The Letter Trace

The Letter Trace Chrome extension helps you practice Japanese calligraphy by tracing characters on-screen. It supports vertical and horizontal writing, multi-line text, adjustable character spacing and line spacing, and a rich font library including Kaisho and Pen styles. You can freely change background and text colors, and switch to a clean-write mode with maximum brightness for distraction-free tracing.

It is ideal for gift-envelope inscriptions, penmanship practice, and general handwriting improvement. The extension offers fine-grained spacing controls to tailor text to your needs and is designed for easy use on desktops and tablets, with ongoing improvements based on user feedback.
