What's New

Writing feedback, one click away

Every self-assessed writing exercise in the course now has an Ask AI button. Pick your model and:

• No MCP connected: opens the exercise + your draft in ChatGPT, Claude, or Gemini in a new tab
• MCP connected: the writing is shadowed to your writing_submissions, so any connected AI client can grade it with full context (your level, prior mistakes, the lesson topic)

Your preferred provider is remembered across the site.

Stop drilling things you already know

Six drill pages — verbs, articles, adjectives, cases, prepositions, and word order — now have a Practice weak spots button next to the start CTA.

Click it and the next session is built from your own mistake history: the words you've missed, the cases you keep flipping, the verbs you can't conjugate. Mistakes from in-course exercises and AI sessions both feed the pool, so the longer you use the app, the sharper the weak-spot session gets.

Practice without the friction

The drill experience has been rebuilt from the ground up.

• Every /practice/* drill is now a continuous 20-question session, not a one-shot question
• Press Enter to check, then Enter again to continue — no mouse needed
• Wrong answers reveal the correct answer inline and auto-advance after a short pause
• Multiple-choice questions let you retry once before showing the answer
• Hints (including noun gender) appear inline for preposition and adjective drills
• A unified ChoiceAnswerButton and TextAnswerQuestion primitive means every drill behaves the same way

Under the hood, this is the unification of nine separate drill components onto one renderer pipeline, and the introduction of the MultiQuestionFrame host that powers session flow.

Make the grammar reference your own

The entire grammar reference is now yours to mark up.

• Fork any system grammar page and edit your copy — examples, tables, your own mnemonic
• Annotate any section with a sticky note (question, reminder, mistake-you-keep-making)
• Annotations are anchored to specific blocks, so they stay attached as the page evolves
• Connected AI clients can read, write, and update grammar pages and annotations via MCP — useful for "explain this section in simpler terms and save it as my version"

A plan, not just a pile of exercises

Tell the system (or your connected AI client) what you want to focus on this week — passive voice, Konjunktiv II, job interview vocab — and you get a structured multi-day plan back.

• Each day has its own items: a reading, a practice session, a grammar page to revisit
• Items can be marked done as you complete them
• Practice-session items deep-link to a real, generated session
• Plans can be revised mid-flight as your needs shift

Did you actually understand it?

Every reading now ends with an interactive comprehension quiz. Three exercise types are supported:

• True / False — fact-check claims about the text
• Multiple choice — single-answer questions on key passages
• Matching — pair speakers, events, or ideas with descriptions

Questions are typed and validated against a schema so the renderer always knows how to display them, even on older readings.

A notebook that writes itself

The new Error Notebook (Notebook in the sidebar) turns the noise of "you got this wrong" into a structured journal you can actually study from.

• Mistakes are tagged with concept tags (e.g. dative prepositions, separable verb position)
• Curated entries explain the pattern, not just the one slip
• Each entry cites the specific mistakes it's built from
• You can also add manual notes — entries don't have to be auto-generated
• Connected AI clients can read, write, and link entries via MCP

Practice that actually targets your gaps

Instead of always practising every drill, you can now ask the system (or a connected AI client) to generate a practice session for you.

• Pulled from your recent mistakes, weak words, and uncovered grammar
• Mixed exercise types — MCQ, gap-fill, ordering, typed answers
• First-attempt-wrong answers feed back into your mistakes log for tomorrow
• Sessions are saved and resumable

Reading practice that meets you where you are

Generate short German texts targeted to your current level. Every word is interactive:

• Click any word for an instant gloss with translation, IPA, and example sentence
• Glosses are persisted so the reading remembers what you've already looked up
• New vocabulary can be queued straight to your spaced-repetition deck
• Connected AI clients can fetch, glossify, and follow up on any reading

Write. Submit. Improve.

The new Writing workflow lets you submit anything you've written in German and receive structured feedback graded against your current level.

• Submissions are saved to your account
• Feedback covers grammar, word choice, register, and structure
• Connected AI clients (via MCP) can read prior submissions and follow up
• In-course writing exercises now shadow-write to the same store, so MCP can grade them too

Bring your own AI tutor

One Who Learns now ships an MCP (Model Context Protocol) server. Connect Claude Desktop, ChatGPT desktop, or any MCP-compatible client and the assistant can see what you already know, what you got wrong, what you're reading, and what you're studying — without you copy-pasting context.

Tools the connected AI can call on your behalf:

• Look up and add words to your vocabulary
• Read your recent mistakes and practice sessions
• Generate readings, exercises, and study plans
• Open and edit your grammar pages and journal
