• Simple analysis GUI for KataGo. See Releases for the latest version.
• Stone and board graphics modified from Sabaki, with thanks.
• Concept borrowed from Lizzie, with influence from KaTrain, CGoban, and LizGoban.
• Original, independent codebase.

Upsides

• Relatively simple once set up.
• I personally like the aesthetics...
• Has most normal Lizzie-ish features.
• Fully-functional SGF editor.
• Correctly handles many SGF files that trouble other GUIs, especially handicaps and mid-game board edits.
• Can load NGF, GIB, and UGI files (albeit imperfectly).
• No dependencies except Electron, quite easy to run from source, doesn't pull in a zillion npm modules.

Downsides

• KataGo not included, setup takes at least a minute's effort.
• Electron-based app, everyone hates these (they're big).

Setup

• Download and unpack Ogatak, KataGo, and a KataGo weights file.
• In Ogatak, select the menu item Setup --> Locate KataGo... (and locate katago.exe)
• In Ogatak, select the menu item Setup --> Choose network... (and locate the weights file)

Performance tips

• The setting to request per-move ownership info from KataGo (see Analysis menu) is rather demanding and you should turn it off if you experience any lag.
• Alternatively, consider changing the engine report rate (see Setup menu) from the default 0.1 (which is the most intense) to something else.
• Due to a complex interaction between KataGo's algorithm and KataGo's cache, the wide root noise setting can cause a reduction in perceived performance if you use the GUI in a certain way, especially if you commonly click through the top move. It may also affect whole-file analysis speeds.

About the analysis config file

• KataGo requires an analysis config file. Such a file is provided with KataGo as analysis_example.cfg, and Ogatak will use this if it's present, unless you explicitly specify a different file. You might find that changing some settings therein leads to better (or worse) performance. Some have found these settings chosen by the KaTrain author to be a bit faster.

Translations

• At the moment, it is possible to translate most of the menu items and some of the GUI text. See src/modules/translations.js for instructions.
• Thanks to the following translators: ParmuzinAlexander, CGLemon, Bandysol.

Talk to me

• I can often be found on the Computer Go Discord.
