The Problem

PowerPoint is 37 years old.
It shows.

Built in 1987 for a world without the internet, AI, or CSS. Yet here we are, still dragging text boxes in 2025.

📦
.pptx is a zip file full of XML
Open a .pptx in a text editor. Go ahead. It's like reading assembly code written by a committee in 1999.
💸
$300/year to make bullet points
Microsoft 365 charges you monthly to use software that looks the same as it did in Office 2003. The animations still suck.
🖱️
You spend hours on layout, not ideas
Pixel-pushing text boxes. Aligning shapes manually. Fighting with "SmartArt." This is not how great ideas should be communicated.
💔
Every device renders it differently
Looks perfect on your Mac. Explodes on the conference room PC. Fonts missing. Slides shifted. Presenter embarrassed. Classic.
🔒
You can't version control a .pptx
"FinalFinal_v3_ACTUALLY_FINAL.pptx" isn't version control. Your slides should live in git like everything else that matters.
🐢
AI can't help with PowerPoint
Ask Claude to design a slide. Watch it struggle. Now ask it to write HTML. Watch it thrive. One of these is the future.
The Alternative

HTML is the best
slide format ever made.

Every capability you want already exists — CSS animations, custom fonts, SVG charts, embeds. AI knows HTML perfectly.

📊
PowerPoint / Keynote
  • Proprietary binary format, impossible to diff
  • AI assistance is clunky and limited
  • Pay $300+/year forever
  • Breaks across machines and OS versions
  • Layout tools from 1995
  • Can't use JavaScript or CSS animations
  • Sharing means emailing files like it's 2003
  • Presenter notes hidden, remote clunky
⚡
