Marginalia User Guide

Marginalia is an AI-powered manuscript analysis tool that helps writers improve their work through intelligent suggestions. This guide walks you through the full workflow: creating a manuscript, analyzing it, and reviewing suggestions.

Getting Started

When you first open Marginalia, you see the Your Manuscripts page. This is your home screen where all saved manuscripts are listed. If you have no manuscripts yet, you will see an empty state prompting you to create one.

You are presented with two options for adding content:

  • Paste text directly using the paste text mode.

The Editor

After loading your text, Marginalia opens the Editor view. The editor displays:

  • Toolbar — shows the manuscript title, source label, original and accepted word counts, and action buttons (Analyze, Export, Delete).
  • Document pane (left) — your manuscript text, divided into paragraphs.
  • Suggestions panel (right) — where AI suggestions appear after analysis.

Analyzing Your Manuscript

  1. Click the Analyze button in the toolbar. The Analyze Manuscript dialog opens.

  1. Select a Tone from the dropdown. Available tones include Professional, Narrative, Academic, Conversational, and Literary.
  2. Optionally enter Guidance to focus the analysis on specific aspects of your writing.

In this example, we select Narrative tone and enter "Fantasy role playing" as guidance.

Reviewing Suggestions

Once the analysis completes, suggestions appear in the right panel. Each suggestion is linked to a paragraph in your manuscript, indicated by numbered markers in the document.

The suggestions panel shows:

  • Summary counts — pending, accepted, and rejected suggestions.
  • Bulk actions — Accept All and Reject All buttons.
  • Filter tabs — All, Pending, Accepted (check mark), Rejected (X), and Modified (pencil).
  • Individual suggestion cards — each showing the paragraph number, status, and a summary of the feedback.

Expanding a Suggestion

Click a suggestion card or its expand arrow to see the full details:

  • Original text — the current paragraph text (shown with strikethrough).
  • Proposed change — the AI-recommended replacement text.
  • Action buttons — Accept, Reject, Modify, or re-Analyze.

Accepting a Suggestion

Click Accept on a suggestion to apply the proposed change. The document text updates immediately to reflect the accepted revision, and the word count adjusts in the toolbar.

Suggestion 1 accepted with updated text in the document

You can accept multiple suggestions individually. In this example, suggestions 1 and 3 have been accepted while suggestion 2 remains pending.

Other Suggestion Actions

  • Reject — dismisses the suggestion without changing the text.
  • Modify — lets you edit the proposed text before applying it.
  • Revert to Pending — undoes an accept or reject, returning the suggestion to pending status.
  • Analyze — re-runs the analysis on just that paragraph.

Re-Analyzing a Manuscript

You can run a fresh analysis on a manuscript that already has suggestions. This is useful when you have accepted some suggestions and want new feedback on the updated text.

  1. Open the manuscript in the editor. In this example, 2 suggestions have been accepted and 1 is still pending.

  1. Click Analyze in the toolbar. The Analyze Manuscript dialog opens, allowing you to choose a new tone and guidance.

  1. Configure the tone and guidance as desired, then click Analyze.

  1. Because the manuscript was analyzed before, a Replace Analysis? confirmation dialog appears. It explains that your accepted suggestions will be merged into the manuscript text and any pending suggestions will be discarded.

  1. Click Replace & Analyze to proceed. The accepted changes become part of the base text, and a new set of suggestions is generated.

The original word count now reflects the merged text, and all suggestions start fresh in the pending state.

Analyzing a Single Paragraph

Instead of re-analyzing the entire manuscript, you can re-analyze a single paragraph from within an expanded suggestion. This lets you try different tone and guidance settings on just one section.

  1. Expand a suggestion by clicking its card or the expand arrow.

  1. Click the Analyze button at the bottom of the expanded suggestion. The Analyze Paragraph dialog opens, pre-populated with the settings from the last analysis.

  1. Change the tone and guidance to explore a different editorial direction. In this example, we switch to Conversational tone and enter "Childrens story" as guidance.

  1. Click Analyze. A new suggestion is generated for just that paragraph and added alongside the existing suggestions. The paragraph now shows multiple suggestion markers, and the suggestion count increases.

You can repeat this process with different tones and guidance to compare multiple editorial perspectives for the same paragraph.

Managing Manuscripts

After analysis, your manuscript appears in the manuscript list on the home page, showing the title, date, suggestion count, and analysis status.
