Kanji Monster
Turn kanji practice into a game you'll actually finish.
Learn more →No signup, no paywall, no clutter. Just focused tools that help you learn a skill, enjoy a hobby, or get a straight answer, and everything is free.
Each one does a single job and does it well. Open any tool for free, with nothing to install and no account required.
Omnu is a small independent studio that builds free web tools that respect your time. The idea is simple. You pick one genuinely useful thing, build a tool that does exactly that, and get out of the way. No sprawling dashboards, no ten-step onboarding, no popup asking you to create an account before you can try anything. You open a page and it works.
We build for learners and hobbyists. That means the person memorizing their first hundred kanji, the one who wants a quick answer without wading through pages of preamble, and the one picking up a hobby and looking for a tool that helps rather than upsells. Those people are usually underserved by software, because their needs don't map neatly onto a subscription. A focused free tool can help them far more than a heavyweight app they'll abandon in a week.
Everything we make follows the same principles. Tools should work instantly, in the browser, on whatever device you already have. They should stay free rather than locking the useful parts behind a paywall. They should do one thing, so they stay simple enough to actually finish and small enough to load in a blink. And they should be honest, with no dark patterns, no manufactured streaks designed to keep you anxious, and no data you didn't agree to hand over.
The topics are deliberately broad. One month it might be a Japanese kanji drill, and another it might be a tool for a hobby or a plain-language answer to a common question. What stays constant is the character of the tools rather than the subject. They are lightweight, focused, free, and built to be opened again tomorrow. If a tool earns a place in your routine, we've done our job. That is the whole studio in one sentence, small tools that do one thing well and are worth coming back to.
