 ## Features
 
 - **Natural**: Advanced Natural language understanding using Transformer based ML Models
 - **Local**: Your personal data stays local. All search, indexing is done on your machine[\*](https://github.com/debanjum/khoj#miscellaneous)
 - **Incremental**: Incremental search for a fast, search-as-you-type experience
-- **Pluggable**: Modular architecture makes it relatively easy to plug in new data sources, frontends and ML models
