- Lifelike avatars that lip-sync to your script.
- Free version available for quick use.
Use Case:

3. Gamma – AI-Powered Presentations That Don’t Look AI-Generated
Website: Gamma.app

Gamma helps you build beautiful slide decks and visual content using just text prompts. Unlike Canva or PowerPoint, it leverages AI to structure content and apply modern aesthetics automatically.
Why It Deserves More Hype:
- Saves time on structure and design.

Why It’s a Hidden Gem:
- Vector outputs are editable in tools like Figma and Illustrator.
- Ideal for blog headers, product illustrations, and UI mockups.
- Simple UI and surprisingly accurate for abstract concepts.
Use Case:
I needed minimal illustrations for a tech blog. Instead of downloading generic vectors, Illustroke created custom SVGs that matched the brand tone perfectly.
