Ghostwriter: write a piece one good sentence at a time

Today we're launching Ghostwriter, a writing tool that builds your draft one sentence at a time. For each line it drafts ten options, one from each of the leading AI models, and ranks them so the most natural-sounding choice sits at the top.

Pick, tweak, or write your own

Each sentence is its own small decision. Pick the option you like, tweak it until it reads right, or ignore them all and write your own. The least machine-sounding line is ranked first, so the top suggestion is usually the one you keep.

Or let it write the whole thing

Don't want to choose line by line? Auto-write drafts the whole piece while you watch, working sentence by sentence and keeping the strongest option each time. You end up with a finished draft you can still edit freely.

It learns how you sound

As you go, Ghostwriter learns your voice from the choices you make, so its suggestions start to sound more like you. The more you write with it, the less editing you do.

Hands-off through your AI assistant

Ghostwriter also runs hands-off through AI assistants and agents over MCP. Ask your assistant to draft a customer update, a LinkedIn post, or a tricky email, and Ghostwriter writes it in the background, one ranked sentence at a time, then hands you a draft to approve.

Ghostwriter is included with every plan, and higher plans give you more AI usage. Start your free trial and write your first piece in a couple of minutes.
