| Theme | Representative Quote |
|---|---|
| Positive | I love the technology of AI for generating purposes, because I strongly believe that it is a tool that we can use in everyday life with content creation. (N136 1) |
| Open/Interested/Willing to Try | I’ve never tried it before but I would be open (P4) |
| Indifferent | I wouldn’t care if it was AI or not. (N216) |
| Skeptical | If a recipe was created by AI, I would be skeptical. (L233) |
| Negative | I dislike the idea of AI so I am biased against it. (N1) I don’t want to make mustard gas because an AI told me it’d be a cake or something. (L144) |
| Theme | Representative Quote |
|---|---|
| Benefits of AI | I trust AI-generated information more than human generated, as AI-generated can provide less biased data. (M25 1) I feel as though AI could be more trustworthy in a way because it can take in more information (N334) |
| Assumed Recipes Would Be Decent Because They Were Based on Existing Sources | Recently I’m realizing more that AI just gathers information and pulls it all together. So i feel like it would generally make decent recipes and I would still try them. (N336) |
| Previous Experience with AI—Positive | I often use AI and find it very reliable. (N213) I use chatgpt to lookup recipes all the time and it seems to be pretty consistent but faster than information I can gather when trying to find a recipe via pinterest. (N179) |
| Quality vs. Source | I don’t really care how it’s generated, as long as the user interface is good and the recipes are good. (N172) If the recipes on an AI-generated blog look tasty, healthy and easy to follow, I’d totally give it a shot. The way the recipes are created doesn’t matter much to me as long as they’re delicious and practical, I’m in! (N8) |
| Further Verification Needed | I think it would be fine, as long as humans could leave reviews. If it’s an AI recipe with four or five stars from humans, I would definitely use it. (N106) If I knew it were AI-generated I would probably look closer at the measurements for ingredients and be more open to adjusting them to what I think would be better. (N243) |
| OK if Tested/Verified by Humans | I’m fine if AI is involved in the process, but I want the finishing touch to be human. (L101) AI generated anything would not change my likelihood of using it, of course all things AI generated need to be human checked for quality so we don’t get websites that are unusable. (N69) |
| AI is “Not There Yet” | While i do believe ai can get to the point where it can provide instructions for good food, i don’t think it’s at that point yet. (L129) |
| AI Is Not Creative/Cannot Optimize | I don’t think AI would be able to come up with new recipes—it could help pull them from the internet, but I wouldn’t trust it to come up with something new. (L246) An AI-generated recipe is more like a recipe draft; a start, but not a finished, publishable recipe with a good reputation due to repeated trials. (L228) |
| Benefits of Humans—Prefer Human Creation and/or Testing | Knowing that another person has written and actually tested out a recipe before using it makes me more confident that the recipe will turn out how I want it to. (L33) |
| Benefits of Humans—Prefer Human Touch | AI feels less personal. My idea of the website was that it was created to help students who struggle to find and prepare meals for themselves. If the website was generated by AI, I would feel less cared about, in a way. (L91) From my understanding the reviews were also AI generated, and that makes me feel like I’m being tricked/lied to. (L125) I think using AI would take away from the humanness of cooking. Kitchens are the metaphorical “heart” of a home. With the use of AI, we loose the deeper understanding of people and their cultures. (L71) |
| Limitations of AI/Concern for Taste | I feel like I wouldn’t trust it as much since the AI has never tasted food. (L42) AI got no taste buds, I ain’t gonna be skimming through a site that has tasteless recipes or AI-generated ones. (L283) |
| Limitations of AI—Inaccurate/Unreliable/ Untrustworthy | My personal worry is that an AI-generated blog might not understand how to actually make the food and might end up over cooking something or undercooking something like the meat in a dish. (L127) Sometimes AI doesn’t get things right. I wouldn’t want it ruining my dinner. (L220) |
| Previous Experience with AI—Negative | NEVER would I use an AI generated recipe blog. I’ve seen AI make too many weird things. Once I saw an AI generated “vegetarian” recipe that included chicken stock… (L153) I’ve tried to create AI recipes before with little success so I would be a little wary about the results. (L137) |
| Ethical Concerns | Using an AI generated blog seems relatively lazy to me and in my opinion lacks a personal touch. (L55) I would under no circumstances use a recipe that was AI-generated, because AI technology lifts from recipes written by real people, thereby stealing content and adding competition for ad dollars and other sources of income for these people.
