AI Detect
XYZAI, Inc. · AI Detection
AI Detect is a web-based AI detector and humanizer that checks whether a block of text was written by a person or a language model. You paste in an essay, article, or draft, and it returns an AI detection score plus readability and grade-level ratings within seconds. It's aimed at students, teachers, editors, and hiring teams who need to verify writing before they submit or publish it. The free tier allows 5 scans per day, and paid plans lift the word limit and daily scan count.
About AI Detect
What Is AI Detect
AI Detect is an online tool for spotting AI-generated writing. It runs text through detection models and gives you a score that shows how much of the content reads as machine-made, along with two side scores for readability and U.S. grade level. The company behind it, XYZAI, Inc., positions it for high-stakes checks: academic review, editorial workflows, recruiting screens, and brand publishing.
The appeal is speed and simplicity. No install. No desktop app. No API keys to manage for casual use. You open the site, paste text, and get a result. That makes it easy to reach for before you send a paper off to a professor or push a draft live.
The catch is the free plan's limits. At 5 scans a day and no humanizer access, heavy users hit the ceiling fast. The humanizer, which rewrites flagged text, sits behind the paid tiers. So you can't test that part without paying. There's also no mobile app or public API right now. It stays a browser tool.
Getting Started
- Go to aidetect.com and open the AI detector page.
- Paste the text you want to check, or type it into the input box.
- Run the scan and read the AI detection score along with the readability and grade-level ratings.
- If the text gets flagged, either revise it yourself or upgrade to a paid plan to use the humanizer.
- Sign in if you want your scan history and higher daily limits tied to an account.

Key features
AI Detection Scoring
The core feature takes pasted text and returns a score for how likely it's AI-generated. AI Detect says it uses detection models built to catch output from tools like ChatGPT. That means you get a judgment, not just a similarity match. Results come back fast. That matters when you're checking several pieces in a row.
Built-In Humanizer
Paid plans include a humanizer that rewrites flagged text to read more naturally. This is what separates AI Detect from a plain AI detection tool, and the company claims the rewritten output bypasses other detectors. You can't use it on the free tier, so it stays a paid-only workflow.
Readability and Grade Level
Alongside the AI score, the tool rates how easy the text is to read on a 0 to 100 scale and estimates the U.S. school grade level needed to understand it. For teachers, that's a quick way to see if a piece matches the level it's meant for.
Daily Scan Limits by Plan
Each paid tier sets its own ceiling: 100 scans a day on Detection Beginner, 150 on Pro, and 500 on Ultimate, with per-scan word limits of 750, 1,000, and 1,500 words. The free tier gives you 5 scans a day. Higher plans also raise how many humanizations you get daily, which matters most if you plan to run the rewrite step on every flagged draft.
Weekly, Monthly, and Yearly Billing
You can pay weekly, monthly, or yearly, and the plans are priced per day in the weekly view, starting around $0.57 a day. That suits people who need the tool for a short stretch, like exam season, rather than a year-long commitment. If you only have a handful of documents to check, the free plan already does the job.
Pros and cons
Pros
- Free tier works without a credit card, so you can test detection before paying.
- Combines detection, readability, and grade-level scoring in one screen.
- The humanizer gives you a way to fix flagged text without a separate tool.
- Short-term weekly billing fits one-off projects and exam periods.
- Results come back quickly, which helps when checking many samples.
Cons
- The free plan's 5 daily scans run out fast if you're checking more than a couple of documents.
- The humanizer is locked behind paid plans, so you can't evaluate the full workflow for free.
- Web only, with no mobile app, so you can't scan text offline or on the go.
- No public API, which rules it out if you want to plug detection into your own system.
