This Is Why

We Should Work Together


We understand that information security is a key concern, especially in an industry as niche as artificial intelligence. That’s why we have designed a system that involves multiple layers of security checks to take place, manually and automatically.


Garbage in, garbage out. The accuracy of our results is the forefront of our work because we know how important it is to the solutions that you develop for your users and clients. We always aim to deliver highly accurate datasets with a combination of automated quality control features and a human intelligence team that is hand-picked and fully managed.


Our solutions and workflows are built to scale with each project that takes place. Large projects are split into microtasks to increase security and efficiency while automated distribution and selection ensure that the right people are chosen to work on each task. With multiple proprietary products to support growth, we can start as soon as you are ready.

Happy Stories

My working experience at Assignments Source has been different than other online jobs, it feels like one big family! I also enjoy that the different projects allow me to continuously learn new things.

Evelyn Jimenez


Being an Assignments Source worker means that I get to stay home and take care of my new born baby while earning a side income and work with all different types of jobs and companies!

Debra Peters


What I like most about being an Assignments Source worker is the opportunity to work flexible hours. As long as I pay attention to the results and get my work done, it doesn’t matter if I start at AM or noon…

A laptop and a stable Internet connection is all you need.

The only way to find out if we’re as good as our clients say we are is by setting up a trial.
