My girlfriend (Spanish teacher) and I are in full lockdown atm (Colombia), so we started a blog project: https://triplechili.com. The idea is to find interesting content that's only available in English, and translate it to make it available in Spanish, while at the same time providing some tools for language learners. This came out of my own efforts to find content in both languages to help me learn Spanish. So we display posts in both languages and if you click on a sentence it highlights the same sentence in the other language. Right now it's just the boilerplate next.js + strapi (headless cms) that I found, but we're in the process of coming up with a proper design.
