A few things worth knowing
Can I use the analyzer without paying?
Yes. Browser-based game reviews, accuracy, move grades and best-move suggestions are available free. You do not need a credit card or an account to analyze.
Can I subscribe to Pro today?
Sandbox checkout is available for testing only and cannot charge real money. Production subscriptions will open only after the paid features are ready.
What is the difference between monthly and yearly?
The proposed features are identical. Monthly would cost $5 per month. Yearly would cost $36 in a single annual payment, equivalent to $3 per month, saving $24 compared with twelve monthly payments. Final checkout terms will be shown before purchase.
Do I need to stop playing on Chess.com or Lichess?
No. Keep playing on your favorite platform, then import your completed games here to review them. ChessAnalyzer is an independent tool, not affiliated with Chess.com or Lichess.
Does Pro include AI chat or faster cloud analysis?
Not in this proposed plan. We are focusing on saved reviews and personal mistake training. Stockfish analysis currently runs in your browser on both plans.
Is there a lifetime plan?
No lifetime plan is planned. A recurring membership would support ongoing storage, maintenance and improvements without a complicated set of tiers.
