What ContentIn does
ContentIn is a LinkedIn content tool aimed at founders, coaches, consultants and other solo professionals who want to post regularly. You give it your public profile URL, and it studies your existing posts to build a personal writing model, which the vendor calls Voice DNA. An interview and uploaded documents then fill a knowledge base with your stories and offers. From that material it drafts posts, plans a week every Sunday, and publishes on schedule through LinkedIn's official API, so no LinkedIn password is requested.
Around the ghostwriter sit an idea manager, idea generation from any URL, a scheduler with follow-up comments, AI images and quote cards, AI comment generation, post analytics and a Telegram bot. A LinkedIn MCP server for Claude, Cursor or other MCP clients is included in Pro.
There is no free plan. Growth costs $39 per month billed monthly or $31 per month billed yearly, covers one personal profile and plans 2 posts a week. Pro costs $59 per month billed monthly or $48 per month billed yearly, plans 3 posts a week and adds company pages and leads analytics. A Ghostwriter / Agency tier is listed as Custom for multiple profiles and team seats. Every plan starts with a 7-day free trial that asks for a card.

Cons
- No free plan; the 7-day trial asks for a card

Our take
ContentIn suits a founder or consultant who knows what to say but lacks a posting routine, and who wants drafting, scheduling and analytics in one place for LinkedIn only. Its voice model needs at least 20 existing posts, so people with little posting history have less to train on. There is no free plan, the trial asks for a card, and Growth caps planned posts, ideas, carousels and images. Company pages require Pro. Teams managing several people must contact the vendor for custom pricing. Voice quality claims come from the vendor and were not checked by us.
