Mercor vs Handshake AI
In one line each — Mercor: High published rates for credentialed professionals, reliable weekly pay, projects that end without notice. Handshake AI: Rate ceilings published up to $150/hr, and a documented pattern of suspensions leaving finished work unpaid. Below, the two compared side by side. Every claim on this page is sourced in the full review it comes from, and each review names where its figures came from and what they leave out.

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
Handshake AI
Handshake AI is the most transparent platform in this category about what it advertises and the least forgiving about what happens if it decides you broke a rule. Every role page publishes a ceiling, from Up to $25/hr for an India-based software engineer to Up to $150/hr for a STEM professor listing, and payment runs on ordinary contractor rails through Stripe on a weekly cycle. The risk sits at the other end of the relationship. Business Insider reported in March 2026 on five contractors suspended without warning on OpenAI projects, four of whom were not paid for completed work, and Handshake's own policy documents make that outcome contractual rather than accidental: on a confirmed LLM violation the work is rejected, the time is unpaid, and you can be removed from the program. Take it if the money is upside on work you would find interesting anyway; skip it if you are counting on the money.
Best for
- Specialists with a credential in a field on the board who want a published ceiling before applying
- People treating the income as upside rather than rent money
- Anyone whose workflow involves no AI writing, grammar, or formatting tools
- US-based applicants, and non-US applicants willing to work at a lower ceiling
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.
Handshake AI 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.
