Handwriting Repeater vs Kanji Dojo

Handwriting Repeater is a free browser-based tool for practicing written sentences on a digital canvas. Loop Mode repeats writing across a page, while Trace Mode places faint guide text beneath the writing. The pen can be set to three sizes, four types, and eleven ink colours; page options include ten line styles and five colours, including Montessori-style guides and blank pages.

A Type Text panel supports repeated text, seven fonts, and preset alphabet, number, cursive, calligraphy, and signature templates. Save the canvas as a PDF, capture a PNG, or print through the browser. A share link carries the chosen settings so a teacher can send them to students. The canvas expands as lines are added, with no hard repetition limit. Text entered in the canvas stays in the browser and is not sent to or stored on the operator's servers. It works in modern browsers on iOS, Android, desktop, and laptop computers. It requires no account and has no subscription fees.

Kanji Dojo is an open-source app for learning Japanese character writing, meanings, readings, and related words. It covers hiragana, katakana, and more than 6,000 characters. Learners can organize study by JLPT level, school grade, or WaniKani level, including combinations of those paths. Flashcards and spaced repetition support practice, with vocabulary examples, and a searchable dictionary provides character and word lookups. After downloading the learning materials needed, users can continue studying offline. The learning content is free, while some extra features are paid to help cover backend and development expenses. The app is available on Android, iOS, Linux, macOS, web, and Windows. Its privacy policy describes aggregated usage information and crash diagnostics, and says information is not shared or sold to third parties for marketing. The project is community driven, so requested features may depend on an interested contributor. The linked GitHub repository was archived on August 27, 2026, and is read-only.
