Which Go boards can it read?
9×9, 13×13 and 19×19 boards, and it works out the size by itself. A normal phone photo works, from above or at an angle, as long as the whole board is in the picture.
How are the points counted?
With KataGo, the open-source Go engine. Pick area (Chinese) or territory (Japanese) rules and the komi; for territory rules, add the stones each side captured during the game. KataGo decides which stones are dead, and you can tap a group to overrule it. If the game isn't finished, it shows KataGo's estimate instead.
Why do I have to turn the board and pick who plays next?
A photo can't show which corner is A1 or whose turn it is. Turn or mirror the board until it looks the way you play it, and choose Black or White to play; the SGF follows.
What can I do with the position?
Copy it as SGF or download a .sgf file, and open it in any Go program or server that reads SGF, such as Sabaki or OGS. Each scan also has its own link.
What if a stone is read wrong?
Tap the point to change it: empty, black, white. Points the reader wasn't sure of are ringed. This is a beta, and the fixes you make are what teach it real boards.
Is it free? Do I need an account?
It's free and needs no account. Photos you send are kept to improve the reader; the privacy policy says what is stored.
