PostOwl
AI social scheduler that learns a founder's writing voice to draft posts and replies across X, LinkedIn, Instagram and more.
What it does
PostOwl trains a private AI voice model from a user's past posts and replies, then drafts new posts, comment replies, and keeps a content queue full across social platforms. It also works as a plain scheduler and ships an MCP server so agents like Claude can post directly.
