Here is the outline for our AI product landing page. Tell me what is unclear before we design it.

Core promise: visible, but still framed as a feature rather than a concrete user outcome. Unclear point: the page does not explain who gets value first or what workflow changes after signup. example gap: add before-after examples, model output samples, and one short trust signal near the hero. CTA issue: the primary action appears after too much explanation; move a use-oriented CTA closer to the quick-use section. Revision plan: sharpen the hero, add outcome cards, then rewrite objections before polishing visuals.

Chat Prompt

Recommended model: Claude Sonnet 4.5

Landing Page Critique Chat

Review a landing page draft with a structured prompt for positioning, conversion clarity, example, objections, and next actions.

chat thread

Critique this 20-second prompt library launch video script.

Opening risk: the first line explains the library before showing a workflow problem. example gap: add one visible template-to-result transition by second six. Pacing: keep one idea per shot and avoid feature list narration. Revision: start with scattered tools, then reveal the Rivya prompt path.

Video Script Critique Chat

chat thread

Users ask how prompt templates connect to model pages and Studio. Need a docs article.

User goal: understand where prompt templates appear and how to run them. Prerequisites: published template, recommended model, and supported mode. Steps: open the prompt, review the example, run or copy it, then continue in Studio. Edge cases: unavailable model, draft template, or media still awaiting final approval. Related links: prompt library, model pages, and media checklist.
