Answers.Text: Why do you say the engine analysis at lichess is weak? Stockfish is afaik one of the strongest engines out there, if not the strongest. Unless the depth is somehow limited very much, I can't imagine the engine strength to be below GM level.

Answers.Text: @TMM The depth is per default 21. That's good enough for simple tactics, but nothing more. If you want to get good moves in complex positions, you need at least depth 40.

  **Lichess.org** has a feature called [studies](https://lichess.org/blog/V0KrLSkAAMo3hsi4/study-chess-the-lichess-way). You can add your game as a *chapter* in a study, invite your friends as contributors and make that study public or private. You have a (rather weak) engine analysis, a small database of chess games, and a chat. You can annotate your game, add alternative lines and so on.
  The multi-chapter option makes that very useful for much more than game analysis. I'm using it primarily for opening studies.
  
  Here is a screenshot from my [Caro-Kann study](https://lichess.org/study/4Aqycynk):
