Your independent guide to AI detectors — how AI detection works, how accurate the best AI detectors really are, and honest reviews of every major AI content detector, for writers, students, educators, and professionals in 2026.
Browse ArticlesEverything about AI detection — for everyone whose writing gets checked by a machine.
AI detectors claim to tell human writing from machine writing. Here's how they actually work under the hood, what their scores really mean, and where they break down.
The four articles that explain the whole field — read these and every detector score you see will make sense.
The pillar guide: what detectors measure and what scores mean.
2Perplexity, burstiness, and watermarks in plain English.
3Why human writing gets flagged and what to do about it.
4The practical pre-submission workflow, step by step.
RepDex is an independent publication built on one simple rule: We only publish claims about AI detection we've actually verified.
We run real text through real detectors before we write about them — so accuracy claims you read here come from testing, not from marketing pages.
We take zero sponsored placements from detector vendors. Our coverage says what actually works and what doesn't, never what pays us.
False positives cost students grades and writers clients. We cover AI detection with the seriousness those stakes deserve, wherever you are in the world.
A hands-on review of GPT CleanUp Tools — the free browser-based AI text cleaner I run on every draft to strip invisible characters and em dashes before publishing.
TruthScan sells one suite to detect AI text, images, and voice. We separate the three claims, weigh the honest reality per modality, and ask whether one product can credibly cover three arms races at once.
Sightengine is a developer-first content-moderation API that folds AI-generated-image detection into a broad classification suite. We look at what it actually is, how the AI signal fits a moderation pipeline, how it compares to Hive, its usage-based pricing model, and who should (and shouldn't) integrate it.
SciSpace (formerly Typeset) is a research assistant grad students rely on for literature review and drafting — and it bundles an AI detector. But formal academic prose is the exact input most likely to be falsely flagged. An honest look at who it suits, and why it is not the screening tool that decides your submission.
Proofademic bundles AI detection into an academic writing assistant aimed at students and non-native writers. An honest look at what its detector can tell you, why its own users face the sharpest false-positive risk, and why a clean result here doesn't mean a clean Turnitin result.
NoteGPT is a study toolkit first and an AI detector second. Here is an honest look at its bundled checker, what its consumer-grade limits mean, and whether it is actually a good AI detector.
RepDex is an independent publication focused on AI detection. We explain how AI detectors work, test how accurate they really are, and publish practical guides for anyone whose writing gets checked by a machine — students, writers, editors, and educators. Everything we publish is verified by our editorial team, with no sponsored content and no affiliate bias.
