Throughline Speed Reader

Train toward your ideal reading pace with intelligent pacing. ORP alignment, natural rhythm, and on-device AI summaries. Words flow to you.

Read faster while comprehending more. Throughline presents text one word at a time with intelligent pacing that adapts to natural language rhythms.

VARIABLE PACING ENGINE Unlike basic RSVP readers that show every word for the same duration, Throughline adjusts timing dynamically: • Punctuation creates natural pauses — longer at periods, brief at commas • Complex words get extra display time • Paragraph breaks give you time to absorb ideas • Not fixed-interval timing — pacing adapts continuously word by word

ORP ALIGNMENT Each word displays with its Optimal Recognition Point at a fixed position on screen: • Your eyes never move — words come to you • The red pivot letter marks the optimal focus point • Eliminates the saccadic jumps that slow traditional reading • Find your ideal reading pace and keep pushing further

WARMUP & COOLDOWN • Start each session at a comfortable pace • Gradually accelerate to your target speed • Cooldown ramp slows gently at the end of texts • Circular toolbar gauge shows ramp progress during warmup and cooldown • Configurable duration and intensity
