Generating Alt Text

The AltText.ai website lets you manually generate alt text for individual images, as well as bulk generation via CSV imports and web page scrapes.

Processing a Single Image

To generate alt text for an image:

  • Go to your Images library on the website.
  • Click the +Image button.
  • Enter either the image URL, or click the Choose File button to upload an image from your computer.
  • Click Add Image to submit.

Other Image Properties

  • Asset ID: Use this field to set your own unique identifier for the image. If left blank, a random ID will be assigned. The asset ID is useful if you plan on exporting your image data to use in your own system, and you need a way to tie the image back to your own internal identifier.

  • Alt Text Language: Set the language for the generated alt text. By default this value is set to your Account's default language. We support over 130 languages for alt text.

  • Human Review: Check the box to request a human review of the generated alt text. When you need the most accurate and descriptive results, nothing beats a real human reviewing and enhancing your alt text!

    Note

    Human reviews incur additional credit usage.

Ecommerce Images

If you are processing ecommerce images, select the Ecommerce Data checkbox to enter your product name and brand. AltText.ai will intelligently add these into your alt text.

Adding SEO Keywords

To enhance your alt text with specific keywords/phrases, or exclude specific keywords (negative keywords), select the SEO Keywords checkbox, then enter your keywords:

Adding SEO keywords for your alt text.

Using ChatGPT Modification

You can process the generated alt text through ChatGPT in order to add your own custom enhancements. It works like this:

Initial alt text ==> ChatGPT (with your prompt) ==> Final alt text for your image

When you check the box for ChatGPT modification, you will be asked to supply a ChatGPT prompt which will be used to transform the initial alt text into your final alt text for the image. Your prompt MUST include the macro {{AltText}} which will be where the initial alt text is added when sent to ChatGPT.

Note

ChatGPT prompts must be written in English, even if you are generating alt text in another language.

Example: Say your website sells surfboards, and you want to use your own custom brand voice for alt text. You could supply a prompt like this: Rewrite the following text in the style of a California surfer dude: {{AltText}}

Setting your ChatGPT prompt.

Info

To use the same ChatGPT prompt every time you generate alt text, set up the prompt in your Account: Settings page.

Bulk Importing via CSV

When you need to process a lot of images, you can import a CSV file of image URLs. Your CSV must contain specific columns for each data field you want to use. We offer both Google Sheets and sample CSV templates which contain the proper column headers, along with helpful instructions and requirements.

  • Go to your Images library, then click on the Import button at the top.
  • Select Upload CSV.
  • Click Choose File and select your CSV with your image data.
  • Enter an email address to be notified when the processing completes, then click Upload.

When you upload your CSV, you'll see a summary of the processing, and whether it was successful or not. If you have any obvious errors in your file, they will be reported on this page.

Info

CSV processing happens in the background, so please allow time for it to complete. You may not see your images added immediately, but they will usually appear within a few seconds after the upload.

Importing from Dropbox

You can select any number of image files from your Dropbox account and generate alt text for them.

  • Go to your Images library, then click on the Import button at the top.
  • Select Add from Dropbox.
  • Click the button to connect to your Dropbox account. You will see a window where you can login and select any number of image files to process.
  • After you've made your selections, you can start the alt text generation by clicking the Generate Alt Text button.

Info

Processing of Dropbox images happens in the background, so please allow time for it to complete. You may not see your images added immediately, but they will usually appear within a few seconds after starting the process.

Scraping Images from a Web Page

When you need to get alt text for all the images on a single web page, use our Scrape Page tool. This is useful if you (or your clients) have an existing website that needs alt text added, and you do not have a good way to extract the image URLs from your internal system. Page scraping also lets you enter ecommerce data and SEO keywords for the generated alt text.

To start a page scrape, go to your Images library and click on Scrape Page at the top.

Page scraping consists of two steps:

  1. Enter a URL (or provide HTML) and scrape the images from the page.

    Step 1 of scraping a page for image alt text.

  2. Select which images to process for alt text generation.

    Step 2 of scraping a page for image alt text.

Info

Page scraping does not execute javascript when detecting images. Therefore, scraping a web page which uses javascript to dynamically load images (e.g. "infinite scroll" or "lazy loading") may not result in the images being extracted.
