A tool to generate image alt-text, simple enough for anyone to use. From choosing the task to the decision pipeline, all the way to results that freed up dozens of hours for the team.
Generating alt-text was manual, slow and error-prone. High volume, strict rules and little creative room. A technical, repetitive job that ate into the UX Writing team's time. The ideal scenario for rules-based automation.

I picked a task with low creative need, high technical demand, repetitive and with room for human error due to volume. In other words, perfect for rules-based automation.
I used an enterprise AI assistant to help me build the agent, explaining in detail exactly what I wanted: an alt-text generator.
Describe only what is visible in the image. Use relevant details such as color, angle and scenario. Respect character limits. Recommended model: [angle/part] of the [brand model version], [color], [feature/part], [visible logos/text], [scenario].
It receives visual and contextual data (brand, model, angle, color, feature, scenario). Generates the ALT ordered by relevance, trimmed to 125 characters. Generates an informative, non-redundant TITLE. Generates the IMAGE NAME with technical normalization. Delivers everything in a single, standardized format.
A robust set of real, approved examples from automotive brands defines the style and serves as reference for the desired behavior.
I built it in one night and started using it the next day. I shared it with the team, who embraced the project right away. We kept improving it as needed.

A UX Writing professional reviews it
AI speeds up the mechanical part, but the final word always belongs to a person. The agent delivers a standardized draft and the team reviews it before publishing.

|---|---|---|
| 22 | 8h | 2h |
| 55 | 20h | 8h |
| 73 | 28h | 10h |
