AI training jobs vary a lot depending on the platform. To understand how different they really are, I tried several with different types of tasks — from evaluation to legal AI work and voice training. Here's a plain breakdown of what I found.
Mercor
Mercor offers some of the highest-paying opportunities, especially for specialized roles. Generalist Italian tasks paid around $30/hour; advanced roles like Italian legal AI training reached up to $85/hour; legal translation tasks were around $70/hour. The catch is that Mercor is selective — you need to pass interviews and show strong reasoning, especially for the higher-paying roles.
Gloz
Gloz focuses on subtitle evaluation, particularly for streaming platforms. Pay is time-based, starting around $1 per minute and dropping to about $0.65 per minute. The work mainly involves reviewing subtitles for quality and accuracy. Relatively accessible, but earnings depend heavily on speed and consistency.
Outlier
Outlier is one of the best-known platforms for advanced work. In my case, legal AI trainer tasks paid around $60/hour. The work is more complex than on beginner platforms — reasoning, evaluation, detailed feedback. Not beginner-friendly, but the pay reflects the higher expectations.
Invisible Technologies
Invisible offers more structured projects than typical gig platforms. One example was voice training work at around $20/hour. The environment feels closer to a real remote job, with clearer workflows and expectations — though the pay is lower than top-tier platforms.
TransPerfect
TransPerfect offers smaller, task-based work. Audio evaluation tasks in Italian paid around $1 per task. These are usually simple, but the pay is significantly lower than other platforms. It can be a starting point, not a path to higher earnings.
what this shows
Not all platforms are equal. Some offer high pay but require strong skills (Mercor, Outlier); some offer moderate pay with more structure (Invisible); some offer lower pay but easier access (Gloz, TransPerfect). The biggest difference isn't just the platform — it's the level of work.
the short version
Trying multiple platforms is the best way to understand how this industry works. Higher pay usually comes with more complex tasks, stricter requirements, and selective onboarding. Lower-paying platforms are easier to access but offer limited long-term growth. Start where you can, then move toward better opportunities as your skills improve.
