Stellar AI Is Closing: What It Paid, and Whether It Was Legit

Stellar AI Is Closing: What It Paid, and Whether It Was Legit - Remote work article featured image

Most AI training platforms make you pass an unpaid test before you earn a cent. Stellar AI is widely said to do the opposite, paying you to take the qualification itself. That claim is the reason most people click on this platform, so this review starts by checking whether it actually holds, then covers what Stellar really pays (considerably more than most articles about it suggest), and the one risk nobody mentions.

Update, October 2026: Stellar AI is closing. Its homepage now reads "We are winding down annotation efforts at Stellar AI." There is no new work to apply for. If you already have an account, you can still log in to check your balance and request payment for any remaining funds, so do that now. The review below is kept as a record of how Stellar worked and what it paid.

The quick answer: Stellar AI (joinstellar.ai) was a legitimate platform, and it is now closing. It published Terms of Service, a real tiered rate card running from $25/hr for generalists up to $200/hr for machine learning engineers, and paid weekly via PayPal. The widely repeated claim that it paid you to take the qualification test is supported by a first-hand contributor account ($40), though Stellar itself never documented it. The real catch was not pay, it was access: Stellar said plainly that there was no set timeframe between joining its annotator pool and getting a first project, and some people never got called.

Pay figures come from Stellar AI's own published role listings. Where a figure comes from a contributor report rather than Stellar itself, it is labelled as such, with the age of the report given, because this platform moves quickly and an old number is not a promise.

What is Stellar AI?

Stellar AI, at joinstellar.ai, is a flexible, project-based platform connecting contributors with data annotation and AI training work. In its own words the arrangement is open-ended contract work, not employment: no fixed schedule, no set end date, task-based, and you operate as self-employed. The task range is broad, from rating AI chatbot answers, fixing summaries, fact-checking and small research assignments, through to writing challenging prompts for AI agents, converting GitHub pull requests into agent tasks, and building prompts with correct answers and evaluation rubrics attached.

The stated requirements are modest: you must be 18 or older, have a reliable internet connection, strong attention to detail, fluency in English, and a PayPal account so they can pay you. No prior experience is required for most projects, and Stellar provides training materials plus a contributor forum. The first-hand account cited later in this review is from a business student whose own summary of their technical background was that it stopped at spreadsheet formulas, so the generalist track really is open to non-technical applicants.

Is Stellar AI legit?

Yes, and the evidence here is cleaner than on several platforms we have reviewed recently. Stellar publishes real Terms of Service and a public roles page with explicit pay bands, which vague operations do not tend to do. Independent reviews from unrelated sources converge on the same basic picture, real tasks and real weekly payment, and no fraud allegations surfaced in research. There is no fee to join.

Two honest gaps. Country eligibility is not published anywhere, so if you are outside the platform's usual markets the only way to find out is to apply. And no company leadership or corporate history is published on the site, which is a transparency gap rather than a red flag, but worth knowing.

How much does Stellar AI actually pay?

This is where most articles about Stellar AI get it wrong, and badly. You will see the range quoted as "$25 to $40 an hour" in several places. That is a misreading: $40 is the reported payment for taking a qualification, not an hourly rate. Stellar's actual published rates go far higher, and it lists them openly on its own roles page.

Stellar AI Discover Available Positions page listing five roles with published hourly rates: Senior Software Engineer 70 to 160 dollars per hour, Machine Learning Engineer 80 to 200 dollars per hour, Junior Software Engineer 35 to 100 dollars per hour, Technical Recruiter with no rate listed, and Generalist at 25 dollars per hour plus, with Guaranteed Hours Contract badges on the three engineering roles
Stellar AI's own open-roles page. Note the Guaranteed Hours Contract badges, which appear on the three engineering roles but not on Generalist.
Role Published rate Guaranteed hours?
Machine Learning Engineer $80 to $200/hr Available
Senior Software Engineer $70 to $160/hr Available
Junior Software Engineer $35 to $100/hr Available
Generalist $25/hr and up Not advertised

The individual role pages narrow those bands to what you get after qualifying: around $70 to $100 an hour for senior software engineering, $80 to $120 for machine learning, and $35 to $70 for junior software engineering. Stellar's FAQ confirms the floor directly: "Our base rate is $25 an hour, although earnings vary based on the type of project, your efficiency, and the number of hours you choose to work." Payment is weekly via PayPal.

There is also progression inside the generalist track. The contributor account below describes moving into a reviewer role and earning above the $25 base, so the entry rate is a floor rather than a ceiling even if you never touch the engineering tiers.

Does Stellar AI really pay you to take the test?

This is the platform's most repeated selling point, so it deserves a straight answer: probably yes, but Stellar does not say so itself.

