Instructor Learnimu
The shift into formal Japanese — written news, business email, academic prose, and essay-style speech. By the end you will be able to: Use the formal scope and circumstance patterns — にあって, をめぐって, にわたって, にかけて, を契機に, を皮切りに, を経て, を機に, における, をもって, にて. Express contrast and limitation with にしろ・にせよ, どころか, ながらも, ものの, にもかかわらず, 一方で, 反面, に反して, ことなく, にすぎない, にひきかえ. Pin down cause and concession at the N2 level — あげく, 末に, につき, 以上は, からこそ, からといって, だけに, とあって, ことから, ゆえに. Mark time and circumstance precisely — が早いか, や否や, 矢先に, かたわら, がてら, につけ, ところを, かぎり, ぬきで, かたがた, かと思いきや. Reach for the literary set-phrases the JLPT loves — ずにはいられない, にこしたことはない, かのよう, までもない, ばこそ, たるもの, しまつだ, ともなれば, あっての. How the course is taught. Same Nihongo So-Matome / Tobira shape — quick meaning, formation, two examples, a nuance note that contrasts the pattern with its closest neighbour, and a one-line pitfall. Reading aids. Furigana parentheses appear only on rare or unusual readings. Pattern names are bare Japanese — by N2 you read at speed.
JLPT N1 Grammar
Instructor Learnimu
The summit of JLPT grammar — literary inversions, classical particles, idiomatic constructions, and the formal Sino-Japanese phrases of newspapers, court rulings, and literary essays. By the end you will be able to: Use the sophisticated scope and circumstance markers — にとどまらず, もさることながら, とあいまって, をふまえて, をよそに, をものともせず, をおいて, にいたっては, にいたるまで. Read and use literary inversions — んばかりに, べく, べくして, べくもない, まじき, (よ)うが, (よ)うと, (よ)うものなら, たりとも, ずとも, なり. Understand set Sino-Japanese constructions — ともすれば, までだ, ものを, かぎりだ, ことか, だらけ, ずくめ. Reach for advanced concession and emphasis — とはいえ, にしたところで, といえども, であれ, ばそれまでだ, ばまだしも, からには, を限りに. Master the idiomatic two-part patterns — やら〜やら, だの〜だの, といい〜といい, といわず〜といわず, ずにはおかない, を余儀なくされる. How the course is taught. Same Nihongo So-Matome / Shin Kanzen pattern — quick meaning, formation, two examples, a nuance note that contrasts the pattern with its closest neighbour, and a one-line pitfall. Reading aids. Furigana parentheses appear only on rare or unusual readings. By N1 you read at full speed; the goal here is to recognise patterns by shape, not to look up kanji.
Building with AI APIs
Instructor Learnimu
Take your first practical steps building with LLM APIs in Python. By the end of this course you will be able to: (1) make authenticated API calls and read pricing/rate limits, (2) get reliable structured output and use tool calling, (3) build a small RAG pipeline with embeddings and a vector store, and (4) ship a prototype that handles costs, errors, and basic observability. Light Python is used throughout — copy-paste-runnable, no prior LLM API experience required.
Basic AI Knowledge
Instructor Learnimu
A beginner-friendly introduction to artificial intelligence and how it works in everyday life. By the end of this course you will be able to: (1) explain what AI is and how it differs from machine learning and deep learning, (2) describe how AI learns from data and where it struggles, (3) recognise AI at home and at work, and (4) write clear prompts to get useful results from AI assistants.
AI Safety, Ethics & Governance
Instructor Learnimu
The strategic, organisational, and ethical layer that turns an AI capability into a responsibly-deployed product. By the end of this course you will be able to: (1) reason about bias, privacy, and copyright in AI systems, (2) write and operate an AI policy that fits your organisation, (3) run pre-launch risk reviews and incident responses, and (4) build a culture where responsible AI use is the easy path, not the heroic one.
AI in Your Workflow
Instructor Learnimu
Move beyond "asking ChatGPT for help" to a practical, repeatable way of weaving AI into research, writing, and decision-making. By the end of this course you will be able to: (1) learn a new topic faster without losing depth, (2) write and edit with AI without surrendering your voice, (3) use AI to think through hard decisions and trade-offs, and (4) protect yourself from the failures that creep in when AI quietly does too much of the thinking.
AI Agents & Automation
Instructor Learnimu
Move beyond single-shot prompts to autonomous, multi-step agents. By the end of this course you will be able to: (1) explain what an agent is and where it differs from a chatbot, (2) build single-tool and multi-tool agents with planning and memory, (3) measure agent quality with evals and protect production systems with guardrails, and (4) decide soberly when an agent is the right architecture and when it isn't.
