What Authors Say About co-Editor
“The folder system is perfect for organizing my chapters. And when I hit a wall, the AI chat helps me brainstorm plot twists. Best writing tool I've found.”
“I love the AI research feature. I can look up facts and references without leaving the editor. Plus the DOCX export is clean enough to send directly to my publisher.”
“Voice dictation changed my workflow completely. I speak my first drafts and let co-Editor's AI help me polish them. Much faster than typing everything.”
“I manage three book series in co-Editor. Nested folders keep everything organized — drafts, outlines, character sheets. The AI helps me stay consistent across 20+ chapters.”
