Every character. Every scene. Every contradiction.

Open any character in your story bible. See every chapter they appear in. Every line they've spoken. Their arc status. Their relationships. Their last scene.

Typewriter tracks this automatically. You don't fill in cards. You don't maintain a spreadsheet. You write, and the tracking happens.

Elara has brown eyes in chapter 3 and blue eyes in chapter 27. She's afraid of heights in the prologue and climbing a bell tower in chapter 12. Marcus's letter is mentioned in chapter 4 and never explained across 34 chapters.

Your readers would catch it. Your professional editor would charge you for it. Typewriter catches it while you're still writing.

Characters don't exist in isolation. Typewriter tracks who knows who, who's spoken to whom, and how relationships change across your manuscript.

When the AI writes dialogue between two characters, it knows their history. Not just their traits. Their actual interactions in your story.

When you ask the AI to write a scene with Elara, it knows she speaks in fragments, has brown eyes, was last seen at the cliff's edge, and is afraid of heights. Not because you told it. Because it read your book.

Character tracking isn't just a reference tool. It's the context that makes the AI actually useful for fiction.
