Product description for Gemini

You have rough product notes and want Gemini to draft a store-ready description.

① Raw — what you might actually type

write a product description for our new water bottle

② Enhanced — what Pixiy hands back

CONTEXT

You are writing a product description for the website + Amazon listing
of a new insulated water bottle. The goal is to convert a browsing
shopper into a buyer.

Product facts (use only these — do not invent):
- 24 oz / 710 ml capacity, single-wall stainless steel.
- Triple-layered vacuum insulation: keeps cold 24h, hot 12h.
- BPA-free, dishwasher-safe lid (body hand-wash only).
- Six colorways. Lid styles: standard cap, sport spout, straw.
- Weight: 380 g. Mouth opening: 5 cm.
- Price: $34.99 USD.
- Brand voice: friendly, outdoor-curious, no superlatives ("the best",
  "amazing"), no hyperbole.

Target buyer:
- Active 25-40 year olds who hike, gym or commute.
- They have owned a cheap bottle before and didn't love it.
- They care about: thermal performance, weight, leak-proof.

Constraints:
- Write three deliverables (each as a separate section): (1) hero
  product title (≤ 70 chars), (2) website description (~120 words,
  scannable), (3) Amazon bullet points (5, each ≤ 200 chars).
- Mention thermal claims with the specific hours.
- Do not invent features that aren't in the facts list above.

TASK

Based on the context above, write the three deliverables now. Use the
exact section headings: "Title", "Website description", "Amazon bullets".

③ What changed — and why

  • Put all facts FIRST (Gemini long-context strength)
  • Explicit anti-hallucination rule ("do not invent")
  • Spec'd three distinct deliverables in one pass
  • Named buyer + brand voice so output sounds intentional, not generic
