It simply removes all the unnecessary tracking parameter of amazon product page links automatically for example:


https://www.amazon.com/Casio-AE1200WH-1A-World-Multifunction-Watch/dp/B0094B79PA/ref=pd_rhf_gw_s_gcx-rhf-llm-search_sccl_1_4/141-1603512-5084544?pd_rd_w=p2Kdi&content-id=amzn1.sym.24c2fae1-095f-4092-8929-4ffbbe27cd06&pf_rd_p=24c2fae1-095f-4092-8929-4ffbbe27cd06&pf_rd_r=97ZR9JR1EJ4BFYHAATPY&pd_rd_wg=nZvos&pd_rd_r=80ae17db-3d1d-4c24-9fec-408cc6a5733c&pd_rd_i=B09S4WXKZD&psc=1

This long-ass link you get when you click a random tile on the amazon product page, gets turned into:

https://www.amazon.com/dp/B0094B79PA?th=1

The link functions the exact same, and becomes much more easily shareable.
