Why InputDojo
Skritter does one thing better than anything else: it grades your handwriting stroke by stroke. InputDojo does not attempt that, so if hand-writing characters is your goal, Skritter is the right tool and this is not a replacement. What InputDojo offers instead is the other half of character learning — meeting them in running text. Import an article, video or file, see how much of it you already know, and tap any character for readings and meaning while your saved words build a review deck. Full HSK and JLPT tracking is free, against Skritter's $14.99/mo.

FAQ
Does InputDojo teach stroke order?+
It shows readings and meanings, not graded stroke practice. For handwriting, Skritter or paper remains the better answer.
Can I use both?+
They complement each other cleanly — Skritter for production, InputDojo for reading mileage and vocabulary in context.
Is the free tier really free?+
The full HSK, JLPT and CEFR tracks are free permanently. Paid tiers add SRS review and AI features, with a 14-day trial.
