How the products connect
Fulin Labs makes separate products that are meant to be used on their own. Where one of them has a useful next step in another, it links there with the work already filled in, so you do not copy and paste between tabs. This page lists the handoffs that exist today, one per row.
What hands work to what
| From | To | What moves | Where to try it |
|---|---|---|---|
| VocaDeck | ShortLink | A deck shared by link is turned into a short link on ShortLink, so the address stays small enough to paste into a chat. | vocadeck.fulinlabs.com |
| HSK Studio | VocaDeck | Each HSK level page links to VocaDeck’s CSV formatter, which turns a vocabulary list into a CSV or an Anki text file you can study in VocaDeck or import elsewhere. | HSK vocabulary lists |
| VocaDeck | HSK Studio | The same formatter links to HSK Studio’s worksheet generator, which prints HSK words as handwriting sheets with pinyin. | CSV to Anki formatter |
| VocaDeck | HSK Studio | HSK Studio’s pronunciation audio is served by VocaDeck’s text-to-speech service. | hsk.fulinlabs.com |
| ShortLink free tools | ShortLink | The UTM builder, QR code and chat-link tools each offer one tap to shorten the finished link, with it already filled in. | ShortLink free tools |
| SchedulePost | ShortLink | The campaign link built in SchedulePost’s UTM tool can be shortened on ShortLink in one tap. | UTM link builder |
| ShortLink | Reception | The Zalo and Telegram chat-link generator points to Reception’s multilingual spa message templates. | Chat-link generator |
| Reception | ShortLink | Reception’s missed-call calculator points to ShortLink’s chat-link and QR generator for a shop’s booking link. | Missed-call calculator |
| HSK Studio | Reception | HSK Studio’s help assistant is called Reception and reuses Reception’s approved-answer matching. | hsk.fulinlabs.com |
| Fulin Labs | Every product | The free tools directory lists every product’s tools, and the blog carries one guide per tool linking back to it. | Free tools directory |
