OpenTrain AI
OpenTrain positions itself as one profile for the whole industry. Most of its board re-lists other platforms' roles (869 of its 904 listings on 3 Nov 2026 came from micro1, SuperAnnotate's SME Careers, Turing and Handshake, each listed on this site under the platform that posted it), and 35 were posted on OpenTrain itself by the employers that hire through it, each page stating its pay, from audio transcription and document labeling to engineering and coding experts.
Platform-stated
Buying AI training data from OpenTrain AI? OpenTrain AI pricing for AI teams
Is OpenTrain AI legit?
Researched Nov 2026 · 14 sourcesYes. OpenTrain AI is a real US job marketplace for AI training work: it is free for workers, and employers fund each milestone before work starts, paid out to your bank through Stripe. You are paid only when an employer approves a milestone, workers report removals, slow support and late pay, and partner jobs send you to another platform whose terms OpenTrain does not control. It pays $6–$50/hr on its own postings (top $60) (platform-stated).
Listed in our live directory
OpenTrain AI is the trading name of WMD Global, LLC, a Nevada company (its terms, 2 November 2026); LinkedIn lists it as founded in 2022 in Seattle, led by founder and CEO Weston Dotson. Employers post AI training jobs and hire on it, and it lists partner jobs from Micro1, Turing, SME Careers (SuperAnnotate), Handshake AI and Alignerr, finished on the partner's site. On 3 November 2026 its board showed 904 open roles, 35 posted on OpenTrain itself.
Employers fund each milestone up front. When the work is done you request payout, and after the employer approves it OpenTrain pays your bank through Stripe on a daily payout schedule. Workers pay no fees (its terms put marketplace fees on clients). Stripe payouts cover the 120 countries on its list, which leaves out Brazil and China.
Trustpilot 3.9/5 (123 reviews). Read November 2026.
Takes people in 120 countries, by OpenTrain AI's own list (read 3 Nov 2026). Global job board; payouts reach the countries its payout docs list (Brazil and China are not among them; its payout country page, last updated 1 May 2026, read 3 Nov 2026).
No OpenTrain-specific impersonation cases turned up. OpenTrain is free for workers, you apply only at app.opentrain.ai, and support is support@opentrain.ai, which asks you never to send passwords, codes or ID photos. Fake recruiters usually start on text, WhatsApp or Telegram and later ask you to pay.
What people praise
- Many reviewers say payments arrive on time and praise the milestone system as clear and reliable.
- Several reviewers describe clear guidelines, helpful project admins and useful QC feedback.
- OpenTrain answers criticism in public: Trustpilot shows it replied to 80% of negative reviews (read 3 November 2026), at times admitting a bug was on its side.
What people complain about
- Some report late pay: one quality analyst said pay for February and March 2026 arrived more than 60 days late, and only after several emails.
- Workers describe being removed from projects or contracts with little explanation, including one contract ended over a location check.
- Applications can sit in Pending or Under Review for weeks, and support replies are slow or missing.
- Some say rates were cut mid-project or onboarding went unpaid; one said a $4 an hour job was cut to $2.
What has gone wrong
- October 2026. In October 2026 a worker said an ID check failed and chat support did not answer for 48 hours; OpenTrain replied that the failure was on its side and engineers were fixing it. On 16 October it told another reviewer that some applications never got a final decision and that it is fixing how status shows. In September it acknowledged voice AI interviews stuck on 'connecting'.
- November 2025. In October and November 2025, contributors on a Mandarin transcription project and another project said they were removed close to completion. OpenTrain replied that removals follow repeated low-quality or AI-assisted work, and that removed contributors are still paid for their time.
Best for: Annotators and domain experts with AI training work to list who want one free profile for jobs from several platforms and can wait on each employer's review and pay approval. Not for: Anyone who needs steady hours or fast support, works only from a phone, or lives where OpenTrain cannot pay out through Stripe, such as Brazil or China.
