About the directory

AI Work Platforms helps people discover platforms offering AI training, evaluation, data work and paid research participation. Coverage is worldwide, including remote contributor networks, local workforces and specialist programmes.

Selection and review

A listing needs readable official evidence of its identity and relevant work. Names, summaries, work categories and contributor links are checked against those sources. Similar brands and renamed services are checked for duplication. Inclusion is not an endorsement or a claim that applications are open everywhere.

Research and evidence review use separate AI agents. The reviewer checks each proposed statement against saved source material, including its date and scope. Unsupported statements are withheld; corrections receive another review. This checks source support, not the truth of every company claim or worker account.

Research covers platform overviews, access rules, advertised pay, worker accounts and independent reporting. A few example roles illustrate coverage; this is not a live job board. A missing platform may be unresearched or still under review. Updates currently happen in research rounds, without a daily refresh schedule.

Suggest a platform or use the correction link on its profile.

Evidence and dates

Official information: What a platform says about its own service, requirements or payment terms.
Worker reports: Selected first-hand public accounts. Research seeks contrasting experiences and excludes company-selected testimonials from independent worker evidence. These accounts are not a representative survey or a platform rating.
Independent reporting: Attributed journalism or research. Allegations, study populations and historical periods remain tied to the report that describes them.
Publication dates and periods: Labels distinguish publication, account updates and the period covered by a study or account. “Newest dated source” sorts by verified publication dates. A worker source has “no verified date” when neither its publication nor the selected account’s date has been confirmed.
Checked and reviewed: Checked is when a source was retrieved; reviewed is when its use here was assessed. Neither date makes an older story current. A profile’s latest check does not mean all its information was refreshed that day.

Reader submissions are separate from researched public accounts and appear only after moderation. Read how publication works.

Reading pay and location information

Rates retain their work type, currency and payment unit. An advertised starting rate, maximum and company-reported average mean different things. A task payment is not converted into hourly earnings, and an example role’s rate is not a platform-wide minimum. Check which time is paid and whether fees or thresholds apply.

Citizenship, residence, application location and physical work location are separate requirements. A language requirement does not establish a country rule. A project’s country list applies to that project; a country mentioned in a restriction is not an eligibility recommendation. Registration, acceptance and access to paid tasks are separate stages.

Checking an application link

Contributor links are traced to official sources. Some lead to another domain used for recruitment or account access. Check the destination in your address bar and follow the platform’s own website to confirm an unfamiliar recruiter.

Before sharing ID or financial details, verify the offer independently. Do not pay someone for the promise of a job or deposit money to release supposed earnings. See the FTC’s job-scam guidance.
