Hey HN,<p>I'm curious how folks annotate their data to be used in ML pipelines (NLP/Vision) and what their experiences have been. Production/applied examples with teams of annotators would be great.<p>From folks I've spoken with these seem to be the most common ways:<p>* Custom Solution
* Prodigy
* Dataturks
* Lighttag<p>I'm curious if there are more latent examples leveraging your users such as Google's image captcha.
I built 2 annotation tools for the company I work for.<p>one is web based,<p>the other is a c++ app that can directly annotate videos.<p>the web based one is abandoned, because I found it is difficult to do frame level navigation.
