AI Assistant & Translation
AI Travel Assistant
Where to find it: the "Trip" tab → "All tools" at the top right of the "Tools" section → "AI Assistant" (page title "AI Travel Assistant").
Ask travel questions in natural language — itineraries, sights, food, transport, lodging, visas, culture, and more. The assistant only answers travel-related topics.
How to use it
- An empty conversation shows a welcome card, "Plan trips in natural language, look up local info, and generate to-do lists". Tap a sample question under "Start with these ›" to fill it in.
- Or type directly in "Ask me anything about travel…" and send; the answer appears word by word.
- In cloud mode, the assistant can search the site's blog articles and forum discussions to help answer. The "Sources on YUCTS" cards below an answer are labeled "Article" or "Forum" — tap one to open it in the app. The end of the answer notes "Searched blog articles" / "Searched forum discussions".
- After each answer, up to 6 follow-up question suggestions are offered.
- Long-press any message to "Copy" or "Share" it.
AI Engine
Tap the "AI Settings" button at the top right → "AI Engine" to switch modes (your choice is remembered):
| Mode | Description | Where your data goes | Requirements |
|---|---|---|---|
| Auto (cloud first) | Default. Uses the cloud first (can search site articles) and switches to on-device when offline | In cloud mode, messages are sent to the server | Cloud requires signing in |
| Cloud AI | Always uses the cloud | Messages are sent to the server and processed by an AI service provider | Sign-in required |
| On-device (offline) | Uses Apple Intelligence's on-device model | Fully offline; conversations aren't uploaded | iOS 26 or later on a device that supports Apple Intelligence; no sign-in needed |
- If you try cloud AI while signed out, you'll be prompted to sign in to your forum account or switch to on-device AI.
- On devices that support Apple Intelligence, follow-up suggestions are also generated on-device; other devices use a built-in question bank.
Daily quota
- Cloud AI has a daily conversation quota; Yucts Plus members get 10× the daily quota.
- When you run out, a message tells you; if the server provides a reset time, it says when the quota resets. To upgrade: "Profile & settings" → "Member" → "Upgrade to Yucts Plus".
Conversation history and sync
- The "Sync conversations to account" switch in the "AI Settings" menu (on by default): when signed in, conversations are uploaded and saved automatically; when off, you'll see "Upload declined; the conversation is stored on this device only".
- Tap "Conversation history" (the clock icon) at the top right to open "AI Conversations", where you can continue earlier conversations, swipe left to "Delete" one, or tap "New conversation". Sign-in required.
Turning off "Sync conversations to account" only means your history isn't saved; in cloud mode, your messages are still sent to the server to generate answers. Unsaved conversations are gone once you leave the screen.
AI Itinerary / Packing
Where to find it: "All tools" → "AI Planning" (page title "AI Itinerary / Packing").
- Choose "Packing list" or "Day-by-day itinerary".
- Fill in "Destination", "Season" (spring / summer / autumn / winter), "Days" (1–30), and "Number of People" (1–12), and pick the trip under "Import to trip".
- Tap "AI-Generated". Results are grouped by category or by day, titled "AI-Generated Result" or "Template generation result".
- Check the items you want (the count of selected items is shown) and tap "Import selected items"; you'll see "Imported ✓" when done. Packing lists are added to your packing list, and day-by-day itineraries are added as places in your itinerary.
How content is generated
- By default, on-device Apple Intelligence is used (iOS 26 or later, with it turned on). If your device doesn't support it, built-in templates are used.
- When signed in, a "Switch to online AI (more complete)" switch appears. Turn it on to refine suggestions using site articles (your input is sent to the server). If online AI is unavailable, the app falls back to on-device AI or built-in templates automatically.
Translation
The app can translate articles and forum posts. There are two ways:
Auto-Translate Articles
- Location: "Profile & settings" → "Language" → "Auto-Translate Articles".
- Shown only on iOS 18 or later, and on by default; it automatically translates forum and blog content into your system language.
- When on, titles and forum posts in a language different from your system language are translated automatically.
Manual translation
- On a forum topic or article page, tap "⋯" at the top right → "Translate to…" and choose a language (available on iOS 18 or later).
- After translating, the page shows which language it was translated into; tap "Show Original" anytime.
- Translation currently covers the main post; replies aren't translated.
Where translation happens
| Content | How it's processed |
|---|---|
| Short text such as titles | Apple Translate, on your device (iOS 18 or later). If the language pack isn't downloaded yet, the original text is shown; you can download languages in iOS Settings |
| Forum posts and article text | On iOS 26 devices that support Apple Intelligence: translated on your device |
| Forum posts and article text (other devices) | When signed in, the content is sent to the YUCTS server and translated by an AI service provider; target languages are limited to English, Japanese, Korean, Traditional Chinese, and Simplified Chinese. When signed out, the text can't be translated and an error is shown |
"Auto-Translate Articles" is on by default. If your system language isn't Chinese and your device doesn't support on-device AI translation (for example, iOS 18–25), opening a forum topic while signed in automatically sends the main post to the YUCTS server for translation. If you don't want content sent to the server, turn off "Auto-Translate Articles". See Privacy & Permissions and the Privacy Policy.
Camera translation and translation cards
The travel tools include two more translation features, both processed with Apple's on-device technology:
- Camera translation: recognizes and translates text on menus, signs, or notices through your camera.
- Translation cards ("Common phrases" in All tools): phrases by situation, read aloud in the local language, plus "Want to say something else? Use Apple Translate".
