Solo Founder Launches Kanjideck Physical Kanji Deck
|
5.1
A solo developer launched Kanjideck, a Kanji learning card deck, on Kickstarter in January 2026 after prototyping an HTML-based Anki deck starting August 2024 and producing physical prototypes in September–October 2024. They used MakePlayingCards.com for prints, programmatic PDF-to-PNG tooling (Playwright, ImageMagick), iterated JLPT-tiered decks and packaging, and formed a U.S. company to meet Kickstarter requirements.
