Free AI detector that scores text, images and code for machine authorship
Beginner
What is MyDetector?
MyDetector is a free, browser based AI detector that scores pasted text or uploaded documents for machine authorship, marks flagged sentences and adds vocabulary insights. It bundles image and code detection, a humanizer, and grammar and plagiarism checks, and supports nine plus languages including English, Chinese, Spanish and German.
MyDetector is a web based AI detection service that estimates whether a piece of writing came from a language model or a person. Its core detector accepts pasted text or uploaded files (TXT, DOCX, PDF and PPT) and returns an AI score on a 0 to 100 percent scale, along with sentence level highlights and a short vocabulary breakdown. The stated method is pattern based: models are trained on mixed human and machine corpora, then look for uniform sentence rhythm, flat vocabulary and repeated phrasing, traits that tend to cluster in generated prose. The product is organised as a small suite rather than a single checker. Alongside the content detector there is an image detector, a code detector, a humanizer for rewriting flagged passages, plus grammar and plagiarism checkers. Two detection models are offered, one tuned for speed and one that digs deeper, and users can switch between them depending on whether they want a quick read or a more detailed report. Uploaded documents are scanned in the same view, which matters for anyone reviewing long reports or assignments instead of short paragraphs. Typical users listed by the site include content creators and marketers checking drafts before publishing, educators reviewing essays, legal teams scanning summaries and clauses, data scientists filtering generated dataset entries, and ordinary people vetting suspicious messages or reviews. The workflow is deliberately simple: paste or upload, run the scan, read the score, edit the flagged sentences and rescan. Where it sits among alternatives: MyDetector competes with other free detectors on cost of entry rather than on any published accuracy benchmark, and it is honest about the limits of the category, stating that no detector is fully exact and that a score is a signal rather than proof. That framing makes it a reasonable first check for mixed human and AI drafts, but not an adjudication tool for academic misconduct or legal disputes on its own.
How do you use MyDetector?
1Open the free detector and pick your input method
Go to the homepage and either type or paste text into the box or use the upload option for TXT, DOCX, PDF or PPT files. The character counter shows the current limit on a single submission.
2Run the scan and read the AI score
Submit the content to receive a 0 to 100 percent AI score plus a breakdown. Compare the AI and human portions side by side to see how much of the passage reads as machine written.3Inspect the flagged sentences
Each sentence judged likely to be AI generated is highlighted and scored individually. Review those lines first rather than rereading the whole document.4Rewrite with the humanizer or edit manually
Send flagged text to the AI humanizer for a more natural tone, or revise it by hand to vary sentence rhythm and vocabulary, then scan it again to confirm the change.
5Extend checks to images, code or originality
Use the separate detectors if you also need image or source code screening, and run the plagiarism and grammar checkers on the same draft for a fuller review before publishing.
6Compare plans once trial credits run out

Pros and cons
Pros
- Free tier with trial credits and free credits on sign up, so real documents can be tested before payingAI

- Multi language coverage across English, Chinese, Japanese, Spanish, Portuguese, French, Russian and GermanAI
Cons
- No published accuracy benchmarks, and the site itself admits detectors can misflag structured human writingAI
