  All data is processed locally. User can interface with semantic-search app via [[./src/interface/emacs/semantic-search.el][Emacs]], API or Commandline

** Dependencies
   - Python3
   - [[https://docs.conda.io/en/latest/miniconda.html#latest-miniconda-installer-links][Miniconda]]

** Install
   #+begin_src shell
   git clone https://github.com/debanjum/semantic-search && cd semantic-search
   conda env create -f environment.yml
   conda activate semantic-search
   #+end_src

** Run
   Load ML model, generate embeddings and expose API to query specified org-mode files

   #+begin_src shell
   python3 src/main.py --input-files ~/Notes/Schedule.org ~/Notes/Incoming.org --verbose
   #+end_src
