So, to be above board, these guys do offer referral codes, and I'm not posting one here. I really just want to let you know about how it saved me a bunch of time today.
We're updating a client's large, old, public-policy (WordPress) site. They have a very large image library and none of the images had alt tags added when they were created. In the past, we've used a spreadsheet view plugin and hand-entered alt tag descriptions, but this would have been untenable here.
I had tried AltText.ai on a smaller site in the past and found it to be adequate at describing the images to ADA requirements, but this site has a lot of charts, infographics, and complex images. I didn't want alt texts that were like "a chart" or "a photo of a man in a red hat". The client would not be satisfied with it.
I believe the service works with non-WP platforms, but I was using it specifically with their WordPress plugin. What's interesting is that (maybe this is new, or maybe I didn't see it before) it has the ability to query what web page an image is utilized in, and then presumably uses the existing textual context of that page to infer more meaning about the image it's trying to text summarize. I'm imagining it must be using some kind of multimodal LLM to do this analysis because it's way beyond what I've seen from machine learning image-to-text tools using something like the CLIP or BLIP models.
I'm not going to post specific exact text it created for me, but as an example, one image was a busy, full-page infographic. Instead of "a large infographic" it wrote something like
Infographic on the [topic] in [region], outlining average [metric], reasons for [condition], cost breakdown, and [adjective] challenges.
For a chart that was generated in Excel it wrote
Scatter plot depicting the total [metric] as a percentage of net assets in [policy name], with the solid line representing median [metric].
Honestly, this is WAY better than I had any right to expect.
There are also controls for adding positive and negative keyword suggestions for SEO purposes.
I hope this tool saves you guys as much time as it saved me. There may be competitors, and they may even be better, and if so, please tell me. But for the moment I'm super happy with the results I got from this one, as I don't want to think about how I'd have done it without. They offer 25 free image convert credits on a new account, and if you pass it along to your friends they DO have a referral code you can use that gets you AND them 50 free credits. I am not posting my code here, for full objectivity.
