Perplexity alt text generator

What the Perplexity alt text generator does

This Perplexity alt text generator writes alt text from a short description you type, tuned to skip the habits Perplexity falls into when asked directly: a bracketed citation marker occasionally left attached to a sentence, and a formal, encyclopedic register better suited to a reference answer than the short, function-focused line a screen reader actually needs.

It doesn't look at an uploaded image. This site doesn't process images at all, so you describe what the image shows and what it's for, and it comes back as alt text sized for a screen reader. It runs on our AI server, not your browser. You get 5 free runs every rolling 24 hours, no account and no signup.

Alt text

What alt text actually is, in plain terms

Alt text is the written alternative to an image, read aloud by a screen reader in place of the picture and shown as fallback text if the image fails to load. It's an accessibility feature first: it needs to describe what the image does in context, not just what it looks like. Function over appearance, and decorative images get an empty alt attribute so a screen reader skips them instead of announcing something meaningless.

How it works

How to write alt text with Perplexity-style input in three steps

Three steps, and no citation marker to strip out afterward.

Step 1

Describe the image: what it shows, and what job it's doing on the page.

Step 2

Press Generate. Your description is sent to our AI server and comes back as concise alt text.

Step 3

Read it as a screen reader would announce it, trim anything about appearance rather than function, and paste it in.

Consequences

What a Perplexity-style answer actually breaks

Alt text asked for directly through Perplexity sometimes carries a bracketed citation marker attached to a sentence, a reference that resolves inside Perplexity's own interface and reads as a stray, meaningless character once it lands in an alt attribute.

Perplexity's formal, cited-answer register also tends to produce alt text that reads like a complete, encyclopedic sentence, accurate but longer and more formal than the short, functional line a screen reader user actually benefits from hearing.

The Perplexity tells

Why Perplexity's alt text answers need a second pass

Left to its own defaults, Perplexity converges on a specific, recognizable set of habits, shaped by its job as a cited answer engine.

A trailing citation bracket

A [1] or similar marker attached to the answer, meaningless once pasted outside Perplexity's own interface.

Formal, encyclopedic phrasing

A complete, accurate sentence that reads like a reference description rather than a short, functional line.

Source-hedged wording

"According to the description provided" or similar framing appearing where a plain functional description is needed instead.

Length that runs long

A precise, qualifier-heavy sentence longer than the single clear line a screen reader announcement calls for.

Straight answer

Does Perplexity-generated alt text actually meet accessibility requirements?

Not automatically. Alt text written from a good, specific description can genuinely meet the intent of accessibility guidelines. Alt text written from a vague one, or left unedited, often doesn't, and a more formal tone doesn't fix that, it just adds words.

The generator is only as good as the description you give it. A specific description of what the image shows and does produces alt text worth keeping. Read every result before you publish it, and trim anything that describes appearance rather than function.
