ZeroChat

ZeroChat es un cliente web de uso personal para conversar con modelos de IA, consultar documentos y utilizar herramientas. Esta documentación corresponde a la serie 8.x, que consolida las funcionalidades existentes. El desarrollo de nuevas funcionalidades queda en pausa por el momento.

La interfaz se sirve como archivos estáticos: zerochat.html necesita sus módulos js/ y css/. El historial y la configuración se guardan en el navegador; no se sincronizan automáticamente entre dispositivos. Los proveedores remotos reciben el contenido incluido en las peticiones, y las herramientas web pueden utilizar servicios intermediarios. Almacenamiento local no significa privacidad absoluta.

English: ZeroChat is a web client for personal use: chatting with AI models, consulting documents and using tools. This documentation covers the 8.x series, which consolidates existing features. New feature development is paused for now.

The interface is served as static files: zerochat.html needs its js/ and css/ modules. History and settings are stored in the browser, without automatic cross-device sync. Remote providers receive content included in requests, and web tools may use intermediary services. Local storage does not mean absolute privacy.

Características principales / Main features

  • Perfiles: OpenAI y APIs de chat compatibles, Ollama, OpenRouter, Claude y Gemini. La visión, las herramientas y el razonamiento dependen del modelo y del adaptador.
  • WebLLM: inferencia en el navegador con WebGPU, tras descargar un modelo. Necesita hardware compatible y memoria suficiente.
  • Documentos: adjuntos y colecciones RAG con extracción local y búsqueda léxica mediante Orama; sin embeddings. Los fragmentos recuperados se envían al modelo elegido. La extracción de PDF tiene límites y no incluye OCR general.
  • Herramientas: JavaScript aislado, búsqueda y lectura web, gráficos, planes y puntos de control. El backend opcional añade archivos, comandos, diagnósticos, automatización de navegador y servicios MCP.
  • Historial y diagnóstico: ramas de conversación, exportación JSON y Markdown, impresión a PDF, métricas de contexto y revisión de peticiones antes del envío.

English:

  • Profiles: OpenAI and compatible chat APIs, Ollama, OpenRouter, Claude and Gemini. Vision, tools and reasoning depend on the model and adapter.
  • WebLLM: browser inference through WebGPU after downloading a model. Requires compatible hardware and enough memory.
  • Documents: attachments and RAG collections with local extraction and Orama lexical search, without embeddings. Retrieved passages are sent to the selected model. PDF extraction has limitations and no general OCR.
  • Tools: isolated JavaScript, web search and retrieval, charts, plans and checkpoints. The optional backend adds files, commands, diagnostics, browser automation and MCP services.
  • History and diagnostics: conversation branches, JSON and Markdown export, printing to PDF, context metrics and request inspection before sending.

Inicio rápido / Quick start

Abre ZeroChat en GitHub Pages, crea un perfil, introduce la URL y la clave si corresponde, consulta los modelos con Query y guarda. El perfil Espejo permite probar la interfaz sin inferencia. Para WebLLM, prepara un modelo del catálogo.

English: Open ZeroChat on GitHub Pages, create a profile, enter the URL and key where required, query models with Query, and save. Mirror lets you try the interface without inference. For WebLLM, prepare a catalogue model.

Para añadir herramientas del equipo, instala y ejecuta el backend con Python. / To add computer tools, install and run the Python backend:

# Linux, macOS, Android (Termux)
pip install zerochat
zerochat
# Windows (PowerShell o CMD / PowerShell or CMD)
py -m pip install zerochat
py -m zerochat

También puedes descargar el script y ejecutarlo. / You can also download and run the script:

# Linux, macOS, Android (Termux)
curl -fsSL https://albalday.github.io/zerochat/zerochat.py -o zerochat.py
python3 zerochat.py
# Windows (PowerShell o CMD / PowerShell or CMD)
curl.exe -fsSL https://albalday.github.io/zerochat/zerochat.py -o zerochat.py
py zerochat.py

Entornos probados / Tested environments: Linux (x86_64, ARM), Windows 10/11 (PowerShell, py -m zerochat), Android (Termux con python; Playwright no se puede usar actualmente en Termux / Playwright cannot currently be used on Termux).
Navegadores / Browsers: ZeroChat no es compatible con Safari / does not work on Safari. En macOS debería funcionar con Firefox o Chromium, pero no se ha probado / On macOS it should work with Firefox or Chromium, but it has not been tested.

Fuera del repositorio de desarrollo, ambos modos abren la interfaz de GitHub Pages. Crean ~/zerochat/ para configuración y servicios, con .venv/ para dependencias MCP Python. Mantén el proceso abierto y usa su enlace de arranque para autenticar la conexión local. Revisa Ajustes → MCP y Permisos antes de habilitar herramientas: los comandos actúan con los permisos del proceso local y detenerlos no deshace cambios.

Borrar ~/zerochat/ elimina ese estado y los MCP gestionados, no el ejecutable, los archivos modificados fuera de esa carpeta ni los datos del navegador. Exporta las conversaciones y perfiles que quieras conservar; sus copias no incluyen las colecciones RAG ni los modelos descargados. El cifrado predeterminado de perfiles utiliza una clave integrada conocida: trata las copias como archivos sensibles.

English: Outside the development repository, both modes open the GitHub Pages interface. They create ~/zerochat/ for configuration and services, with .venv/ for Python MCP dependencies. Keep the process running and use its startup link to authenticate the local connection. Review Settings → MCP and Permissions before enabling tools: commands run with the local process permissions, and stopping them does not undo changes.

Deleting ~/zerochat/ removes that state and managed MCP services, not the executable, files changed elsewhere or browser data. Export conversations and profiles you want to keep; these backups do not include RAG collections or downloaded models. Default profile encryption uses a known built-in key: treat backups as sensitive files.

Desarrollo / Development

Trabaja en dev. Para instalar dependencias y ejecutar las pruebas del proyecto: / Work on dev. To install dependencies and run the project tests:

npm install
npm test

Dentro del repositorio, python3 zerochat.py sirve la interfaz local de desarrollo. Si modificas py/, reconstruye zerochat.py con npm run build:backend. La web carga directamente sus módulos, sin un bundle de aplicación.

English: Inside the repository, python3 zerochat.py serves the local development interface. After changing py/, rebuild zerochat.py with npm run build:backend. The web app loads its modules directly, without an application bundle.

Las normas y validaciones se describen en AGENTS.md y tests/README.md.
