1
Prepare Your AI-Generated HTML File
Before using Slidum, ensure your source material is ready. Most AI presentation tools (like Marp, Slidev, or custom LLM prompts) output standard HTML files with embedded CSS or JavaScript. Slidum is designed specifically to interpret these HTML-based presentation structures. Open your generated `.html` file in a text editor to verify it contains valid HTML5 structure. Check for relative paths to images or assets; Slidum works best when assets are either embedded as Base64 data URIs or hosted on publicly accessible URLs. If your AI tool generated a `.md` (Markdown) file, convert it to HTML first using a tool like Pandoc or a simple Markdown-to-HTML converter, as Slidum expects HTML input. Ensure the `<head>` section includes any necessary meta tags for viewport scaling, as Slidum will render the content based on these definitions.
Pro Tip
Always backup your original AI output before modifying it. If your presentation relies on external CSS files, consider inlining them to avoid CORS errors during rendering.

Upload Your Presentation to Slidum
Navigate to https://slidum.com in your web browser. The interface is designed for simplicity, featuring a prominent upload area. Click the 'Upload' button or drag and drop your prepared HTML file directly into the designated zone. Slidum accepts standard HTML files. Upon upload, the system begins parsing the document. This process is near-instantaneous for most standard presentations. You will see a progress indicator as Slidum analyzes the DOM structure, identifies slide boundaries (often defined by data attributes like `data-slide` or specific class names), and prepares the rendering engine. If the file is corrupted or lacks proper HTML structure, Slidum will display a validation error. In such cases, return to your source file to check for unclosed tags or malformed JSON data within scripts.
Pro Tip
For large presentations with many slides, ensure you have a stable internet connection. Slidum processes the file in the cloud, so upload speed may affect initial load times.
3
Review and Adjust Rendering Settings
Once uploaded, Slidum generates a preview of your presentation. This is the core value proposition: seeing how your AI-generated code translates to a visual deck. Use the preview pane to scroll through your slides. Pay close attention to font rendering, image alignment, and responsive behavior. Slidum allows you to tweak basic display settings. You can adjust the background color, change the default font family if the AI used obscure web fonts that aren't loading, and modify the aspect ratio (e.g., 16:9 for modern displays or 4:3 for legacy projectors). If a slide looks broken, use the 'Inspect' feature to view the raw HTML structure Slidum is interpreting. This helps you identify if the AI generated invalid CSS classes. You can make quick inline edits directly in the Slidum editor if minor fixes are needed without downloading and re-uploading.
Pro Tip
Use the 'Fullscreen Preview' mode to simulate the actual presentation experience. This helps catch issues with text readability and contrast that might be missed in the editor view.

Optimize for Performance and Compatibility
Before finalizing, consider the performance of your slides. AI-generated HTML can sometimes be bloated with unnecessary code. Slidum’s engine is optimized for speed, but heavy JavaScript animations or high-resolution uncompressed images can cause lag. Use Slidum’s optimization suggestions if available. The tool may flag images that are too large or scripts that are blocking rendering. You can choose to strip non-essential scripts to ensure a smooth playback experience. Additionally, check for accessibility features. Slidum can automatically add ARIA labels to slide elements if your HTML is semantic. This is crucial for professional environments where accessibility standards are required. Review the navigation controls to ensure keyboard shortcuts (like Arrow keys for next/previous slide) are functioning correctly. This step ensures your presentation is not just visually appealing but also robust and user-friendly.
Pro Tip
If your presentation includes interactive elements like charts or graphs, test them thoroughly. Slidum supports standard web interactions, but complex third-party libraries might require specific API keys or configurations.
5
Export and Share Your Presentation
When you are satisfied with the preview, it’s time to export. Slidum offers multiple output formats. The primary format is a shareable web link, which is ideal for quick sharing with colleagues or clients who just need to view the slides in a browser. This link serves the rendered HTML directly from Slidum’s servers, ensuring consistent appearance across devices. For offline use or integration into other workflows, you can export as a PDF. This converts each slide into a high-quality PDF page, preserving fonts and images. You can also export the final HTML bundle if you need to host it on your own server. Click the 'Export' button, select your desired format, and download the file. The PDF export is particularly useful for printing or archiving. The web link is best for real-time collaboration and viewing on mobile devices.
Pro Tip
When sharing via link, consider setting an expiration date if the content is sensitive. Slidum’s share links are public by default, so use caution with confidential information.

Integrate Slidum into Your AI Workflow
To maximize efficiency, integrate Slidum into your automated AI workflow. If you are using an LLM to generate presentations, configure your prompt to output clean, semantic HTML with consistent class names. For example, instruct the AI to use `class="slide"` for each slide container. This consistency makes Slidum’s parsing more reliable. You can also use Slidum’s API (if available for enterprise users) to automate the rendering process. By sending the HTML content via a POST request to Slidum’s endpoint, you can automatically generate shareable links or PDFs without manual intervention. This is particularly powerful for developers building internal tools that generate reports or pitches on the fly. Document your preferred HTML structure and stick to it across all AI-generated content to reduce manual tweaking time in Slidum.
Pro Tip
Create a template HTML file that you feed into your AI prompts. This ensures the output structure is always compatible with Slidum, reducing errors and saving time.
