Ghostwriter

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.

Fostera's AI Ghostwriter studies your actual writing. Emails, messages, posts. From that it builds a model of your voice, so a drafted reply 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 context, so email doesn't read like Slack
  • Always presents drafts as suggestions so you stay in control
