Run AI Models in the Browser and on Phones

Willow is a self-hosted voice assistant platform for people who want home automation voice control on their own hardware. It runs on Espressif's ESP32-S3-BOX family and connects to Home Assistant, openHAB, or other services that accept speech results over HTTP. The project is open source under Apache 2.0.

Maid is an Android AI chat app for people who want to run models on their phone and access remote models in the same app. It runs GGUF models locally through llama.cpp without an internet connection. It's open source under the MIT license, with no ads or telemetry.

ONNX Runtime is an open source inference and training engine for developers building AI into apps and services. It runs ONNX models across desktop systems, mobile devices, web browsers and servers. It's a fit when you need the same model format to work in several places, including on a user's device.

Transformers.js is a JavaScript library for developers building web apps that run AI models on the user's device. Inference happens in the browser, so an app doesn't need a separate model server to process its inputs. The library is open source under Apache 2.0.

PocketPal AI is an open source assistant for people who want to run language models on a phone or tablet. It works on iOS, iPadOS and Android. Once you've downloaded a model, you can chat offline without an account, and your prompts, replies and documents stay on your device. The app is licensed under MIT.

Draw Things is an AI image generation app for iPhone, iPad and Mac that keeps generation on your device and works offline. It's for people who want to create and edit images without sending that work to a cloud service, including artists developing character concepts or trying out apparel designs.

MLC LLM is an open-source compiler and deployment engine for developers who want to run language models on their own hardware or inside apps. Its main distinction is the range of devices it targets: the same underlying engine, MLCEngine, serves desktop, browser and mobile deployments. The project uses the Apache 2.0 license.

ChatterUI is an Android chat app for people who want to run a local LLM on their phone or use the same interface with a remote model. It supports assistant conversations and character chats, with controls for how chats are structured and how models generate replies. It's open source under AGPL-3.0.

TranslateLocally is an open source machine translation app for Windows, macOS and Linux. It's for people who want to translate text on their own device, including those handling material they don't want to send to a remote translation service. The desktop app has an MIT license and uses Marian and Bergamot translation models.

OpenVINO is an Apache 2.0 licensed toolkit for developers who want to run AI models locally or serve them on their own infrastructure. It converts and optimizes models for inference, with support for x86 and ARM CPUs, Intel integrated and discrete GPUs, and Intel NPUs. Its runtime works on Linux, Windows and macOS.

WebLLM runs language models directly in a user's browser, using WebGPU for GPU acceleration. It's an open-source engine for developers building web-based AI assistants and Chrome extensions that process prompts on the user's device rather than an inference server. The project uses the Apache 2.0 license.

Candle is a Rust machine learning framework for developers who want to embed local AI in applications or deploy models on their own servers. It produces lightweight binaries that don't need Python in production, making it a candidate for serverless inference where a large runtime can slow startup. Its API uses tensor operations familiar to PyTorch developers.

Google AI Edge Gallery is an open-source app for people who want to try generative AI on their own phone. It runs model inference locally, so offline chat, image analysis and audio tasks don't send your inputs to a server. It supports Android and iOS and uses the Apache 2.0 license.

Liquid Apollo is an AI chat app for iPhone and iPad. Liquid LEAP runs smaller language models directly on your device, so local conversations do not depend on a cloud service. The app also runs on compatible Apple Silicon Macs.

Google AI Edge Eloquent is an AI dictation app for iPhone and iPad that turns spoken thoughts into edited text using on-device Gemma models. It's for people who prefer speaking to typing but don't want every hesitation or self-correction carried into their notes and drafts.
