Sites Like DataAnnotation: 9 AI Training Platforms Worth Your Time in 2026

The best sites like DataAnnotation depend on what you bring. If you have years in a profession, start with Ethos and Mercor. If you want general rating and writing work, Outlier, Alignerr, CrowdGen, Mindrift and OneForma are the closest matches.

This is a short list on purpose. It covers nine platforms, each checked on its own pages on 2026-10-12. For each one you get the kind of work, who it suits and how you get in. Not sure where you fit? Start with our top pick in the AI Training Job Matcher.

DigiNo earns a referral when you sign up to micro1, Ethos, Mercor or DataAnnotation through links on this page. Applying through them costs you nothing and does not change your pay.

How We Picked

• Each platform publishes how it works on its own site, and we read those pages on 2026-10-12.
• Platforms whose official pages we could not load today were left out, even if Reddit mentions them.

We do not list pay here.

What DataAnnotation Offers, for Comparison

DataAnnotation pays contractors to evaluate chatbot responses, compare outputs, flag factual errors, write prompts and review code. Work is split into general, multilingual, coding, STEM and professional tracks.

You get one Starter Assessment with no retakes, and the result arrives by email within a few days. The baseline is a bachelor's degree or equivalent experience, fluent English and reliable internet. DataAnnotation pays its contractors through PayPal. See our guides to passing the DataAnnotation assessment and to data annotation jobs.

So a good alternative should offer similar rating and writing work, a clear way in, and a second source of tasks when one queue goes quiet.

The Short List at a Glance

The Platforms, One by One

Mercor

Mercor lists expert roles in business, creative work, finance, healthcare and clinical work, law, management consulting and software engineering.

Mercor's AI interview is run by an AI interviewer that asks role-specific questions, and most take about 20 minutes. You only do each interview once, and the result carries over to other roles that use it. Medical coders and documentation specialists can see how clinical skills are used in our guide to CDI specialist work. Licensed therapists and counselors can see how clinical skills carry over in our guide to bilingual therapist work, and nurses can read our guide to nurse AI trainer jobs.

Mercor works with people in most countries and publishes a list of places it cannot support.

Ethos

Ethos matches professionals to client projects.

Ethos works with experts as independent contractors. Ethos uses AI tools to screen and match experts, and you can turn down any project without a penalty.

Outlier

Outlier is run by Scale AI, and you can read our Scale AI review. Depending on the project, you write prompts, compare AI outputs and evaluate model responses. If Outlier's queue is empty, see jobs like Outlier AI.

Onboarding takes 30 to 90 minutes: set up an account, choose your areas of expertise, pass skill screenings and verify your ID. Bring a valid ID and phone from your country, a current resume and a LinkedIn profile.

Outlier does not sponsor visas. Pay runs weekly on Tuesdays through PayPal, Airtm or bank transfer.

Sources: Outlier FAQ, 2026-10-12.

Alignerr

Alignerr is powered by Labelbox. You sign up with email or Google, upload a resume that fills in your profile, then apply to listed jobs.

Next comes an ID check through Persona. Some jobs add an AI interview or a domain assessment. Approved people sign a contract and set up payment through Stripe Connect or PayPal. It is freelance work, not a full-time job.

Handshake AI

Handshake AI is a fellowship that pays students, professionals and experts hourly to train AI models. No AI experience is required.

Open sign-up is for people based in the US with a work authorization Handshake can support. Outside the US, Handshake says participation is currently invite-only. F-1 students eligible for CPT or OPT may qualify; STEM OPT is not supported.

CrowdGen by Appen

CrowdGen is the contributor platform of Appen, a data company founded in 1996 and listed on the Australian Securities Exchange. Our Appen review covers what contributors report.

You apply, get verified, then pass a qualification for most projects. CrowdGen says most projects need domain knowledge rather than technical skills.

Prolific

Prolific is a research platform, and its AI taskers group gets AI evaluation studies: reviewing outputs for accuracy, fact-checking and giving detailed feedback.

You cannot apply to the group directly. Prolific invites participants with high approval rates and strong past performance to a two-part AI Task Assessment. Failing it does not affect your account, and the group is still being rolled out.

Mindrift (Toloka's Platform)

Toloka's tasks have moved to Mindrift. It says people can join from any country, subject to its published eligibility rules, and it is free to join.

Pay arrives twice a month through Payoneer or Tipalti, for tasks that are completed and accepted.

OneForma

OneForma is a Centific company. Its profile takes about five minutes and needs no resume, then it matches you to projects in annotation, data collection, judging, transcription and translation.

It supports people in more than 100 countries, and each listing names the countries it is open to. Some data collection projects are in person.

Which One Should You Try First?

• Professionals with years in a field should try micro1 and Ethos, then Mercor.
• Generalists with a degree and strong English fit Outlier, and Alignerr also asks for clear written English.
• US-based students and recent graduates can apply to Handshake AI.
• Prolific participants should watch for the AI Task Assessment invitation.

What Trainers on Reddit Say

We read recent threads in r/AiTraining_Annotation and r/DataAnnotationTech that ask for sites like DataAnnotation. The same points come up again and again.

• Sign up to several platforms. Work availability depends on demand for your skills and your past performance, so relying on one platform may leave gaps.
• Applications can sit under review with no word for a while.
• Ignore anyone offering paid access or help by DM. Apply on the platform's own site.
