About Us


Watchdog is a multidisciplinary team of journalists, researchers and software engineers, operating under the Appendix umbrella. We hunt misinformation, investigate matters of public welfare, and build software tools.

We began in April 2019, days after the Easter Sunday bombings in Sri Lanka, as a group of concerned citizens trying to counter misinformation. We did this amidst government crackdowns on freedom of expression and mass hysteria caused by fake news and rumors, building a mobile app that was used by over 200,000 people to verify information and counteract rumors in their own networks.


How we work

We've been called an “open-source intelligence research collective”, and that's fairly accurate. We use a lot of OSINT techniques - a combination of data scraping, analysis of publicly available documents and datasets, paired with old-school boots-on-the-ground journalism.

As a core part of Appendix, we also design and act as a testing ground for new technology. This includes work like the #AskWatchdog AI and various parts of our data scraping, information extraction and archive operations.

These are our Operational ethics. Here’s how we go about Handling conflict - whether that’s related to a story we’re working on or an internal issue. Lastly, we’re known for our no-bullshit style (which tends to annoy people who expect flowery abstractions and vagueness), so here’s our Language guide.

Who we are

The original incarnation of Watchdog was staffed by volunteer factcheckers and translators. We’ve grown significantly since then. Many of our team have strong journalism and research backgrounds, with a sprinkling of computer science to make sure we have the tools to keep up with our ambitions.
