Why it is worth attention

It enforces physical quality checks (contrast, overflow, fact-fidelity) and uses a self-healing factory runner for mass production, offering a free, self-hosted alternative to Canva bulk-create and Predis.ai.

Who it is for

Social media marketers and content creators
Developers building automated content pipelines
Small businesses or agencies needing branded carousels
Journalists and publishers repurposing news into posts

Use cases

Converting a news article into a ready-to-post Instagram carousel and Reels
Batch-generating brand-consistent carousels for a campaign
Automating social media content from a list of topics with minimal human effort
Producing fact-checked and WCAG-compliant visual stories

Strengths

Fully open-source, free, and self-hosted with no watermarks
Produces both carousel and Reels from the same copy, ensuring consistency
Hard quality gates (WCAG contrast, overflow, fact-fidelity) prevent broken output
Self-healing factory runner for parallel batch production with automatic retries

Considerations

Requires manual installation of Node.js 20+, Python 3.11+, and Chrome headless
Output limited to Instagram formats (4:5 carousel and 9:16 Reels) only
Fact-fidelity gate relies on external copywriting; may need human oversight for accuracy

English | 한국어

An open-source alternative to Canva bulk-create, Predis.ai, and Ocoya — but the output is measured against physical quality gates, not vibes.

Demo

Carousel (4:5)


Photo article (`newsprint`)	Numbered roundup (`newsprint`)	Photo feature (`newsprint`)

Hero above: the newsprint cover system — modeled on a 300K-like Instagram carousel.

Reels (9:16)

https://github.com/kimsh-1/cardprinter/raw/main/docs/demo-reel.mp4

Every carousel is derived from the same copy contract as its Reels cut, so the two never drift apart. (The clip above is a real pipeline output; GitHub renders docs/demo-reel.mp4 inline.)

✨ Features

🗞️ One-line input — give it a topic (or a news article); it writes the copy, lays out the cards, and renders both formats.
🎨 Tone tiers — luxury · character · brand · news · editorial · data, plus custom tiers auto-built from a company's BI deck or a 5-question interview.
📐 Viral sequence templates — checklist · listicle · data-infographic · photo-story · storytelling · versus, each a research-backed slide flow (triple-hook, mid save-trigger, end CTA).
🛡️ Physical quality gates — contrast (WCAG pixel-measured), overflow (bbox ⊂ safe zone), fact-fidelity (no fabricated numbers), typography floor, layout diversity — all exit-code hard gates, not suggestions.
📊 Honest charts — echarts SSR bar charts with a 0-based scale; the display string is the source of truth so numbers can't be exaggerated.
🎬 Card-news → Reels — finished cards are composited into a 1080×1920 timeline with clean rise-in transitions (list/chart items reveal one by one — no zoom, no jitter), silent kinetic captions, per-card dwell derived from reading speed.
🏭 Mass production — a headless codex factory runner produces topics in parallel with a self-heal loop (failed gates are fed back and regenerated).

Why this instead of Canva / Predis.ai?
