The Gmail approach doesn't interest me, but a method using Amazon product lists and a search with autocomplete and images (to help me identify the products I don't know in detail) would be more useful.

Haven't tried your product as a result of the Gmail thing so I'm not sure if you already do this, but you could prompt people with things like:

What model fridge do you have? (Delete - I don't have a fridge) Washing machine Microwave etc

Thanks, you can manually add products through search (with images, title, brand, etc)

We don't prompt or recommend what to add at this point, but it's an interesting idea if you can do it well. I appreciate your feedback!
