Study Together Live, Even With No Internet
Up to 30 people can mark up the same Quran together at once — and your notes keep working and never get lost, even with no internet.
Workflow moment
From manual step to owned workflow.
Before this step
Studying the Quran is something people do together — study circles, teachers and students, research groups. At the same time, people on weak or patchy connections cannot risk losing their notes when the signal drops.
Now it runs as a system
People study together with no fuss, and every note is safe no matter the connection. Anyone on a slow or spotty signal can work without worrying about losing their place.
System detail
How the system works
Up to 30 people can write on the same Quran at once and see each other's cursors live, with no clashes when two people edit the same spot. If the internet drops, the app keeps working — your changes save on your device and sync the moment you are back online. Nothing is lost.
