About this site

Best Chess Move Calculator is a free in-browser chess calculator and a small library of guides, made by the team behind ChessHelper (chesshelper.ai).

Who runs the site

The site is built and maintained by the ChessHelper team. ChessHelper is a Chrome extension and website that shows suggested moves, an evaluation bar and alternative lines on Chess.com and Lichess, with an engine strength you can set from 800 to 3200 Elo. We do not publish individual author names; every page is written and reviewed by the team as a whole.

Why it exists

People search for "the best chess move calculator" with two different needs. Some want one position solved right now, without installing anything. Others want to understand their games and get better. The free calculator on the home page serves the first need. The guides and the comparison serve the second, and that is also where our own product fits.

The ChessHelper relationship

ChessHelper is our product and we earn money from its paid plan. We rank it first for learning at your own level, and we want you to be able to judge that ranking for yourself. So we:

• say so at the top and bottom of every page;
• compare only features and prices that each company publishes, which you can check;
• name the categories where another tool is the better choice, such as Lichess for free analysis and Chess.com for players whose games are already there;
• keep the free calculator free, with no account, no ads and no upsell inside the tool.

The details are on our how we compare page.

Editorial approach

We write in plain English for club and casual players. Every move, line, FEN and evaluation on the site is checked with Stockfish and a rules library before it is published. We do not invent testers, quotes, ratings or statistics. When we could not verify a detail, we leave it out.

Fair play

The calculator and every tool we mention are for studying positions, reviewing finished games and practice against bots or in analysis mode. Chess.com, Lichess, FIDE and US Chess forbid engine help during games, and so do we.
