Is it for someone like you?
Five ways people use Hakken. Each one opens with what a real learner said, and closes with a real course built for them.
01
Cramming for an exam
Six weeks out. The textbook starts at chapter one
“Stats final in six weeks. I get regression; ANOVA is where I fall apart. I can do maybe four hours a week, and I don't need the history of statistics.”
What Hakken does with that
Sized to the weeks you have
Backward from your exam date. The interview asks when and what's tested. No chapters you won't see.
A checkpoint per module, and a review lesson when you miss
Miss a checkpoint, get a fix. Hakken writes a short lesson on exactly what tripped you, then lets you retake.
Ask when it goes too fast
Say the word, get a gentler ramp. Type it, or talk to the tutor mid-lesson. Hakken proposes a real change to the course — not just an answer.

Learning for a trip
You don't need Japanese. You need lift-line Japanese by February
“Snowboarding in Hokkaido for ten days. I want to order food, ask for help on the mountain, and not be the tourist pointing at things. I've got a couple of hours a week and a long flight.”
What Hakken does with that
Built around the situations, not the grammar
Your trip is the syllabus. Izakaya orders, lift tickets, the onsen question you're too shy to ask — modules follow the days in order.
Phrases you can hear, slow down, and try out loud
Hear it. Slow it. Say it back. Lessons speak the hard phrases. Talk back to a tutor that follows you into Japanese.
An episode for the flight
One module, one podcast. Turn any module into a two-host episode — made for a plane with no wifi.

Picking up a skill for work
You already code. You don't need 'what is a variable' again
“Ten years of Python and Node, moving onto a Rust backend team next quarter. I understand HTTP and databases cold — it's ownership and lifetimes I need, fast, with real API code.”
What Hakken does with that
Pitched at what you already know
Starts where you actually are. The interview maps your level. What you know gets a paragraph, not a module.
Worked examples and exercises you'd meet on the job
Real code, real feedback. Exercises from the work you're moving to, marked with feedback and a copy button on every snippet.
Add the missing lesson
Missing a topic? Ask. Type it, or say it mid-lesson. Hakken proposes the insert; you approve, the course changes.

Prepping for an interview
Your data science is solid. Explaining it live, in English, is the gap
“I can build the model. I freeze explaining my thought process out loud in English, especially when they interrupt with a follow-up. My onsite's in three weeks.”
What Hakken does with that
Built around your actual round
Your interview loop is the syllabus. Take-home walkthrough, live coding, stakeholder Q&A — say what's on your loop, and the course becomes English for exactly that.
Practice out loud, not silently
Talk to a tutor that talks back. Say your answers by voice. It interrupts and follows up, the way a real interviewer does.
Sharpens the answer that stalls you
Flag the freeze, fix the freeze. Name the moment you went blank, mid-lesson, and Hakken adds a short lesson on that exact phrasing before your next mock round.

Learning for the love of it
An hour on Sunday, and no course that wastes it
“I've wanted to knit for years. Complete beginner, an hour or so on Sunday evenings, and I'd like to finish something I'd actually wear rather than a hundred practice swatches.”
What Hakken does with that
Paced to the hour you have
One Sunday hour, respected. The outline fits your rhythm, project by project — never a bootcamp squeezed into an hour.
Shown, not just told
See the stitch, not just read it. Diagrams and images made for your course sit right beside the words.
Keeps going after the first pass
Doesn't stop at lesson one. Podcasts for the commute, review lessons when you slip, a tutor for the question you'd never type.

None of these, exactly? Good.
Nobody's goal fits a category. The interview asks about yours, and builds from there. See what's in a course.
