Overview

Pro includes these exclusive features:

• Offline Traditional Chinese conversion: convert results to Traditional Chinese automatically
• Hotwords management: unified hotword injection across providers to improve recognition for proper nouns
• App-specific prompts: automatically switch AI prompt preset by foreground app
• Continuous speaking mode: VAD auto start/stop without manual control

Offline Traditional Chinese Conversion Pro

Automatically converts Simplified Chinese transcripts to Traditional Chinese.

Highlights

• Smart conversion: offline conversion algorithm
• Seamless: runs automatically without hurting recognition speed
• Global: works for all providers and input scenarios

How to use

1. Open BiBi Keyboard Pro settings
2. Go to Settings → Input Settings → Pro features → Convert to Traditional Chinese after recognition
3. Choose a rule:
   • Standard
   • Taiwan usage
   • Hong Kong usage

Note

Conversion applies after all other text processing (including AI post-processing), ensuring final output is Traditional Chinese.

Hotwords Management Pro

Manage custom hotwords to improve recognition of proper nouns, brand names, names, etc.

Highlights

• Multi-provider support: auto-adapts hotword formats per ASR provider (local models and ElevenLabs are not supported)
• Inject into AI prompts: one-tap inject hotwords into selected AI post-processing prompts
• Unified adaptation: for providers without native hotword support, hotwords are structured and injected into recognition prompt parameters

How to use

1. Open BiBi Keyboard Pro settings
2. Go to Settings → ASR Settings → Result Optimization (Pro)
3. Add/import hotwords (supports batch import from clipboard)
4. Save to apply

Avoid too many hotwords. Per-provider limits apply and excessive lists may hurt performance.

What’s new (more convenient)

• Clear all + undo: clear your hotwords in one tap, with an "Undo" action in the snackbar
• Add from selection menu: select any text in any app, then choose "Add hotword to BiBi Keyboard" to add it instantly

Continuous Speaking Mode Pro

Based on VAD (Voice Activity Detection): automatically starts on speech and stops on silence.

Highlights

• Auto start: after tapping mic, recording starts when speech is detected
• Auto stop: stops when silence is detected and runs recognition
• Continuous: multiple rounds without tapping repeatedly
• Tunable: configurable silence window and sensitivity

How to use

1. Open the BiBi Keyboard Pro panel
2. Add the continuous mode button under Settings → Input Settings → Custom action buttons, then toggle it on the keyboard
3. Start speaking
4. Tune VAD parameters:
   • Silence window: 0.5-3s (default 1.5s)
   • Sensitivity: 1-10 (default 5)

Notes

• Continuous mode keeps the mic listening longer and increases battery usage.
• In very noisy environments it may false-trigger; consider switching back to press-and-hold.
• It may take a word or two to detect speech and start recording.

Omni-direction Cursor Sliding Pro

Enables omni-direction cursor movement via sliding on the space bar.

How to use

1. Enable Settings → Input Settings → Pro features → Cursor sliding mode
2. On the keyboard, start from the space key area and swipe up to trigger cursor sliding
3. The mic icon turns into four directional arrows
4. Swipe up/down/left/right to move the cursor; the cursor follows your finger position

WebDAV Auto Backup Pro

Automatically backs up all settings to WebDAV storage for multi-device sync.

Highlights

• Scheduled backup
• Multi-device: restore on another device by signing in with the same account

How to use

1. Open BiBi Keyboard Pro settings
2. Go to Settings → Backup
3. Enable Auto backup
4. Fill in WebDAV:
   • Server URL: e.g. https://dav.example.com
   • Username
   • Password
   • Backup interval
5. Check backup status and last backup time

Note

WebDAV backup content is the same as manual backup. Only one config file is stored on the server.

Regex Post-processing Pro

Apply regex rules to recognition results for advanced text transformations.

Highlights

• Full Java regex support
• Chained rules: apply multiple rules in order
• Templates: one-tap common templates with auto-filled notes
• Notes: notes are for display/management only (do not affect matching)

How to use

1. Open settings
2. Go to Settings → ASR Settings → Result Optimization (Pro)
3. Enable and tap Add rule (or use Templates)
4. Fill in:
   • Pattern: regex
   • Replacement: replacement text ($1, $2, etc.)
   • Options: ignore case, multiline, etc.
   • Note: a label for list display (does not affect behavior)
5. Save; rules apply sequentially

Note

Regex post-processing runs after AI post-processing. It is useful for normalizing AI output formats.

App-specific Prompt Pro

This feature is only available in Pro

Assign different AI post-processing prompt presets per app. Example: use "General post-process" for chat apps, "Basic polishing" for notes, and "Extract to-dos" for task tools.

How to use

1. Open Settings → AI Post-processing
2. Tap "App-specific Prompt (Pro)"
3. Enable "App-specific Prompt"
4. Tap "Add app" and select a prompt preset for that app

Notes

This requires enabling BiBi Keyboard’s accessibility service to detect the foreground app. It does not read your chat content or screen text.

Advanced UI Theming Pro

On top of Material 3 dynamic color, Pro adds more color customization options.

• Built-in theme colors: pick theme colors independent of system wallpaper