Honest catches
- Pay here is platform-stated, not measured live from a job feed, so treat it as a benchmark rather than a guaranteed rate.

What OpenTrain AI pays
Platform-stated · as of 2026-11-03Researched rate card, platform-stated, as of 2026-11-03
Read on 3 Nov 2026 from OpenTrain's own job feed (opentrain.ai/jobs/feed.json, the same 904 listings as its job sitemap) and each role's app page, which says whether OpenTrain re-lists it: 869 are roles of micro1 (364), SuperAnnotate's SME Careers (264), Turing (224) and Handshake (17), listed on this site under the platform that posted them, and 35 are posted on OpenTrain itself, by the employers that hire through it. Pay is set by the hiring company and stated on each page: 34 of the 35 state an hourly rate, one a rate per label ($0.80, French phoneme transcription). The middle posting runs $15 to $22 an hour (the median low and high ends); 25 start at $15 or less and none reaches $100, the top a computational chemistry problem designer with a PhD at $15 to $60. By field: coding, data science and engineering experts (Python) mostly $15 to $40 or $50 (to $60), a CBRN safety RLHF expert $50 to $52, a speech-language pathologist $25 to $45, audio transcription and phonetics $2 to $20, and document, image and fertility-data annotation $5 to $14. The band above trims the extremes (10th percentile of the low ends, 90th of the high ends); the live median and typical range on this page are measured from its open postings every day. OpenTrain's own board summary that day says its hourly roles list up to $400 an hour, which counts the roles it re-lists.
| Role | Kind of work | Researched pay |
|---|---|---|
| Coding, data science and engineering expert (Python) | Coding | $15–$60/hr |
| AI safety RLHF expert (CBRN) | AI Evaluation | $50–$52/hr |
| Speech-language pathologist (speech labeling) | Domain Experts | $25–$45/hr |
| Audio transcription and phonetics | Transcription & Audio | $2–$20/hr |
| Document and image annotation | Data Annotation | $5–$14/hr |

How to get started on OpenTrain AI
Researched Nov 2026Sign up free at app.opentrain.ai as an AI Trainer, let OpenTrain build your profile from your resume (about 30 minutes, ending with an email code that publishes it), then apply to jobs one by one with a proposal (some add an AI interview, an ID check, a location check or a screening course); once an employer hires you, complete each funded milestone and get paid through Stripe after the employer approves it.
Who can join
- A computer. On a phone, a tablet or a browser window narrower than 1,024 pixels you cannot apply or start an AI interview, the trainer workspace asks you to continue on desktop, and most jobs need a laptop for the work itself.
- A resume (PDF, DOC, DOCX or TXT, up to 10 MB, or its text pasted in): OpenTrain builds your profile from it, and a second resume for AI training or data labeling work is optional. In some countries you also need a mobile phone to receive a 6-digit code by text message.
- Be at least 18 years old (its Terms of Service, effective 2 November 2026).
- A bank account in a country OpenTrain can pay through Stripe: 120 countries on its list (last updated 1 May 2026), including the US, the UK, India, the Philippines, Nigeria, Kenya, Pakistan, Egypt and Mexico. Brazil and China are not on it, and OpenTrain says it cannot pay out to a country that is not listed.
- Whatever each job asks for. Employers set the software, data types, label types, languages, experience level, talent type and eligible locations, and the matching engine filters or ranks jobs by them.
- For location-restricted jobs: a profile country that is one of the job's eligible locations, and a browser that shares your current location with app.opentrain.ai. The check runs again on every attempt.
- For jobs that require it: a government ID for an identity check through Didit (or Stripe Identity if Didit is unavailable), which may also ask for a selfie. You get two attempts.
- No fee. OpenTrain says it is 100% free for freelancers, with no fees, no subscriptions and no credit card.
Step by step
- 1
Create a free AI Trainer account
Sign up at app.opentrain.ai with your email and a password of at least 8 characters, then choose I'm a Freelance AI Trainer (the account type cannot be changed later; a wrong choice means a new account with another email). Agree to the Terms of Service and Privacy Policy and select Start Onboarding.
