Edubrain is an AI-powered academic writing and homework assistance platform for students, with the page title “IA para Trabalhos Acadêmicos.” Users can enter a topic, paste a question, or upload drafts, outlines, notes, and files, then have the system generate or improve academic papers. It covers a wide range of subjects, from math, physics, chemistry, biology, and history to programming, finance, law, nursing, and more.
Its core feature is essay/paper generation: users can choose a tone or writing level and generate structured, clear text with images and citations. Beyond writing, it also offers an AI answer generator, AI detector, chart generation, flashcard generation, note generation, PowerPoint generation, humanized rewriting, and plagiarism checking. Input methods include text, file upload, and audio recording. The page lists the following limits: up to 10000 characters for text, 25MB for audio, 32MB for AI files, support for txt/pdf/doc/png/jpeg/jpg, and only one AI file allowed.
The FAQ says the essay generator is 100% free, with no hidden fees and no registration or email required. However, the page also shows a Premium subscription at $3.99/week, down from $16, which includes unlimited homework help across all subjects, faster responses, no ads, A+ quality answers, advanced reasoning, answer sharing, and discounts on expert assistance. PowerPoint generation is free up to 5 slides; a full presentation requires a subscription.
Its strengths are a low barrier to entry, broad subject coverage, and a toolset that fits the full learning workflow. Its privacy statement is also relatively clear, saying it does not store personal data or uploaded content and deletes sessions after they end. The limitations are that it does not disclose the underlying model, citation sources, fact-checking methods, or API integration options. Claims such as “reliable citations” and “A+ quality” are not backed by examples. The official site also positions it for brainstorming and structuring, and recommends human review before submission; users still need to manage academic integrity risks themselves.
It is better suited to students in Portuguese-speaking environments who need first drafts, homework ideas, classroom materials, and presentations. Chinese-language support is not mentioned, so it is not recommended as a first-choice tool for Chinese academic writing. Its accessibility from mainland China is unknown, and payment methods are not disclosed. If access or payment is restricted, alternatives include ChatGPT, Claude, Perplexity, or China-based tools such as Kimi, 文心一言, and 秘塔写作猫.
