山海同文SHANHAI TONGWEN山海同文SHANHAI TONGWENONE WORLD, ONE VERSE一个世界，共写篇章
Compliance at the core · Stability first · Open by design
Every student gets support that fits.Every teacher gets time to teach.
Shanhai Tongwen is the AI platform for learning Chinese, developed by GACEE for schools, education providers and companies worldwide. Teachers make the calls; AI handles lesson prep, review and progress tracking. Every answer shows its source, and learning keeps going on a weak connection.
The demo runs on test data — no account needed.
One platform
A workspace for every role
One set of courses and data, five workspaces — and each role sees only what is theirs.
AI drafts. You sign off.
Shared by remote teachers, local teachers and curriculum teams
- The lesson studio turns one lesson into a plan, slides, tiered exercises and a quick quiz — each with its sources.
- AI marking and agent proposals wait in your to-do list. Learners see nothing until you sign it off.
- Live classes are set up and the register taken for you; a change or cancellation reaches the whole class in one tap.
About 15 minutes a day, always knowing what's next
For children and adults alike
- The Today page lines up review cards, a recorded lesson, pronunciation and reading, matched to each learner's goal and progress.
- Xiaomo answers only from the course books and shows the source — anything it isn't sure about goes to the teacher.
- Lesson packs download in advance, so practice works offline and syncs when the connection is back.
Rosters, consent, devices and audit on one page
Shared by school leaders, administrators and IT
- Upload a roster and an agent proposes the classes; nothing changes until you approve.
- Parental consent, shared devices and power-cut plans at a glance; IT connects existing systems through Connector.
- Weekly reports and certificates come together on their own, and every approval is written to a tamper-evident audit chain.
Your child's week, in your language
For parents and guardians
- A weekly summary: how long they studied, what improved and how to help at home.
- You only ever see your own child. Messages with teachers are translated, with the original a tap away.
- Sign consent online, decide separately on photos and schoolwork, and withdraw at any time.
Attendance, progress and certificates — at a glance for HR
Shared by HR teams and company admins
- Classes are grouped by role and shift; weekly attendance counts catch-up replays too.
- Once the bar is met, HR requests a completion review; certificates are issued after teacher approval and anyone can verify them by number.
- Billing per class. HR sees attendance and progress — never employees' answers or conversations.
Our principles
AI has limits. Teachers decide.
These three are built into the product, not just written on this page.
Learners see it only after a teacher signs off
AI drafts lesson plans, marking and suggestions; teachers check each item before anything goes out, and every approval is written to the audit chain.
Every answer shows its source
Xiaomo answers only from the course books and materials, and says where each answer comes from. Questions it isn't sure about go to the teacher.
Learning that survives a weak connection
Lesson packs download in advance and sync once you're back online; live classes switch automatically between full interaction, audio with the board, and text only.
How this differs from the usual approach
| Area | Common practice | Shanhai Tongwen |
|---|---|---|
| Where answers come from | The training data of a general-purpose model | The course knowledge graph and the textbooks themselves (TIDAR-KAG retrieval); every answer carries its source |
| Who decides | AI writes and publishes directly | Agents only propose; nothing happens until a teacher or school approves, and every decision is written to the audit chain |
| Data ownership | Data sits with the platform and is hard to move out | Isolated per organisation; data can be exported through Connector at any time — no lock-in |
| Privacy | Learner data may be used to train models | Identifiable data goes only to models within its own jurisdiction (a model gateway picks the model by data class); learner data is not used for training |
| Connectivity | Needs fast, stable internet and recent devices | Offline first; live classes step down with the connection; entry-level Android phones work |
| Quality control | Problems surface through user feedback after launch | A new version doesn't ship if the source rate, error rate or hand-off rate gets worse (AgentOps evaluation) |
Xiaomo, the study companion
Every student gets a study companion
Xiaomo remembers what each student has learned and what still needs practice, and explains it in their own language. The memory belongs to the student — view it, export it or clear it at any time.
The learning loop
- Review
- Explain
- Practise
- Improve
Xiaomo · sample conversation
- Hi Nadia! The tone change on 不 tripped you up twice last time, so let's start there.Lesson 2 · Notes
- Why is it and not ?
- Before a fourth tone, 不 is read in the second tone — so it's .Lesson 2 · Pronunciation card 3
- Does 一 change tone too?
- We haven't covered that yet, and I'd rather not guess — I've passed it to Ms Wang. You'll get a notification when she replies.Passed to Ms Wang

Works with your existing systems
Rosters, grades, calendars, meetings and notifications sync as needed. Personal data leaves the platform only with an administrator's approval, and every sync can be traced.

Trust & compliance
Student data stays where it belongs
Where it is stored, who may use it and how — every point is set out in the Trust Center.
- Data resides in Singapore
- The platform runs in the Singapore region and the deployment configuration enforces it; object storage is never copied to another region.
- Guardian consent
- Minors need a guardian's consent before using AI features, and it can be withdrawn at any time; using photos or learners' work needs separate consent.
- Not for training, not for ads
- Learner data is not used to train any third-party general-purpose model, nor for advertising.
Every status is stated as it is: only assessed, audited or certified items carry a check mark.
How we measure
Measured by outcomes
Not by how many features there are — by these four things.
Learning outcomes
Mastery of each knowledge point, using its lower bound; thin data is labelled as such.
Teacher time
The hours teachers spend each week on lesson prep and marking.
Engagement
Weekly activity and task completion — offline work included.
Operating cost
AI cost per learner per month.
The method is public; results will be published each term together with partner schools.
