AnkiChess is TowelSniffer's project: github.com/TowelSniffer/Anki-Chess-2.0, with its Companion add-on. This add-on replaces neither of them: it only publishes, separately, some improvements proposed to that project, so they can be used and tested before they are part of an official AnkiChess release. Once they are, this add-on is no longer needed.

The improvements are proposed in these pull requests to the AnkiChess project:

• #119: an importer for Lichess studies, analysed games and puzzles; gamebook chapters played as on Lichess; Chess.com Game Review marks on the board; copying the analysis as PGN or as a new card; rebuilding pawn structures on the board
• #118: move comments on the front of puzzles
• #120: castling written with zeros (0-0)
• #123: a board size option
• #124: Lichess-style player bars, and the settings menu moved off the board
• #125: the board fitting the screen on AnkiDroid 2.25.1+
• #126: any checkmate accepted when the puzzle's answer is checkmate
• #127: hints while solving puzzles (the piece, the move, then the move played)
• #128: the reply that punishes a wrong move, shown before the move is taken back

Importer (Tools > Import into AnkiChess…)

• Lichess studies: paste study links, list a user's studies, open .pgn files or paste PGN. Each chapter shows whether it is new, already imported or changed on Lichess; choose its side, note type and deck before importing. Opening lines, tactics, annotated games, key moves and structures go to their own subdecks. Update imported Lichess studies brings in the chapters that changed. When Lichess limits downloads, the add-on waits and tries again; with a Lichess token the limit applies to your account instead of your IP.
• Games: analysed Chess.com and Lichess games become puzzle cards for your blunders, mistakes, misses and missed mates, plus cards for the opening book line (Stockfish, downloaded when needed, or Lichess' server analysis).
• Puzzles: your Lichess puzzle activity (the failed ones by default), or puzzle links.
• If your collection has no AnkiChess note type yet, the window installs the official AnkiChess template from the AnkiChess project on GitHub.

Card improvements

This add-on carries a preview of the AnkiChess card template with the improvements above, and points your AnkiChess note types at it: only the script the cards load changes, their HTML, styling and settings stay. Some of them are options in the card's settings menu: Comments on Front, Board size (px) and Player Bars.

• AnkiChess > Manage chessRs Notes (Companion add-on) shows the preview's settings too: hints, refutation and the other new options, for each note type (synced to AnkiDroid).
• The preview applies while your official template is version 1.3.00. When the Companion installs a newer official version, that one is kept.
• To go back to the official template, set "preview_template": false in Tools > Add-ons > Config. Do it before removing this add-on; otherwise the preview stays until the Companion updates the template.

Interface in English or Brazilian Portuguese. Tested with Anki 26.09.3.
