Write your novel, short stories, comic scripts or screenplays. Understory connects the details and asks thoughtful questions, helping you see what needs another look.
The AI reviews. You write.
Every word remains yours.
Explore story arcs and characters together. Switch between the order on the page and the order events happen.
Choose a thread to follow it through your story.
Try the timeline with our fictional story, The Last Letter. Dates that are unclear stay unplaced.
Move between chapters and scenes. Keep notes to yourself, and review feedback in the margin.
This preview uses sample text. In Understory, you write and edit your own story. Notes to self are never shown to reviewers and are left out of exports by default.
Understory points to the passage and asks. Choose an answer or explain in your own words. You stay in control.
Ten years earlier, Theo had promised June that he would wait for her answer. He folded the note carefully and put it in his coat.
That afternoon, June stood at the kitchen door. “You kept it for eight years,” June said.

A fictional, browser-only demonstration. Nothing you enter here is sent or saved.
Each question points back to the relevant passage.
For an unresolved thread, “That is deliberate” tells every later review you meant it.
Understory never writes or changes a word of your story.
Understory reviews changed scenes when you ask. It never changes the words you’ve written.
Story facts link to the words behind them. When something is unclear, Understory asks.
Call the parts what your story calls them: chapters, stories, issues or acts. Comic scripts and screenplays get the same careful review as prose.
Join books, volumes or episodes into a series. Lore, story arcs and questions span every one of them.
Export to Word, PDF, Markdown or plain text, and screenplays to Final Draft or Fountain. Bring in a co-author, or invite reviewers to leave notes in the margin.
Writing is free, for as long as you like. For less than a coffee a week, Understory reads every page you write and keeps the whole story in view.
