Real-world Case Studies

  • S&P Global: Makes markets more transparent with spaCy and Prodigy in a high-security environment.
  • The Guardian: Approaches quote extraction from news articles with spaCy and Prodigy.
  • Nesta: Processes 7m job ads to shed light on the UK’s labor market with spaCy and Prodigy.
  • Love Without Sound: Helps music industry law firms recover millions with spaCy and Prodigy.
  • Posh: Deploys a customized Prodigy cloud service to build financial chatbots for banking conversations.

What others say

  • Christopher Ewen: "Having a small model makes it much easier to achieve our strict inference SLAs. The system is much less operationally complex because the model is so efficient. Prodigy lets us automate as much as possible and focus on valuable decisions and less clicking."
  • Andy Halterman: "A lack of labeled data held geoparsing back for years. It took a week to fix that with Prodigy."
  • India Kerle: "Our current work on measuring the greenness of jobs at the skill-, occupation- and industry-level relied heavily on Prodigy’s flexible custom recipes to incorporate Large Language Models (LLMs) in the labeling process."
  • Anna Vissens: "The principle of human-in-the-loop machine learning is everywhere in journalism. For our AI projects, our data science team developed a fully customized hybrid rules and model-based annotation workflow with Prodigy."
  • Cheyanne Baird: "Prodigy’s design aspect was key. [With my previous annotation tools], I would get a lot of feedback from annotators, saying ‘it’s really hard, because I have to scroll and scroll and scroll to see the labels. There’s too many labels. There’s too many options.’ When I was looking at Prodigy I liked it because you could customize it."
  • Raphael Cohen: "Prodigy is by far the best ROI we had on any tool!"
  • Daniel Bourke: "We love Prodigy! I've tried many data labelling tools and chose Prodigy specifically for the simplicity. Image folder plus text file to database is perfect for our needs. If a model is one of our main products, good data is basically the same as good code."
  • Antonio Polo de Alvarado: "I have been working with Prodigy these last few weeks and I can say that it is probably (if not the best) one of the best NLP tools."
  • Rebecca Bilbro: "Prodigy’s interface is incredibly intuitive! It elevates data labeling to a first-order concern in the ML workflow, enables us to collaborate on measures of inter-rater reliability and makes the labeling options super unambiguous for data annotators."
  • User Survey Participant: "I really love being able to do almost everything in Python, it means that team members with no front end experience can create tasks super easily."
  • Jordan Davis: "What I love about Prodigy is that it makes it really easy to try out ideas. You often don't know whether something works until you try it. Prodigy lets me iterate on my label schemes and definitions, and build much better models this way."
