Free chess game analysis, $17K in 30 days: review every move
Chessigma is a free chess analyzer that reviews games, grades moves, and provides training tools. Its $17K in the last 30 days is verified through the payment provider's API by TrustMRR (Stripe), as of September 30, 2026.
What it actually sells
Chessigma is a free chess analyzer that runs on users’ devices. It generates detailed game analysis reports and insights from Chess.com, Lichess, or PGN games, with no signup required. Recent games can load through a Chess.com or Lichess username, while saved games can be pasted or uploaded as PGN files.
The reports show overall accuracy, identify openings, and highlight best and worst moves. Every move receives a grade from Brilliant to Blunder based on how much it changed the player’s chances, and the engine provides its top choice for every position.
How it charges
Chessigma is completely free, with no paywall, daily game limit, premium tier, or signup required. Its site also promotes free chess openings training and a free chess AI that returns the Stockfish best move from a FEN input.

Where it sits in the data
Chessigma's $17K in the last 30 days is higher than 96% of the 5,602 projects with payment-verified revenue in our dataset; the median across them is $150. Within the “Games” category (174 projects) it is higher than 95% (category median $170). Snapshot: 2026-09-02 to 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.
Currency
All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.
Could you build something like this?
My view is that demand comes from chess players who want an immediate review of recent games and a clear account of the moves they missed. The buyer is the player using the analysis, training puzzles, coaching, openings trainer, or FEN checker.
Distribution would need to meet players through the platforms where they already play and search for game review. Building it would require reliable game imports, accurate engine analysis, useful reports, mobile support, and fast performance. Competition, trust in move evaluations, and the support load created by chess-specific requests would need real work.
Verdict: Needs real work.
One thing to take from it
My view is that one product can give players several practical entry points: imported games, username lookup, PGN uploads, FEN checks, opening drills, mobile apps, and a community. Each surface leads back to the same core offer of chess analysis and training.
