Canva makes it easy to edit a thumbnail by hand. But what happens when you ask its AI and several agents to tackle the same brief?
Dave compares first attempts from Canva AI, Hermes, Grok and an OpenAI agent, then looks at the trade-off between editable designs, stronger visual ideas and an AI-generated likeness that does not quite look like him.
In this Field Note:
- Why Dave wanted to rethink his Operator Stories thumbnails.
- What Canva AI produced and how the agents' versions compared.
- Why the winning design's AI-generated version of Dave gave him pause.
- A practical takeaway: try the same task across tools and keep the human in the editing loop.
Canva Brush was not available to Dave on his account at the time, so this is not a test of that model or a controlled benchmark. The results reflect one brief and one attempt per tool.
What do you use to make your thumbnails: Canva, AI tools or a mix of both?
