About Vizibly

Machines still need words to understand your images

Modern engines can look at a picture — but they still lean on words to understand it, file it, and connect it to the rest of the web. Vizibly makes sure those words are there for every image on your site.

The problem

Most images ship without the words machines rely on

In its 2026 survey of the top one million home pages, WebAIM found that over half had images with missing alternative text (WebAIM, 2026). No alt text, often no descriptive filename, no structured data — nothing for a search engine or an AI model to hold onto.

When that context is missing, engines are left to guess what an image shows — and often can't index it meaningfully. Vizibly closes that gap: it audits every image on a page, scores it on SEO and GEO signals, and generates the alt text, captions, schema, and LLMs.txt entry it's missing.

The story

Built in the open, by one person

Vizibly is built after hours, alongside a full-time job. No team, no office, no outside funding. Just a 15-day build-and-ship challenge, documented daily on X (@theyole_).

Principles

The principles behind every audit and optimization

Transparency

Transparency first

Every score is explainable — and the copy on this site is held to the same bar. When the compression demo was measured, the number was corrected downward. That's the policy working.

Performance

Speed matters

Full page audits in under 60 seconds. AI metadata generation in one click. No waiting around.

Privacy

Your data stays yours

Scans are read-only — your site is never modified. The audit results and images you upload are stored so you can optimize them, and you can delete them anytime.
