The AI that built it can change it

Your slides are an HTML file — code. The same agent that generated the deck can modify any part of it. Describe what you want changed in plain English. No editor. No HTML knowledge. No dragging boxes around.

What you can change

Content

Change the title on slide 2 to "Q1 Revenue Breakdown"
and update the stats to: Revenue $4.2M, Growth 34%, New Customers 847

Add or remove slides

Add a comparison table slide after slide 5 — our product vs Competitor A and B
Remove slide 8 — we're cutting the roadmap section

Rearrange

Move the team slide to the end, right before Q&A

Style, colors, fonts

Switch to a dark navy background, white text, orange accents
Change the accent color to #FF6B35 across all slides
Use Inter for body text and Playfair Display for headings

Layout and components

Replace the bullet list on slide 6 with flip cards —
front shows the feature name, back shows the benefit

One change at a time

Stack too many instructions in one prompt and they conflict. Change content first, then style, then layout. Each edit is one prompt — check the result in your browser, then ask for the next change.

What it looks like in practice

Generate: “10-slide product launch deck for a developer tools company.”

Edit 1: “Slide 3 says ‘coming soon’ — change it to ‘available now, v2.1 launched March 15’”

Edit 2: “Color scheme is too muted. Use electric green #9FFF24 as the accent.”

Edit 3: “Add a customer quote between slide 7 and 8. Quote: ‘Cut our deploy time from 45 minutes to 3 minutes.’ — Sarah K., Platform Lead at Acme Corp”

Edit 4: “Architecture diagram on slide 5 is missing the CDN layer. Add it between the load balancer and origin servers.”

Four prompts. You’d spend longer repositioning one text box in PowerPoint.

Batching changes

Every edit uses tokens — a fraction of what the original generation cost. If you have several changes ready, batch them:

Make these changes:
1. Slide 2: change subtitle to "Series B Metrics"
2. Slide 4: swap the bar chart for a line chart
3. Slide 7: remove the third bullet point
4. All slides: change the font to Space Grotesk

The file is also plain HTML — open it in any text editor for quick fixes if you prefer.

Get started

  1. Install the html-slides skill
  2. Generate a deck
  3. Ask the AI to change whatever isn’t right

To present, the HTMLSlides app adds dual-display mode, speaker notes, and a laser pointer.

Your presentations are code. Code is what AI edits best.
