I used to write journal entries in Portuguese every morning, then paste them into ChatGPT with a carefully crafted prompt to get corrections and coaching feedback. The practice worked incredibly well โ€” better than any app or class I'd tried โ€” but the workflow was held together with duct tape. So I built Bonjournal to remove the friction. Write in your target language, hit submit, and get back a corrected version with detailed explanations, progress scores for grammar, vocabulary, and verb usage, and coaching that actually responds to what you wrote. Track your streak and watch yourself improve over time. Supports 10 languages. Free to start. Built for language learners who want to actually use the language, not just study it.
