This is an example of an agent your team can build in Sylvie: point it at your images and it writes accurate, accessible alt text that names your products correctly and reads in your brand's voice, across your site, catalog, social and email. It runs on your brand brain, so every description uses your real product names, your terminology and your accessibility rules, instead of the generic 'image of a person' that helps no one and wastes the SEO.
Sylvie does not ship this agent pre-built. It is an example of an agent your team can build with Sylvie, powered by your brand brain, so it runs your workflow the way you actually run it.
The Alt Text agent is an example of what a marketing team or agency can build in Sylvie: a workflow that writes alt text and image descriptions at the scale of a real content library. It knows your product names, your terminology and your accessibility standards, because it reads them from your brand brain rather than from a blank prompt. Sylvie does not ship it pre-built; you build it on the brain you already own.
Alt text is the task everyone agrees matters and nobody has time for, so it gets skipped, left blank or filled with a generic label that fails a screen reader and wastes the search value. An agent built for this clears the backlog and keeps new images covered, so accessibility stops being a someday project and every image ships described correctly.
You point the agent at the images: a new campaign set, a product catalog, a CMS library, a year of blog headers. It reads each image and pulls from your brand brain, the product names and facts, your terminology and house style, your accessibility guidelines and any keyword approach, all permission-aware so it describes with your real names rather than a guess.
Inside Sylvie it writes the alt text for each image: accurate, concise, screen-reader-friendly and on-brand, with longer descriptions where the context calls for them, cited to its source. You review, adjust the edge cases and push to your CMS or catalog, and new images get covered as they come in. Because you built the agent on your brain, it names the product correctly the first time, every time.
Years of undescribed images get covered in a fraction of the time a manual pass would take. The accessibility project that never gets staffed finally gets done.
The agent pulls your real product names, colors and terminology from the brand brain, so a screen reader hears the exact model and finish, not 'a shoe'. The description is genuinely useful, not a filler label.
Every image ships with alt text written to your accessibility standard, so your site moves toward WCAG conformance instead of failing an audit. Compliance stops being a risk you hope nobody checks.
Descriptive, keyword-aware alt text helps your visuals surface in image search instead of sitting invisible. You get discovery value out of a library you already paid to produce.
The same image is described the same way on the site, in the catalog, in social and in email. Your visual language stays coherent instead of varying by whoever happened to type the field.
Assemble it once and point it at each client's brand brain and image library. Every account gets alt text in its own terminology and product names, with nothing crossing between brands.
An alt text agent earns its keep anywhere images pile up faster than anyone can describe them: the catalog, the CMS, the campaign drop, the social calendar. Here is where teams point one they have built, and what it gives back.
A catalog of thousands of product images ships with empty or duplicate alt text. The agent writes accurate descriptions using the real product names and attributes from your brand brain, so the whole catalog becomes accessible and image-searchable in days, not a quarter of manual data entry.
An audit flags hundreds of images missing alt text ahead of a compliance deadline. The agent describes the full library to your accessibility standard, so the site clears the audit on time instead of the team hand-writing fields for weeks.
A campaign drops with dozens of new visuals that need alt text before they go live. The agent writes on-brand descriptions for the whole set in one pass, so the launch ships accessible on schedule rather than posting first and backfilling later.
Years of blog headers and in-article images sit with no alt text and no search value. The agent works through the backlog and covers new posts as they publish, so the content library starts earning image-search traffic instead of being dead weight.
Every send has images that render blank for anyone with images off or using a screen reader. The agent writes alt text tied to the email's message and your terminology, so the newsletter reads correctly for everyone and the offer still makes sense when the image does not load.
Each client has its own products, naming and visual style. One agent, pointed at each client's brand brain, describes every library in its own terminology, so the team keeps a whole roster accessible without learning each catalog by hand.
A generic captioner describes what it sees in generic words, so it writes 'a person holding a bottle' and gets your product name wrong. This agent is built on your brand brain, so it uses your real product names, terminology and style, and writes alt text that is accurate and useful instead of a caption you have to correct line by line.
It writes to the accessibility rules you set in the brand brain, following alt-text best practice: concise, meaningful, no redundant 'image of', with longer descriptions where the context calls for them. You define the standard you are held to, and the agent applies it to every image consistently.
No, and you do not buy it off the shelf either. Sylvie does not ship a ready-made Alt Text product; this page is an example of an agent your team assembles in Sylvie on your own products, terminology and publishing flow, so it describes images the way your brand actually talks about them.
Your brand brain holds your product names and facts, your terminology, your house style and your accessibility guidelines, all permission-aware. The agent reads from it for every image and cites what it used, so the description names the right product and matches the way you write about it.
That is the whole point of building it rather than buying it. You set the naming conventions, the tone, the length rules and the keyword approach, and as your product line and terminology evolve in the brain, the agent's descriptions move with them.
Each brand brain is isolated and permission-aware, so one client's product names and unreleased visuals never surface in another client's alt text. The agent only reads what it is allowed to, and you decide what it can see and where it writes.
