Stella.ai Review – Can You Really Earn $25/Hour Training AI?

Stella.ai is a fairly new AI-based platform that offers remote work opportunities for subject matter experts. On the surface, it looks like a promising way to earn up to $25 per hour by contributing to the development of AI systems.

But is Stella.ai legit or just another platform with bold promises and little to back them up?

In this review, I’ll walk you through my personal experience testing the platform, including what the sign-up process looks like, what kind of work you can expect, and whether or not it’s worth your time.

What is Stella.ai, and what does it offer?

Stella.ai is an AI training platform that claims to hire individuals from diverse backgrounds to help improve artificial intelligence. This involves completing various tasks like ranking chatbot responses, conducting research, and answering academic or technical questions.

The platform markets itself as a way to earn flexible income—$25 per hour—working remotely. Jobs are available across a wide range of subjects, including:

• Mathematics

• Creative Arts

• Programming Languages

• Sciences and Humanities

• Law and Business

To qualify, Stella.ai typically expects applicants to have at least a university degree or be highly knowledgeable in a particular field. They’re not just looking for general users—they want experts who can provide accurate and reliable information to train their AI systems.

How does the application process work?

To get started, you need to register with an email and password and verify your email. From there, you’ll be taken to a dashboard where you begin a Skill Assessment Test—this is a crucial step that determines whether or not you’ll be accepted.

The skill test can take anywhere from 45 to 90 minutes and will include:

• Choosing the best AI-generated response to a prompt

• Demonstrating how to conduct credible research

• Creating short-form content or stories

• Answering subject-specific questions accurately

Some of the questions can be tricky, especially if you're unfamiliar with the topic. The platform encourages the use of Google but discourages the use of AI tools like ChatGPT, emphasizing the need for authentic human input.

While using AI tools for inspiration isn’t entirely forbidden, copying directly from them may reduce your chances of passing the assessment.

How do you get paid on Stella.ai?

Stella pays via PayPal, so having a verified and functional PayPal account is required before you can complete your profile. Once you’ve passed the skill test and completed your application by filling in your education, location, subject of expertise, and availability, you're eligible to be matched with tasks.

These tasks are paid on an hourly basis, and you’ll be notified when tasks are available that match your skill set.

How much can you earn?

Stella claims that workers can earn $25/hour, which is fairly competitive compared to many other remote platforms. However, availability of work isn’t guaranteed, and you’ll need to perform well in your assessment and be an expert in your field to qualify.

Since I haven’t been accepted yet, I can’t confirm how consistent the work is—but based on what’s shown on the website, the earning potential could be solid for those who make it through the vetting process.

Can you use Stella on mobile?

While the platform doesn’t appear to have a dedicated mobile app, the website seems responsive enough to work on mobile browsers. That said, due to the complexity of the tasks, I strongly recommend using a laptop or desktop for both the application process and actual work, especially since many tasks require deep research or long-form writing.

Who can join Stella.ai?

Stella.ai appears to be available globally, and they emphasize diversity in their hiring practices. However, your ability to join depends on:

• Your academic background or subject-matter expertise

• Ability to pass the skill assessment

• Having access to PayPal for payment

• A decent level of English proficiency

There’s no clear list of eligible countries, but I was able to register from my location without any issue.

Can you get support or find reviews?

Here’s where things get a little uncertain.

At the time of testing, I wasn’t able to find many user reviews or testimonials from independent sources about Stella.ai. The platform seems new, and it’s hard to verify its track record. While the website looks professional and the concept is promising, the lack of third-party feedback makes it difficult to determine how reliable it truly is.

Their support options also seem limited. If you run into issues, it’s unclear whether there’s a responsive support team available.

Final Verdict: Is Stella.ai worth it?

Stella.ai looks like a potentially legitimate opportunity to earn decent income while contributing to the development of AI. However, it comes with a few caveats:

Pros:

• High potential pay ($25/hour)

• Flexible and remote work opportunities

• Wide range of subject areas to choose from

• Professional-looking platform

Cons:

• Skill test is long and may be difficult

• Little to no user reviews online

• Requires academic expertise to qualify

• Limited support options

• PayPal is the only payment option

If you’re an expert in a field and enjoy research or training AI systems, Stella.ai could be a good opportunity to explore. But I’d recommend proceeding with caution and doing your own due diligence first.

And as I always say—don’t rely on just one site. Apply to multiple platforms to increase your chances of getting accepted and finding steady work.
