Description from store
This extension adds a lot of extra functionality to the https://lichess.org web site.
Main features:
- Extended Interactive Lessons allow you to play ALL variations
- Explorer Practice allows you to play against the moves in Opening Explorer, essentially helping you train against any rating bracket on the Internet or a specific opponent
- local computer analysis chart when no server one exists, even when not logged in
- Enhanced PGN Import in Analysis board allows you to merge multiple PGNs into a single one (lichess limitations strip down the comments, but I am working on a solution). This helps you quickly collect a player's repertoire and maybe save it as a study Interactive Lesson, simulating their play. Then you can export the current analysis moves into separate lines as well, or just copy a single branch as a PGN.
- See evaluation of possible moves of the selected piece in analysis
- Automatic detection of interesting/brilliant/good/best moves
- a PGN editor supporting a lot of operations and accepting tens of megabytes of text

- Change the friends box into a menu or a button, live update Friends page,
- Sound and voice notifications where players you follow start playing (with mutable option per player)
- TV enhancements: Current games section for players you follow and streamers, menu to go to previously opened games, previous two games in player TV just like in category TV

- (2025-06-17) Fay Sha: idk
- (2025-06-14) Deepak Shah: very nice!
- (2025-05-21) Fide Chess: very nice definetly recomend this
- (2025-05-01) AB ARUN: good
- (2025-04-11) Mithilesh Upadhyay: I really love this extension—it totally motivates me to play more chess! It feels like the opposite of addiction! If you could add themes for Lichess, that would be awesome. Seriously, you’ve done a fantastic job with this app, making it way more engaging. Not sure if you’ve checked out the Lichess beta on the Play Store, but their setup is amazing. It’s pretty much the same as Lichess, nothing new, but it’s _fantastic_ and a little _quaintish_ (not sure if I just made up that word! ≧▽≦). I really hope you think about adding this feature. It wouldn’t be too much hassle, but I just love your extension!
- (2025-03-06) Gokula Anand: Awesome for studies particularly pgn splits and merges etc. Instantaneous response from developer - always. He does not say "read user manual thoroughly" (which i didn't do whenever i asked him doubt), he explains and gives link clarifying the doubt. Great !! to have with fabulous lichess
- (2025-03-01) MarEZ: I really like this extension! Could you add a setting to flip the board, similar to chess.com?
- (2025-02-22) Дмитрий Б.: It's just an amazing extension! Until I started using it, I didn't even imagine that it was possible to boost the analytical capabilities of Lichess like this. This extension allows you to add to Lichess the best that is available in commercial chess.com and ChessBase! What is especially pleasing is that the extension is constantly evolving and its author listens to the wishes and needs of users. Thanks a lot to him!
- (2025-02-03) Alekhine Defense: absolutely awesome extension. I was wondering whether it was possible to add a feature displaying the average score of the higher rated player in the opening explorer. At least in the master database that would prove to be very useful for choosing opening lines.
- (2025-01-19) Pradeep Agrawal: What the F##k,U just made lichess so good that i can't even differentiate if this is actual lichess.The board , options all are 1class.Btw can u add another feature like multiple premoves like chess.com that would be great!!Btw good extension,may u add this feature.
- (2024-12-29) Reza Ggg: Can i disable zoom in all entries lichess site in mobile?
- (2024-12-11) toscar22 Link: Extremely useful, messaged a Mod/creator this morning, instant response, just an all round must have tool, 5stars through& through
- (2024-12-03) Anshuman: this is the best lichess extension ever!!!!!!! huge thanks to siderite!
- (2024-11-06) Abhinav jha: This is a great extension... brillant move looks like inaccuracy due to this !? symbol please change it to !! ...,,, love you tool btw..
- (2024-10-22) Hamzah Malik: sooo good
- (2024-09-25) Asuyut Borah: Thank God who ever made this draw line Chrome extension for Android but I found a bug when I use bt mouse it didn't work on mouse I mean when I tap on arrow button it didn't work
- (2024-09-16) Adrian Oratowski: I can't express enough how this extension completely transformed the way I use studies on Lichess. I spend a lot of time working on studies and often I had to find ugly workarounds for Lichess limitations. I randomly run into the extension and almost cried when I installed it. It has all the features I needed, like playing through all variations in interactive lessons, playing through transpositions or PGN editor but on top of that it also has somewhere around ten dozen other features that I didn't even know I needed but now I can't live without. It's like Lichess on steroids but also rocket fuel, triple shot of espresso and a side of energy drinks to boot.
- (2024-09-10) R i (ker): The extended interactive lessons feature is very useful! I would recommend this whole heartedly though truthfully, I think it would be better if the main features were just integrated into lichess.
- (2024-09-09) Steffen Wirth: This is a must!
- (2024-09-08) james pond: Super useful extension! It's amazing how many tools are in it. Your interactive studies can now have variations in them which is not possible without the extension, but there is also so much more. It was the lack of using variations to interactively practice openings that caused me to purchase Chess Position Trainer, but now I only use it when my Internet goes out. Also, the creator is always very brisk at repairing any bugs.
- (2024-09-07) Rob Sharp: A great extension that adds a lot of functionality to Lichess. I personally love the new way of tracking when your friends are online and playing games.
- (2024-09-06) D B: Well documented, fills a functional niche of things I have been looking for. But now testing it. I am looking for chess variations tress navigation control from user-end and that seems to be the driving force behind the proposed features. It is rich in many features. Perhaps Lichess could find inspiration in there. Plus there is a github repository, with issues where one could report problems, while having normally enjoyed the extension. Help the dev. help us.

