Course Creator Stack
Plan, record, produce, and publish an online course: from curriculum outline to finished video lessons, slide decks, and supporting materials.
Our Take
Built for someone producing a full course, not a single tutorial video. Synthesia's AI-avatar narration is the piece that changes the economics here, it replaces re-recording every time you need a script fix, which matters enormously across dozens of lessons and barely matters for a single video. Gamma handles the slide decks and Descript the editing, ElevenLabs is worth adding once avatar narration alone doesn't fit the tone you want for a given lesson.
True Cost & Exit
What this stack really costs to run, and how you'd leave it.
Monthly cost
from $56/mo (all core tiers)
Lean alternative
ChatGPT's free tier for curriculum planning plus Gamma's free tier (400 credits) for slides covers early course planning at zero cost; add Descript and Synthesia once you're actually recording lessons at volume.
Exit path
Your recorded lessons live in Descript's project files and your slide decks live in Gamma; neither ChatGPT nor Synthesia publishes a formal export policy, so export finished video lessons and slide decks to your own storage as each module is completed.
