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
Ethos
Ethos fits senior professionals who want to see a rate before they apply and can treat the work as occasional income rather than a paycheck. Every listing carries an hourly figure to the dollar, and the top of the board pays $150/hour for consulting and FP&A work, which is far above what conventional annotation platforms pay. The catch is written into the contract: Section 1.4 of the Expert Terms disclaims any warranty on the frequency, quantity, type, or availability of projects, so the advertised “up to $3k/week” is arithmetic on a 20-hour ceiling, not an offer. Getting in means a recorded AI voice interview and, per workers, a qualification screener with a pass mark, none of which is paid by default. If you need predictable weekly hours, this is the wrong platform.
Best for
- Senior professionals with a named-firm background who want a published rate before applying
- Consultants, FP&A leads, and domain specialists who can charge $100 to $150 an hour
- People wanting occasional supplementary income rather than steady hours
- Anyone comfortable with a recorded, AI-evaluated voice interview
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.
