A Lichess alternative
for the part of improvement that happens between games.
Lichess is one of the best things on the internet — free, ad-free, open source, millions of opponents. Chessful does not try to replace any of that. Chessful is the on-device companion: same Stockfish, no internet, no account, no daily quota — plus plain-language mistake explanations and adaptive training derived from your own losses. The two are complementary tools for the same player.
How does Chessful compare to Lichess?
They're solving overlapping but distinct problems. Here's where each one fits.
Where the analysis runs
Chessful: Stockfish runs on your iPhone, iPad, or Mac. No internet required, ever. Works on a flight, on the subway, anywhere.
Lichess: Stockfish runs in the cloud. Free, unlimited — but requires a connection. Mobile app caches some functionality.

How mistakes are explained
Chessful: Plain-language sentences — "you played Nxd5; the knight was your only back-rank defender." Motif detectors + on-device language model.
Lichess: Centipawn graph and engine lines. Excellent and free, but reading it well is its own skill.

Adaptive training
Chessful: Training sessions generated from the specific patterns in your mistakes (hung piece, missed fork, weak back rank…). Spaced repetition keeps the right patterns on rotation.
Lichess: Puzzle Storm, Puzzle Racer, generic puzzle pool by theme. Not derived from your games.

About Chessful
Questions
FAQ
Is there a Lichess alternative that works offline?
Chessful is the closest on-device match for Lichess's privacy and price profile, with the trade-off that Chessful has no live human matchmaking. Lichess runs Stockfish in the cloud and offers free unlimited analysis when you're online. Chessful runs Stockfish on your iPhone, iPad, or Mac with no internet required at all, no account, no daily quota, and adds plain-language mistake explanations plus adaptive training derived from your own games.
Is Chessful a replacement for Lichess?
No. Lichess is the right tool for ranked human play, live matchmaking, the Puzzle Storm, and the massive opening database. Chessful does not offer any of those — it's a focused offline training & analysis app, intended to be used alongside Lichess (or Chess.com) rather than instead of it.
Can I import my Lichess games into Chessful?
Not yet — Lichess game import is on Chessful's public roadmap, targeted for 2026 Q4. PGN import (the universal chess game-exchange format that Lichess exports natively) is targeted for 2026 Q3, which is the first path. Once shipped, you'll be able to paste a Lichess username and pull recent games into Chessful's analyser and adaptive training queue.
Why use Chessful instead of just Lichess's free analysis?
Three reasons. First: Lichess's analysis shows centipawn graphs and engine lines — Chessful translates those into plain-language sentences. Second: Chessful's training queue is generated from the specific patterns in your own mistakes, with spaced repetition, rather than from a generic puzzle pool. Third: Chessful runs fully offline on iPhone, iPad, and Mac, with no account and no daily quota.
Is Chessful free like Lichess?
Chessful has a no-ads free tier with the 40 AI opponents, Stockfish analysis on every game, plain-language mistake summaries, and three training sessions per week. Premium unlocks unlimited deep analysis, unlimited adaptive training, full skill graphs, and alternative-move exploration: €2.99/month, €19.99/year, or €39.99 once for lifetime access with a 7-day free trial. Lichess is free and donation-supported.
