Ruthless Editor: review one passage Edited actual app captures and editorial guide cards. AI narration. Not an uninterrupted screen recording. This walkthrough follows a real Ruthless Editor analysis of the opening of Death Takes a Honeymoon by Kat Summers. The app captures are edited into steps, with narration added afterward. This is a short excerpt review, not a claim that the whole book has been edited. Begin with one passage and give the saved manuscript a useful name. Keep your original file separately. Browser saves belong to this browser, so export a backup if you want to move devices or protect your work before clearing browser data. Choose your writing provider and an available model, then enable Use saved connection. This run used OpenAI with the model shown on screen. Your key stays out of the demo. Analysis uses your provider account, and a longer manuscript can require more than one request. The editorial brief tells the model what matters. Here, the genre is supernatural romantic comedy. The instructions preserve Corvus's comic first-person voice, deliberate fragments, exaggeration, and the repeated phrase, Four days. Protected phrases add a firmer boundary: proposals overlapping those phrases cannot be accepted. Run the analysis, then check coverage. This passage contains ninety-nine words in one segment. The completed status means that segment was analyzed. It does not mean every sentence needs changing, or that every model suggestion is right. The actual response offered one punctuation suggestion. It replaced the parenthetical aside, lovely bones, that one, with em dashes. Use View source passage to read that line in context. Compare the original, replacement, and explanation before deciding. Accepting the proposal updates the edited draft. It does not overwrite the imported source. Undo decision restores the original wording and returns the proposal to pending. In this review, I then reject the change. The parenthetical pause already suits the narrator's voice. I add an author note explaining that choice. That is a valid editorial outcome. A suggestion can be reasonable and still be unnecessary for this passage. Preserve purposeful style rather than accepting changes simply to make the proposal count go down. Export the review report, edited draft, original source, and editable backup. These files serve different purposes. The report records decisions; the backup restores the workspace; the text exports let you compare the result outside the app. Original and edited text matched in this run because the only proposal was rejected. Read the final export before replacing anything in your writing project. Keep the current manuscript and your review history. The goal is a deliberate decision you can explain, with your source and your voice still under your control.
