VoiceMoat is a writing tool for creators on X who want to use AI without sounding like everyone else's AI. At its core is Auden, the brain inside VoiceMoat: a creative writing partner trained on your full profile (100 to 200 of your posts, replies, threads, and images) across 10 signals of voice, not a general model prompted with a few examples. Every draft comes back with a voice match score against your baseline, and anything that drifts off-voice gets caught before it ships. Train Auden once, then write in your voice every day. Your voice is your moat.
