Lingxi IME TestFlight Beta

Lingxi IME (RIMES) is a keyboard and text assistant for your iPhone. Type locally, organize your words in Buffer, and choose optional translation or AI assistance when you need it.

The App Store name is Lingxi IME; the app and system keyboard still display RIMES.

TYPE YOUR WAY

Use Pinyin, Ziranma double Pinyin, Wubi 86, English, nine-key Pinyin, or slide chords. Switch Simplified and Traditional Chinese, explore custom key layouts, and import compatible Rime scheme packages. Expand and scroll candidates, or hold and drag to choose a word.

A BUFFER FOR YOUR WORDS

Compose and edit before inserting text into your app. Tap to insert one block, or hold the insert button for one second to insert all remaining blocks. Explicitly import readable text from the current input field, or tap Paste to add clipboard text to your draft. Text insertion does not send a message for you.

OPTIONAL APPLE TRANSLATION

On iOS 26 or later, Apple translation uses downloaded on-device language models. Prepare the required languages in the RIMES app, then choose a language pair in Buffer. Availability depends on supported languages and downloaded models. Results are inserted only when you choose. No external AI fallback is used when local translation is unavailable.

YOUR CHOICE OF EXTERNAL AI

For optional AI polishing, rewriting and other writing tools, configure your own HTTPS OpenAI-compatible Chat Completions provider, model and API key. The recipient is shown before you grant permission. Only Buffer text you explicitly submit is sent to the configured, consented service. Your provider's data policy applies and its service may require a separate account or payment. RIMES does not include an AI subscription, provider credentials, or a hosted AI service.

PERSONALIZE YOUR KEYBOARD

Manage official Buffer tools, keyboard appearance, custom mappings and status-light pets. Create a typing statistics card from your local typing activity.

LOCAL EVERYDAY INPUT

Ordinary typing and Buffer editing work offline without Full Access, an app account, or a subscription. RIMES has no ads or keyboard-text telemetry. API keys use this device's Keychain. External AI, keyboard clipboard access and image export require Full Access; saving an image to Photos requests add-only photo access. Buffer drafts remain in keyboard-session memory and are cleared when the session ends.

Enable RIMES in Settings > General > Keyboard > Keyboards, then choose it with the globe key. Secure fields and apps that prohibit third-party keyboards use the system keyboard.

Requires an iPhone running iOS 17 or later. Apple local translation requires iOS 26 or later and supported language models. Haptics depend on device and system settings.
