About AITag

A hand-curated directory of AI tools. Born in Brazil, operated from Europe, bilingual PT/EN. Built by people who actually use the tools, not just write about them.

What it is

AITag started as a personal spreadsheet. Every new AI tool that came out, I’d test it, note where it fit in my workflow, classify it by category. After a while the spreadsheet became internal reference, and it was clear it was worth opening up.

Today AITag is what that spreadsheet became: a public catalog of AI tools, with descriptions in both Portuguese and English, profile-based tags (visual creator, dev, podcaster, musician, educator), open-source filters and editorial curation.

Why Brazilian and European

Origin is Brazil. The editorial brain thinks about Portuguese-speakers: creators, devs, musicians, indie designers in Brazil and Portugal. That’s an audience rarely well-served by US directories (which ignore localization, language and context).

Operation is Europe. The European reading lives here too: tools that respect GDPR, open-source alternatives that escape the big-tech duopoly, projects based in Berlin, Paris, Lisbon, Amsterdam. AItag doesn’t turn a blind eye to that side.

No hype, no fluff

Not an automated leaderboard, not Product Hunt, not press-release coverage. Every tool goes through a human filter before entering. The description is mine, in two languages. The tags are the ones I’d use to find the tool again later.

Some links are affiliate, and that’s disclosed. But nobody pays to enter the catalog. Curation is not selling.

Ecosystem

AItag is part of Sapiens Sintéticos, an AI prototyping lab. The two share method, voice and backend (Convex), and overlap in places: tools that become articles in Coluna Sapiens, integrations with the editorial Pipeline.

How to suggest

Every tool page has a form. Or open it directly: suggestion form. If it passes the filters, it enters the next curation round.

FAQ

What is AITag?

AITag is a hand-curated directory of AI tools. Public website, bilingual (PT/EN), born in Brazil with an eye on Europe. Lists every tool we actually use, tested, or think someone else should know about.

Is it free?

Yes. The catalog is open, no required login, no paywall. Some listed tools include affiliate links, but that never determines whether they enter the catalog.

How does a tool get into the curation?

Real-world use first. We test it, classify it by category, describe it in PT and EN, and add profile tags (creators, devs, musicians, etc). Not a PR press release, not an automated leaderboard: it’s a selection made by people who build.

Why Brazilian and European?

Because that’s where we live and work. Brazil is the origin and editorial brain — built for Portuguese-speaking creators, Brazilian devs, indie makers. Europe is the operational base, with eyes on the European AI market, open-source alternatives, and GDPR-aware tools.

Who runs AITag?

AITag is part of the Sapiens Sintéticos ecosystem, an AI prototyping lab. Not a SaaS company, not an agency. It’s a living product, human-updated, in continuous alpha.

Can I suggest a tool or report a bug?

Yes please. There’s a suggestion form on every tool page, or open it directly: https://docs.google.com/forms/d/e/1FAIpQLScqs4r6bq2Rv2HO4dWUldYoPzgVTl9EqWgW3MkwW_1C4NPrhw/viewform .
