AI that's read your whole book.
Not a chatbot. A co-author that knows your story.
Full manuscript context
Most AI writing tools work on the current scene. They don't know what happened three chapters ago. They don't remember your character's eye color or your world's rules.
Typewriter's AI reads your full manuscript and your entire story bible before every suggestion. It has the same context a human co-author would have.
Your voice, not generic AI
Set your style rules. "Never use adverbs." "Elara speaks in fragments." "This world has no electricity." "Third person limited, past tense." "Literary fiction. No genre cliches."
The AI follows your rules for every generation. It learns your voice from your existing prose. What comes out sounds like you wrote it, not like a machine did.
Three modes
Write: Generate the next paragraph, continue a scene, draft dialogue. The AI picks up where your cursor is and keeps going in your voice.
Edit: Improve existing prose. Tighten a paragraph. Rewrite for clarity. Adjust tone. The AI sees the surrounding context and maintains consistency.
Pilot: Open chat with your full manuscript as context. Ask questions about your own story. "When did Marcus first appear?" "Is there a plot hole with the letter?" "What's Elara's arc across act two?"

Typewriter uses OpenRouter to give you access to GPT-4o, Claude, Gemini Pro, and open-source models. Every model is part of Pro — your subscription funds them, so we can keep improving the agents instead of shipping a watered-down free AI.
