Everything a novel needs to stay one book
Tools made for a novel rather than for a document: a world that remembers, an AI assistant that writes with you, and a record of every change you can walk back.
Story organization
Keep your narrative structured and accessible
Chapters and arcs
Chapters and parts, rearranged as the story demands, with every version kept.
Worldbuilding
Places, cultures and lore, kept where the assistant can find them and you can check them.
Character development
Characters that stay themselves
Character profiles
Every character is drawn from your manuscript as you write, with the paragraph each fact came from. Edit the sheet, and the assistant writes from it.
Talk to them
Sit a character down and talk to them, in their own voice.
The findings
When chapter nine forgets chapter two
Findings, not red ink
A contradiction becomes one card: the quote, the reason, a fix to approve. Approve it and the chapter changes with the old version kept; ignore it and the world learns that this is how the story goes.
Writing with the assistant
A writing partner that has read everything you wrote
Writing suggestions
Ask for the next paragraph, a revision, or an answer about the book. The assistant writes from your world, in the guidelines you set.
Story weaving
Your characters, locations, lore and plot arcs are brought together into story-aware continuations.
Writing guidelines
Define rules and constraints that keep tone, style and narrative choices consistent.
Your own model
Write where you already think
Claude and ChatGPT
Connect Quillsmith to the Claude or ChatGPT you already pay for. Your model gets what the chapter needs and nothing else; the chapter comes back into the world, checked like any other. Available on every plan.
Privacy and security
Your work stays yours
Secure by default
Your content is transmitted securely and stored with industry-standard protections.
Never used for training
We never use your writing to train a model. Ever.
Take it with you
Export your manuscript whenever you like. What you write stays yours; we claim nothing of what Quillsmith writes for you.
