Master Indonesian in 40 Days is a multilingual open-source book to help learners around the world become fluent in Bahasa Indonesia in just 40 days.
This is part of a global language activism project to elevate Bahasa Indonesia to international status — to one day replace English as the global lingua franca.
This book was initially created using AI to get things rolling. After that, the contributors and I will carefully and honestly transform each part by hand to add a human touch and ensure it meets both my vision and personal standards — all in alignment with my activism.
