Independent platform directory

Reviewed AI work platforms, without blurring listings and referrals

Tracked platforms have listing-specific inventory that passes the existing publication gates. Reviewed platforms are researched externally and may have no imported jobs, no active referral link, or unclear public-sharing terms.

Independent and referral-disclosed

Specialist AI Work is not an employer, hiring platform, or official partner of the platforms below. A referral program does not make a platform a verified listing source, and referrals never bypass screening or guarantee work.
