The two platforms in depth
Mercor
Mercor places credentialed professionals into contract work training and evaluating AI models for labs and enterprises, and it is one of the few platforms in this category that prints a rate on every listing before you apply. If you hold a real credential in medicine, law, finance, software or a research field, the top of its board pays more than any general annotation platform, and contractors say repeatedly that the money lands every Wednesday in the amount expected. The trade is that “project-based” bites hard here: Business Insider reported that contractors on a canceled Meta project were offered a near-identical successor at $5 an hour less, and reviewers describe projects ending while they are still onboarding. You also accept a mandatory desktop tracker that screenshots you, a government-ID background check, and a company whose systems were breached in March 2026. This suits a working professional who wants high-rate contract work alongside other income, not someone who needs a predictable monthly paycheck.
Best for
- Credentialed professionals in medicine, law, finance or engineering with other income
- People who want to see the rate before spending time on an application
- Specialists who can work async around a full-time career
- Anyone who values being paid on a fixed weekly cadence
SME Careers
A real expert network run by SuperAnnotate, with documented weekly pay through Deel. It fits specialists who can wait. Skip it if you need hours soon, because onboarding doesn't come with a start date.
Best for
- Specialists who want a profile in an expert pool and can wait for a project to come up
Which should you pick?
Mercor is a better fit if you have engineering or domain-expert credentials and don't mind an application process before you see any tasks.
SME Careers runs an interview-based application according to its own site — likely the better fit if you have engineering or domain-expert credentials, and the review names which of its own pages says so.
