Chénjìn沉浸

A Chinese Reader with a Popup Dictionary, for Any Text

A Chinese reader with a popup dictionary turns reading from decoding into flow: tap the word, get the answer, keep going. Chenjin's popup goes deeper than a gloss, and it works on more than a built-in catalog.

Read the graded library, or upload your own texts and books and read those the same way.

A popup that answers the next question too

One tap gives meaning, pinyin, and audio. The tabs behind it give stroke order, the radicals the character is built from and why, the family of words that share its characters, and same-sound words. The question after "what does it mean" is usually "why," and the popup answers that one as well.

Bring your own texts and books

Paste any text, or upload an EPUB or PDF, and Chenjin turns it into a readable lesson: words segmented and linked to the dictionary, pinyin on demand, progress tracked. Uploads stay private to your account, and any signed-in member can use them.

Lookups that become vocabulary

Every word you tap is remembered, and any of them is one more tap from a flashcard, reviewed on an FSRS schedule or sent to your own Anki decks. The words you looked up last month become the words you don't look up next month.

Frequently asked questions

What can I upload?

Pasted text, EPUB and PDF files (DRM-free), and audio. Blank-text audio uploads can be auto-transcribed on the Pro plan, so a podcast episode becomes a readable, tappable lesson.

Are my uploads visible to anyone else?

No. Uploaded books and documents are permanently private to your account, and pasted-text lessons are private unless you choose to publish one.

Does the popup work for traditional characters?

Yes. The reader displays simplified or traditional with one toggle, and every dictionary entry shows both forms.
