GPTZero is a trusted tool to spot AI, but it’s not the only choice. Check out these ten other options.
When things are unclear, GPTZero is one of the few tools that can reliably stop AI misuse. But sometimes, we crave a fresh option. There’s always a chance for something better.
So, what other AI detectors can match or beat GPTZero? In this piece, we’ll share ten options and point out which are worth considering. Ready to dive in?
Winston AI
Winston AI is another favored tool. It’s a standalone platform designed to identify AI content across various models. In our test, it had a 59.2% average false positive rate, yet it achieved the highest true positive rate at 91.92%. However, that’s not the full picture. Winston AI was nearly perfect in our challenge that used text altered by Undetectable AI, scoring 11 out of 12, with all correct results at 100%.
This precision does come at a cost. They offer a free trial for 2,000 words, but beyond that, their least expensive plan, billed yearly, costs $12 monthly for 80,000 words. Their top-tier package is $19 monthly for 200,000 words.
Copyleaks
The tool that’s probably the simplest for AI detection today is Copyleaks. Copyleaks is a tool for analyzing AI and plagiarism, and it’s gaining popularity quickly. It uses advanced processing to figure out in seconds if a piece of text or code is from an existing source or created by AI.
How effective is it really? A study done independently shows it detects AI-generated content with over 99% accuracy. In our tests, it was 75% accurate for true positives and 80% for false positives. This makes it one of our top three recommended AI detectors, as it accurately identifies even human-written content.
Copyleaks offers a free version, but the full version ranges from $9.99 for 100 pages each month to $455.99 for 10,000 pages.
Sapling AI
Sapling is a tool that helps with writing and checking content using AI. Its main feature is spotting AI-generated text. Engineers from big places like Google, Meta, Stanford, and UC Berkeley made it, so it’s likely very reliable.
Great news: it really is. In our 2024 test, Sapling AI ranked second for true positive cases at 87.04% and topped the chart for false positive cases at 93.84%, outperforming even high-end AI detectors. Plus, it’s entirely free, and unlike other free AI detectors, it provides an AI likelihood score.
Originality AI
Originality AI was one of the first tools for AI detection and still ranks among the top options. It’s a reliable pick for those wanting to avoid dishonest content, scoring 70.29% on true and false positive tests in our 2024 review.
Originality AI offers two pricing options. You can get a monthly plan with 2000 credits for $14.95. Alternatively, you can choose pay-as-you-go, starting at $30 for 3000 credits. Each credit scans 100 words.
CrossPlag
CrossPlag is an AI detector worth noting, even though it wasn’t part of our 2024 accuracy tests. It’s unique because it can handle multiple languages. According to Undetectable AI, it’s among the most precise detectors available.
CrossPlag’s AI detector is free, but you need to create an account to use it.
QuillBot
Did you know QuillBot has an AI detector in their platform? This tool’s features keep expanding rapidly. While we can’t say for sure how well it stops AI misuse, a quick check with text from ChatGPT suggests it has potential in AI detection.
QuillBot offers a free AI detector, although it can only handle up to 1200 words at a time.
Scribbr
Similar to QuillBot, Scribbr, which is another well-known writing tool, includes its own AI detection feature. When I tested it with the same text used for QuillBot, it showed that Scribbr’s AI detection works well and responds quickly, which isn’t surprising.
Scribbr offers a free AI detector for up to 500 words. However, to access all its features, you need to subscribe to their premium plagiarism checker. The cost begins at $19.95 and can go up to $39.95 for large-scale processing.
ZeroGPT
If you’re mainly concerned about false positives, ZeroGPT could be a solid choice for your AI detection requirements. In our 2024 tests, it didn’t excel in true positives, yet it remains among our top five for minimizing false positives, making it worth noting as an alternative to GPTZero.
The free version is strong, handling up to 15,000 characters each time. For more features, pay $9.99 monthly, or choose $26.99 monthly for business needs.
Content at Scale
Content at Scale is a product we really like at Gold Penguin. It offers an excellent AI writing tool for blogs. Plus, its AI detection feature ranks among the best, placing in our top 5 for 2024 accuracy tests. It scored a weighted true and false positive rate of 67.64%.
You can check up to 2500 characters at a time using Content at Scale’s AI detector for free. This doesn’t include an AI likelihood score. If you require more, you have to subscribe to their premium plan, which costs $49 per month and includes their Generative AI suite.
SciSpace
I’ve recently come across SciSpace, and I find it quite impressive. It stands out from other AI detectors because it zeroes in on stopping AI misuse in academic settings. This helps teachers and students avoid the hassle of dealing with incorrect detections.
You can try SciSpace at no cost, but there’s a catch. Each session is limited to 1000 words.
The Bottom Line
It can be tough to find an alternative to GPTZero, a top AI detector. But if I had to pick the best from what I’ve talked about, I have three options in mind.
Copyleaks, Sapling, and Winston AI.
The main reasons are accuracy and experience. These tools have consistently shown they are very precise, even though AI detection can often be unreliable. I’ve used them more than any other AI detectors, so I can vouch for how well they prevent AI misuse and avoid false positives.
