Your family writes in Chinese, you write in English — MochiChat automatically translates every message into the language the other side reads, right in the same group. No switching apps, no copy-paste. The group keeps chatting as usual.
Why it works
The moment a message is sent, its translation shows up in the same conversation, visible to everyone. Nothing to download, no account to remember — grandparents can use it too.
Chinese messages are translated into the other language, and replies are translated back into Chinese. The bot works out who is writing in which language by itself — no commands to type.
Photograph a medicine bag, an appointment slip or an instruction sheet and Mochi reads the text on it, then translates. Reading a photo takes more effort, so translating one uses 50 messages of your monthly credit. This feature is off by default. To turn it on, open your 1:1 chat with Mochi, tap Settings, pick the group, and set Photo translation to On.
Two steps, one minute
Scan the QR code below, search for @973qbaxn in LINE, or tap this link to add “翻譯小年糕” as a friend.
In the group, tap “Invite” → choose 翻譯小年糕. It starts translating the moment it joins; the default pair is Traditional Chinese ⇄ Indonesian.
When the bot joins, it posts a card in the group. Tap “開始使用” (Get started) on that card and choose your languages — the group switches to them right away. To change them later, open your 1-to-1 chat with the bot and tap “Settings” in the menu.
Each group has one language pair. Change it any time.
Chinese is not required: set the main language to Thai and the translation language to Indonesian, and you have a Thai ⇄ Indonesian group.

Upgrading from the Care plan credits your remaining days to the new plan — nothing is wasted.
After the trial there is a 2-day grace period, during which the bot posts a subscription notice in the group. If you don’t subscribe, translation simply pauses — nothing is charged.

FAQ
We only collect the basic data needed to run the service, and we use service providers to help process translations. For details, see the Privacy Policy (Traditional Chinese).
Traditional Chinese, Indonesian, Vietnamese, Filipino, Thai, English, Japanese, Korean, Spanish, French, Italian, German and Portuguese — 13 languages in total. Each group has one pair at a time, and you can change it in Settings whenever you like.
Say someone writes Indonesian in a “Chinese ⇄ English” group: the bot translates it into both Chinese and English, so both sides understand and nobody is left out.
It is AI translation. It is good enough for everyday family messages (medicine, pick-ups, groceries, arranging times) and it understands emoji and casual speech. It is not a professional translator, though — for medical, legal or contract documents, please have a professional check.
Yes. Open your 1-to-1 chat with the bot, tap “Settings” in the menu at the bottom of the chat, pick the group on the settings page and set “Mode” to “Off”. The bot then stops translating the group’s messages; set it back to “Translate” to resume.
Each group gets 3,000 messages a month. It is the same on every plan and it is not shared — adding another group does not reduce it. A normal family group never gets near it; the bot warns you as you approach the limit, and the count resets on the 1st of every month.
After the 3-day trial there is a 2-day grace period, during which the bot posts a subscription notice in the group. You can also start it yourself: open your 1-to-1 chat with the bot, tap “Settings” in the menu at the bottom of the chat, pick the group, tap the “Subscription” button in the “Subscription” section, choose “Monthly” or “Yearly”, tap a plan, enter an email for the receipt, tick “I agree to the Terms of Use and Privacy Policy” and tap “Go to payment” to subscribe by credit card (recurring ECPay charge). After that it renews automatically. If you don’t subscribe, translation pauses by itself and nothing is ever charged.
You can cancel yourself, effective immediately: open your 1-to-1 chat with the bot, tap “Settings” in the menu at the bottom of the chat, pick the group, tap the “Subscription” button in the “Subscription” section, then “Cancel subscription”. No further charges are made and the service runs until the end of the paid period. If you have trouble, email hello@mochichat.app. Please note: removing the bot from a group does not refund the period you have already paid for. If, 3 days before the next charge, the bot is in none of the subscription’s groups, we cancel the subscription automatically (no further charges) and notify the payer. To stop right away, cancel under “Subscription” as described above. Full rules in the Refund Policy (Traditional Chinese).
Yes. Refer MochiChat to a friend or family member who needs it too, and once their first payment succeeds, both your service and theirs get 30 more days. See how referrals work →
MochiChat is a small tool we built. We hope it works as well for you as it does for us, and more services are on the way.
