Speed Worm - Read Faster, Remember More Are you tired of drowning in unread articles, dense academic papers, and endless reading lists? Meet Speed Worm, the ultimate speed-reading and comprehension trainer. We don't just help you read faster; we train your brain to process information more efficiently so you actually remember what you read. Whether you are a student, a professional, or an avid reader, Speed Worm gives you the tools to conquer any text at speeds up to 1,000 WPM. 5 REVOLUTIONARY READING MODES Find the perfect technique for your brain with our gesture-controlled, auto-saving reading modes: RSVP (Rapid Serial Visual Presentation): Focus on a single central point while words flash at your target speed, eliminating eye movement. Chunk Mode: Train your brain to absorb multi-word groupings (2-6 words) with intelligent boundary detection. Just pinch to resize! Pacer Mode: Follow guided highlighting (background, underline, or box styles) as you read through full texts. Scrolling Mode: Keep your eyes moving smoothly with flowing text that highlights the current word and fades the past. Peripheral Sight: Expand your field of vision with specialized central-word focus training and draggable previews. AI-POWERED COMPREHENSION Reading fast is useless if you don't understand the material. Plug in your own AI API keys (Claude or OpenAI) to generate personalized comprehension quizzes. Test your recall, main idea extraction, inference, and vocabulary directly from your imported texts. DEEP ANALYTICS & PROGRESS TRACKING Watch your skills grow in real-time. Speed Worm tracks your sessions, calculating your average WPM, comprehension percentage, and total time spent. View your 7-day trend charts, get breakdowns by reading mode, and celebrate milestones with AI-generated insights. Want to dive deeper? Export all your statistics directly to a CSV. IMPORT ANYTHING, INSTANTLY Bring your own library.

Extract clean text directly from web URLs and articles. Use your device's "Share" intent to send text to Speed Worm from any other app. Organize everything beautifully by category: Technical, Fiction, News, Academic, or Custom. ACCESSIBLE & HIGHLY CUSTOMIZABLE Precision Speed: Dial in your exact reading speed from 100 to 1,000 WPM. Beautiful Themes: Read comfortably day or night with 6 themes (Light, Dark, Sepia, High Contrast, Night, Custom).
