Checkmate Mind

The chess platform your academy runs on.

Bring your classes, your coaches, your students and their parents. Every game is reviewed, every student's record is kept, and a parent can tell whether it is working. Players without an academy are welcome too.

Game analyzer · even paper scoresheets

Photograph a scoresheet or paste a game. I read what actually happened, scribbles and all, and find what it was trying to teach.

Analysed

Move 13 was scribbled over. Worked out from the position.

One missed fork found. Eight practice positions added.

The placement · twelve positions

About six minutes, no payment, and we know your rung on the ladder and what to practise first.

Take the assessment
Self-paced circles · a coach can join later

Your practice lives in a circle. Work on your own, let a parent look in, or bring a coach when you are ready.

Coach: bring the forks to Friday's class. The bot will test them first.
Sparring bot · plays at 1200 today

She missed a couple of forks at the tournament last week. So this game, let me leave one and see if she finds this fork.

I will keep a lookout for new weaknesses and strengths. Otherwise I play my honest 1200.

Who it is for

One platform. An academy, its coaches, its students, their parents.

Checkmate Mind is not one academy. It is the place an academy runs: the classes, the coaching, the practice between lessons, and the record of every student, with the people around that student each seeing what they need.

♛

Academies

Each class is a circle with its coach, its students, and their parents. Enrolment, schedules, meeting links, placement on the eight-level ladder, and a record per student that stays with the academy's history. Your own name and colours on it, your fees collected for you, and one admin page for the whole academy.

♞

Coaches

Open a student's record and see what was taught, what stuck, and what keeps coming back. Every game they played since the last lesson, already reviewed, with the student's own notes on what they were thinking.

♟

Students

Puzzles from their own games, a sparring bot that plays into their weak spots on purpose, a coach's recap after every set, and whole games from a photographed scoresheet.

♡

Parents

Plain words about what their child is working on and one question to ask, no chess knowledge needed, and a short email every week. Never a pile of engine numbers.

Running an academy? You bring the coaching; the platform brings the classes, the practice between lessons, the record of every student, the parent page, your branding, your billing, and an admin page for the whole academy. Start your academy: your desk opens straight away, and your families can join as soon as we have approved it.

On your own? The same platform, without the academy. Take the placement, practise, play the bots, and bring a coach or a parent in whenever you like. Nothing is lost if an academy comes later.

How this differs

What happens between the lessons

Most of what a chess student does happens when nobody is watching. The games, the puzzles, the losses nobody explained. Here is what we do with all of that, next to how it usually works.

We find the gap from the games you actually played You drill it as positions, not paragraphs A coach teaches it in small groups or 1:1 Parents can tell whether it worked

How it works

One continuous loop, not disconnected lessons

An academy usually runs on a lesson, a coach, and occasional homework. On Checkmate Mind the academy's classes, coaches, students and parents share one loop, so nothing a student does is wasted and every lesson starts with the coach already knowing what happened since the last one.

01

Learn

A live class or 1:1 lesson with a coach who knows exactly where you are.

02

Play

Online games, club games, tournaments, even a handwritten scoresheet.

03

Analyse

Every game reviewed for tactics, structure, and the decisions behind the moves.

04

Practice

Your mistakes become your puzzles. Then a training game quietly checks the fix holds.

05

Improve

Progress feeds the next lesson plan, for you, your coach, and your parents.

Sparring

The bot plays into your weakness. On purpose.

A puzzle tells you there is something to find before you even start looking. A real game gives no warning. So when practice says a weakness is fixed, the last step is a game that quietly tests it.

  • 1We spot the pattern. Say you keep missing knight forks in puzzles, in your online games, and on tournament scoresheets.
  • 2You are told one thing. Play. The game opens in a position where the idea is alive, and the bot plays on like any opponent.
  • 3It gives you a chance, on purpose. Every few moves it plays a slightly worse move, without telling you, so the fork is there to be found.
  • 4Seen or missed, it counts. The same detector that reviews your games judges the moment, and the result goes to your record and your coach.

