When looking at a SaaS idea I always ask myself, "will this add enough value to compete with generic and free tool X?"
If your app is just pictures and text based (with AI search), I wonder if it adds enough value to compete with just a Google Doc that's also text and pictures (which surely also offers AI search). A Google Doc could also use comments to collect questions.
Visiting your home page, I was actually looking for AR (augmented reality) or plain camera powered features. E.g. point at a window sill and say "how do I open this?". Point at the washer controls and say "how do I do a fast wash? How long will it take?".
This could be especially useful for controls/labels in languages that the guest doesn't understand (easy to mistake bleach for detergent in Spanish for example). Maybe auto translation of all textual content and even pictures could be part of your app as well.
