Crawller

I need a crawler that could extract a text from a website for LLM learning, SEO Analysis and Brand Identity analysis. Other Crawlers couldn't do what I needed. So I built my own.

The crawler’s start screen, headed “Crawl a whole site.”, with https://carlosarias.com in the address field and a choice of three crawl methods: Sitemap, Follow links or Single page

Solo, architecture and build

The problem

Fetching pages is trivial. Turning a site into something a language model can reason over is not. Boilerplate has to go, structure has to survive, and the result has to be chunked in a way that keeps meaning intact across boundaries.

Most crawlers optimise for coverage. This one optimises for what comes after.

What it does

Large-scale collection with knowledge extraction built into the pipeline rather than bolted on afterwards. Output is indexed for retrieval, not just archived.

It is exposed to agents over MCP, so an agent can crawl and reason in one loop instead of waiting on a separate ingestion step.

Where it is

Running in production, feeding the other projects on this list.

Nova

2026 to present

The platform this site runs on. Nova is a team of AI agents that handles the repetitive work behind digital marketing, rank tracking, local SEO, citations, competitor research, content, QA, small site fixes, so that the hours I spend go to strategy instead. It runs my own projects and client websites in production.

Medellin.co

2022 to present

A city platform for travelers, expats and local businesses. It is where I learned RAG and autonomous content generation properly, at a scale where getting it wrong was visible.

Verificaa.com

2021 to present

ID verification and fraud prevention for Latin America. It exists because verifying who you are about to do business with is genuinely hard there, and that costs people real money.

Good marketing isn’t complicated. It just needs to be done right.

Strategy. Systems. Execution. Marketing that brings in cases and grows your firm.
