AI Signboard Prompt Generator by Eyelight Việt Nam

Preview your shop sign before you build it.

AI Signboard Prompt Generator turns a few clicks into a ready-to-use AI image prompt for storefront signage. Pick your business type, sign type, style, and color tone, and the extension writes a detailed prompt you can paste straight into ChatGPT, Gemini, Claude, Grok, or Microsoft Copilot to see what your sign could look like.

Key features

• Photo Mode: upload a real photo of your storefront to get a prompt optimized for previewing the new sign directly on your own building, instead of a generic AI scene.
• 6 sign types covered: Alu (aluminum composite) signs, backlit/LED letters, light boxes, printed banner/decal signs, and flag signs.
• Copy Prompt + Photo in one click, so pasting into your favorite AI chat brings both together.
• Favorites and history so you can save your best prompts locally and reuse them anytime.
• 7 interface languages: English, Vietnamese, Arabic, Chinese, French, Russian, Spanish.
• Works on any website, with the panel floating over whatever page you're on.

Your data stays yours

Everything, including any photo you upload, is stored only in your own browser (storage.local). Nothing is uploaded to any server. The extension only opens outbound links you click yourself, such as quangcaoktd.com or the Zalo contact button.

Who it's for

• Shop and business owners who want to visualize their signage before ordering.
• Sign makers and designers who want a fast way to mock up concepts with clients.
• Anyone who wants AI-generated storefront sign ideas without learning prompt engineering.
