We scored a Registro.br domain list for Brazilian name appeal, then built a free explorer. Here is what a decision model can help you see—and what still needs your judgment.

A good domain name can suggest a whole business. Finding it in a list of more than 157,000 names is another matter.

We gave a decision model a simple job: evaluate each name for its appeal to Brazilian buyers. The full scoring run covered **157,550 domains** and cost **US$0.87**, rounded, less than one dollar. The result is a searchable collection you can explore yourself.

## From a long list to a useful starting point

The source was a Registro.br list generated on **October 12, 2026**, for the **October 14–21, 2026** release period. It is a snapshot of a particular process, not a live inventory of names you can register today. The [official Registro.br release-process page](https://registro.br/dominio/processo-de-liberacao/) explains how that process works.

We used **Clef Flash through OpenRouter** to score the names on a **0–100 scale of relative name appeal**. A decision model answers a focused question with a structured judgment, such as a category or score. That full-run cost excludes the earlier pilot experiments.

What makes a name appealing? We asked the model to consider clarity in Portuguese, commercial purpose, the range of plausible buyers, memorability, spelling and how well the extension fits. The Brazilian market was the focus, with a preference for `.com.br`. Awkward strings, very narrow uses and apparent brand-specific names counted against a domain.

## What the names reveal

Near the top, `mentoria.com.br` scored **91.9**, `sustentavel.com.br` **91.2**, and `botica.com.br` **88.8**, rounded here for readability. These examples point toward something practical: a recognizable word can give a reader an immediate sense of a service, a theme or a shop.

That is a useful lens, but it is still a lens. Your best name may be a specialist term that means everything to a small audience. A broader name may score well and still be wrong for your product. The ranking helps decide where to look first; it cannot choose your positioning for you.

## Try a search around your next idea

Start with a word related to your business. Search for `saude`, `loja` or `educacao`, then raise the minimum score. If brevity matters, set a maximum length or sort by the shortest names. Length includes the dots and extension.

Search ignores case and accents, so `saúde` also finds `saude`. Read the candidates aloud. Imagine saying the name over the phone. Ask whether someone would remember how to spell it tomorrow.

The score is **not a resale-price estimate, a trademark clearance or an availability check**. Before acting on a name, check its current status and any rights that may apply.

## A small example of a bigger idea

Here, the model's value was making a large collection easier to navigate. The same approach could help prioritize a catalog, sort incoming leads or identify documents worth closer attention.
