AI-powered content framework for Streamlit — create presentations, courses, and web-books with Claude or Cursor, no coding required.

StreamTeX

AI-powered content framework for Streamlit — create presentations, courses, and web-books with Claude or Cursor. No coding required.

StreamTeX combines a modular block architecture with AI-powered workflows. Describe your project in natural language, and let Claude or Cursor build it — or use the Python API for full control.

Getting Started

StreamTeX supports 4 installation levels. Pick the one that fits your needs.

Quick Start (minimal, no workspace)

From zero to a running project in 3 commands:

uv tool install "streamtex[cli]" -U
stx project new my-project
cd my-project && uv sync && stx run

Standard Setup (recommended)

Full workspace with rich templates, documentation, and Claude AI profiles:

uv tool install "streamtex[cli]" -U
mkdir streamtex-dev && cd streamtex-dev
stx install
stx update
stx project new my-project --template project   # CLI templates: project, collection, slides
cd projects/my-project
stx claude install project .
stx run

Full Setup (all optional features)

Everything above, plus AI image generation, PDF export, and live inspector:

uv tool install "streamtex[cli]" -U
mkdir streamtex-dev && cd streamtex-dev
stx install --preset power --project my-project --template project
stx update
cd projects/my-project
stx run

The power preset automatically installs PDF export, AI image generation, and the live inspector into your project. To add Playwright for PDF export, run:

uv run playwright install chromium

Each uv add installs optional features into the current project's environment. Pick only what you need — or install individual AI providers:

uv add "streamtex[ai-openai]"    # OpenAI only
uv add "streamtex[ai-google]"    # Google Imagen only
uv add "streamtex[ai-fal]"       # fal.ai only

AI image generation requires API keys in your .env file: STX_OPENAI_API_KEY, STX_GOOGLE_AI_KEY, STX_FAL_KEY (only the providers you use). See the AI Guide for configuration details.

Prerequisites: Python 3.11+, git, uv.

Zero-Code with Claude or Cursor

Install StreamTeX and a Claude AI profile, then let the AI build your project:

uv tool install "streamtex[cli]" -U
mkdir streamtex-dev && cd streamtex-dev
stx install && stx update
stx project new my-project
cd projects/my-project
stx claude install project .

Open in Claude Code or Cursor, then use slash commands:

/stx-project:project-init
> "Create a Docker course with 12 slides, dark theme,
>  table of contents and page navigation"

The AI agent designs the project structure, proposes it for your approval, and generates all files — blocks, styles, book.py — ready to run:

stx run

See the AI Guide for all commands, agents, and workflows.

Code-First with Python

import streamlit as st
import streamtex as sx
from streamtex.styles.core import Style

st.set_page_config(page_title="My Book", layout="wide")

style = Style("color: navy; font-size: 1.2em;", "my-style")
sx.st_write(style, "Hello StreamTeX!")

stx run app.py

Manual Installation (without stx CLI)

pip install streamtex
git clone https://github.com/nicolasguelfi/streamtex-claude.git
mkdir my-project && cd my-project
python ../streamtex-claude/install.py project .
stx run

Workspace Presets

The stx install command supports 5 presets:

Preset	Repos	Extras (with --project)	Use case
basic	none	pdf	Workspace only, upgrade later
user	streamtex-claude	pdf	+ Claude AI profiles
standard (default)	streamtex-docs + streamtex-claude	pdf, ai	+ rich templates + local docs
power	streamtex-docs + streamtex-claude	pdf, ai, inspector	+ all extras, requires --project
developer	all 3 repos	pdf, ai, inspector	+ library source + editable install

stx install --preset user       # Claude profiles only
stx install                     # standard (default)
stx install --preset developer  # full developer setup
stx install --preset power --project my-project  # all extras with a project

Upgrade an existing workspace to a higher preset:

stx install --preset developer
stx update

Optional Extras

StreamTeX uses optional dependency groups so you install only what you need:

uv add "streamtex[ai]"           # AI image generation (OpenAI + Google Imagen + fal.ai)
uv add "streamtex[ai-openai]"    # AI images — OpenAI only
uv add "streamtex[ai-google]"    # AI images — Google Imagen only
uv add "streamtex[ai-fal]"       # AI images — fal.ai only
uv add "streamtex[pdf]"          # PDF export via Playwright
uv add "streamtex[inspector]"    # Live code inspector sidebar
uv add "streamtex[cli]"          # stx CLI (already installed as a global tool above)

See the AI Image Generation section in the AI Guide for configuration and usage.

Installation

# Install or upgrade the CLI as a global tool
uv tool install "streamtex[cli]" -U

# Or as a project dependency
uv add streamtex

Optional extras:

uv add "streamtex[cli]"          # stx CLI commands
uv add "streamtex[inspector]"    # Live code inspector sidebar
uv add "streamtex[ai]"           # AI image generation (OpenAI + Google Imagen + fal.ai)
uv add "streamtex[ai-openai]"    # AI images — OpenAI only
uv add "streamtex[ai-google]"    # AI images — Google Imagen only
uv add "streamtex[ai-fal]"       # AI images — fal.ai only
uv add "streamtex[pdf]"          # PDF export via Playwright

Prerequisites

• Python >= 3.11
• uv (recommended package manager)
• git

Project Configuration

StreamTeX projects using from streamtex import * require this ruff config in pyproject.toml (automatically generated by stx project new):

[tool.ruff.lint]
ignore = ["F403", "F405", "E701", "E741"]

If your project uses [tool.uv.sources] for editable installs, set UV_NO_SOURCES=1 in CI environments so uv resolves from PyPI instead of local paths.

Keeping Up to Date

Update the CLI

The stx CLI is installed as a global tool with its own frozen copy of the library. You must upgrade it explicitly after each release:

uv tool install "streamtex[cli]" -U

Update your workspace

cd streamtex-dev/
stx update                   # pulls repos, syncs deps, updates profiles

Fine-grained control:

stx update --skip-sync      # skip uv sync
stx update --skip-profiles  # skip Claude profile update

Check workspace status

stx status                   # show preset, repos, profiles, project list

Upgrade a project

stx project upgrade          # upgrade project deps and extras to match current preset

Update a standalone project (no workspace)

cd my-project/
uv add streamtex --upgrade   # update the library dependency

Use /stx-guide update inside Claude Code for guided assistance.
