Explicacoes.com
A large-scale Portuguese learning platform — search, a tutor marketplace and an AI-powered tutor, with 25 years in operation.
A learning ecosystem at scale
Founded in 2001, Explicacoes.com connects students at every level of education with verified tutors, backed by its own exercise database and an AI tutor that searches that database before responding.
Three pillars of the platform
Exercise library
Thousands of freely accessible exercises organised by subject and level, forming the knowledge base for the whole platform.
Tutor marketplace
Search and filtering by subject, location, price, ratings and format (online or in person), with direct contact between student and tutor — no intermediaries.
AI tutor
Before generating a personalised explanation, the tutor first searches a database of over 6,700 exercises — answers grounded in the platform's own content, not generated from scratch.
International reach
International tutoring and PhD support extend the platform beyond primary and secondary education.
