Mercor alternatives for AI training work
Compare Mercor alternatives for AI training and evaluation work using current Sidequest data on open roles, advertised pay, fields and screening.
You'll learn
- Mercor is one of several platforms publishing paid AI training and evaluation work; the alternatives differ by field, advertised rate, eligibility and screening.
- The comparison is Sidequest’s live inventory — open listings, advertised hourly rates and the fields each platform is hiring in — read fresh on every visit.
- Where a platform is on the board as a profile entry rather than as vacancies, its row says so rather than printing a blank.
- The right alternative is decided by a specific opportunity: availability, domain fit, rate, geography and screening, not platform reputation.
In this guide
Mercor is one of several platforms that publish paid AI training and evaluation work for domain experts. The alternatives to Mercor that Sidequest tracks — micro1, AfterQuery, Turing, Handshake AI and Ethos, the sites Sidequest tracks alongside it as competitors for this work — differ in the fields they are hiring in, the rates their listings advertise, who can be paid where, and how they screen. The table below is read from Sidequest’s current listings each time this page loads, so the counts and rates are what is advertised today and move as inventory changes.

Open roles counts published vacancies only: a profile entry or an open application pool is on the board but is not a job, so it is not in the count. Rates are the figures listings advertise, aggregated the way the rates page aggregates them; a platform whose listings mix hourly and per-task pay shows no median, because one would misdescribe it. Screening is each platform’s own description of its process, not a measurement of how selective it is.
micro1
Sidequest currently lists 298 open micro1 roles, most of them in Sciences, Languages, STEM and Coding. Advertised rates run a median of $70/hr across 294 hourly listings, up to $400/hr.
- Screening, as the platform describes it
- Profile creation, skills assessment, then an AI interview with 'Zara'. Passing candidates enter the talent pool and are matched as projects open.
- Who fits
- Experts and strong generalists comfortable with fully-remote, task-based work and variable weekly hours. Role types range from evaluation and annotation to red-teaming and rubric work.
micro1 recruits experts and skilled generalists for task-based AI training projects — evaluation, annotation, red-teaming and rubric work — that arrive in waves tied to lab training cycles, and screens with a skills assessment followed by its own AI interviewer. Against Mercor’s credential-first intake it is the alternative to look at when your background is strong but not licensed. The two platforms’ processes are set side by side in Mercor vs micro1, linked below.
AfterQuery
Sidequest currently lists 206 open AfterQuery roles, most of them in Languages, Medical, STEM and Coding. Advertised rates run a median of $75/hr across 204 hourly listings, up to $200/hr.
- Screening, as the platform describes it
- Create an account and apply to a specific listing, or take one unpaid domain assessment to enter a pool matched to a range of paid projects. Some listings add an AI-scheduled interview on top of a resume; assessments and interview requirements vary by listing rather than following one fixed funnel.
- Who fits
- Credentialed professionals in medicine, law, finance, software engineering and the sciences, native-level bilingual speakers for its language and audio work, and skilled generalists for its business-practice and creative listings. Its broader assessment pools accept relevant experience without one specific credential.
AfterQuery pairs credentialed professionals — physicians, lawyers, engineers, scientists, bilingual specialists — with paid work producing the expert reasoning data labs train on. Its board mixes fixed-rate listings you apply to directly with assessment-gated pools, where one unpaid qualifying assessment leads to ongoing matched work in a domain rather than a single role. Read each listing’s kind before applying: a pool is an open application, not a vacancy, and Sidequest badges it as one.
Turing
Sidequest currently lists 221 open Turing roles, most of them in STEM and Coding, Generalist, Sciences. Hourly & per-task mix.
- Screening, as the platform describes it
- Create a free account at work.turing.com and apply directly to a specific listing. Most roles combine a short skills assessment with an async or live interview; the exact bar varies by listing rather than following one fixed funnel.
- Who fits
- Software and infrastructure engineers, PhD/Master's-level scientists and mathematicians, lawyers and compliance reviewers, finance professionals, bilingual analysts, and domain SMEs across fields from healthcare to personal finance to sports — the board runs wide rather than narrow.
