About Deepline

Hi, I’m Matt. I built Deepline, and my dad Xiao and I run it through Deepline Intelligence LLC, a registered company in the United States.

Matthew Ma

Founder & CEO

I’m 16, a high school student in California, and a tournament chess player: my US Chess regular rating is 1973 as of November 2026, top 4% of US Chess members, with over 400 rated tournament games since 2020.

I designed Deepline and wrote all of its code: the web app, the game analysis, the explanation system built on Stockfish, and the game importers. I also answer every support email myself.

I started Deepline in 2026 because the chess apps I used marked my mistakes but never explained them, so I built one that does.

What Deepline does

You connect a Chess.com or Lichess account and it imports your games.
It analyzes the games with Stockfish 17 and finds the mistakes you repeat.
It explains those mistakes in a chat: what went wrong, what it allowed, and what the better move was.
It builds puzzles from positions in your own games.
Every chess statement it makes is checked against the engine before it is shown.
Free to start. The paid plan is $8 a month or $70 a year.
