A grammar profile that knows you, and an AI Tutor on every question
September 2026
This release rebuilds the heart of Learning. The grammar profile now works from evidence instead of a single counter, and two new AI companions sit on top of it: a Validator that grades what you write, and a Tutor that helps when you are stuck.
The grammar profile, rebuilt. Every rule shows its state (new, exploring, developing, secure), the evidence behind it and a recommended next step. A pace tracker counts real study minutes toward a weekly goal you can change or stop at any time. An activity log keeps your last week of grammar actions, with the result of each one a tap away. Trouble words, weekly goals and a delete-profile action live on the same page.
Check-ups in five languages. The free grammar check-up serves 16 items, two per focus rule, from hand-authored pools in German, English, French, Italian and Turkish. Retakes serve a different fixed form from your rotation. Every item was authored so each wrong option is wrong in every reading, and each explanation states only true grammar.
Rich Checkup. A paid, deeper check-up that generates items for your exact placement, follows up on what it finds and ends in a written report. It replaces the old deep check-up; sessions already in flight finish on the old path.
AI Validator. Written course answers can be graded by an AI Validator against the exact rules the course teaches, with a verdict, the rule evidence it saw and one actionable repair. In a Co-op room, one pass covers the room. It never grades what a deterministic check can settle for free.
AI Tutor. Press "I don't get this" on any question and the Tutor opens with that question loaded, or raise your hand from the corner launcher. It runs as a floating chat window or docked to the side, remembers your choice, and switches between the questions on screen without losing the thread. Answers come in the target language, your explanation language or both. Budgets are confirmed before anything is charged, and help you already received marks the item as assisted, honestly.
Follow-ups and reminders. Missed rules become follow-up opportunities with a due window, an optional reminder mail, and a re-arm button if you cancel one and change your mind.
Why am I seeing this? Small ? buttons across Learning explain every derived number in plain language, styled like every other tooltip and restylable with them. Rule pages link straight to their cheat-sheet entry.
Course lifecycle. A course untouched for a month is marked archived with a warning a week ahead. Nothing is deleted at that point and opening the course resets the clock; only another month of silence removes the content, and rebuilding it later is billed like a build.
Whole-credit prices. A course build is charged in whole credits, rounded up once at the total, exactly as the wizard displays it.
Your data. The profile page can export your Learning data as a ZIP, including your Tutor conversations, and deleting the profile removes what the export contains.
