ChessSolve vs Aimchess: Which Chess Tool Do You Actually Need? (2026)

If you're looking for an Aimchess alternative — or just trying to decide between Aimchess and ChessSolve — the most useful thing to know up front is this: they're not really the same kind of tool. Comparing them head-to-head only makes sense once you understand what each one is actually for.

This is an honest breakdown from the team that builds ChessSolve. We'll tell you exactly when Aimchess is the better choice, because pretending otherwise wouldn't help you.

The Short Version#

What Aimchess Is Good At#

Aimchess connects to your Chess.com or Lichess account, pulls in batches of your games, and compiles statistics about where you lose rating: tactics you keep missing, opening lines that underperform, endgame conversion, time trouble, and so on. It turns that into a weakness report and a set of training drills.

If what you want is a long-term dashboard — "what are my recurring mistakes across the last 200 games, and what should I drill?" — Aimchess does that well. It's now part of Chess.com, and it remains one of the more data-driven coaching tools available. For players roughly 1000–1800 who want a structured, stats-based improvement plan, it's a reasonable pick.

We'll say it plainly: if you specifically want automated post-game weakness reports and a drilling plan, Aimchess (or Chess.com/Lichess Insights) is built for that, and ChessSolve is not trying to replace it.

What ChessSolve Is Good At#

ChessSolve solves a different problem. It's a browser extension that overlays live Stockfish analysis directly on your Chess.com or Lichess board — best-move arrows and an evaluation readout that update as the position changes, in real time, while you're still in the position.

The insight behind it: post-game analytics tell you what went wrong after the pressure is gone. But the gap between "I understand this mistake in review" and "I keep making it in real games" is a transfer problem — the lesson doesn't stick because you learned it in a different mental context than the game. Seeing the engine's suggestion in the moment you're deciding closes that gap. (More on the reasoning in Real-Time Chess Analysis.)

So ChessSolve is for:

• Practice games and bot games where you want live feedback as you play
• Studying positions and lines with instant best-move arrows, no separate analysis tab
• Learning to generate candidate moves by seeing the top engine lines in context

Because the engine runs server-side, you get consistent depth and multiple candidate variants without your laptop or phone choking on it. It installs from the Chrome Web Store and runs on both Chess.com and Lichess.

So Which One Should You Use?#

Use Aimchess if: you want a stats dashboard that reviews many games at once and hands you a list of weaknesses and drills to work on over weeks.

Use ChessSolve if: you want Stockfish's best-move arrows live on your board — to learn patterns in the moment, study positions instantly, or train in practice games with real-time feedback.

Use both if: you're serious about improving. They're complementary, not competing. Aimchess tells you what to work on across your history; ChessSolve helps you internalize the patterns while you play and study. A complete loop looks like: train with real-time feedback → review with post-game analytics → drill the weaknesses → repeat.

On Price and Access#

Aimchess runs on a freemium model with a limited free tier and a paid subscription for full reports. ChessSolve is a free browser extension for real-time analysis, with optional higher-tier limits. Since they do different jobs, the cost comparison isn't apples-to-apples — but if your specific need is live engine arrows on the board, ChessSolve covers that for free.

A Note on Fair Play#

Real-time engine overlays like ChessSolve are training tools — for practice games, bot games, and studying. Using engine assistance in rated competitive games violates the terms of service on both Chess.com and Lichess, and both have fair-play detection. Aimchess analyzes already-finished games, so it doesn't raise this issue. Use real-time tools to learn, never to cheat in rated play.

Frequently Asked Questions#

Is ChessSolve a direct Aimchess alternative? Not exactly — Aimchess is a post-game analytics dashboard, while ChessSolve is a live, on-board Stockfish overlay. If you specifically wanted Aimchess for live engine help during practice and study, ChessSolve is the better fit. If you wanted automated weakness reports across many games, Aimchess is built for that.

Is there a free alternative to Aimchess? For real-time engine analysis, ChessSolve is free. For post-game weakness stats, Lichess Insights and Chess.com's analysis offer free options.

Does ChessSolve work on both Chess.com and Lichess? Yes. It runs on both sites as a browser extension.

Can I use ChessSolve and Aimchess together? Yes, and it's a strong combination — Aimchess identifies what to work on, ChessSolve helps you internalize patterns in real time while you play and study.

If your goal is Stockfish best-move arrows live on your Chess.com or Lichess board — for practice games, studying positions, or training in the moment — ChessSolve is built for exactly that, free, with no setup. If you want a post-game weakness dashboard instead, Aimchess is the better fit, and there's no shame in using both.
