✅ Our Test
We signed up with our Google account on the website.On the main page we were directed to, we clicked on the “Generate new kards!” button.
We were suggested to enter or import the materials. There was an interesting way to generate cards from just 3 keywords using AI. To use it we clicked the “Prompt” button. Then We submitted our keywords- “Ancient Roman Empire.” Selected the amount of cards we want to generate- 10.
KardsAI User Interface
Before generating our question cards, we had to preview one of them to check if they were relevant. We did it by clicking the “Preview” button. And the last step was to click on another one- “Generate”.
After those steps, the website directed us back to the main page and asked us to wait a little bit. It took us about 20 seconds to wait until the generation was completed. We entered to our cards deck, and here it is, 10 AI-generated question cards perfectly themed for history lessons. Generation cost us 200 gems when in the start we got1000for free.
