Please review my Tags Unify module

I am back to learn Elixir, and I am building a pet project to help me with my developer notes and collection of links, and as part of it I need to have a unique tags system

My Solution:

gist.github.com

https://gist.github.com/Exadra37/0cbaf090c152049bdbdffbd331fc7b08

tags_unify.ex

defmodule Utils.TagsUnify do

  @moduledoc """
  This module unifies the given tags, by removing duplicates and merging the
  ones that are similar.

  ## Examples

      iex> "My   Elixir Status, my-elixir-status, myelixirstatus, MyElixirStatus" |> Utils.TagsUnify.string()
      "MyElixirStatus"

unique_case_insensitive.ex

defmodule Utils.UniqueCaseInsensitive do

  @moduledoc """
  Module to take a string or list and return it without duplicates in a case
  insensitive way.

  To bear in mind that `"Elixir, Elixir., Elixir ."` will have each of its words
  to be considered as unique, but if you want each word to be considered has the
  same word, then you are better using `Utils.TagsUnify.string()`.

A Test Example:

iex> tags = Utils.TagsUnify.test_tags_list()
[
    " elixir", 
    " My   Elixir Status", 
    "my     elixir    Status",
    " phoenix   framework ", 
    " phoenixframework", 
    " phoenix ", 
    "   ", 
    "   ",
    " Elixir ", 
    " My-Elixir-Status", 
    "myelixirstatus", 
    "MyELixirStatus",
    "my-elixir-status", 
    "myElixirStatus", 
    " my Elixir status", 
    " my elixir status", 
    " Elixir"
]

iex> tags |> Utils.TagsUnify.list()
[
    "Elixir", 
    "MyElixirStatus", 
    "PhoenixFramework", 
    "Phoenix"
]

Please feel free to suggest improvements, say If I missed something or that my approach is not the best way to go for it.
