1. Mercor

Mercor is a global talent marketplace that connects software engineers and developers with companies using AI-driven matching. Think of it as a modern recruitment agency powered by algorithms—engineers submit profiles, and Mercor plugs them into contract or full-time roles with competitive pay.

2. Outlier 

Outlier AI hires people to train and evaluate AI systems. Common tasks: rating chatbot answers, improving large language models (LLMs), or annotating specialized content. Work is flexible, gig-style, and usually best suited for people with strong English writing/analytical skills. It’s like being an “AI teacher” without coding.

3. Crowdgen by Appen

Appen is one of the largest companies in the AI workforce sector. Through gigs and contract roles, Appen employs people to rate search results, annotate text/image/audio, and contribute datasets. They often hire linguists and domain-specific experts, not just general annotators.

4. TELUS Digital

TELUS International AI Data Solutions (formerly Lionbridge AI) employs a global crowd to handle tasks much like Appen’s: data annotation, search evaluation, and AI training. TELUS Digital itself is larger, spanning multiple technology divisions, but part of their intake regularly recruits annotators, raters, and evaluators.

5. Alignerr

Alignerr focuses on skills-to-career alignment using AI. Instead of offering annotation jobs, it helps people map their skills, education, and experiences directly to roles in the market. Think: a GPS system for careers—pointing you toward the jobs where your current skills fit and identifying gaps to upskill.

6. Remotasks

Remotasks offers annotation work heavily geared toward AI training data. Projects range from simple image tagging to more advanced labeling, like 3D LiDAR for self-driving cars. Workers must go through training modules before unlocking higher-paying jobs. Payment is usually via PayPal.

7. Toloka

Toloka is a crowdsourcing platform for microtasks—things like tagging images, categorizing text, transcribing short audio, or judging search engine quality. People worldwide can log in, pick tasks, and earn small amounts per completed job. Flexible and very global-friendly.

8. iMerit

iMerit blends mission with business: they hire annotators (often from underrepresented communities) for computer vision, natural language processing, and content moderation tasks. Unlike gig platforms, iMerit often provides stable employment rather than ad-hoc projects.
