1. Enjoy Go easily with the strongest artificial intelligence Katago on your mobile.

- It is the most upgraded artificial intelligence Go that surpasses the professional Go player.
- Anytime, anywhere, you can easily improve your energy by mobile.
- KataGo levels are divided into 3 levels, so you can choose your desired game power. (Pro 9+, Pro 5+, Amateur Dan)
- There is no game time limit and the game is automatically saved.
- You can continue playing at any time.

2. 3 number of AI recommendations and variation of change

- Ask KataGo to find the next best move, 3 referrals.
- You can see the variation of change that KataGo thinks for each move of recommendations.
- Improve your energy through the AI recommendations and variation of change.

3. AI situation judgment

- Artificial intelligence does not count points differently from people, but determines how strong it is based on the size of ownership.
- The size of ownership is represented by the size of a square, so this size tells you how the AI can figure out what's going on.

4. First try of the Go game with the 'Opening Game'.

- It is a reality that even professional Go players are difficult to play a game with a KataGo equally. But, what if it's only for 'opening game’?
- You can set the first 5 moves within 50 to play with the desired stone.
- Take a look at how artificial intelligence responds with various opening games. Sooner or later, you will feel that you are a leader in opening games.

5. ‘AI recommendations’ and ‘AI situation judgment’ are possible even in the case of reviewing current game and reviewing previous games.

- In addition to simply reviewing the current game , it is possible to grasp the situation according to various changes in development by using 'AI Recommendations' and 'AI situation judgment' in black or white turn.
- It is important to have a good teacher in Go, but it is also very important to review the previous games. You can study well because you can use ‘AI recommendations’ and ‘AI situation judgment’ for reviewing the previous games.

6. Reasonable system

- The strongest artificial intelligence Go that surpasses professional Go players
- Easy on mobile
- Without worrying about heat or battery (AI engine does not work on mobile, it works on powerful server)
- Without time limit and people stress
- You can study while enjoying Go.
- Avoid indiscriminate advertising.
(There are no interstitial AD insertions that stress the users.)
- We are constantly upgrading and will continue to progress. (A lot of comments would be appreciated.)

The ‘AI KataGo Go(Baduk)’ app was developed with the motivation to become a means to help users in their hobbies of Go, rather than a simple Go game.
Considering the server maintenance cost, the service is provided at a reasonable price, and I think it has a significant service price advantage compared to other services.
Please use it a lot.

Thank you.
