The job
What the Llama alt text generator online produces
One alt attribute at a time, written from a description you type. You supply what the image shows and what it is doing on the page, and the run returns the finished line, ready to paste into the markup.
There is no image upload on this route. No drop zone, no URL field, no vision. The tool reads text. Anyone arriving expecting to drag a photo in should know that before they start, and anyone with images they cannot upload should know it too, because it is why this works when an upload tool would not.
The run happens on our server: 5 free runs per rolling 24 hours, a brief of 1 to 12,000 characters, no account. Plan a batch of images around five runs, or write several briefs and be selective about which ones need the tool at all.
The workflow
How to generate alt text in three steps
Three steps, and the first one decides everything the other two can do.
- Step 1
- Write the brief: subject, action, any text visible in the image, then the job the image does on the page and its link target if it has one.
- Step 2
- Set the constraint in the instruction box: one sentence, under 125 characters, no image of or photo of prefix. You have 300 characters to say it.
- Step 3
- Read the output, count the characters, and paste it into the alt attribute. Fix the brief rather than the output if it came back wrong.
Before you run anything
Sort your images before writing any alt text
Not every image needs a generated description, and running one on the wrong kind actively makes a page worse. Sort first, then run only what is left.
- Decorative
- Dividers, background flourishes, spacers. These take an empty alt attribute so screen readers skip them. Do not describe them, and do not spend a run on them.
- Informative
- The image carries something the text does not. This is the case the tool is for, and the brief should say what a reader would miss without it.
- Functional
- The image is a link or a button. The alt text describes the destination or action, not the picture, which is a distinction no captioning tool makes reliably.
- Complex
- Charts, diagrams, dense infographics. The alt attribute takes the takeaway only, and the detail belongs in a table or long description on the page.
Setup
What to put in the brief and the instruction
The brief holds up to 12,000 characters and the answer needs about 125, so there is no reason to be sparing. Extra context is what this route has instead of vision.
- The surrounding copy
- Paste the paragraph the image sits next to. Alt text that repeats the caption word for word is noise, and the model can only avoid that if it knows what the caption says.
- The purpose
- Product shot, evidence for a claim, step in a tutorial, author portrait. Each of those wants a different sentence from the same picture.
- Text in the image
- Transcribe signs, screenshots, labels and headings. This is the information a screen reader user loses completely, and it is the easiest to supply.
- The length rule
- Put the character target in the instruction field rather than the brief, so it reads as a constraint on the output rather than as part of the description.
Review
What to check before you paste it into markup
Three checks, and none of them takes longer than reading the line aloud.
First, accuracy. The output was written from your description, not from the image, so it can only be as right as the brief was. Look at the image and the sentence together and make sure the sentence is true of the picture.
Second, length and prefix. Aim near 125 characters, because some screen readers pause or cut off longer strings, and cut any opener like image of. Third, redundancy: if the alt text and the visible caption say the same thing, a screen reader user hears it twice.
The honest answer
Does alt text help SEO?
Search engines read the alt attribute, so a genuine description of the image is useful to them. That is the honest version of the claim and it is worth doing well.
What does not work is stuffing keywords in. It can hurt rankings, and it degrades the attribute for the person actually relying on it, which is a poor trade in both directions.
Write the description, and let the terms that genuinely belong in it appear because they belong. If a word has to be forced, leave it out.
Constraints
Llama alt text generator limits to plan around
Five runs per rolling 24 hours, counted from first use. One brief per run. No bulk mode, no site scan for missing attributes, no CMS integration, no plugin, no extension and no API.
No image handling of any kind, and no file formats to worry about, because no file is accepted. No history either, so keep your own record of what you wrote for which image.
It also makes no compliance claim. Generated alt text is a draft line for a human to approve, and on this route it is a draft written from your own description.
In practice
Where the Llama alt text generator fits
Retrofitting a page whose images have no alt attributes, where you can see the images and just need the sentences written. Writing alt text during drafting, before the images exist, so the markup is complete when they land.
Images you cannot upload anywhere are the strongest case: screenshots of internal tools, assets behind a login, artwork sitting in a design file. A description is all this route needs.
For a large library, the honest answer is that five runs per day is not the tool for it. Triage the set, handle the decorative ones with an empty attribute, and spend the runs on the images that genuinely carry meaning.
