Conference Presentations

We like to attend and present our work at conferences to share our work with the community and to learn from the community. Our work is our passion and work done in a vacuum does not benefit anyone.


Our email newsletter is very low volume. We use it to primarily keep you up to date on new Philter versions and new NLP models for Philter. We may also include tips or examples on how to get the most out of Philter, and updates to the Philter SDKs and related open-source projects. We encourage users of Philter to subscribe.
