Generate AI prompts for your perfect storefront signboard
AI Signboard Prompt Generator is a free browser extension (Chrome, Firefox, Edge) that turns your business type, sign style, and color choices into ready-to-use prompts for ChatGPT, Gemini, Claude, Grok, and other AI image tools. Upload a photo of your real storefront and preview signboard concepts directly on it. The extension auto-matches sign type, style, and camera angle to your business, supports 7 in-app languages, and runs 100% locally, so no data ever leaves your device.
Hi Product Hunt!
I run a signage company in Hanoi (Quốc Đăng), and every week customers would ask "what style/color should my shop sign be?" without a clear idea. Explaining this back and forth, or hiring a designer just to test an idea, was slow and often expensive for small business owners.
So I built AI Signboard Prompt Generator, a free browser extension (Chrome, Firefox, Edge) that turns a few simple choices (business type, sign type, style, color tone, even an optional photo of your actual storefront) into a ready-to-use prompt for ChatGPT, Gemini, Claude, Grok, Copilot, and other image AIs. One click and you get a professional, detailed prompt instead of staring at a blank box.
It started as a simple English-only tool, but based on feedback I added:
- 7 in-app languages (EN, VI, AR, ZH, FR, RU, ES)
- A "photo mode" that previews the sign directly on your real storefront
- Auto-matching of sign type, style, camera angle, etc. based on your business type
Everything runs locally in the browser, no data ever leaves your device.
Would love to hear what you think, and what features would make it even more useful for you!
AI prompt generator for storefront signage. Upload a photo, pick a style, and get a ready prompt for ChatGPT, Gemini, Midjourney.
AI Signboard Prompt Generator helps store owners, signage designers, and marketing teams create ready-to-use AI prompts for storefront signboard design in just a few clicks, then use those prompts on your favorite AI image tools.
WHAT IT DOES
Instead of guessing how to describe a signboard to an AI image generator, this extension gives you a simple form. Pick your business type, sign type, design style, color tone, time of day, and camera angle, and the extension instantly writes a detailed, well-structured prompt for you. Copy it with one click and paste it into the AI tool you prefer.
WORKS ON ANY WEBSITE
Click the extension icon on any page you are browsing, including the AI platform itself, to open a small floating panel. You can drag it anywhere on the screen and resize it to fit your workflow. It stays out of your way until you need it.
SMART SUGGESTIONS BASED ON YOUR BUSINESS TYPE
Choose your business type (coffee shop, restaurant, bakery, salon, clinic, and many more) and the extension automatically suggests a matching sign type, design style, color tone, and lighting, so you get a sensible starting point instead of a blank form. You can still change any option yourself.
OPTIONAL REAL PHOTO MODE
Have a photo of your actual storefront? Upload it, and the extension switches to a special prompt mode that asks the AI to add the new signboard directly onto your real photo, keeping the building, background, and surroundings unchanged. This gives you a realistic before-and-after preview instead of a completely new, imaginary scene.
SUPPORTS MANY AI PLATFORMS
The extension can tailor the prompt format for the AI tool you prefer. Just pick your platform from the dropdown.
OTHER HANDY FEATURES
- Copy the prompt only, the photo only, or both together in one click.
- Suggested negative prompt to help avoid blurry text, distorted letters, or watermarks in the generated image.
- Save your favorite prompt combinations so you can reuse or compare them later.
- A multilingual interface, so you can use it in your own language.
- Light and dark mode to match your browser theme.
- Drag to move and resize the panel, plus a maximize button for a larger working view.
YOUR DATA STAYS ON YOUR DEVICE
Any photo you upload and any settings you choose are stored locally in your own browser only. Nothing is uploaded to our servers or shared with anyone. You are always in control, and you can remove a saved photo at any time with one click.
WHO IS THIS FOR
Signage and advertising companies, store owners planning a new storefront sign, marketing agencies preparing design concepts for clients, and anyone who wants a fast, realistic way to preview signboard ideas before committing to a physical build.
