# Welcome to StackAI

StackAI is an AI agent you run where you work. Tell it what you want — it reads your files, runs commands you approve, writes code, and pulls live on-chain data through **skills**. Use it in your terminal, on the web ([Vibe](/web/vibe.md)), or on [Telegram](/telegram/telegram.md).

```bash
npm install -g stackai
stackai login
stackai
```

{% hint style="success" %}
**Free to start** — 50 requests/day, no credit card. Sign in with X at [usestackai.com](https://usestackai.com) to grab a key.

### What makes it different

* **It does real work** — reads and writes the actual files in your project and runs commands you approve.
* **Skills, not hard-coding** — load a [skill](/skills/skills.md) for a task, or [install more](/skills/installing-skills.md) from any GitHub repo.
* **Multi-surface** — the same agent in your terminal, on the web, and on Telegram.
* **You stay in control** — bring your own model/keys ([Venice](/the-cli/models.md), [Bankr](/skills/bankr.md)); your trading key never leaves your machine.
* Powered by **Xiaomi MiMo v2.5 Pro** with a **1M token** context window.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.usestackai.com/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
