Chat, right away

Open elffuss.com and ask. A model running in your browser answers, on your own device, and what you type does not leave it. The first answer needs a one-time download of the model; after that it is ready every time you come back.

Or go straight to an app: Claw · Code · Translator · Copilot · Tools · Braid · All apps

How it works, in three steps

1. Open an app in Chrome or Edge. Nothing to install.
2. The first time, your browser downloads the model it needs and keeps it. After that it is not downloaded again.
3. Use it. Your voice, your files and your photos are processed in your browser tab, on your own graphics card.

Claw: ask for an app, and it appears

An agent that lives in your browser. You describe what you need, such as a mortgage calculator or a weekly plan, and it builds the app on the spot, next to the chat. It remembers what you tell it, sets reminders and keeps your secrets encrypted.

Code: an editor with an agent beside it

Open a folder of your project and work. The agent reads your code, explains it and changes it, in the style of VS Code, all in the tab.

Open Code →

Translator: a conversation, in two languages

Two people, two languages, one microphone. It translates by voice in real time and tells who is speaking. You can also paste a text. Offline once the models are downloaded.

Open Translator →

Copilot: skills for your meetings

It listens to your call and fills in the customer record as you talk. The audio never leaves your device; the record goes where you say, only when you press «Send».

Small tools

Cutout removes the background of a photo · Detect finds objects, even live from your camera · Depth turns a photo into a depth map you can turn in 3D · OCR reads text from images and PDFs, even whole folders · All tools

These are real results of the live tools, on public-domain photos.

For building with agents

• Braid: version control for AI coding agents. Many agents work in parallel and land on one main branch, with no bottleneck. Git and GitHub keep working.
• BraidHub: a hosted place where people and agents share Braid repositories.

The engine

elffuss-engine is our own runtime for the browser, written from scratch as WebGPU shaders. It loads standard GGUF models over HTTP and powers the advanced options in Claw and Code.

Open source

Chatea ya: abre elffuss.com y pregunta. Te contesta un modelo que corre en tu navegador, en tu propio dispositivo, y lo que escribes no sale de él. La primera respuesta necesita descargar el modelo una sola vez. Abrir el chat → · Todas las apps

Elffuss son apps de IA gratuitas que corren en tu navegador, en tu propia tarjeta gráfica: sin cuenta y sin clave de API. El modelo se ejecuta en tu dispositivo.

Cómo funciona: abres una app, la primera vez el navegador descarga el modelo y lo guarda, y desde ahí tu voz, tus archivos y tus fotos se procesan en la pestaña.

Claw crea apps pequeñas desde un chat · Code es un editor con agente · Translator traduce conversaciones y textos · Copiloto son skills para tus reuniones que rellenan la ficha del cliente mientras hablas · Braid es git sin cuellos de botella para agentes · y cuatro herramientas pequeñas: recortar fondo, leer texto, detectar objetos y profundidad.
