Gendo is a browser-based platform that uses Machine Learning and artificial intelligence tools to transform text and graphic cues into architectural visualizations for architecture projects in a fraction of the time it traditionally takes an architect.
Every Gendo tool is fed instructions through a “prompt”, a text description of what the user wants to see, with details like subject, color, mood, materials, lighting, style, and composition. The more descriptive a prompt is, the more information the tool will have to work with.
Prompting is an art, and mastering it means unlocking the full potential of AI. While general rules apply across most AI models, each platform has its own unique mechanics that influence the final output.
A prompt is the text description users provide to the AI tool to generate a response—in our case, an image. The user prompt tells the AI what users want to see, including details like the subject, colors, mood, materials, lighting, style, and composition. A well-structured prompt leads to a more accurate and visually compelling output.
Gendo prompts are composed of five main categories:
[Main subject], [Context & Key features], [Atmosphere & Lighting], [Style], [Extra Keywords]
On Gendo, prompting varies across different tools, as each one is designed to serve a specific purpose to meet different creative needs. To explore each of our tools in depth, you can visit the guide How to Use AI Image Generator Tools?.
The Main Principles for Text-to-Image generators are:
- No commands, don’t use conversational language. Describe what users want to see.
- Bad Prompting: “change color”, “remove the curtains”, “don’t make it dark”, ”make it bigger”
- Good Prompting ”a large red velvet sofa”, “bright and airy atmosphere”
- Be clear and specific rather than using generic descriptions. Clearly describe the key elements how users want to see them.
 |
| Bad Prompting: | Good Prompting: |
| “A vase on a table” | ”a rounded wooden coffee table with a blue glass vase on it” |
The more precise the users are, the more accurate the result.
 |
| Bad Prompting | Good Prompting: |
| "a castle" | ” A majestic castle on top of a mountain overlooking a winding river” |
Order matters in good prompting. AI prioritizes the earlier terms in the user's prompt. Words placed at the beginning carry more weight, meaning that starting with the main subject ensures the AI understands the most important element first.
An example of great Prompting:
 |
A neon-lit city street with glowing billboards and people walking. The futuristic skyline in the background features a towering glass skyscraper reflecting the sunset. The building’s sleek, modern design includes sharp angles and mirrored surfaces. Cinematic lighting, ultra-detailed, photorealistic, 8K architecture photography. |
An example of even greater Prompting:
 |
A futuristic glass skyscraper towering over a vibrant city skyline, reflecting the warm hues of the sunset. The building’s sleek, modern design features sharp angles and mirrored surfaces. Neon-lit streets below are filled with people walking under glowing billboards. Cinematic lighting, ultra-detailed, photorealistic, 8K architecture photography. |
The ideal prompt should include all essential elements users want to control. Any details not specified will be left to the AI’s interpretation and creativity.
Recommended formula:
[Main subject], [Context & Key features], [Atmosphere & Lighting], [Style], [Extra Keywords]
 |
A modern villa with a swimming pool in front, surrounded by pine trees, natural day light, contemporary style, architectural photography, high resolution |
Users should be descriptive but avoid complexity. There is no strict rule that "shorter is better" or "longer prompts work best"—it all depends on clarity and structure.
What’s Bad Prompting?
Phrases like "bustling metropolis," "contemporary sculptures," and "dynamic urban life" add unnecessary conceptual descriptions rather than guiding the AI on specific visual elements. The excess detail resulted in blurry and less-defined architectural features.
What’s Good Prompting?
Good prompting includes all critical details without overloading it with unnecessary descriptions and retains all essential architectural details while improving clarity and processing efficiency.
| Bad Prompting: | Good Prompting: |
 |
| “A futuristic high-rise tower standing at the heart of a bustling metropolis, its sleek glass facade reflecting the warm glow of the sunset. The skyline is dotted with other skyscrapers, while tree-lined boulevards and pedestrian-friendly spaces weave through the urban fabric. In the foreground, an expansive plaza with contemporary sculptures invites visitors to gather and admire the architectural marvel. This ultra-detailed image captures the vibrant energy of the city with cinematic precision, blending modern design with dynamic urban life.” | A futuristic glass skyscraper towering over a vibrant city skyline, reflecting the warm hues of the sunset. Surrounding urban landscape with tree-lined streets and a lively plaza, cinematic lighting, architectural visualization, ultra-detailed |
In this example, the shorter version preserves all key architectural details while improving AI processing efficiency, ensuring that even small elements remain clear and well-defined.
Users should ensure that each element is clearly separated and precisely defined when describing patterns or materials. Avoid using multiple or too complex adjectives that may cause confusion, and clearly separate and define each object to ensure accurate representation.
| Bad Prompting: | Good Prompting: |
 |
| “a long narrow corridor with a richly decorated ceiling and red walls adorned with intricate white floral and geometric patterns, black and white checkered tile design floor” | “a long narrow corridor, red white floral patterned walls, black and white tiled floor” |
In these examples, the bad Prompting combines floral and geometric details, making the AI blend them into an inconsistent result. Using multiple adjectives like "richly decorated ceiling" added complexity, leading to a blurry and less accurate outcome.
The second prompt was more structured and direct, specifying "red white floral patterned walls" rather than mixing multiple pattern types.
What does the perfect Prompt look like?

Still not getting the wanted results? Here is the checklist for an AI-friendly flow:
- Make sure to follow the right order of the elements.
- Describe what the users want to see, but avoid complexity.
- Ensure that all essential objects are included and avoid excessive adjectives.
- Structure the elements in a clear and logical way for a seamless composition.
- Clearly distinguish between different objects and design elements for a more accurate result.
