Launch millions of tasks instantly

hCaptcha has one of the largest pools on the planet available for your use. Whatever your scale, we can handle it without expensive upfront commitments. Millions of tasks per day are no problem.

Simple API-driven pipelines

Want to integrate human review directly into your business operations? We offer high reliability SLAs, guaranteed capacity, and simple REST APIs.

Optimized for cost and quality

No upfront commitment required

The HUMAN platform uses comprehensive confidence models  to perform sophisticated real-time quality analysis. This allows us to quickly determine both the difficulty of questions and their likely right answer, saving you time and money.

Only pay for the accuracy you need

Not all problems are the same. Annotations for safety-critical tasks may require 99.99% confidence from entirely human workers. Annotations for one beta feature in a mobile game app may only require moderate confidence. You decide.

Provide your own ground truth data or let us build it on the fly

Do you have raw data without a comprehensive verification set? In most cases we can build one for you as tasks run through the system, or create labeled samples for your approval.

Annotation Types

Bounding Boxes

Accurate object detection in images and video

Polygons

Define bounding area for objects

Landmarks

Point annotations for many different use cases

Attribute Categorization

About hCaptcha

hCaptcha is designed to solve the most labor intensive problem in machine learning; labeling massive amounts of data in a timely, affordable, and reliable way.

More data generally produces better results in training machine learning models. The recent success of deep models has led to increasingly large datasets, and hCaptcha serves this need. However, creating large human-reviewed datasets using traditional methods is both slow and expensive.

hCaptcha is a way for companies to get the annotations they require faster, with higher quality and at lower cost than other alternatives.

Private or Public Information

The hCaptcha Enterprise system is uniquely flexible in its design: it can be partially or entirely deployed at the edge of your network if you operate a public cloud or own many data centers.

This can dramatically reduce off-network traffic and costs while retaining all the benefits of management by our 24/7 on-call staff to meet the strictest SLAs.
