polyptych 0.2.0

Turn a source text into visual media — slide decks and single-page infographics, with multi-provider text and image generation

Polyptych Studio

Turn a source essay (markdown) into visual media. Polyptych Studio ships two fully independent pipelines — a slide deck generator and a single-page infographic generator — built on multi-provider text generation (Gemini, OpenAI, xAI, Anthropic, Vertex AI) and multi-provider image generation (Gemini, OpenAI, xAI, Vertex AI via pixbridge).

Full documentation — tutorial, how-to guides, reference, and architecture explanation.

Pipelines

Each pipeline takes a source essay (markdown) and produces a different kind of visual output.

Pipeline	Command	Output	Use case
Slide	polyptych deck	Presentation deck (10–30 slides with images)	Essay-to-slides conversion
Infographic	polyptych infographic	Single-page infographic(s), N variants	Quick visual summary of key data

Both run unattended end-to-end: the LLM text tasks (slide: task1→task7; infographic: i0→i2) run first, then image generation.

Both infographics above were generated by Polyptych Studio itself from examples/about-polyptych-studio.md using the infographic pipeline and the semi-flat-vector style.

Installation

Install the published package (the distribution and import name is polyptych; this repository is polyptych-studio):

pip install polyptych        # or: uv add polyptych

Or work from a clone of this repo:

uv sync

Optional external tool: ImageMagick (brew install imagemagick) for collecting a slide deck into a PDF via just create-pdf.

Environment variables

Set a key for each provider you intend to use (copy .envrc.example to .envrc, or export them however you manage secrets):

Provider	Environment variable
Gemini (text + image)	GOOGLE_API_KEY
OpenAI (text + gpt-image-2)	OPENAI_API_KEY
xAI / Grok	XAI_API_KEY
Anthropic Claude	ANTHROPIC_API_KEY
Vertex AI	Application Default Credentials (gcloud auth application-default login)

Quick start

An example source (examples/scene.md, a short noir scene) ships with the repo.

# Infographic (3 text tasks + images)
uv run polyptych infographic examples/scene.md -o generated/my-infographic

# Slide deck
uv run polyptych deck examples/scene.md -o generated/my-slides

With style presets

A few example visual-style presets ship under prompts/style-transfer/ (anime/, editorial/, infographic/, noir/, period-art/). Point --style at any preset markdown file, or author your own (see Write Style Prompts):

uv run polyptych deck examples/scene.md --style prompts/style-transfer/noir/cinematic-illustrative-noir.md
uv run polyptych infographic examples/scene.md --style prompts/style-transfer/infographic/semi-flat-vector.md

Presets, resume, and selective regeneration

# Reusable provider/size/quality bundles from image-presets.yaml
uv run polyptych deck examples/scene.md --image-preset openai-high

# Resume from image generation (text tasks already done)
uv run polyptych deck examples/scene.md -o generated/my-slides --from images

# Regenerate specific slides only
uv run polyptych deck examples/scene.md -o generated/my-slides --from images --slides 3,7,12

See the Resume Pipeline guide for details. Use just --list for all workflow shortcuts and the CLI Reference for the full flag set.

Operating modes

The system can be driven two ways:

• Python CLI — run polyptych directly (or via just targets). Best for scripts, CI, batch runs, and reproducible pipelines.
• Claude Code skills — inside a Claude Code session, type slash commands like /run-pipeline, /run-local-pipeline, /infographic, /review-regen, /edit-output. Best for exploration, guided iteration, and running text tasks with Claude as the LLM (zero API cost for text). The skill list is in CLAUDE.md.

Both surfaces share the same task templates, schemas, and output layout. See Operating Modes for the comparison.

Image generation is provided by the pixbridge PyPI package (pixbridge CLI), which supports Gemini, OpenAI, xAI, and Vertex.

Using Vertex AI

gcloud auth login
gcloud auth application-default login

Vertex AI uses Application Default Credentials. The vertex text and image providers use the same Gemini models but route through Google Cloud.

Continuous integration

.github/workflows/ci.yml runs on every pull request and on pushes to main, gating three checks (a failure in any fails the build):

Check	Command
Lint	uv run ruff check src/
Type check	uv run pyright src/
Unit tests	uv run pytest -m "not integration" tests/

Run the same locally with just lint, just typecheck, just test. Integration tests (@pytest.mark.integration) are excluded — they call real, paid LLM / image APIs. All dependencies (including pixbridge) resolve from PyPI, so CI needs no special access.
