The only purpose-built
European Portuguese support dataset — Commercial Licence
Most "Portuguese" instruction datasets are actually Brazilian Portuguese. LusoSupport-PT — European Portuguese Customer Support Dataset (Commercial Licence) is written exclusively in pt-PT — validated, structured, and ready to fine-tune. This licence covers commercial software, SaaS APIs, and client/consulting deliverables.
"instruction": "Classifica a intenção principal do cliente e responde apenas com um objeto JSON."
"input": "Bom dia, preciso da fatura referente ao pagamento deste mês."
"output": {"intent": "invoice_request",
"urgency": "low",
"domain": "billing_accounts"}8

pt-PT ≠pt-BR
Vocabulary, verb conjugation, and register genuinely diverge. Models trained on pt-BR data reliably produce phrasing that reads as wrong to a Portugal-based audience — every row here is checked against it.

Who this is built for
This Commercial Licence is for teams shipping revenue-generating products, SaaS APIs, or paid client deliverables. If any of these sound like you, the dataset pays for itself the first time you use it.
SaaS & e-commerce teams serving Portugal
Fine-tune a support model or copilot that replies in real pt-PT — telemóvel, palavra-passe, fatura — instead of Brazilian phrasing that reads as foreign to your customers.
Agencies & freelance ML consultants
Skip weeks of manual data collection for a client's Portuguese support-automation project — 10,828 ready-labelled rows across 8 business domains, licensed for commercial fine-tuning.
Chatbot & helpdesk copilot builders
Bootstrap intent detection, urgency triage, and next-action suggestion for a support bot without hand-labelling a single ticket.
Researchers & NLP practitioners
Benchmark pt-PT generation quality, run few-shot prompting experiments, or evaluate variant drift (pt-PT vs. pt-BR) with a clean, richly annotated reference set.
Enterprises with a Portugal support desk
Use `rewrite_professional` rows to train a tone-consistency layer so every agent's reply — regardless of who typed it — reads polished and on-brand.
Indie devs building RAG support tools
Index approved rows as a retrieval corpus so a general-purpose LLM answers in grounded, on-tone pt-PT — no fine-tuning required.
Integrate in minutes
Load it with the tools you already use — no custom parsing.

Questions
Is this really pt-PT and not pt-BR?
Yes. Every row runs through an automated validator that rejects banned pt-BR vocabulary (celular, senha, nota fiscal, etc.) and confirms the pt-PT variant tag before release.
What's the licence?
This is the Commercial Licence: it covers use in commercial software, SaaS APIs, client/consulting deliverables, and team or organisation-wide use — not just personal/research use. Need only personal or research use? The cheaper Individual Licence is also available on Gumroad.
Can I try before buying?
Yes — a free 200-row sample covering all domains and task types is on Hugging Face under CC BY 4.0.
Do I get future updates?
Yes, all future v1.x releases (more rows, more domains, harder edge cases) are included at no extra cost. v1.1 already shipped: rows doubled from 5,162 to 10,828 with no price change for existing buyers.
