2021NeuralShift is a Portuguese AI company that builds Affine, an AI-powered legal research platform for law firms and legal departments.
Affine differentiates from global legal AI tools like Harvey and vLex by focusing narrowly on the Portuguese and Spanish legal markets. It combines public legal databases with firms internal know-how to win on local specialization, language, and integration with Portuguese legal workflows.
Its native AI build is optimized for Portuguese jurisprudence, offering deep understanding of amendments, hierarchies, and cross-references that generalist platforms often miss. This regional focus allows Affine to deliver more accurate and contextually relevant results for Iberian legal professionals.

Affine sells to law firms, corporate legal departments, and public institutions through a demo-led motion: the site routes buyers to a "Book a demo" flow with sales follow-up rather than self-serve checkout, supported by client references across Portuguese law firms such as VdA, SRS Legal, and Raposo Subtil Associados, plus public bodies including the Tribunal de Contas and Instituto Superior Técnico.
Its acquisition channels are direct sales and institutional relationships: the team presents at legal-technology events such as LegalTechTalk in London, and industry relationships bring referrals — its pre-seed investors, CTT's 1520 program and Iberis Capital, publish the investment in their startup-program news.
Affine is an AI legal research platform built for legal professionals across Europe. It connects legislation, case law, and everything an organization already knows. It provides semantic search, internal knowledge indexing, transcription, AI legal reasoning, batch analysis, legislative monitoring, drafting and translation, source verification, jurisdiction comparison, and API integration.
Coverage includes Portugal, Spain, and EU sources such as EUR-Lex, UPC, and EDPB. Affine serves 100+ organizations and 1,000+ lawyers monthly, developed by NeuralShift, a Portuguese AI startup spun off from INESC-ID and Instituto Superior Tecnico in 2021.
