Chinese for Polyglots Adding Mandarin

Chinese for polyglots is a tooling question, not a method question: you already know how you acquire languages, and you want an input source that respects your workflow instead of imposing one.

Chenjin is that source for Mandarin: a graded reading and listening engine with lookups, tracking, and flashcards that plug into whatever system you already run.

Chinese for polyglots: the Chenjin library of graded Mandarin articles from HSK 1 to 7

Comprehensible input, on tap

The library grades hundreds of real articles from HSK 1 to 7, each with a familiarity meter computed from the words you know. Pinyin, glosses, and translations are toggles you control, so the scaffolding retracts at exactly the pace you retract it.

Feeds your system, or replaces it

Every word and sentence you meet is one tap from a card. Send cards straight to your own Anki decks via AnkiConnect, or use the built-in queue, which runs FSRS-4.5 with zero configuration. Your reviews, your rules.

The two walls other languages didn't have

Tones and characters are what make Mandarin different from your last language. Tone Coach overlays your pitch curve on a native speaker's, and the dictionary breaks every character into its radicals with the reason it's built that way. Both walls come down with the same volume approach you've used before.

Frequently asked questions

Can I skip the beginner track?

Yes. There's no track. Bulk-mark whatever vocabulary you already have, and the familiarity meters place you honestly from day one. Everything is a library, not a course.

How does Mandarin compare in difficulty to European languages?

Grammar is friendlier than most polyglots expect: no conjugation, no gender, no cases. The time sink is reading, which is why an input platform built around characters is where the hours should go.

Does it get out of the way?

That's the design. No lesson gates, no forced review sessions, no mascot. Reading, listening, lookups, and cards, with stats if you want them and silence if you don't.
