Get a little conversation started

Cat Vocabulary is for parents to use together with preschool children, especially ages 4–5. The app currently has a Chinese interface. The first TestFlight build is being prepared; a public invitation will appear on the product page when available. Availability depends on Apple review and remaining places.

Connect your AI

Open Settings and sign in to ChatGPT, or choose a model provider and enter your own API key. Endpoints and supported models are preset. Your provider’s access, usage limits and billing rules apply; the beta does not include AI credits. Choose the target learning language freely in settings or a child’s profile.

  • Photo: open the camera, take a photo or cancel to return. You can also choose a saved photo. Selected photos are resized and re-encoded before generation.
  • Voice: describe where you are or what you can see. System recognition is the default. Doubao streaming ASR 2.0 and Deepgram are optional, configured with separate ASR keys. Voice input lasts up to 60 seconds and fills editable text.
  • Text: type a short scene, up to 2,000 characters.

Tap Generate to receive words and 3–5 short conversations. A possible child response and Chinese meanings help you choose something to say. Successful results are saved automatically. Review AI output for accuracy; you can correct or delete it. Photos stay linked to the words and conversations that came from them.

Listen and revisit

Use normal or slow playback. System speech needs no API key; cloud speech is optional and configured separately from recognition. Photo review uses parent feedback to schedule another visit. The intervals are adjustable product rules, not a measurement of your child’s memory.

Pro features are a preview in this beta, with no purchase flow: multiple children, old words in new scenes, photo stories, short daily activities, manual family sharing and printable HTML cards or booklets. Photo stories are imagined from saved scene text, not a record of what actually happened. Exported HTML can be printed or saved as PDF in a computer browser.

Keep a copy

Export a backup before changing devices. It includes saved photos and family learning records, but excludes ChatGPT credentials, API keys and sync passwords. File sharing or manual HTTPS WebDAV sync is optional. Deletions are local and can return after merging with a family member’s older copy.
