Why we built this
Most reading tools are built for productivity.
Arcaneum Focus is built for understanding.
Speed counters and streak dashboards treat knowledge like a quota. We built something quieter — a reading layer that gets out of the way and lets thought happen.

Access to all sites is what lets Focus work on any page you read.
Seeing “Proceed with caution”?
