A platform which enables crowd-sourced annotations for data sets of any size to be used for machine learning.

Mission Statement

Accelerate the spread of machine learning to small- to mid-size companies


One of the largest barriers to companies trying to integrate machine learning into their business is access to a gold standard set of annotated data. We at DataSense want to help businesses overcome that hurdle and thrive with data analytics.

Design Goals

Fair Compensation

Your time is valuable — we vow to always pay our users fairly

Data Integrity

Low-quality annotations hurts both sides


A wealth of annotation types will attract the best clients

Ease of Use

Simple interfaces accelerate the rate of annotation
