ContentIn is a web-based AI ghostwriter for LinkedIn, built for founders, coaches and consultants who want to post consistently. It learns a user's writing voice from their existing LinkedIn posts, then drafts new posts, plans a week of content and schedules it for publishing. The company positions it for founders who want LinkedIn to generate leads.
Unlike a general chatbot, it keeps a knowledge base about the user's business, stories and audience, and treats edits and published posts as feedback. Ideas, drafting, scheduling and analytics sit in one place. ContentIn LLC operates the product, and its about page names Sebastian Kinzlinger as founder and Flavio Amiel as CMO.
Setup begins with a public LinkedIn profile URL. ContentIn reads the profile and past posts to learn voice and topics, so the first draft already resembles the user's writing. The company says the voice model is built from at least 20 existing posts. Users then complete a roughly 10-minute interview that loads their stories, offers and audience into a knowledge base.
Each week the user adds what happened, including wins, client stories and half-formed thoughts, and ContentIn turns it into a week of posts. The company says most users change less than 10% of a draft. Every edit and published post feeds back into the model, and the site says drafts get closer to the user's own writing over time.
The core is the AI Ghostwriter, trained on a Voice DNA profile covering sentence length, vocabulary, how a post opens, storytelling patterns and emoji use. Around it sit an idea generator, an idea manager and ideas from any pasted URL. A weekly plan drafts next week's posts every Sunday from the user's own material, asking one question per post.
Publishing tools include a scheduler for personal profiles and company pages, scheduled first comments for links or lead magnets, AI images, quote cards and carousels. Analytics show which angles worked, and repurposing reruns successful ideas. A Telegram bot supports mobile use, and a LinkedIn MCP server connects Claude, Cursor or another MCP client on the Pro plan.
