Coauthor
RivendicaCoauthor is an AI writing partner for LinkedIn posts in your authentic voice, with drafting, daily ideas, images, and fact checking.
Overview
Coauthor is an AI writing partner for professionals who want to publish LinkedIn content in a voice that feels like their own. It learns from your background, writing samples, and interactions to build a “Professional Signature,” then uses that context to draft posts, suggest ideas, and generate supporting images.
The product is aimed at people who have expertise but limited time to turn it into consistent content. Coauthor keeps the user in control of what gets published, supports review and revision before sharing, and includes fact checking on supported plans to reduce obvious errors in posts.
