Learning tools
Interactive tools for understanding something properly — the countries of the world, Japanese script, and how trading strategies actually behave on real prices.

Translate both ways, with furigana, romaji and typing help.
Romaji to hiragana and katakana, and back, exactly.
Spin a real globe and learn where every country is.
Test a gold or forex strategy against real history before you risk a penny on it.
Tools you learn with, not just look things up in
A lookup gives you one answer and leaves. These are built so that using them teaches you something along the way. The 3D Earth Globe puts all 250 countries and territories on a globe you can spin, with each country’s capital, languages, currency and neighbours a click away — and a quiz mode for when you want to test yourself rather than browse.
For Japanese, the Japanese ⇄ English Translator prints the reading above every word and the romaji below it, so a sentence full of kanji stays readable before you can read kanji. The Romaji ⇄ Kana Converter handles the parts that trip learners up — the small tsu, contracted sounds like きゃ and the long-vowel mark — and shows the keystrokes for typing each character.
A trading lab that shows its working
TradeLens is for learning how forex and gold strategies behave before any money is involved. Every buy or sell it shows comes with the exact rules that produced it, a backtest that charges realistic costs, and a held-back period the strategy was never tuned on — the check that tells a real edge from a curve fit. It is an education tool: it cannot place a real order and it is not financial advice.
Free, and nothing to sign up for
Everything here runs in your browser. There is no account, no trial and no upload — which is also why the translator, the kana converter and the trading lab keep working on your own device rather than on someone else’s server.
Frequently asked questions
Are these learning tools really free?
Yes. There is no account, no subscription and no premium tier. They run in your browser, so there is no server cost to pass on to you.
Can I use the Japanese tools as a complete beginner?
Yes — that is who they are built for. The translator shows a reading and romaji for every word, and the kana converter includes a clickable chart, so you can read Japanese text long before you know the characters.
Does TradeLens tell me what to trade?
No. It shows what a set of rules would have done on past prices, with every rule visible. It cannot place orders, gives no personal advice, and past backtest performance does not predict future results.
