juntosSpanish grammar courses, from the past tense to the subjunctive
Thirteen short courses covering the grammar that English speakers actually get wrong, each paired with AI conversation practice that grades every sentence.
These are the grammar courses inside Juntos, published here in full. Each one is a short sequence of lessons — the same material learners work through in the app — with conjugation tables, notes and a couple of exercises to try. They are ordered roughly by how often the topic shows up in the Error Bank of learners who use the AI tutor: the past tense and ser vs. estar first, because they are the mistakes that recur most.
Reading a course is the first half. The second half is using the grammar in conversation, where the Juntos AI tutor scores every message 0–100, corrects what you wrote and tracks the slips that keep coming back. If you already know which topic is yours, start there; if not, the past tense is where most English speakers get stuck.

How the courses connect to practice
Every course points to the practice scenarios where its grammar shows up most: the past tense in the traveller and emergency scenarios, ser vs. estar almost everywhere, the subjunctive and conditional in the friendly debate. Working a course and then running its scenario — in text or in AI Call voice mode — is the loop the app is built around, and the mistakes you make in the scenario feed back into what the app reviews with you next.
