Blazon for Technical Presentations and Training

I recently switched to using Blazon for all my presentations, and I couldn't be happier. Here are some of my favorite features:

  • Markdown
  • Code block syntax highlighting
  • Shared code blocks
  • Line-by-line highlighting
  • Offline viewing

Effortless editing with markdown

Markdown is a plain-text formatting syntax that gets converted to HTML. The rules are simple and easy to pick up. As you type content for a slide, Blazon gives you a live preview of how that content is presented on a slide.


Syntax highlighting

Syntax highlighting makes code easier to read, and it's something that developers can appreciate.

Shared code blocks

Need to walk through a lot of code across multiple slides? Blazon let's you create and reference shared files. You can even select which lines from a file you want to appear on a slide. Make a change to a file, and all the slides that make use of that file are automatically updated. Boom.

Highlight specific lines of code

Blazon takes shared code files a step further by allowing you to highlight specific lines of code. This is a killer way to walk through your code.

No WiFi? No problem.

Blazon allows you to download your entire presentation as a self-contained web page with all the HTML, CSS, and JavaScript you need. It even downloads all your silly images and animated gifs.

Pro tip: Your argument is 189.3% more valid when using animated gifs.

Pro features coming soon

Currently in beta, there are a number of features coming to Blazon that make it the tool for speakers and training professionals.

  • Remote Control: Start a presentation and drive it with your phone or tablet. Your speaker notes appear also appear on your device!

  • Audience Follow Along: Give your audience a URL they can use to follow along with your presentation. They can go back and view previous slides, but they can't jump ahead of you!


Blazon is destined to become the best tool for technical presentations and training. Don't waste any more time coercing PowerPoint or Keynote.
