Manually writing descriptions, tags, or alt text for hundreds of visual assets is a tedious, unscalable process that slows down content production. For e-commerce founders and digital marketers, this creates a massive operational bottleneck.
As digital libraries grow, teams often face a severe lag between acquiring visual assets and actually categorizing or describing them for end-users and search engines. Relying on manual data entry makes it incredibly difficult to scale your asset management.
By leveraging a no-code platform like Momen, you can integrate multimodal AI to build an automated image description workflow. This instantly translates visual inputs into structured, usable text—allowing you to build a professional AI image captioning app without writing a single line of code.
Understanding the Automated Image Description Workflow
An automated image description workflow is an application that utilizes a multimodal AI model (capable of processing both images and text) to analyze an uploaded photo and output a relevant caption, summary, or set of tags.
This workflow eliminates manual data entry, bridging the gap between visual media and text-based databases. It transforms a slow, human-dependent task into an instant, automated background process.
Typical use cases include:
- Generating automated SEO alt text for blogs at scale.
- Creating initial drafts for e-commerce product descriptions.
- Cataloging digital asset libraries with accurate metadata.
When NOT to use it: Avoid using this workflow for tasks requiring precise technical measurements or critical safety inspections. AI models can hallucinate details, which might misrepresent physical specifications and present severe business or safety risks.
To understand the underlying models driving this technology, read our Beginner's Guide to Multimodal AI and explore the AI Agent Overview documentation.
Step-by-Step Guide to Building the Workflow in Momen
Data Storage
First, we need a table to store the original images and the metadata generated by the AI.
- Data Model: Go to the Data tab and create a table named product.
AI Agent Configuration
We need to configure an AI Agent capable of "seeing" the image and returning structured data.
- Inputs: Add an input named product_image and set its type to Image.
- Prompt Template:
Role: Expert E-commerce Copywriter.
- Goals: Analyze the user's product_image, identify key features (category, material, style, condition), and write descriptive copy.
Structured Output: To ensure the backend can save the data easily, set the output type to Structured. Define an object body containing:
- title (String)
- description (String)
Actionflow Construction
The Actionflow handles the logic of passing the image to the AI and saving the result. Set the Execution Mode to Async (Asynchronous) in the right panel to smoothly manage the AI's processing time.
- Input Node: Define a parameter product_image (Type: Image).
- AI Node: Select the Start conversation action.
Select AI: Choose the agent configured in the previous step.
Inputs: Bind product_image to the Actionflow's input data.
Database Node: Select Insert data for the product table.
image: Map to Actionflow data / input-data / product_image.
- title: Map to Actionflow data / AI node / data / title.
- description: Map to Actionflow data / AI node / data / description.
UI Construction & Interaction
Now, build the interface to trigger the process.
- Component Tree:
Image picker: For the user to upload the photo.
Button: To trigger the AI analysis.
Interaction Configuration:
Select the Button and go to the Interaction panel.
- Event: OnClick -> Actionflow.
- Action: Select AI Image Description.
- Parameters: Bind product_image to the value of the Image picker component.
Verification
- Click Preview in the top right corner.
- Upload a clear product image (e.g., a glass teapot) using the Image Picker.
- Click the "Get Started" (Button).
- Navigate to Data Source -> Database and check the product table. You should see a new record with the uploaded image and AI-generated text.
Try It Yourself And Expand Your App
To truly understand how this logic operates, we encourage you to explore the working template. Seeing the project structure in practice is the best way to master no-code AI vision capabilities.
You can customize the AI prompts to fit specific brand voices perfectly. For instance, tweak the instructions to change the output from a simple image caption to an engaging social media post.
By inspecting the pre-built backend Actionflows, you will quickly understand how visual data is passed to the AI and stored seamlessly. Once you are comfortable, try exploring advanced features like processing multiple images at once via looping mechanisms to supercharge your productivity.
