Product Concept Studio

Built for you during the Keystone AI Enablement engagement. A working prototype with real limits — yours to keep and change.

What it is

A reusable AI image assistant that takes a plain product photo plus a customer's logo and generates a photorealistic, ready-to-use marketing image of that product — decorated with the logo, sitting naturally in a real-life setting.

What it's for

Turning your blank, white-background catalog shots into living marketing and sales imagery — the kind of "here's the product, branded, in the world" picture you've wanted but that's never been worth shooting per product. Use it for your website, distributor-catalog listings, sell sheets, and showing a prospect "here's your logo on this product" before they order.

It does not touch your production art. A designer still builds the real vector proof — this makes a picture, not a manufacturing spec.

Build it on your own stack (about 5 minutes)

Because this one generates images, build it in a tool that can: a Gemini Gem or a ChatGPT Custom GPT. (Claude Projects don't generate images, so this is the one tool that isn't Claude-friendly.) The recipe is the same in either:

  1. Create a new assistant and name it Keystone Product Concept Studio.
  2. Paste the instructions block (at the bottom of this page) into its instructions field.
  3. Save. It generates images — that behavior is baked into the instructions.
  • Gemini (gemini.google.com) → Gems → New Gem — free to build and use; what it was first built in.
  • ChatGPT (chatgpt.com) → My GPTs → Create — building needs a paid plan.

See Learn → Working With Images for more on AI image tools.

How to use it

  1. Open your Keystone Product Concept Studio assistant.
  2. Upload two images: a clean product photo (white background is best) and the customer's logo/art. (If your art is a vector PDF, export it to a PNG/JPG first.)
  3. Type a short request with three things: the decoration finish, where it should be, and who it's for. Example: "Full-color imprint, sitting on a desk in a busy office, for a local high school."
  4. The Gem returns a finished image. Want a different setting? Just ask again — same product, new scene.

The input recipe that produces the best results: a clean, well-lit product photo on a white background + a high-contrast, simple logo. That combination is where it shines.

Making it publish-ready (the watermark workaround)

The free Gemini app leaves a small sparkle/watermark in the corner — fine for a quick mockup, not for a marketing page. For a clean, web-ready final:

  • Regenerate it in Google AI Studio — paste the same description and re-upload the product + logo. AI Studio doesn't add the watermark. (Free.)
  • Or, for the highest-resolution clean output at volume, the paid image API is the route — a conversation for later.

If it breaks

Try these before reaching out.

The logo comes out garbled or unreadable

You probably asked for the product small or in the background. Ask for one product, toward the front of the frame, in focus — close enough that the logo reads. One featured product is the rule.

The whole scene gets branded (logo on walls, posters, shirts)

You named the customer or event as the setting. Describe the setting generically instead ("a plain modern office desk") and let the brand live only as the logo on the product.

It looks like a fake, floating product ad

Ask for it off-center, at true desk scale, nestled among the normal clutter, with only moderate background blur. That makes it read like a real snapshot.

The decoration looks weak — especially glass/crystal etch or fine art

This is the tool's hard edge. Frost etch on clear glass and fine line-art need a very clean product image and a high-contrast logo to hold up. Use the ones that come out clean, and fall back to a real photo for the few that don't.

Make it yours — you own the whole thing

The real gift: you have the full instructions, so you can change how it behaves. The COMPOSITION RULES section is where the look lives — the candid-not-hero framing, the one-product-in-front rule, the neutral-unbranded room. The decoration finishes (full-color / metallic gold / frost white / laser etch) are listed too, so you can add or adjust how a finish renders.

Paste the instructions into any AI and say "help me adjust this so it does X." You're starting from 90% done, not a blank page.

What this prototype does — and doesn't (yet)

This is a working prototype — usable now, with real limits. The full, hardened version is a separate, paid build.

Works now for: clean product shots with bold, simple logos (most of your promo line — tumblers, drinkware, bags), one product per image, generated one at a time and chosen by a person. Free to use, web-ready when finalized through AI Studio.

The full build would add: batch runs (drop in a product list, get many images at once); composing your actual logo art onto the product instead of re-drawing it (which fixes the crystal/fine-detail cases); higher-resolution, watermark-free output; output sized straight for distributor-catalog listings; and a simple drag-and-drop tool the whole team logs into.

The full instructions (the engine — yours to keep and tweak)

Copy everything in the box and paste it into your assistant's instructions field.

You are Keystone Product Mock-Up Studio — an image generator for Keystone Recognition / Brightmark Imaging, a custom recognition and promotional-products company. You turn an uploaded product photo plus a customer's logo into ONE photorealistic, PUBLISHABLE marketing mock-up: that product wearing that logo, sitting naturally in a believable, candid real-life setting.

OUTPUT: an IMAGE ONLY. No description, no caption, no preamble. If the product photo or the logo is missing, ask for just that one thing; otherwise generate the image.

INPUTS: a product photo (uploaded); a customer's logo/artwork (uploaded; may be flat black line art); a decoration finish (default "full-color imprint"); a setting in plain words (may be brief — you fill in composition).

ALWAYS APPLY THESE COMPOSITION RULES:
- CANDID, IN-USE — not a hero/studio shot. The product sits naturally where it would really be. Nobody holds, lifts, sips, or presents it.
- LEGIBILITY VIA DEPTH, NOT SIZE. ONE featured product toward the FRONT, in sharp focus, decorated face angled to camera so the logo reads; background slightly soft. Not oversized, centered, or floating. Never scatter multiple small branded copies.
- TRUE-TO-LIFE SCALE against hands, mugs, laptops, the table.
- ENVIRONMENT NEUTRAL & UNBRANDED. The logo appears in EXACTLY ONE place: on the featured product. Plain walls; generic décor only. NO posters, banners, signage, wall text, or branded clothing. Props carry no readable text/logos. THIS HOLDS EVEN IF the user names the customer/brand or event — use that name ONLY as the logo on the product.

PRODUCT & DECORATION:
- Keep the uploaded product EXACTLY as supplied — shape, color, material, proportions. Never redraw it.
- Reproduce the customer's actual UPLOADED logo faithfully — never invent it.
- Apply the logo only to the product's decoration area, realistic scale, in the named finish:
   full-color imprint → actual colors, crisply printed.
   metallic gold → flat art re-rendered as reflective metallic gold.
   frost white (crystal/glass) → frosted sandblasted white etch; setting shows through the glass.
   laser etch (metal/wood) → tone-on-tone engraved, no color.

CLEAN EXPORT: natural lighting, real shadows/reflections. The final image must be clean and web-ready — NO caption, label, watermark, or text overlay anywhere.
