Task Design Tools

Create with CML, CSS and Javascript, or use our GUI

Every business has its own unique needs and challenges. The user-friendly form builder allows you to easily create crowdsourcing jobs specific to those needs. More advanced users can take advantage of CrowdFlower Markup Language paired with custom CSS and Javascript - all powered by Twitter's Bootstrap front-end framework.

Automated Quality Control

Trust the results with our confidence score

Quality Assurance can be time consuming and delays getting the final results you want. We have the industry's best QC mechanisms and track everything from contributor response velocity to answer distribution. We assign every unit of completed work a confidence score to help ensure the work you receive has only been done by trusted and proven contributors.

Contributor Targeting

Find the best brains for your microtasks to deliver the best results

Finding the right people for the right job is often difficult and requires a lot of resources. We use our history of 1 billion human judgments across 5 million contributors to determine trust levels within our system. You can also target jobs by skill (e.g., content writing or fashion expertise), geography, or demographic.
