In this article, you will learn how to build multimodal AI capabilities — image classification, image captioning, and speech transcription — that run entirely in the browser using Transformers.js, with no server, no API key, and no data leaving the user’s device.
Topics we will cover include:
How to set up and run image classification and image captioning pipelines using Vision Transformer models in the browser.
How to implement browser-based speech transcription using OpenAI’s Whisper architecture via the Web Audio API.
How to combine all three pipelines into a single multimodal media analyzer that loads models in parallel and presents results in a unified dashboard.