- 2
Build your profile from your resume and publish it
Upload your resume (or paste its text) and OpenTrain's AI fills in your experience, skills, education, work history, location and languages. Then confirm what it left out (your country and city, LinkedIn if you want, your hourly rate, weekly availability and who can see your profile; some countries also verify a phone number by text), fix any section on Review your profile, add a photo or skip it, and enter the 6-digit code OpenTrain emails you to publish the profile. It takes about 30 minutes and saves your progress; you can apply only once the profile is live.
- 3
Find jobs that match your profile
Find Jobs has a Recommended tab ranked by your skills, languages, labeling experience, location and experience level, a Search tab with filters (software, data type, label type, experience level, budget type, hours per week, project length) and a Saved tab. Open the job page and read the required software and data types before applying.
- 4
Submit a proposal
Click Submit a proposal (Continue Proposal if you started one); an incomplete profile has to be finished first. A failed location check blocks the proposal, and if your profile lacks software or data types the job requires, it may not be considered. If the job requires an AI interview it opens first and must be finished; then you enter your bid (hourly, per label or fixed price), see the estimated total earnings and submit it to the employer.
- 5
Complete the AI interview if the job has one
The employer chooses a text chat or a recorded voice interview. It collects details such as your LinkedIn URL, years of AI training experience, weekly availability and past platforms, plus any custom questions. A voice interview cannot be paused, ends if two questions go unanswered, and can be started over once.
- 6
Verify your ID if OpenTrain asks
For jobs that require it, OpenTrain asks after you submit the proposal. In Settings, Verification, give consent and select Verify my identity; Didit checks your ID and may ask for a selfie. Use a clear photo in good light: you have two attempts. OpenTrain keeps the result but not your ID number or images.
- 7
Take the screening course if the job has one
Some employers ask every applicant to complete a short screening course and quiz after submitting a proposal. A Start course button appears on your proposal; your progress is saved, the course shows how many attempts each quiz allows, and you see your score only once the employer releases it.
- 8
For partner jobs, finish on the partner's site
Jobs marked Sourced via Micro1, Turing, SME Careers, Handshake AI or Alignerr send you to the partner's own application; some, such as SME Careers jobs, start with OpenTrain's AI interview first. The partner decides on hiring and sets its assessments, training, pay and contract terms, and you check the status on the partner's site, not in OpenTrain's My Proposals tab.
- 9
Wait for the employer's decision
Your proposal shows Pending Review on the My Proposals tab until the employer acts. It can move to Under Review, Shortlisted or Resume Sent (none of them a hire yet), to Hired (a contract is created), to Declined or Not a Fit, or to Job closed if the job closes first. Employers review on their own timeline, and OpenTrain says it cannot guarantee a response date.
- 10
Set up Stripe payouts and get paid per milestone
In Settings, Payouts, click Add Payout Method and complete Stripe's hosted form (do not create a separate account on stripe.com; your payout country is locked at setup). On each Active & Funded milestone, finish the work and click Complete & Request Payout; once the employer approves, OpenTrain marks it Paid and pays your bank.
AI interview (switched on per job by the employer)
OpenTrain has no single platform-wide test. Employers can require an AI interview on a job before they review proposals, so every applicant answers the same structured questions: commonly your LinkedIn URL, years of AI training, data labeling or annotation experience, weekly availability and the platforms and task types you have worked on, plus any custom questions. Answers are saved to a record the employer reviews alongside your resume and profile, and OpenTrain shows you no interview score. Some employers also ask for a short screening course and quiz after you submit. Jobs can also add an ID check or a location check, and partner jobs run their own assessments on the partner's site.
Format
A text chat or a recorded voice interview, chosen by the employer, inside the proposal window on a computer. In a voice interview you answer out loud, cannot pause, and the interview ends if two questions go unanswered; leaving the tab is flagged for review, and you can start over once. Progress is saved if your connection drops.
