Brand-first slide deck library. Full creative control, zero abstraction tax.
Project description
openslides
Brand-first AI slide deck generator. Point it at any website, get a pitch deck in that brand's exact colors, fonts, and style.
65+ curated brands. Real SVG logos. One command.
Quick Start
pip install openslides-ai
playwright install chromium
Generate a deck (LLM-powered)
export GEMINI_API_KEY=your-key
# Generate 5 slides for Stripe
openslides generate stripe.com "Payment infrastructure for the internet" -n 5
# Generate for any brand in the database
openslides generate airbnb.com "Community-powered hospitality platform" -n 3
openslides generate spotify.com "Audio streaming and discovery" -n 3
Output: pixel-perfect 1920x1080 PNGs in /tmp/<domain>-deck/.
Generate from Python
from openslides import Brand, generate, export
brand = Brand.from_domain("stripe.com")
slides = generate(brand, "Payment infrastructure for the internet", num_slides=5)
export(slides, "/tmp/stripe-deck/")
The generate() function:
- Picks a layout variant per slide type (hero, dashboard, terminal, CTA)
- Sends a detailed blueprint + brand context to Gemini Pro
- Post-processes: injects real SVG logo, grid pattern, ambient glow, layout CSS
- Fixes round numbers, banned patterns, readability issues automatically
Build manual slides
For full creative control, write HTML/CSS directly:
from openslides import Brand, export, base_html
brand = Brand.from_domain("stripe.com")
def slide_hero():
return f'''
{base_html(brand)}
<body style="background:{brand.background}; padding:80px;">
<h1 style="font-family:'{brand.font_headline}'; font-size:72px; color:{brand.text};">
The GDP of the internet runs on
<span style="color:{brand.primary};">7 lines</span> of code.
</h1>
</body></html>
'''
export([slide_hero()], "/tmp/stripe-deck/")
Brand Database
65+ curated brands with verified colors, fonts, and typography pairings:
from openslides import Brand
brand = Brand.from_domain("stripe.com")
print(brand.primary) # "#635bff"
print(brand.font_headline) # "Space Grotesk"
print(brand.logo_img(32)) # Real SVG logo at 32px
Brands with real SVG logos: Stripe, Anthropic, Airbnb, Spotify, Shopify.
All 65+ brands have curated color palettes and distinctive headline fonts (never generic Inter). Full list in brands.py.
