Best free platforms with certificates

Free platforms deliver basic certificates but do not offer enough speaking practice to develop fluency.

Kultivi offers free courses with certificates and focuses on theory, but does not include practical conversation. Aprenda Mais MEC provides free government content, but with an outdated and less intuitive interface. EF SET applies a free CEFR test to measure English proficiency, but does not offer a complete conversation practice path.

Best traditional paid platforms

Traditional platforms offer structured classes, but usually have fixed schedules, high costs, and depend on the individual quality of each teacher.

Open English offers live classes at different times, but charges high prices for a limited amount of conversation. Italki stands out in live conversation with native speakers in personalized 1-on-1 lessons, priced between US$ 3 and US$ 30 per lesson, though the total recurring cost can get high. Cambly connects students with natives, but the experience varies greatly depending on the chosen tutor.

Platforms with AI for fluent conversation

BeConfident uses AI to prioritize continuous conversation and daily practice. The platform already gathers over 200,000 paying students and 3 million users in more than 100 countries, with an RA 1000 rating on Reclame Aqui.

BeConfident offers a free test to identify your current level based on the CEFR standard, AI tutors with diverse personalities and accents—such as American, British, and South African—structured tracks combining theory and conversation practice, and conversations through audio, text, or simulated calls via the app, WhatsApp, or smartwatch.

CEFR certificates are globally recognized among employers, universities, and immigration authorities.

Features include personalized review of mistakes, Teacher Be to answer questions instantly, the "Tell me something new" command to expand vocabulary, and the My Evolution Menu with streaks, ranking, practice hours, and certificates.

Duolingo prioritizes gamified activities and maintaining streaks, which helps with consistency, but does not guarantee conversation fluency. BeConfident focuses on natural and frequent conversation in an environment free from public exposure. Compared to traditional human tutors, BeConfident offers total availability, consistent quality standards, and no scheduling limitations.
