AI Ghostwriter That Writes in Your Voice

Feed it your emails and writing. It learns your cadence, vocabulary, and tone — then drafts messages that sound like you.

Create your GhostwriterBrowse Souls

Fostera’s AI Ghostwriter studies your actual writing — emails, messages, posts — and builds a model of your voice. When you need a reply drafted, a message composed, or content written, it produces text that reads like you wrote it. The more you feed it, the sharper it gets.

  • Learns your writing style from emails, messages, and samples
  • Drafts replies and content that match your voice precisely
  • Gets better over time as it absorbs more of your writing
  • Adapts to different contexts — email vs. Slack vs. long-form
  • Always presents drafts as suggestions so you stay in control
