Build a pitch deck

Create a polished, investor-ready pitch deck from scratch in under 10 minutes — no design skills needed.

Presenting and sharing your deck

Step 1: Go to the playground

Open /try.html

Visit /try.html and you'll see several quick-start "Try:" example chips below the prompt box. Look for the one that says "📊 Pitch deck".

Step 2: Launch with a template

Click the pitch deck chip

Click "📊 Pitch deck" and the prompt will auto-fill the text box with a pre-written prompt that asks for a 6-slide investor deck. This is a proven structure that works every time.

Or, if you prefer to write your own, use a prompt like:

Build a single-file HTML pitch deck for my company [Company Name]. 6 slides covering: problem, solution, market size, business model, team, and ask. Professional dark theme, bold typography, single accent color.

Step 3: Customize the prompt (optional)

Edit the prompt to match your business

Replace the fictional company name in the prompt with yours. Add specific details about what you do:

Instead of "an AI-native developer tool," specify: "an AI-powered customer support platform"
Mention your target market: "B2B SaaS for healthcare providers"
Include a tagline or mission: "Making healthcare support smarter and faster"

The more specific you are, the better the deck will be tailored to your business.

Pro tip: If you know your actual numbers (revenue, users, growth %), include them in the prompt. The AI will weave them into the slides naturally.

Step 4: Generate and preview

Click "Send" and watch it render

Select your preferred AI provider (LingModel is free, or use Claude/DeepSeek if you've set up keys) and click "Send". The AI will generate a complete 6-slide deck that appears instantly in the preview pane.

Step 5: Refine and iterate

Ask for changes using "Continue"

Once the deck is generated, use the "Continue" button to request specific tweaks:

"Make the title slide more dramatic"
"Add a revenue projection slide"
"Switch to a light theme"
"Make the accent color teal instead of blue"
"Add our company logo to the top of each slide"

Each request builds on the previous output — no need to start over.

Understanding the slide structure

LingCode uses a special HTML structure for pitch decks. Each slide is wrapped in <section class="slide"> with specific dimensions:

<section class="slide" style="width:1280px;height:720px;...></section>

This 16:9 aspect ratio is standard for presentations. When you export as PowerPoint (see step 6), each <section.slide> becomes one slide automatically.

Good to know: If you manually edit the deck code and add more <section class="slide"> elements, they'll all export as separate PowerPoint slides.

Step 6: Export as PowerPoint or PDF

Download your deck

In the preview pane, click the three-dots menu and choose:

Export PPT — Creates a .pptx file. Each <section.slide> becomes one PowerPoint slide. Open in PowerPoint, Google Slides, or Keynote to add notes, animations, or final touches.
Download .html — Get the raw HTML. Share as a link or embed in your website.
Export PDF — A PDF snapshot of all slides. Good for printing or sharing with investors who don't use PowerPoint.

Step 7: Present or share

Use your deck

If you exported as PowerPoint: Open in PowerPoint or Google Slides, add speaker notes, transitions, and animations, then present from there.

If you kept the HTML: Present directly in the browser using full-screen mode (F11) or share the link with investors.

If you exported as PDF: Share via email or upload to a document sharing service.

Pro tips

Data > hype: Real numbers (growth %, revenue, user count) are more persuasive than generic claims. Include them if you have them.
One accent color: Stick to one color (blue, green, purple) for visual cohesion. Ask the AI to use a consistent accent color across all slides.
Visual hierarchy: Make your headlines big (40-60px) and body text readable (14-18px). Good slides are scannable.
Test with an investor: Send your deck to a trusted advisor and ask for feedback before a real pitch. Iterate if needed.
Keep slide notes private: If you export as PowerPoint, add speaker notes (visible only in presenter mode) rather than on the slide itself.
