EdTech
How to actually run a lesson on EdTechCore — build a course, write tasks that mark themselves, set homework, close the month. Short, no fluff.
EdTechCore is live
The clip got you here. This is the rest.
I’m Bobr. I build EdTechCore — the platform language schools run their actual lessons on — and I play a serious amount of Dota 2, World of Tanks and CS2. Every link in my bio lands right here.
No sign-up wall, no newsletter trap. Everything is one tap away.

Four things I post.
Follow the one you came for.
One channel, four very different moods. Nothing here is behind a paywall.
Dota 2
Ranked games, draft calls that looked clever for ninety seconds, and the occasional teamfight worth saving. Mostly the disasters.
World of Tanks
Replays, positioning that worked, positioning that very much did not, and the tanks I keep grinding long after it stops being rational.
CS2
Newest lane and the most honest one. Clips go up on the days the aim shows up. Some weeks that is a lot of clips. Some weeks it is not.

The lesson lives on the board.
One place for the whole lesson — a real-time board, tasks that check themselves, homework and grading — with the schedule and the accounts built around it. Four jobs that are normally four tools, four bills and four places the truth can differ.
One living canvas
A course is one board. Modules and lessons on a single canvas everyone sees change in real time.
Tasks that check themselves
A deterministic engine marks every task type — instant for the student, identical every time.
Homework and grading, one path
Assign to one student or a whole class. Only what genuinely needs a human ever reaches you.
Teaching and money, one system
The schedule you teach from feeds real double-entry accounting. Clean books, no spreadsheet.
Where to watch
Three channels.

Short-form goes to TikTok first, the long version lands on YouTube, and Instagram gets whatever happens between the two.

TikTok
The main stage. Everything starts here — platform tips in under a minute, gameplay, and the clips that send people to this page.
@bobrclub
YouTube
Where a sixty-second tip becomes the full walkthrough. Full EdTechCore tutorials, long replays, and anything that needs more than a minute.
@bobrclub
Stories, stills and the build-in-public side of shipping a product while also queuing for ranked. Less polish, more context.

Writing about what I’m building
Longer thoughts that do not fit in sixty seconds. Mostly about EdTechCore and the decisions behind it.
The task constructor: how building a lesson task went from an evening to a minute
Every teacher I spoke to had the same evening: the lesson is planned, and then the tasks have to be made, formatted and later marked by hand. Here is what we built instead — and the one rule we refuse to break about AI and grades.

About
One person, two jobs,
One person, two jobs,
zero free evenings.
I build software for people who teach, and I play games badly enough to be entertaining about it. Both end up on camera. If you found me through a thirty-second clip about a lesson board, that is the product. If you found me through a Dota clip, stay for the chaos — the product is still worth a look.

Pick one. Both are good.
Either you want the clips, or you want the thing the clips are about. There is no wrong door.
