AI-powered talent marketplace connecting experts with frontier AI work
Machine-learning models screen and match candidates to remote roles in hours rather than weeks, based on skills, experience and availability.
AI-driven interviews and assessments validate professional expertise before experts are surfaced to hiring partners.
Experts work on flexible, remote projects with rates reported to average around $90 per hour and fast, recurring payouts.
Mercor collaborates with enterprises to design benchmarks such as legal, accounting and software-engineering evaluations for AI agents.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
