Read faster, comprehend more, and save hours every week with ZipWeasel. We combine scientifically proven speed reading technology with custom accessibility tools to help you boost your WPM (Words Per Minute) without sacrificing comprehension. FIVE POWERFUL READING MODES Find the perfect setting for your brain: Focus Mode (Advanced RSVP) The ultimate speed tool. This mode centers every word on a specific "recognition point" (usually the middle letter). By keeping your eye completely still, you eliminate saccadic eye movements and can triple your reading speed instantly. RSVP Mode (Rapid Serial Visual Presentation) A simpler alternative to Focus Mode. This flashes words one by one in the center of the screen without the specific letter alignment. Perfect for users who find the advanced centering too intense but still want high speed. Anchor Mode (Deep Focus) A game-changer for ADHD and Dyslexia. We smartly bold the beginning of every word to guide your eye through the text block. This artificial fixation point prevents lines from blurring together and keeps you in the flow. Highlight Mode (Visual Pacer) Like a digital finger guiding you across the page. This mode highlights text one word at a time as you read, keeping you on track and preventing regression (re-reading lines) without removing the surrounding context. Chunking Mode (Context Reader) Highlights groups of words (2-4 words) at a time. This offers the best balance between speed and context, allowing you to absorb complex phrases naturally.
