What is an AI testing tool?
An AI testing tool is software that uses artificial intelligence to test, evaluate, and improve websites and apps. It is different from an automation tool because where automation conducts repetitive tasks to save humans time, AI takes it a step further by learning from those tasks, making decisions based on inputs, and improving over time. Therefore, while all AI testing tools use automation, not all automation tools use AI.
AI testing tools can greatly enhance your QA testing. According to 探花精选 research conducted in May 2023, 90% of web developers said they used an AI tool to help with web development or related tasks in the past three months. Of those, 63% used it for testing or identifying errors in coding—the number one AI use case reported.
Why use AI website testing tools?
In the past year, there’s been a boom in AI 迟辞辞濒蝉—蹿谤辞尘 s to . Let’s look at how AI enhances QA specifically.
It’s faster.
The biggest draw of AI tools is that that they take time-consuming, tedious tasks and automate them, saving you time. For example, AI website testing tools can test a website on thousands of devices and browsers in seconds. That just wouldn’t be possible with manual testing.

It reduces the need for human intervention.
Especially with features like , AI testing tools can not only generate tests but also update test scripts after UI changes, freeing humans to do more complex problem-solving on the website or app.
It can be more accurate.
Having a human manually review UI revisions, for example, is a very energy-draining process. Tired eyes might miss a visual error, especially if it’s small. Edge cases get overlooked. Many developers who spoke to me for this article mentioned instances where human testing missed errors that AI caught.
AI Testing Tools: Features to Look for
Access to Real Devices
are great for testing at scale, but using real devices for testing is still the gold standard. Many AI testing tools offer one or both, so be sure to check.
No-Code/Low-Code Features
In QA, sometimes non-developers are conducting testing. If that’s the case for you, look for no-code or low-code features.
For example, some AI website testing tools use natural language processing (NLP) so that you can converse with it in plain English, and the AI will generate the tests or code for you.
Some AI testing tools also have recorders, where you can record a user flow on your website, and it’ll generate test cases based on that.
Number of Browsers/Devices/OS That It Tests On
The more browsers, devices, and OS you can test your website on, the better. This ensures your website will look and work the way you intend, no matter how the end-user is accessing it.
Self-Healing
Perhaps the most incredible part of AI is that it can actually take the data and make decisions based on it. That means that some AI website testing tools can “.” In other words, not only will it identify the issue, but it will also fix it for you, too.
Integrations
Many QA teams use a suite of tools to conduct their reviews and testing. So, if there’s a tool you already use and love, and you just want to use AI testing tools to enhance it, be sure the AI tool plays well with your tech stack.
For instance, many of the AI testing tools in this article integrate with the popular open-source automation tool .

- Advanced match levels mean Applitools can distinguish between critical errors and acceptable ones
- Accessibility testing to ensure WCAG compliance
Free Trial? Yes, 14 days
However, a heads up: When I signed up for the free trial, I got a screen saying that the Applitools team was reviewing my request (something I’ve never had happen with any other free trial).
What Developers Say
, CEO,
“I first discovered Applitools when working on a complex ecommerce site redesign for a client. The site had hundreds of product pages, and manually checking each one for visual bugs after updates was becoming a nightmare.
“Applitools uses AI-powered visual testing to automatically detect UI issues across different browsers and devices. I set it up to take screenshots of key pages before and after each code push, then compare them pixel-by-pixel.
“On one occasion, it flagged a subtle layout shift on mobile product pages that I had completely missed. A CSS change had caused product images to overlap with the ‘Add to Cart’ button on certain phone models. Without Applitools, this could have led to frustrated users and lost sales.
“What I love most is how it integrates seamlessly into our CI/CD pipeline. Now, every time we push code, Applitools runs in the background and alerts us to any visual regressions. This has cut our QA time by at least 30% and caught numerous issues before they hit production.”

Top Features
- Free to use! Except for the OpenAI models. For those, you do need to get your own OpenAI API keys.
- Generates test ideas
- Generates automation scripts
- Provides accessibility testing
Free Trial? TestCraft is free to use.
However, you need to get your own OpenAI API keys.
What Developers Say
, VP of Global Operations & Marketing,
“TestCraft‘s accessibility testing features changed how we approach inclusive design. Instead of treating accessibility as a final checklist item, we now use TestCraft’s suggestions during initial development. The AI analyzes elements in real time, helping us catch accessibility issues before they become embedded in the codebase.
“When building a client‘s navigation menu, TestCraft flagged that our color contrast ratios would cause readability issues for visually impaired users. It didn’t just identify the problem — it suggested specific color combinations that would meet WCAG standards while maintaining our design aesthetic. This proactive approach prevented a major redesign later.
“Development cycles shortened because we stopped retrofitting accessibility features post-development. The AI helps us build inclusively from the start, reducing the need for major revisions during final testing phases.”
AI Testing Tools FAQs
Will testers be replaced by AI?
Oh, this is a hot topic for debate. Many QA professionals and others fear that AI will take their jobs. However, from my research, it looks like most QA teams are using AI tools to enhance their QA process — not replace human testers entirely.
Let’s give you some hard numbers to prove that point, though: In the , only 2% of respondents reported that automation had replaced all of their manual testing — down one percent from 2023.
Can AI do automation testing?
Yes, that’s what AI testing tools are for! They take tedious, time-consuming tasks and automate them, freeing up developers to spend their brain power on more complex tasks. Beyond that, though, AI can learn from the data it receives and make suggestions or apply fixes.
Will AI take over QA?
As anyone who’s ever used ChatGPT knows, AI can still make mistakes. Therefore, even when using AI in QA, a human still needs to oversee and review it all. For that reason, I don’t think AI will completely take over QA.
Can AI write test cases?
Yes! Pretty much every AI testing tool I included in this article can write test cases. In fact, often that’s what the developers who spoke with me loved about incorporating AI into QA.
How will you use AI testing tools to enhance QA?
Before writing this article, I had no clue the depth and breadth of AI testing tools in the QA process. You hear a lot of chatter of AI’s ability to write code, but I think it’s incredible how it can test and fix code, too.
Many developers hate the tedium of writing test cases, and now, AI can do that. It can catch visual regressions overlooked by the human eye. It can even “self-heal” test scripts after a code push.
I encourage you to explore how these recommended AI testing tools could enhance your QA workflows. And if you’re looking for a CMS with AI tools and A/B testing embedded to ensure you build and maintain the best website possible, check out .
