPoint files, then highlights AI generated text inside them. Results land in the same view, so a 40-page report costs no more clicks than a paragraph.

Flagged text can be run through a humanizer, which rewrites passages to sound more natural. The Basic model handles 1,000 characters per quota; the Pro model trades that for quality at 200 characters per quota. It's a convenience feature, not a guarantee, and it draws from the same quota pool as detection, so heavy humanizing burns through your monthly allowance faster than plain checking does.

Mydetector bundles more than text detection. An AI image detector runs at 10 quotas per image, a code detector scans 500 characters per quota, and there's a grammar checker plus a plagiarism checker at the same rate. Handy if you'd rather stay in one tool than juggle four.

Usage runs on quotas rather than flat unlimited access. The free tier gives 20 quotas a month after signup, and paid plans start at $6.99/mo for 1,100 quotas, scaling to an unlimited tier. It's a fair fit for occasional checks and a real cost for anyone running constant scans. Pick based on volume.
