Frequently Asked Questions

Coauthor is an AI writing partner that helps busy professionals quickly craft social posts in their authentic voice—so you can build influence without spending hours writing. Today, Coauthor researches personalized content ideas daily, writes LinkedIn posts, and creates attention-grabbing images.

Coauthor gets to know you and builds a personalized “Professional Signature” for you based on who you are and how you communicate.

It also uses Multi-Model AI: it combines AI models from OpenAI, Anthropic, and Google Gemini to craft posts that genuinely sounds like you, without complex prompts. Traditional AI writing tools can require extensive prompting and often produce generic content in a telltale AI style.

Coauthor also continuously learns and improves every time you interact with its ideas or refine your posts.

Coauthor is for doers: busy professionals with valuable insights but limited time to share them. This includes founders, executives, team leaders, subject matter experts, consultants, and professionals who want to build authentic influence online.

Currently, Coauthor focuses on creating content for LinkedIn. We’re considering adding support for additional platforms including Twitter/X.

Coauthor is developed by Neon Data, Inc., the company that also develops Hunch. Neon Data was founded by a small team of engineers and designers to help people be more productive with AI. Hunch is a tool that any knowledge worker can use to automate their work with AI.

Coauthor was built using Hunch. All of Coauthor’s AI-powered capabilities—onboarding, post writing, idea generation, refinements, learning, fact checking, and more—were created, and are run, using Hunch. Try Hunch at hunch.tools.

LinkedIn Rewind, launched in December 2024, helped over 300,000 professionals create personalized year-in-review posts about their 2024 LinkedIn activity. While Rewind was a one-time tool for year-end reflections, Coauthor builds on that technology to help professionals regularly create engaging social posts that truly sound like them.

Coauthor quickly analyzes your online presence, and then walks you through your professional background, writing style, goals, audience, and positioning to build your “Professional Signature.”

Within minutes, you’ll see tailored content ideas and posts crafted authentically in your voice, ready for you to review and share.

Your Professional Signature is Coauthor’s deep understanding of who you are professionally, including your experiences, writing style, audience segments, and career goals. This signature helps Coauthor generate content that authentically represents you and your professional brand.

Coauthor learns your voice through multiple channels:

• Information you share during onboarding, including existing online writing
• Your interactions with the platform (how you refine posts)
• Any additional writing samples you provide

No. Unlike traditional AI tools, you don’t need to craft perfect prompts. Simply share your thoughts in a quick note, and Coauthor handles the structure, tone, and formatting. No prompt engineering required.

While Coauthor works hard to ensure accuracy, no AI system is perfect. That’s why we show you the sources we’ve consulted for each claim and encourage you to review them. You always maintain full editorial control—if you spot something that doesn’t seem right, you can easily edit the post, provide additional context, or remove claims that don’t align with your expertise. We’re continuously improving our fact checking capabilities based on user feedback.

Currently, Coauthor is available through our web application, optimized for both desktop and mobile browsers.
