Product design

A review that begins with the player’s idea.

Go AI Coach is being designed to turn a completed game into a reasoned learning sequence. This page describes the intended product direction; the public review service is not yet available.

1. Start after the game

The intended workflow begins only once a game has ended. Go AI Coach is not designed to suggest moves during an active game, and it should not be used to bypass the rules of a server, club, event or tournament.

2. Reconstruct the intention

A numerical swing can show that a move mattered. It does not necessarily show why the move felt reasonable. Reasoning Replay is intended to help the player name what they noticed, feared or tried to accomplish at that moment.

That intention becomes a hypothesis to examine—not a fact inferred with certainty and not a judgement about the player.

3. Compare the idea with the position

The product design separates two layers:

LayerRole
Validated position evidenceBoard state, legal moves, candidate comparisons and other deterministic facts remain authoritative.
Coaching languageGenerated language may organise and explain validated evidence, but should not invent board facts or overstate close decisions.

4. Ask “Why not my move?”

A natural-looking move can answer the wrong question. The intended comparison explores what the player’s move achieved, what it left unanswered and why another priority mattered more.

Where alternatives are close, the explanation should say so. A small difference should not become a dramatic mistake simply because dramatic wording sounds more decisive.

5. Build a reusable lesson

The review should end with something the player can recognise again: a whole-board priority, shape issue, reading habit, direction-of-play choice or another recurring decision pattern.

Patterns and drills are intended to turn that lesson into deliberate practice rather than leaving it inside a single game report.

Important: Product behaviour, supported game formats, account features, model providers and service availability are still under development. They will be documented only when verified.
