How to use it

From download to first review.

01

Download the database

Grab dictionary-pt.db from the GitHub release below (about 114 MB). It's a standard SQLite file.

02

Open or query it

Open it in a SQLite browser, or read it from code. Inspect the tables to see the entry and sense schema.

Keep the attribution

Go further

Turn a word list into fluency.

A deck and a frequency list are a great start. Lector turns them into a full course — read real Portuguese with tap-to-translate, drill the same frequency-ordered words with cloze, and mine your own cards straight into Anki.
