How RSVP Reading Works

One fixed reading point, adjustable pace, and fewer chances to lose your place.

Import Your Reading

Load books, documents, websites, articles, or scanned pages directly into Absorb. Your reading content and progress are designed to stay on your device.

Focus on the Pivot

Words are displayed one by one. The red letter is the Optimal Recognition Point (ORP). Keep your eyes fixed there.

Stop Subvocalizing

By flashing words faster than you can pronounce them in your head, Absorb helps you process text visually and focus deeply.