Turing runs an open board of contract listings behind the AI labs it serves — software and infrastructure engineering, PhD-level science and mathematics, legal and compliance review, finance, linguistics and a long tail of domain-expert and generalist roles. Many of its listings are paid per task rather than by the hour, which is why Sidequest publishes no hourly median for Turing: an hourly-only figure would misdescribe the board. Most listings state their rate on the listing itself, and you apply to each one directly.
Handshake AI
Handshake AI is on the Sidequest board as a profile entry rather than a set of vacancies: you create a profile and are matched to work, and the rate varies by the opportunity you are matched to.
- Screening, as the platform describes it
- Apply and verify your identity, then get matched to a project based on your background. Project-specific training precedes any paid task. The current program page describes identity verification and project matching; it does not describe a separate live interview.
- Who fits
- US-based professionals and students with work authorization (F-1 CPT/OPT is eligible; STEM OPT is not). No prior AI experience is required for general evaluation work — postgraduate and domain credentials unlock the higher-paying specialist projects.
Handshake AI routes the Handshake college-career network into paid AI evaluation and training projects. It is for US-based professionals and students with work authorisation, and general evaluation work needs no prior AI experience, while domain projects ask for the relevant credentials. The rates it publishes sit on its own program page rather than on a job board, so the card above says what the board holds today.
Ethos
Sidequest currently lists 100 open Ethos roles, most of them in Generalist, Finance, STEM and Coding. Advertised rates run a median of $80/hr across 100 hourly listings, up to $150/hr.
- Screening, as the platform describes it
- Create an account and an expert profile, then verify your identity with a government ID, a live selfie and a biometric facial check before taking part in any project. Ethos uses AI tools alongside human review to evaluate, screen, rank and match experts, and may invite you to a short AI voice screen. You can accept or decline any project it presents. Its expert terms state that it makes no representation about the frequency, quantity or availability of opportunities.
- Who fits
- Practitioners with several years of real industry experience whose knowledge is worth paying for by the hour — lawyers, clinicians, finance and consulting professionals, engineers and researchers. Its own opportunity pages ask for several years of experience in the field. Where you can be paid is decided by Ethos; it publishes no country list.
Ethos is an expert network whose door is a profile: you create one, verify your identity, and are matched — by AI with human review — to expert calls, consulting, research and AI training projects. It also publishes opportunities of its own, and Sidequest currently tracks active Ethos listings across several fields, so the card above reads like any other platform’s: the count and the advertised rates are what is listed today, and both move as inventory changes. Its terms make no representation about how often matched opportunities arrive, so treat the listed roles and the matching route as two separate things to weigh.

Handshake AI is on the board as a profile entry, not a job list, so it has no vacancies to count.
Read this as inventory, not identity. A platform that lists many legal roles today is a platform currently hiring in law, which can change with its next project wave; the fields with the most listings are where an application is most likely to find an open door this week. A platform with no listings on Sidequest may still have work — a profile-entry platform matches from a profile rather than listing vacancies here — but there is nothing on the board to compare it by.
Mercor vs the alternatives: what to compare
| Factor | What to establish | Where Sidequest shows it |
|---|---|---|
| Credential fit | Whether the listing asks for a licence, bar membership, a chartered qualification or a degree you hold — or accepts experience instead. | The requirement line on each listing; the who-fits section of each platform profile. |
| Role availability | Whether there are vacancies to apply to today, or a profile you join and wait on. | The open-roles column above, and each platform’s board filter. |
| Advertised rate | The figure the listing states, its basis (hourly, per task, a band) and whether a trial batch is paid. | The rate column above, each listing’s page, and the rates page. |
| Geography | Whether you can be paid where you are, and any work-authorisation rule such as Handshake AI’s US-only one. | The location line on each listing; the platform profile for platform-wide rules. |
| Screening | How many steps sit between applying and paid work — credential check, assessment, AI or live interview — and what each asks of you. | Each platform profile’s screening section, from the platform’s own description. |
| Project shape | Whether the work is a batch, an ongoing project, or matched as it opens. | The listing itself; where a platform describes onboarding or matching, its profile says so. |
Reality check
The platform with the most open roles is the better Mercor alternative.
More listings means more to read, not more you can get. One platform’s hundred listings in fields you do not work in are worth less to you than another’s five in your field at a rate you would accept and in a country where you can be paid. Compare specific opportunities, and treat passing a screen and receiving paid work as separate events.
