What is On-Device AI?

ListAIse offers two AI modes: Cloud AI (default) and On-Device AI. Cloud AI sends the request to a remote service for processing. On-Device AI uses the installed local model for supported tasks and keeps that request on your phone.

Cloud AI

No storage needed
Always up-to-date model
Requires internet
Data processed remotely

On-Device AI

100% private
Works fully offline
Instant after warm-up
Requires 3 to 4 GB of storage

Which AI am I using right now?

Open any list, add an item by voice, and look at the small label below the item while it processes. It shows either "On-device (Gemma)" or "Cloud" to tell you exactly which AI is active.

How to Enable On-Device AI

Select On-Device AI in Settings, then download the model. The model remains on your device after installation.

1

Open App Settings

Tap the profile icon in the top-right corner of the home screen, then select Settings.

2

Navigate to AI Provider

Scroll to the AI section and tap AI Provider. You'll see the current selection: Cloud (default) or On-Device.

3

Select On-Device AI

Tap On-Device (Gemma). ListAIse will prompt you to download the model if it's not already on your device. Confirm to begin the download, which is approximately 3 to 4 GB.

4

Wait for Download

The model downloads in the background. You can continue using the app normally during this time. A progress indicator shows download status.

5

You're ready

Once downloaded, On-Device AI activates automatically. All subsequent AI requests process entirely on your device.

Wi-Fi recommended

The Gemma model is 3 to 4 GB. Download it over Wi-Fi to avoid using mobile data.

First-Run Warm-Up

The first time you use On-Device AI after launching the app, the model needs to load into memory. This is called the warm-up. It only happens once per app session.

First request may take up to 60 seconds

The warm-up is a one-time cost per session. After the model is loaded, every subsequent request is instant because there is no network round trip.

What you'll see during warm-up

1

Loading sheet appears

A modal sheet slides up showing "Preparing on-device AI…" with an indeterminate progress indicator. ListAIse is loading the Gemma model into memory.

2

Model ready

Once loaded, the sheet closes and your request processes immediately. The model stays warm for the rest of the session.

Proactive warm-up

ListAIse tries to warm up the model in the background when you open a list, before you even tap the microphone. This makes the first request feel instant in most cases.

On-Device Voice Transcription

On-Device AI includes a separate model for voice transcription: Whisper, running locally via a compact on-device implementation. This means your voice never leaves your phone, including for transcription.

Whisper On-Device

The Whisper model handles speech-to-text entirely on your device. Once installed, voice input works without an internet connection, including in stores with poor signal.

Setting up on-device voice

1

Tap the microphone icon

In any list, tap the microphone button to start voice input.

2

Install the voice model

If Whisper isn't installed yet, a sheet appears showing the model size and an Install button. Tap it to download.

3

Download completes

A progress bar shows the download. Once complete, voice input activates immediately. Future sessions use the already-installed model.

Model sizes

Whisper is available in multiple sizes (approximately 600 MB to 1.5 GB). Larger models offer better accuracy across accents and noisy environments. Choose based on your available storage and accuracy needs.

Privacy and offline use

On-Device AI keeps supported requests local and can run without a connection after the models are installed.

Local processing

Your grocery lists, voice recordings, and recipe content never leave your device. Third-party servers do not process this data.

Fully Offline

AI features work in supermarket basements, rural areas, parking garages, and anywhere with poor or no connectivity.

No network round trip

After the initial warm-up, requests are processed locally without waiting for a server response.

You're in Control

You decide which AI handles your data. Switch between Cloud and On-Device anytime from Settings. Your preference persists across sessions.

Device Requirements

On-Device AI runs large neural network models, so it requires available storage space and a modern device processor.

Model	Purpose	Size
Gemma 4	Recipe analysis, AI features	3.1 GB to 4.4 GB
Whisper	Voice transcription	About 600 MB to 1.5 GB

Storage tip

You don't need to install both models. Download Gemma for AI features or Whisper for voice input. Each model can be enabled or disabled independently.

Fallback Behavior

If On-Device AI encounters an error (model loading failed, not enough memory, etc.), ListAIse never silently falls back to cloud AI. You always stay in control.

When local AI fails, you choose

Use cloud this time processes this request through Cloud AI without changing your AI provider setting.
Cancel stops the request without sending the data.

Cloud fallback requires confirmation

ListAIse asks before sending a failed local request to Cloud AI. The fallback sheet lets you use the cloud for that request or cancel it.

Best Practices

Choose the mode that fits your connection, storage, and processing preference.

Use On-Device AI when…

• You're shopping in areas with poor connectivity
• You're privacy-conscious and don't want any data leaving your device
• You use voice input frequently and want offline transcription
• You want instant responses without network delays

Use Cloud AI when…

• Your device has limited storage (under 5 GB free)
• You're on a newer device that hasn't warmed up the model yet
• You want to conserve device RAM during heavy multitasking

First session tip

The model warm-up on first use can take up to 60 seconds. If you're in a hurry, open ListAIse a minute before you start shopping so the model loads in the background.
