How to Create Course Slides Using Gamma

Open Gamma and choose "Generate" to start a new AI-created presentation. You've got two options. The first is typing a brief description of your lesson topic — something like "Introduction to watercolor techniques for beginners, covering materials, basic washes, and color mixing." Gamma will generate a complete outline and then build slides from it.

The second option, and the one I'd recommend for course creators, is pasting an existing outline. If you've already mapped out your lesson in Notion, Google Docs, or any text editor, copy the outline and paste it into the prompt field. This gives Gamma specific structure to work with instead of guessing, and the results are closer to what you actually want to teach. Gamma also supports importing directly from Notion if you connect the integration.

After you submit your prompt or outline, Gamma takes about 30 seconds to produce the deck. It creates individual slides with headings, body text, and stock images or icons. The number of slides depends on the length of your input — a five-point outline typically becomes 8–12 slides, including a title slide and a closing slide.

Review what the AI produced before you start editing. Scroll through every slide and notice the overall structure. Is the flow logical? Did it interpret your outline correctly? Are there slides that should be combined or split? This quick review saves time because it's easier to restructure now than after you've edited individual slides.

Gamma offers preset themes that control colors, fonts, and overall visual style. Pick one that feels close to your brand or teaching style. You can also adjust individual elements — change the background color, swap fonts, or select a different layout for any slide. The card-based layout system is flexible: each slide can use a different arrangement of text, images, and media.

For course slides specifically, favor layouts that give text enough room to be readable. A full-bleed image with a few words overlaid looks great in a keynote talk, but course students often review slides after the lesson as reference material. They need enough text to make sense of the slide without your live narration.

This is the step that matters most. The AI-generated text is a starting point, not finished content. Read every slide and rewrite the body text in your own voice. Replace generic phrasing with your specific examples, your terminology, and your perspective. If a slide says "there are several approaches to this topic," replace it with the actual approaches you teach.

Check facts carefully. AI text sometimes includes plausible-sounding statements that are vague or incorrect. If a slide references a statistic, verify it. If it names a technique, make sure it matches what you actually teach. The time you spend editing here is the difference between slides that sound like you and slides that sound like everyone else.

Upload your logo and place it on the title slide. If you've got brand colors, apply them through Gamma's theme editor — set your primary color and accent color, and the theme propagates them across all slides. Consistent branding across your slide decks helps students recognize your materials and gives your course a more polished, cohesive feel.

Gamma gives you several ways to use your finished slides. You can present directly from Gamma using a shareable link — students click the link and view the slides in their browser, no software needed. You can embed the presentation in a course platform that supports iframes. Or, on paid plans, you can export to PDF or PowerPoint for upload as a downloadable resource.

For course creators, the most practical path is often exporting a PDF. Students can download it, annotate it, and reference it later. If your course platform supports embedded content, the shareable link also works well — students view the slides inline without leaving the lesson page.

The AI produces much better results when you give it a structured outline rather than a vague topic description. If you've already written out your lesson flow — main points, sub-points, key examples — paste that in. The slides will match your actual teaching plan instead of the AI's guess at what the topic should cover. Spending five minutes organizing your outline before opening Gamma saves twenty minutes of rearranging slides afterward.

It's tempting to skim the AI-generated text, fix a few typos, and call it done. Resist that. The text needs rewriting, not copyediting. AI-generated slide content reads like a committee wrote it — technically accurate-ish but devoid of personality or specificity. Your students are taking your course because of your expertise and perspective. Put that on the slides.

Gamma sometimes packs too much onto a single slide. If a slide has more than one main idea, split it into two. Course slides work best when each slide makes one point clearly. Students process information in chunks, and a crowded slide with three competing ideas teaches none of them well.

The biggest limitation is content quality. AI-generated text is a draft, and often a rough one. Headings are generic, body text is padded with filler sentences, and the AI occasionally includes information that's vague or outright wrong. You can't use Gamma-generated slides as-is for a course you charge money for. Budget real editing time.

Gamma offers less design control than traditional slide tools. You can't pixel-perfect position elements the way you can in Keynote or Google Slides. The card-based system is flexible within its constraints, but if you need precise layouts — overlapping elements, custom animations, exact spacing — you'll find the system limiting. For most course slides, the default layouts are sufficient. For highly visual or design-heavy presentations, they may not be.

The free tier includes a Gamma watermark on all presentations and doesn't allow PDF or PowerPoint export. If you need clean, unbranded slides for a professional course, you'll need the Plus plan at $10/month. That's reasonable for active use, but worth noting if you're evaluating free options.
