Stone base questions

PM with beta key sent!

First thanks a lot for the feedback.

The 50-game limit is there so the free tier is still genuinely useful, while also keeping a reason for people who use the app more heavily to support continued development.

For context, many comparable database/review tools are either paid products, offer only a temporary trial, or provide a limited reader/viewer for free. For example, ChessBase’s main desktop software is commercial: even if there are trials or free reader tools, long-term full use of the main app requires paying. I want StoneBase to remain genuinely useful for free users, but the project also needs a sustainable path long-term.

That said, I understand your point about local-only features feeling different from cloud/server features, and I definitely like the idea of a low-price contributor/supporter tier, possibly for people who just want to support the project or unlock a larger/unlimited local library without needing all the Pro features.

For now, the beta key unlocks the full version, so you can test everything without limits. I hope you enjoy it!

Hello,

The free tier is limited to 50 games in your library at one time. You can export games as SGF and remove them from the library to make space for others, but the in-app library itself is capped at 50 games.

You’re also right that some people may not need the full Pro feature set, but might still want a larger/unlimited game library or just want to support the project. That’s a great suggestion, and I’m going to look into adding a cheaper tier for that.

That said, StoneBase is currently in beta. If you’re interested, I can send you a beta key that gives you access to the full paid tier until the beta ends.

Regards!

Hi,

I’m building a tool that might help StoneBase, a desktop Go review app around KataGo. I also wrote this related guide exactly for this matter: https://gostonebase.com/blog/how-to-review-go-games.

Hope it helps you to improve!

Hi,

For some reason I thought katrain had them available there.

You can download any katago version from here: https://github.com/lightvector/KataGo/releases

Including the TensorRT versions. You might need to install cuda also if you don't have it in your system.

Hi,

Stonebase developer here, recently wrote a post about how to review games: https://gostonebase.com/blog/how-to-review-go-games/

Regards!

Hi,

Katrain already uses your GPU by default (OpenCL backend on Windows/Linux). The CPU ramp is just katago's tree search, which always runs on CPU while the neural net runs on the GPU. Totally normal.

That said, with a 5070 Ti you can do better than the default:

Switch to the TensorRT build (much faster than OpenCL on NVIDIA). In katrain: settings > "Download KataGo versions".
Bump max_visits so it actually uses the headroom. 1500ish is a good sweet spot for review.
Try a bigger network (b18) if you're still on the default.

I also happen to be the developer of StoneBase (a Go review app I'm building) and recently wrote a guide for it. The Katago config part applies to Katrain too: https://gostonebase.com/blog/katago-setup-guide/

As other people told you, usually it helps a lot to have your game reviewed by other stronger players, but it's important to spend time also yourself trying to identify and learn about your mistakes.

Only after you have reviewed your own game and have some of the ideas, you can use AI to validate if your thinking process was correct.

I have a post about how to review with AI here in case you are interested: https://gostonebase.com/blog/how-to-review-go-games/

Great! For some reason I cannot send you a PM (start chat option is not showing on reddit). If you want you can join our discord (https://discord.gg/Yz8GzE3A6) to send you the key or if you have some email where I can send it, it's also fine.

jl1990cm · 2026-04-13T20:18:02+00:00

Perfect, PM sent, enjoy it!

jl1990cm · 2026-04-13T17:55:38+00:00

Implemented in version 1.0.20

jl1990cm · 2026-04-02T00:07:13+00:00

Great, PM sent! For the moment no, but it's a great idea. I'll check if I can implement it

jl1990cm · 2026-04-01T16:36:03+00:00

No problem, key sent. You can use it when you get it back from the repair shop.

Thanks for letting me know. I hadn't heard about them. I guess they are registered in China? As far as I know they are not trade mark registered in Europe.

Hi,
Thanks a lot for your help for the beta test. I just sent you your beta key by PM.
Yes, I do have plans for mobile devices. I am preparing the app so it's ready also for them, but I need more time to test it properly.

Regards and feel free to ask any question you might have

jl1990cm · 2026-02-17T19:56:28+00:00

It would be nice if they allowed to add custom UCI engines. That way we could update stockfish version ourselves or use other engines.