How to prepare
- Read the interviewer's first message: it often lists all the questions up front.
- Be specific. OpenTrain's own example of a strong answer is 'I have 2 years of experience labeling text and image data on Scale AI and Labelbox', not 'I have experience'.
- Paste your full LinkedIn URL (linkedin.com/in/yourname); the system checks the format and asks again if it cannot recognize it.
- If you have no AI training experience, say so plainly: a clear 'no' completes the field.
- For a voice interview, use a working microphone (a headset is best), a quiet room and a stable connection without a VPN or strict firewall, and answer as soon as each question ends.
- Fill in your profile first, with a separate AI training or data labeling entry for each project or platform and every tool you used, since employers look for specific software and data types.
Why people get rejected
- Leaving the AI interview unfinished: on a job that requires one, you cannot reach the bid step or send the proposal until it is done.
- Vague answers, or a LinkedIn answer without the actual URL, which keep the interviewer asking.
- Failing the location check: a profile country outside the job's eligible locations, location sharing turned off, or being outside an eligible location when you apply.
- Two unanswered questions or long pauses in a voice interview, which end it.
- Using both ID verification attempts on blurry or poorly lit photos.
- A profile missing the software or data types the job requires, which can mean the proposal is not considered.
OpenTrain publishes no timeline from sign-up to first contract. A proposal stays Pending Review until the employer acts; the employer may still be collecting proposals, shortlisting or waiting on AI screening answers, reviews on its own timeline, and OpenTrain says it cannot guarantee a response date. If a proposal has been pending unusually long, OpenTrain asks you to email support@opentrain.ai with the job link.
Pay runs through contract milestones. The employer funds each milestone before you work on it (Active & Funded). When you finish, click Complete & Request Payout in the Contract tab; the milestone moves to Pending approval, and after the employer approves it OpenTrain marks it Paid and starts payout to the bank account you connected through Stripe-hosted setup. OpenTrain uses a daily payout schedule, and bank processing times vary by country. Payout invoices and job statements are in the Reports tab.
Tips to get accepted
- Add a separate labeling experience entry for every platform or tool you have used, even if the work overlapped: employers filter by software, and each tool listed separately improves your matches.
- Before applying to a location-restricted job, allow location for app.opentrain.ai in your browser and turn on location services; the check looks at both your profile country and where you are now.
- Passing a job's location check does not mean OpenTrain can pay you: a job's eligible locations are separate from the payout country list, so check that list too.
- Check the milestone is funded, and for how much, before you start work: when one reviewer was paid $1 on an $80 task, OpenTrain's reply was that the rate is shown in the milestone's deposited funds.
- Do not delete your profile to start over. OpenTrain told one reviewer that deleting a profile loses your progress and applications.
- Expect waits. Trustpilot reviewers describe proposals sitting in Pending Review or Under Review for over a week, and some for months with no decision; apply to several matching jobs rather than waiting on one.
What isn't public
- OpenTrain publishes no acceptance rate and no timeline from sign-up to first contract: each employer reviews proposals on its own schedule.
- How AI interview answers are judged is not published, and OpenTrain shows applicants no interview score: the employer reviews the answers with your profile and decides, and you see only your proposal's status. OpenTrain support cannot change a result or promise another attempt.
- Pay is set job by job (your bid or the employer's budget), so there is no platform-wide rate; for partner jobs, pay and requirements come from the partner's listing.
- OpenTrain's pricing page lists a 10% marketplace fee on payments to talent and a $9.95 contract initiation fee without saying who pays them. Its terms (effective 2 November 2026) say clients pay OpenTrain's fees on self-serve marketplace projects, on top of what talent is owed, and its careers page says freelancers pay no fees; the terms still allow talent-side fees in general without naming any.
- Whether onboarding, training or interview time is paid depends on the employer or partner; OpenTrain sets no rule (for partner jobs it says to ask the partner).
- Bank processing times after a payout starts are not published beyond 'processing times vary by country and bank'.
