A writing coach in an app. It asks one question at a time, turns your answers into premise, characters, and chapters — and never asks you to know what a "logline" is. Your first book, actually started.
Tell the coach what's in your head, in your own words. It does the craft — then shows you what it heard before a single word is saved.
A solitary lighthouse keeper's ordered world breaks open when a shipwrecked child arrives carrying a map to an impossible island — and keeping the child safe means following it.
That's the whole interface: your words in, your story back — confirmed by you, every time.
Premise, characters, world, structure — built from a guided conversation, kept current as you write. The coach remembers everything, so every suggestion sounds like your book.
Ideas don't wait for your desk. Speak or type a stray thought on your phone and the AI files it in the right place — a character detail to the character, a plot turn to the outline.
coax reads your chapters aloud in a voice worth listening to. Catch a line as it floats past, and revise it by speaking.
So they're different apps. The Mac is where the book gets written. The phone is where the idea gets caught before you lose it.
One room, no modes: your documents down one side, your prose in the middle, the coach in a column beside it. You can see the whole book and the conversation about it at once.
The idea arrives on a walk, not at a desk. Speak it, and coax files it where it belongs — not into a notes app you'll never open again.
Same project, same files, already there. Nothing to export, nothing to sync by hand — it's one folder you own, on both.
Every chapter, character, and note is a plain markdown file in a folder you choose — synced by your iCloud, readable in any editor, forever. There's no export button because there's nothing to export from. If you delete coax tomorrow, you keep the book.
coax is in private beta on the Mac, with the iPhone companion alongside it. Free while it's in beta — the coach comes with starter credits, and your files are yours from day one.
Sign in, answer a few questions about the story you want to write, and we'll be in touch. We're letting people in a handful at a time so we can actually listen to them.
