Web AI Toolkit

The Web AI Toolkit simplifies the integration of AI features, such as OCR, speech-to-text, text summarization and more into your application. It ensures data privacy and offline capability by running all AI workloads locally, leveraging WebNN when available, with a fallback to WebGPU.

Installation

To install the Web AI Toolkit, run:

npm install web-ai-toolkit

Available Functions

Note: Supported hardware is listed in priority of device selection. For example, for transcribing an audio file, the code will attempt to choose an NPU first, then a GPU and finally the CPU if neither of the first two are found.

Technical Details

The Web AI Toolkit utilizes the transformers.js project to run AI workloads. All AI processing is performed locally on the device, ensuring data privacy and reducing latency. AI workloads are run using the WebNN API when available, otherwise falling back to the WebGPU API. Both of these APIs are used to "hardware accelerate" the AI inferences, with WebNN targeting NPUs and GPUs, and WebGPU strictly targeting GPUs.

Usage

Here are examples of how to use each function:

Transcribe Audio File

import { transcribeAudioFile } from 'web-ai-toolkit';

const audioFile = ...; // Your audio file Blob
const transcription = await transcribeAudioFile(audioFile, "Xenova/whisper-tiny", true, "en-US");
console.log(transcription);

Text to Speech

import { textToSpeech } from 'web-ai-toolkit';

const text = "Hello, world!";
const audio = await textToSpeech(text);
console.log(audio);

Summarize Text

import { summarize } from 'web-ai-toolkit';

const text = "Long text to be summarized...";
const summary = await summarize(text);
console.log(summary);

Optical Character Recognition (OCR)

import { ocr } from 'web-ai-toolkit';

const image = ...; // Your image Blob
const text = await ocr(image);
console.log(text);
