The Propelr Carousel Builder — topic, angle picker, and live preview side by side

Carousels are the highest-engagement format. And the most time-consuming.

LinkedIn document and carousel posts drive 3–6× the engagement of plain text. But designing them in Canva takes hours: write the slides, find the template, swap colors, export, debug the PDF size. Most creators give up after one attempt.

  • LinkedIn document posts average ~6.6% engagement vs ~2% for text
  • Carousels keep readers swiping → high dwell time → algorithm reward
  • Canva-based carousels take 1–3 hours per post for a single creator
  • Inconsistent design across carousels weakens your visual brand

How it works

  1. 1

    Set your topic and angle

    Type a topic ("AI coding tools for founders") and a specific angle ("I want to challenge the idea that AI replaces developers"). The angle is the single biggest determinant of whether the carousel lands.

  2. 2

    Pick the content angle

    Choose Best Angle (AI picks), Contrarian Take, Practical Playbook, Data & Insights, or Mistakes & Lessons. The angle structures how the AI writes the slides.

    Set slides, theme, and name

    Pick 5–10 slides, choose Dark/Ocean/Light theme, add your name and handle. AI writes all slides, applies the theme, and exports a LinkedIn-ready PDF.

Capabilities

  • AI-written slides

    Each slide gets a tight headline + 1–3 supporting lines, structured per your chosen angle.

  • 5–10 slide range

    7 slides is the sweet spot for completion rate; 5 is punchier; 10 supports a full framework.

  • Three themes

    Dark, Ocean, or Light — picked to match the LinkedIn feed background and your brand tone.

  • PDF export

    LinkedIn-native document post format. Larger thumbnail in feed, swipeable on mobile, higher engagement than image carousels.

  • Voice-trained

    Slides use your Content DNA if set, so even the carousel sounds like you.

  • Edit before export

    Tweak any slide's text, change the order, or regenerate a single slide before downloading.

Who it's for

  • B2B founders teaching frameworks

    Carousels are perfect for breaking down a method into steps that build authority over time.

  • Anyone tired of Canva

    If you've abandoned a Canva carousel halfway through, this is the workflow that gets them shipped.

  • Creators chasing reach

    Document posts are the single biggest engagement-rate lever on LinkedIn in 2026. Hit publish, watch dwell time spike.

Frequently asked questions

How many slides should I use?

Seven slides is the sweet spot — enough to develop an idea, not so many that drop-off kills your completion rate. Use 5 for punchy lists, 8–10 for full frameworks.

Does it really export as a LinkedIn-native PDF?

Yes. The output is the PDF format LinkedIn renders inline as a swipeable document post, with a larger thumbnail and better engagement signals than image-based carousels.

Can I edit slides before exporting?

Yes. After the AI writes the slides, you can edit any text inline, regenerate a single slide, or reorder them before the PDF is generated.

What if I want a different design?

Three themes available today: Dark, Ocean, Light. Custom branding (your colors, your logo) is on the roadmap.
