React Native AI

A collection of on-device AI primitives for React Native with first-class Vercel AI SDK support. Run AI models directly on users' devices for privacy-preserving, low-latency inference without server costs.

Features

• 🚀 Instant AI - Use built-in system models immediately without downloads
• 🔒 Privacy-first - All processing happens on-device, data stays local
• 🎯 Vercel AI SDK compatible - Drop-in replacement with familiar APIs
• 🎨 Complete toolkit - Text generation, embeddings, transcription, speech synthesis

Available Providers

Apple

Native integration with Apple's on-device AI capabilities:

• Text Generation - Apple Foundation Models for chat and completion
• Embeddings - NLContextualEmbedding for 512-dimensional semantic vectors
• Transcription - SpeechAnalyzer for fast, accurate speech-to-text
• Speech Synthesis - AVSpeechSynthesizer for natural text-to-speech with system voices

Installation

npm install @react-native-ai/apple

No additional linking needed, works immediately on iOS devices (autolinked).

Usage

import { apple } from '@react-native-ai/apple'
import { 
  generateText,
  embed, 
  experimental_transcribe as transcribe, 
  experimental_generateSpeech as speech 
} from 'ai'

// Text generation with Apple Intelligence
const { text } = await generateText({
  model: apple(),
  prompt: 'Explain quantum computing'
})

// Generate embeddings
const { embedding } = await embed({
  model: apple.textEmbeddingModel(),
  value: 'Hello world'
})

// Transcribe audio
const { text } = await transcribe({
  model: apple.transcriptionModel(),
  audio: audioBuffer
})

// Text-to-speech
const { audio } = await speech({
  model: apple.speechModel(),
  text: 'Hello from Apple!'
})

Availability

Feature	iOS Version	Additional Requirements
Text Generation	iOS 26+	Apple Intelligence device
Embeddings	iOS 17+	-
Transcription	iOS 26+	-
Speech Synthesis	iOS 13+	iOS 17+ for Personal Voice

See the Apple documentation for detailed setup and usage guides.

MLC Engine (Work in Progress)

Run any open-source LLM locally using MLC's optimized runtime. Currently in development and not recommended for production use.

Installation

npm install @react-native-ai/mlc

Requires manual setup including installing the MLC CLI. See the setup guide.

Usage

import { getModel, prepareModel } from '@react-native-ai/mlc'
import { generateText } from 'ai'

// Download and prepare model
await prepareModel('Llama-3.2-3B-Instruct')

// Generate response with Llama via MLC engine
const { text } = await generateText({
  model: getModel('Llama-3.2-3B-Instruct'),
  prompt: 'Explain quantum computing'
})

Note

MLC support is experimental. Follow the setup guide for detailed installation instructions.

Google (Coming Soon)

Support for Google's on-device models is planned for future releases.
