Halo

Protects photosensitive users by detecting and warning about flashing content in videos

Imagine scrolling through social media when sudden flashing lights trigger a seizure. For the roughly 3% of people with photosensitive epilepsy, this is a daily risk with no real-time protection available. Meanwhile, millions with ADHD, dyslexia, and reading disabilities struggle through dense online content with tools that either strip meaning or barely help. We built Halo to address both challenges — a dual-purpose accessibility extension that protects people from seizure-inducing flashes and also helps anyone who finds long-form reading overwhelming process information more comfortably and efficiently. What it does? Halo provides real-time photosensitive seizure protection, AI-powered reading assistance and a lot more, all inside your browser. 🔹 Flash Detection: Monitors YouTube, TikTok, Twitter/X, Instagram, and Twitch using WCAG 2.1 luminance formulas. Detects ≥3 flashes / sec, auto-pauses the video, and displays a safety overlay showing flash frequency, count, and timestamp along with a audio clip — all processed locally for full privacy. 🔹 The reading assistant works seamlessly across the web — extracting text from sites like Medium, Wikipedia, news outlets, and blogs using a four-strategy fallback system. It cleans up distractions, then generates clear, concise summaries through Google Gemini. Choose between Quick Summary mode (2-3 sentences) or Bullet Point mode (3-5 highlights) to match your reading preferences. 🔹 For auditory learners and those with visual impairments, our AI-powered Text-to-Speech feature—utilizing ElevenLabs' advanced multilingual model—offers 10 professional voice options with varied accents and emotional tones. Enhance your experience further with the integrated white noise player, featuring calming background sounds to improve concentration while you listen. It’s perfect for simplifying long-form content on articles, research pages, and documentation — especially useful for readers with ADHD, dyslexia, or other reading difficulties, but ultimately helpful to anyone who wants to absorb information more efficiently.