- (2024-09-05) Davies Njuguna: not working
- (2024-08-05) Francesco Vocali: The perfect trainer for opening and other studies, plus many other nice features. 5 stars.
- (2024-06-01) Justin Yeung: Many useful features
- (2024-05-30) Mark: LiChess Tools is an absolute game changer and has helped me immensely with studying openings. You would think an extension with so many enhancements could cause lag and other issues but it actually provided a smoother, aesthetic Lichess experience with the nicer piece drag, slimmer arrow option, and the "fix eval freeze" option! There are no downsides at all. I do not ever see myself using Lichess without LiChess Tools 💯💯💯
- (2024-05-15) Bennie du Plessis: This extension changes a good site, to a very good site. Lichess is not complete without Lichess tools
- (2024-05-12) Ken Kaneki: This extension is awesome! It allows me to draw arrows and circles on Lichess.com on mobile. I'm really happy I found this! Additionally, the developer is very cool and helpful. This extension also enables the evaluation bar for Lichess mobile, which is fantastic."Ty dev💐
- (2024-04-09) CropCircles: Amazing! I was really wanting a way to play all variations as it's so valuable for opening drills. Great work!
- (2024-03-24) Aariz: its cool.
- (2024-03-02) SeAoFbLoOd (Никита Кальников): kaif'
- (2024-02-28) StJukes: I keep discovering new things with this. It is perfect. The only issue I have had is some things weren't explained properly in description. E.g. what does the blue and green line mean in the eval bar in analysis? Description only said "extra computer analysis metrics on charts and eval gauge". Despite this I can't rate lower than 5/5.
- (2024-01-31) Dan Mintz: Listen Guys! If you are a serious lichess user, THIS IS the extension to have! Super charge your study experience and much more. And it is free!!!!
- (2024-01-27) Kyle Bond: Great plugin.
- (2024-01-20) Саша_Косцов: LiChess tools is realy good!
- (2024-01-11) Davies Njuguna: Extended Interactive Lessons allow you to play ALL variations i dont see an option to play all variations i only play mainline, i'm using opera GX
- (2024-01-03) kiarash karimi: nice tool :)
- (2023-12-13) Xaver Hellauer: Some great features, in particular, I installed it for the highlighting of transpositions. Unfortunately, this extension will make use of your account to promote its Lichess team by joining you without asking. This is a major red flag that raises concerns regarding the extensions activities beyond your control. Therefore, I cannot recommend this with a good conscience.
- (2023-12-10) Olekaze: nice tool :)
- (2023-11-30) abu bua: That is such a great tool! Thanks! Where can I made a donation?
- (2023-11-26) Mick: Amazing stuff
- (2023-11-20) Karthick: amazing
- (2023-11-17) Tryfon Gavriel (kingscrusher): Absolutely brilliant extension. I have being doing a lot of Gambit analysis recently and the developer was able to help me organise and visualise analysis so much more effectively with the options added. There is a wide range of options which really supercharge the Lichess site in various ways. Well worth getting. Cheers, K
- (2023-11-05) Felix Led: Thank you, siderite! :D I was in contact with the developer of lichess tools, because it didnt work at my pc at first. Siderite helped me out a lot over discord and we discovered, that my OS was the problem: I have windows 7 on my pc. Lichess tools seems not to work on a windows 7 system. On another laptop with windows 10 it worked fine instantly! Thank you for your awesome lichess tool, Siderite, and for your help! :D For all other users: Lichess tools only works with windows 10 or higher! Greetings Endspiellehrer