Nowhere on joinstellar.ai is a paid assessment mentioned. The four-step joining process lists only "completing a skill-match test", the FAQ says nothing about paying for it, and the Generalist role page advertises no qualification payment at all. What does exist officially is on the senior technical tracks: the Senior Software Engineer listing states a $600 qualification bonus, paid upon passing. That is a different thing from being paid to attempt a test, and it applies to one high-tier role, not the generalist path most readers will take.

What a contributor reported. A widely upvoted first-hand account on Reddit's r/WFHJobs describes it plainly:

"Unlike other platforms, Stellar AI actually pays you ($40) to take a qualification for a project. Since passing this qualification I have had consistent work at $25 an hour... the company pays every Tuesday on the dot and I have never had any problems here."

Worth weighing properly: this is one contributor's experience, posted roughly 20 months ago, and the writer says themselves that it may not be everyone's. Treat the $40 as a reported figure from that period, not a current guarantee. Ask what the qualification pays before you sit it.

How to join

Four steps, per Stellar's own description:

  1. Share your background. Your interests, education and skills.
  2. Complete a skill-match test. This is what determines which projects you are matched to.
  3. Review and sign contractor agreements. You are contracting as self-employed, not being hired.
  4. Set up payment. PayPal details, for weekly payment.

The real catch: you join a pool, not a job

This is the part worth reading twice, and it is more specific than the usual "work can be inconsistent" warning. Stellar is candid about it in its own FAQ: work is project-based and depends on client demand, so skill-match tests are reviewed and contributors onboarded from the pool on a rolling basis, only when a matching project appears. In their words, "There's no estimated or set timeframe between joining the annotator pool and being onboarded to your first project," and they explicitly cannot give updates or estimates in advance.

Read plainly, that means passing the test is not the same as getting work. You can qualify and wait indefinitely. Against that, the contributor account above reports being accepted within about two days and having consistent work since, so it clearly moves quickly for some people. Both things are true, and which one you get depends on whether your skills happen to match a live project.

The three engineering roles are the exception worth noting: each advertises a Guaranteed Hours Contract as available, which is unusual in this industry and directly addresses the unpredictability. The Generalist role does not carry that badge. If you qualify for the technical tracks, ask about it. Either way, our guide on pairing AI training income with a steady remote job applies.

Is Stellar AI worth it?

For a non-technical contributor, yes, on balance. The $25 base is at the upper end of generalist AI training work, payment is weekly and reportedly reliable, there is a progression path into reviewer work, and if the reported paid qualification still holds then your downside on applying is close to zero. Compare that with Alignerr, where the entry assessment is often a single unpaid attempt, or Pasiflora AI, whose Bloom onboarding is explicitly unpaid.

For an engineer or ML specialist, the published bands are genuinely competitive with anything in this space, and the guaranteed-hours option is rare enough to be worth an application on its own. The thing to go in clear-eyed about is the pool model: qualifying buys you eligibility, not income. Treat it as one stream, not a plan. See how it stacks up in our roundup of AI training platforms that pay.

Frequently Asked Questions

Is Stellar AI legit?

Yes. Stellar AI publishes Terms of Service and an open roles page with explicit pay bands, charges nothing to join, and pays weekly via PayPal. Independent reviews and first-hand contributor accounts converge on the same picture with no fraud allegations found. The gaps are that country eligibility and company leadership are not published.

How much does Stellar AI pay?

Stellar publishes rates by role: $25/hr and up for Generalist, $35 to $100 for Junior Software Engineer, $70 to $160 for Senior Software Engineer, and $80 to $200 for Machine Learning Engineer. Its FAQ confirms a $25 base rate. Payment is weekly via PayPal. Ignore the "$25 to $40 an hour" range repeated elsewhere, the $40 is a reported qualification payment, not an hourly rate.

Does Stellar AI pay for the qualification test?

A first-hand contributor account reports being paid $40 to take a project qualification, but Stellar does not document this anywhere on its own site, and that report is roughly 20 months old. Separately, the Senior Software Engineer listing does advertise a $600 qualification bonus paid on passing, which is a different mechanism and applies only to that track. Ask what a qualification pays before sitting it.

How do you apply to Stellar AI?

Register at joinstellar.ai, share your background and skills, complete the skill-match test, sign the contractor agreement if matched, and add PayPal details for weekly payment. You must be 18 or older, fluent in English, and have a reliable internet connection. No prior experience or coding skill is required for the generalist track.

How long does it take to get work on Stellar AI?

There is no set timeframe, and Stellar says so directly: contributors are onboarded from its annotator pool on a rolling basis, only when a project matching their skills becomes available, with no estimates given in advance. Some people report being accepted and working within days; others wait indefinitely. Passing the test gives you eligibility, not guaranteed work.
