Support — TsuiuChat
Last updated: 26 July 2026
Do I need an account?
No. TsuiuChat has no sign-up, no login, and no account of any kind.
Where does the AI actually run?
On your iPhone. The first time you use a feature, the app downloads a small AI model (usually 1–2 GB) and runs it locally from then on. Once a model is downloaded, no internet connection is required to chat.
What's free, and what's Pro?
Free, forever, with no usage cap: unlimited on-device chat, private web search, Apple Image Playground image generation (on supported devices), and connecting your own self-hosted Ollama/LM Studio server.
Pro unlocks: role-play (built-in characters, your own personas, multi-character scenes, scenario templates, community character-card import), cross-conversation memory, a private PDF knowledge base with citations and export, per-task model selection with larger models, fine-grained generation controls, and cloud image generation.
How do I unlock Pro?
A single one-time purchase unlocks everything permanently. There is no subscription.
I bought Pro on another device, or reinstalled the app — how do I get it back?
Open the Pro screen and tap “Restore Purchases”.
Can I use a different AI model for role-play or other tasks?
Pro lets you download additional on-device models (including larger and less-restricted community models) and pin a specific model to each use case — role-play, code, vision, or general chat — from Settings → Local Models.
A model download is stuck or failed. What do I do?
Make sure you have a stable connection and enough free storage (models can be 1–5 GB). The app retries through a backup source automatically if the primary one is unreachable. If it keeps failing, switch networks (for example Wi-Fi instead of cellular) and try again.
Is my data backed up?
Chat content is excluded from iCloud backup by default. You can include it in Settings → Data & Privacy.
How do I delete my data?
Everything lives only on your device. Deleting the app deletes everything — there is no server-side copy to remove separately.

需要註冊帳號嗎?
不需要。TsuiuChat 沒有註冊、沒有登入,也沒有任何形式的帳號。
AI 實際在哪裡運算?
在你的 iPhone 上。第一次使用某個功能時,App 會下載一個小型 AI 模型(通常 1–2 GB),之後都在本機運行。 模型下載完成後,聊天不需要網路連線。
哪些免費、哪些是 Pro?
永久免費且無使用次數上限:無限制的裝置端聊天、私密網路搜尋、Apple Image Playground 生圖 (支援的機型)、連接你自己自架的 Ollama/LM Studio 伺服器。
Pro 解鎖:角色扮演(內建角色、自訂人設、多人劇場、劇本模板、社群角色卡匯入)、跨對話記憶、 帶引用與匯出的私人 PDF 知識庫、依用途指定模型(可用更大的模型)、細部生成參數控制、雲端生圖。
怎麼解鎖 Pro?
一次性買斷,永久解鎖全部功能。沒有訂閱。
我在別的裝置買過 Pro,或重新安裝了 App,要怎麼恢復?
打開 Pro 畫面,點「還原購買」。
角色扮演或其他用途可以換不同的 AI 模型嗎?
Pro 可以下載額外的裝置端模型(包含更大、限制更少的社群模型),並在 設定 → 本地模型 中, 為每個用途(角色扮演、程式、視覺、一般聊天)各自指定要用哪一顆。
模型下載卡住或失敗怎麼辦?
請確認網路穩定、儲存空間足夠(模型可能 1–5 GB)。主來源連不上時,App 會自動改走備援來源重試。 若持續失敗,換一個網路環境(例如改用 Wi-Fi)再試一次。
我的資料有備份嗎?
對話內容預設不納入 iCloud 備份。你可以在 設定 → 資料與隱私 中選擇納入。
怎麼刪除我的資料?
所有資料只存在你的裝置上。刪除 App 就等於全部刪除——伺服器上沒有另一份副本需要另外處理。
