Let me be plain about what this post is, in the first paragraph, because the first version of it was not. This is a list of the AI tools on the market that write image alt text, SEO titles, and meta descriptions, and I have used exactly one of them: the alt text generator built into Duda, which was perfect. The rest I have not used. The furthest I can honestly go on any of them is "I have heard good things," and on most I cannot go even that far; I can only report what they claim and what they charge. I am not writing this for you, dear reader. I am writing it for myself, my memory, my reference, because my memory does not keep lists and this weblog is where my lists live. I will share it with clients and prospects when the subject comes up, and if it helps a stranger, that is a bonus and not the purpose. What follows is a field guide for my future self: six tools, three fields, what each one says it does, what it costs, and the one working rule that will matter when I finally test them, which is that a generator that describes beats a generator that stuffs.
Duda's built in alt generator, the one I have used
This is the only first hand report in this post. On Duda, the website builder, the automatic AI alt generation wrote descriptions for a client's images at the moment they landed on the page, plain descriptions of what the photographs showed, and when the accessibility and SEO checkers ran, the site scored a perfect score on its image alt text. I could not have improved the batch by hand. No credits, no plugin, no settings page, no ceremony: the builder met the image at the door, before it could be published naked and forgotten. Everything else in this post gets measured against that experience when I get around to measuring it, because a perfect score from a tool I have actually watched work is the only benchmark here that is not a vendor's promise.
AltText.ai, alt text on WordPress, heard good things
I have not used this one. It is the credit based service I remembered this morning and went looking for, and it is the name that comes up most in the trade, which is the entire basis of the "heard good things." What it claims: one credit writes one image's alt text, a WordPress plugin backfills a whole media library in bulk and writes alt on every new upload, and it can pull the focus keyword from Yoast or Rank Math into the alt text, which is the stuffing habit I argue against below. What it costs, checked this fall: $49 a year for 1,200 credits, $189 for 6,000, $489 for 24,000, one time packs of 50 credits for $3, credits roll over, and advanced formats like AVIF and SVG bill double. When a WordPress client needs a backfill, this is the first one I will test, and this post exists partly so that future me remembers its name.
Yoast SEO Premium, titles and descriptions, and the question
I am a Yoast man and a Yoast expert, so Yoast itself I know cold, but its AI generation is new enough that I list it here on its claims like the others. Premium, about $119 a year, generates SEO titles and meta descriptions inside the editor, in the exact box you were about to type into, which is the right surface for it. It generates no alt text, and my standing question goes on this record too, because this post is my reference: why hasn't Yoast added this yet? Yoast already inspects every image on a page and already warns when an alt attribute is empty. The vision models are a commodity. Whether the answer is accessibility conscience, team ownership, or simple backlog, the gap is real, and the specialists below walked through it.
SEOPress PRO, bulk titles and descriptions, on its claims
Not used by me; listed because bulk is its claim and bulk is my recurring client problem, hundreds of empty title and description fields on programmatic and location pages. On its claims: $49 a year per site, bulk generation across post types, and a choice of billing, your own AI provider key or their managed credits. If it does what it says, it is the shape of tool that job needs: prompts that carry rules, batches that can be sampled, generation that survives page four hundred.
Rank Math Content AI, on its claims
Not used by me. Rank Math's built in AI generates titles, descriptions, and other content, priced in its own credits inside the plugin, including bulk meta for selected items. Its argument is residence: if a site already runs Rank Math, the generator is already installed, and not migrating a healthy site's SEO plugin to chase a feature is a principle I hold whether or not I have tested the feature.
AI SEO Tools, the free wildcard, on its claims
Not used by me, newest name on this list, and the one whose economics match mine, which is why future me should trial it early. On its claims: a free WordPress.org plugin that does both jobs, alt text and meta, writes into the fields of whichever SEO plugin is already running, works off your own API key to the major model providers at fractions of a cent an image, enforces a spend cap, and ships command line commands so a big backfill becomes a logged script instead of a rented subscription. Claims are claims. It goes on the list because the shape is right.
The one rule future me should keep: describe, do not stuff
Whichever of these I end up testing, the rule that decides whether a generator helps or harms is the same one Duda obeyed. Alt text exists for the reader who cannot see the image. Read the page through Lynx, the text browser, the way a screen reader's owner meets it, and listen: a description sounds like a description, and a stuffed alt, brand and keyword and slogan wrapped around a photograph of a man holding a wrench, sounds like a billboard in the wrong attribute. The titles and descriptions get the same discipline: around sixty characters for titles, around one hundred sixty for descriptions, the brand kept home on the home, about, and contact pages and out of the category pages, and no pipes, dashes, or em dashes as joinery in a title that should read like a sentence. Templates can hold some of that. The judgment cannot be set into a settings page, because no settings page knows the phrase a buyer types at midnight.
So the list stands, for my memory first and for anyone it helps second: Duda's generator, used and perfect; AltText.ai, Yoast Premium, SEOPress PRO, Rank Math's Content AI, and AI SEO Tools, listed on their claims and their prices, untested by me, awaiting the day a client job puts one of them in my hands. When that day comes, this post is where I will remember their names.
Update, November 12, 2026, 1056: the first version of this post carried the title "The AI SEO Tools I Actually Recommend" and review language implying I use and endorse these tools. I do not. I have used only Duda's built in alt text generator. The post has been rewritten as what it always should have been, a reference list for my own memory, with each tool's claims and prices labeled as claims and prices.
