Portugal Tools Hub
Portugal Tools Hub is a comprehensive utility platform designed to simplify the financial and bureaucratic aspects of living and working in Portugal, catering to both locals and expats.
Key Features
Financial & Tax Calculators
Includes highly accurate tools to calculate net salary (factoring in IRS and Social Security), estimate municipal property taxes (IMI), and plan for retirement.
Bureaucracy Management
Features a real-time NIF (tax identification number) validator and an interactive Tax Calendar to help users track important Portuguese tax deadlines and VAT obligations.
Open Source Contributions
We are committed to advancing AI for the Portuguese language. Our team has built and published several key datasets, including 'portuguese-ocr-dataset' and 'portugues_ocr_dataset_full', which are widely used by the community to train AI models for reading Portuguese text.
Model Fine-Tuning
To improve document digitization, we actively fine-tune TrOCR (Transformer-based Optical Character Recognition) models. We have released multiple versions of 0.3B parameter models, specifically optimized to accurately extract and read Portuguese text from images.
Applied AI Research
We rigorously experiment with cutting-edge technologies. Our 'Spaces' such as Alpaca-LoRA and Banks demonstrate our expertise in fine-tuning Large Language Models (LLMs) using Low-Rank Adaptation (LoRA) and building robust AI applications.
