Problem
Busy professionals often struggle to consistently share their insights on LinkedIn because creating authentic, audience‑targeted posts and accompanying visuals is time‑consuming and requires writing skill, research, and design effort.
Solution
Coauthor is an AI‑powered writing partner that learns a user’s personal “Professional Signature” from onboarding inputs, existing writing samples, and ongoing edits. It generates daily LinkedIn post ideas, drafts complete posts in the user’s voice, and suggests eye‑catching images based on key quotes. The platform automatically fact‑checks claims, tailors messaging to the user’s target audience, and continuously refines its output as the user edits or approves content. Users retain full control, reviewing and approving each post before publishing, while the system handles research, drafting, and visual creation, reducing the weekly time spent on content creation.
Target Audience
Coauthor is aimed at founders, executives, sales leaders, consultants, coaches, and other professionals who need to build influence on LinkedIn but lack time to write and design posts regularly.
