Some feedback:

When I enter a url to give me feedback for, it prompts signin, then returns you to the homepage instead of a review for the url you wanted a review for.

Conversations on the left should be named. Right now they're just "new conversation". These name themselves after the conversation is complete, but you should be able to fire off a query to a smaller LLM based on the prompt to name them asap.

The biggest thing though, the feedback it gave me was incorrect. Not the subjective parts, but the objective bits were incorrect. Here's what it told me:

> Change: Make the first viewport a contained product argument:

> 1. Navigation and one primary action

> 2. Short headline and supporting sentence

> 3. A real prompt-to-interface example

> 4. One compact proof point or “before / after” comparison

My landing page (https://diffui.ai) has nav and one primary action. It has a short headline and a supporting sentence. It has a real prompt-to-interface example. It has a before (prompt) and after (multipage web design) in the example.

I suspect that it got confused due to this being an interactive example, but a lot of this (the headline/supporting sentence) are present in the screenshot it took.

Overall though not a bad start. Good work sourcing references.
