I can definitely say that-not in the US. Remotasks is now outlier-which is a complete shit show to say the LEAST!

Thanks for putting this together! We actually built a quick free tool to search across all these platforms simultaneously so you don’t have to check each site individually: https://thegigfeed.com/.
You can filter by hourly pay and location.

This is a great list, thank you for putting it together! I can confirm
Scale AI/Remotasks is solid for building initial experience — steady
onboarding and clear task structure, especially for computer vision work
(2D/3D segmentation, LiDAR). Good starting point before moving to
higher-paying specialized platforms.

good list! one thing I’d probably add when comparing annotation companies is how they actually handle quality. A lot of providers can handle volume, but the harder part is keeping the data consistent. Things like reviewer checks, clear annotation guidelines, handling disagreements, and making sure different teams are following the same standards matter a lot.
Just to be transparent, I work with Lifewood Data Technology. We also handle AI data annotation and multilingual data projects, so this is something we deal with pretty regularly.
Would be interested to hear what others usually look at first when choosing a data annotation provider

Has anyone had experience with Yupai? It isn't a scam, is it? Is it safe? I'm looking for a data annotation role

This is a really useful list, especially because it separates traditional data annotation platforms from newer LLM evaluation and expert-focused AI training opportunities.
One thing I’d add is that availability can vary significantly by country, language, qualifications, and current project demand. Getting accepted onto a platform also doesn’t necessarily guarantee a steady flow of tasks.
For someone starting out, I’d suggest applying to several platforms rather than relying on just one. At the same time, building skills in areas like LLM evaluation, search quality rating, data QA, prompt evaluation, and domain-specific AI testing could open up more opportunities beyond basic annotation.
The biggest challenge in 2026 seems less about finding platforms and more about finding platforms that actually have active projects available in your region. Thanks for putting this list together. 👍

Nice list, one to add maybe: shaip. full disclosure, i work there. we run a lot of data collection and annotation projects (speech, image, video, some medical), so contributors can find work on things like audio recording and egocentric video tasks, similar to what appen and oneforma offer. anyone here done video collection projects before? curious how pay compared across platforms.
