+### Two ways to use BibexPy
+
+| | What it is | Best for |
+|---|---|---|
+| **Full app** (this repo) | `pip install bibexpy` → a local web platform: merge → filter → harmonize → enrich → export → report. | The complete, reproducible workflow on your own machine. |
+| **[BibexPy-Lite](https://github.com/bcankara/BibexPy-Lite)** [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/bcankara/BibexPy-Lite/blob/main/BibexPy_Lite.ipynb) | A lightweight notebook/terminal tool that runs the **same Smart Merge algorithm** — no web UI, no enrichment. | A quick WoS + Scopus **merge** in Google Colab or a terminal. |

+Both share one merge algorithm, so results are identical.
