Review flow

Start with one game

These pages all lead back to the same place: import a game, review it, and use what the review found.

Step 1

Bring in a game

Use a Chess.com or Lichess username, paste PGN, upload a file, or import a supported game link.

Step 2

Review the swing

The review workspace opens the board with move labels, eval changes, and the engine line behind them.

Step 3

Keep useful positions

Missed chances and blunders can become saved positions when the candidate is stable enough.

Step 4

Keep the history

Archive and Statistics let you reopen games and spot the problems that keep coming back.

Proof

What free means here

The engine work is local

Core analysis is not metered through a ChessIQ server. Speed depends on your browser and device.

The app keeps the thread

Review, saved positions, Archive, and Statistics use the same local game history.

Saved positions stay honest

Some games produce no valid saved positions. The app says so instead of pretending it did.

This is the real flow

The primary action opens PGN import. Username lookup opens the same review workspace after you choose a public game.

Quick answers

Is there a daily analysis limit?

Core analysis runs locally, so ChessIQ does not meter it like server-side review tools. Browser and device limits still apply.

Do I need to sign in?

No. The core review loop works without a ChessIQ account.

What happens after analysis?

If the review finds stable missed chances or blunders, ChessIQ can save positions from that game for later.

Is my PGN uploaded?

PGN review data is stored in browser storage. Public imports and anonymous analytics still use network services.
