99chess
A free chess coach that explains the plan, not just the move
99chess is a free chess trainer with an AI coach. It explains what your move did and what the plan is — in plain words, like a human coach. Adaptive engine opponent, game review, puzzles built from YOUR mistakes with spaced repetition. No install, no card.
Hey Product Hunt! Solo dev here 👋
The story behind this one is a bit silly. I'm a badminton player — and
some months ago I got sick and was stuck at home with zero badminton.
Out of boredom I opened a chess board. I'd only played a couple of
games as a kid, badly. It hooked me within a week.
I did what every adult beginner does: bought premium on the big chess
sites, ran the lessons, reviewed every lost game. And hit a wall.
Their review tells you "this was a mistake, the right move was Nf5" —
but never WHY. What's the idea behind Nf5? What's the plan? Which of
my pieces is bad and what am I even fighting for? An answer key is not
a coach.
So — chess YouTube. Great content, hundreds of hours of it. A month
later I realized it was eating every evening and my rating had barely
moved. Watching chess is not training chess.
That's when the developer in me woke up. I wanted a trainer that takes
you by the hand: explains every position in plain words, builds
training out of YOUR OWN mistakes, and grows your understanding — not
just your puzzle streak. I couldn't find one, so I've spent the last
months building it. That's 99chess.
What it can do today:
🧠 **An AI coach that talks like a human.** After your move it explains
what it did, what the opponent's reply changed, and what the plan is
now. Threats first, development second — like a real coach at the board.
♟️ **An engine that adapts to you.** It studies your games, plays at
your strength (beginner to club level) and picks varied openings — a
sparring partner, not an execution squad.
🧩 **Puzzles made from YOUR mistakes.** Positions where you actually
went wrong become your puzzles, and spaced repetition brings each one
back right before you'd forget it.
📈 **A personal training program.** Import your chess.com or lichess
games by username — the coach finds the mistake that costs you the most
rating points and builds a weekly theme around it.
Everything above is free: no card, no trial timers, runs in the browser
(mobile too). A free account is only needed so your progress has
somewhere to live.
I'd love brutal feedback — especially from adult improvers who started
late like me, or from anyone stuck at the same rating for months. What
would make you actually train instead of blitzing another ten games?