Trainers that serve puzzles at your weaknesses exist, and they are good. We have not found another one whose bot plays a whole game and concedes, unannounced, to make the weakness appear. A strong coach does this over the board. That is who we learned it from. How sparring works, for parents →

Training game · what the student sees
♞ Move 12 · a chance appears The bot conceded a little to leave a fork on d4. Nothing was said. missed
♞ Move 19 · another one Ne5 forks queen and rook. This time you played it. seen ✓
◎ After the game 2 of 3 chances seen. The missed one is now a position in your practice set.
✎ The coach's recap “The fork on move 12 was the same shape as Tuesday's puzzle. You know this one.”

Why it works

Human coaching plus your own chess data

The AI is not here to replace a coach. It is here to give the coach better information and give the student better practice between lessons.

♞

Explained at your level

A beginner is told to check what can be captured for free. A 1900 is shown the overloaded queen. Same engine, different teaching.

◎

Mistakes become puzzles

The tactic you missed on Tuesday is the position you drill on Thursday. From your game, not a database.

↗

Patterns, not one-offs

The system remembers. Recurring weaknesses surface on their own, whether that is knight forks, rook endgames, or moving too fast when winning.

✓

Parents can actually tell

No evaluations, no notation. Plain language about what your child learned, what they are working on, and whether it is improving.

Circles

The shared space where the work actually happens

A circle is where the work lives. For an academy, a class is a circle: its coach, its students, and their parents looking in. For a player on their own, a private circle, where a parent or a coach can join later. Friends and classmates share group circles to play and compete together.

  • 1Upload anything. A PGN, a photo of a handwritten scoresheet, a page of class notes, a past paper. It gets read, reconstructed, and made useful.
  • 2Record what you were thinking. Note your reasoning move by move, so the review can coach the gap between your plan and the position.
  • 3Get quizzed on your own material. Not a generic question bank. The actual content you uploaded, at three levels of difficulty.
  • 4Coaches and parents read and guide. They see the roll-up and what to work on next. They are never on the leaderboard.

One record

Your learning history belongs to you, not to your coach.

A chess education usually lives in pieces. A coach's notebook, two chess websites, a drawer of scoresheets, a parent's memory of what the last coach said. Change coaches and most of it is gone. Here, the coach and the AI write to the same student record, and the record moves with the student.

  • ✓Everything lands in one place. Lessons, placement, per-move notes in the student's own words, the AI coach's recaps, every game from every source.
  • ✓Coached or self-paced, it keeps going. Pause coaching for a summer, study alone, come back. The record never noticed you left.
  • ✓A new coach inherits understanding, not a rating. They open the record and see what was taught, what stuck, and what kept coming back.
One student · one year
♛ February Coach teaches the opposition. Noted on the record.
↗ March It keeps failing in real games. Six positions assigned; five solved.
◎ May Coach moves away. The record stays.
♞ June – August A self-paced summer of puzzles, sparring games, and the AI coach.
✎ September A new coach opens the same record and starts from what is left, not from the beginning.

The software

The things a coach cannot do at 11pm

Coaches teach. The software does the parts that are tedious, repetitive, or need to happen between lessons. A few of these are heavy enough to be Pro.

Pro
♛

Photograph a scoresheet. Get the game.

Tournament games live on paper, in a child's handwriting, half of it wrong. Take a photo and we read it, then work out what the moves must have been by testing them against the position. A misspelt move that is illegal has only one legal neighbour, and that is the one you played.

What you wrote
1.e4e5 2.Nf3NC6 3.Bb5a6 4.B94Nf6

What we give back

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6

Every move it corrected is shown as "you wrote B94, read as Ba4", so nothing is quietly changed behind your back. Validated on real tournament scoresheets.

A note from Iniya

I have played and studied chess for eight years. I built this because I kept losing the same way and nobody could tell me. My games were on paper, my lessons were in someone else's notebook, and the two never met. So I made the thing I wanted. A place where the games, the mistakes and the coaching all live together, and nothing gets forgotten between lessons.

I did not build it alone. Coaches told me what they need to see to teach well, and parents told me what they need to see to know it is working. Built by a student, for students, coaches and parents.
