How to choose a chess AI helper

Four questions narrow seven good tools down to the one or two that fit how you actually play and study.

Published November 12, 2026 · By the Chess AI Helper editors (ChessHelper team)

Our ranking puts ChessHelper (chesshelper.ai) first because it fits the widest range of players. That does not make it the right first tool for everyone. The chess AI helpers on the market do different jobs, and picking well is mostly a matter of knowing which job you need done. This guide walks through the questions in the order that settles them fastest.

Start with where you play

A helper that lives where your games are gets used; one that needs exports and uploads gets used on weekends, if at all. So the first filter is your platform.

If you play only on Chess.com, its built-in Game Review is already there after every game. If you play only on Lichess, its analysis board is free and unlimited. If you play on both, or want the same tool on both, ChessHelper is the one helper on our list that works on the boards of both sites with a single extension. Tools such as DecodeChess, which take PGN uploads, work with games from anywhere but add a step.

Device matters too. ChessHelper needs Chrome or another Chromium browser on a computer. Noctie and Lichess have phone apps. DecodeChess has an Android app but no iPhone app listed.

Decide what you want the helper to tell you

This is the question most people skip, and it decides more than any feature list. Chess AI helpers answer four different kinds of question.

If you answer “all of them,” pick the first one you would use daily and add a second later. Two tools that do different jobs beat three that overlap.

Match the engine to your rating

A full-strength engine is always right and often unhelpful. The best move it finds may depend on a long forcing line that a 1200 player cannot see or remember, so the lesson gets lost. The worked example below shows the difference.

After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5, White attacks the f7 pawn with knight and bishop. This is the Two Knights Defense, and Black has to decide how to respond.

We checked the position with Stockfish at depth 20. Its top choice is 4...d5, which it rates as roughly equal. The natural-looking alternatives are much worse: 4...Nxe4, grabbing a pawn, comes out at about +2.0 for White, and 4...Qe7, defending f7 directly, at about +2.5.

A full-strength tool will also show the long main line after 4...d5 5.exd5, which branches into sharp sacrifices that even club players study for years. A helper set near your level keeps the focus on the idea you can use: block the bishop's attack on f7 with a pawn, and do not grab material while your king is under fire. That is why we rate level control as the most important feature for learning, and why ChessHelper's 800 to 3200 Elo range ranks it first.

Check how it explains

Arrows and evaluation numbers are fast; sentences are slower but stick. Decide which you need. If you can usually see why the engine's move works once it is pointed out, arrows and an evaluation bar are enough and save time. If you often stare at the engine's move without understanding it, look for written explanation: Chess.com's coach comments on key moments, and DecodeChess explains threats, plans and concepts for every decoded position.

Also check whether the tool asks you to try first. Chess.com's Retry button and Lichess's “Learn from your mistakes” make you find the improvement before showing it, which is how a coach would work. Use any tool that way, even if it does not force you to: pause, guess, then look.

Set a budget

Several good options cost nothing, and the paid ones are in the same range. Prices below are as listed in November 2026.

A sensible free setup is Lichess for deep analysis plus the free tier of one level-aware or explanation-focused tool. Pay when a daily limit starts to get in your way, not before.

Rule out anything framed for use during games

Some extensions advertise help during live games against people. Using any of them that way breaks the rules of Chess.com, Lichess, FIDE and US Chess, and accounts get closed for it. Choose tools that present themselves as study aids, and keep any on-board helper switched off whenever you play a person. Our guide to using AI helpers fairly sets out the actual rules.

Three quick profiles

A beginner around 800 who plays on both sites: start with ChessHelper on its free plan, set a few hundred points above your rating, and use it on bot games and finished games. Add Lichess for free deep checks.

A 1500 Chess.com player who plays one serious game a day: use the daily Game Review on that game. If you keep making the same kind of mistake, add Aimchess for a monthly report.

An adult improver around 1700 who studies slowly: DecodeChess for written explanations of your key games, plus Lichess for opening research. If you also want suggestions pitched at your level while studying on Chess.com or Lichess, ChessHelper covers that. The getting started guide shows the setup.
