# Plan de acción > Estructura tus tareas Plan de acción is an installable web application (PWA) that shows an action plan as a diagram, like a metro map: every line is an area or macro task with its own colour, goal and priority, lines are grouped in tabs by topic, and every step (task, wait, decision, milestone, document, uncertainty) is connected to the steps it depends on. Each user has their own plan, edited on the site (diagram or board) or uploaded as a YAML file (tasks.yaml); progress is saved in a database and synchronized between the user's devices. The interface is available in Spanish (Spain, Mexico, Argentina, Chile), English (Canada, India), French (Canada, France), Portuguese (Brazil, Portugal), Italian and Hindi. ## Documentation - [Extended description](https://plan.ljg.cl/llms-full.txt): features, the tasks.yaml format, identifiers, and how to ask an assistant to create or change a plan. ## Notes - The content of every plan is private: it requires signing in. The API (/api/) is not public. - To create or change a plan with an AI assistant, the app builds a Word document in the user's language (Settings → Plan → Assistant prompts).
