🧠 Built for Pure Flow & Direct Mental Dictation

When you type looking at the screen, your brain enters an endless supervisory loop: you generate an idea, type a word, and your visual cortex immediately evaluates it—triggering micro-pauses, premature editing, and broken trains of thought. TypeBuffer removes the visual monitor entirely while you write, letting you think and type in uninterrupted harmony.

The ergonomic & cognitive shift:

⚡ Bypassing the Visual "Supervisor"

Eliminate the urge to pause or micro-correct mid-sentence. Your brain routes thoughts directly from idea generation to motor execution, letting you write at the exact speed of thought.

🧘 Restorative Sensory & Visual Rest

Type with your eyes resting on a distant point or completely closed. Eliminate screen flicker, blue light, ocular muscle tension, and the dry-eye syndrome caused by staring without blinking.

🎯 The Expert Typist Advantage

For typists with honed muscle memory, blind typing transforms the keyboard into an effortless, friction-free mental dictation instrument—free from on-screen visual distraction.

🪄 The Intelligent Safety Net

Pause, and TypeBuffer cleanly flushes your accumulated sentence. If you made a minor typo or started with a language prefix (like en: or fr:), integrated AI instantly polishes or translates your text.

Why isn't blind typing taught to everyone? Traditional touch typing mandates on-screen monitoring because casual typists often commit accidental typos or subtle hand displacements off the home row, which without visual feedback can generate lines of unintelligible keystrokes. But for precision typists with high accuracy and reliable muscle memory, screenless typing shifts from a risk into an extraordinary cognitive superpower.

The Core Pillars

Combining the physical focus of blind typing with the intelligence of modern LLMs.
