Marketing, Hooks & Social Content

TropeFinder

What it does: TropeFinder reads a manuscript or chapter and extracts the marketable tropes, BookTok-style hook angles, Instagram aesthetic ideas, and Substack/newsletter teaser angles.

Best used when: you know what your book is about, but you are not sure which reader-facing tropes, vibes, and marketing angles should lead the sales copy.

Using TropeFinder in the Suite

  1. Open the Darkling Suite from the classroom link.
  2. Select the active book or project.
  3. Go to Marketing, Hooks & Social Content and open TropeFinder.
  4. Choose your AI engine and confirm your API key is entered.
  5. If the Suite Brain already has a manuscript loaded, TropeFinder may show it as ready from the Suite Hub.
  6. If no manuscript is loaded, upload the manuscript file inside TropeFinder.
  7. Choose the closest Genre Focus.
  8. Choose the target platforms you care about.
  9. Click Analyze Manuscript.

The Suite version is best when you want the analysis to sit beside the rest of the book’s project data.

Using TropeFinder Standalone

  1. Open the standalone TropeFinder link provided in the classroom.
  2. Select your AI engine and paste your API key if needed.
  3. Upload a manuscript, chapter, or excerpt. Supported files include .txt, .md, .docx, .epub, and .pdf.
  4. Choose the closest Genre Focus.
  5. Select the platforms you want ideas for: TikTok/BookTok, Instagram, and/or Substack.
  6. Run the analysis and review each tab before copying anything into another tool.

The standalone version is best for quick trope discovery, a single book audit, or testing a chapter before the full manuscript is ready.

What to Upload

TropeFinder can analyze a full manuscript, but it can also work from a chapter or excerpt if that section contains the book’s core promise.

  • Full manuscript: best for complete trope extraction and launch positioning.
  • First 3-5 chapters: useful when you want to understand the book’s opening promise.
  • A high-tension chapter: useful for discovering social hooks around a specific emotional beat.
  • A cleaned excerpt: useful if the full file is messy or still changing.

If your file is very long, the tool may analyze the most relevant portion rather than every word. That is normal for speed and token limits.

Genre Focus

The Genre Focus keeps the output pointed at the right readers. Choose the shelf you would actually sell the book on, not just the vibe you like most.

  • Romance options: contemporary, dark romance, paranormal, monster, why choose/RH, super spicy, and several MM options.
  • Fantasy options: high fantasy, fantasy reverse harem, dark academia, and sci-fi/dystopian.
  • Historical options: historical romance, historical mystery, and historical fiction.
  • Mystery/suspense options: cozy mystery, thriller, and mystery.
  • YA option: useful when age category matters to positioning.

Platform Choices

  • TikTok/BookTok: second-person POV hooks and short text-on-screen angles.
  • Instagram: aesthetic, vibe, carousel, and visual-story ideas.
  • Substack: more intimate teaser angles, behind-the-scenes framing, and curiosity-gap newsletter ideas.

You can keep all three selected for a broad marketing pass, or narrow the platforms if you only need one kind of output.

What You Get Back

  • Core Tropes: 4-5 major reader-facing tropes with short explanations.
  • TikTok Hooks: BookTok-style hook concepts written in second person.
  • Insta Vibe: visual/aesthetic content ideas and story angles.
  • Substack Teasers: intimate curiosity-gap angles for emails or essays.

These are marketing assets, not a literary analysis. The point is to help readers recognize why the book is for them.

Recommended Workflow

  1. Upload the cleanest version you have. The tool can read drafts, but cleaner files produce cleaner positioning.
  2. Choose the real genre focus. Do not ask for dark romance output if the reader promise is actually cozy fantasy.
  3. Read Core Tropes first. Decide which tropes are central and which are only background flavor.
  4. Copy only the angles that match the book. If a result overstates the heat, danger, or romance, do not use it as-is.
  5. Send the strongest trope/hook pair forward. Use it in HookHero, OmniSqueeze, TeaserPro, Amazon copy, or email sequences.
  6. Rerun after major edits. If the manuscript changes, the marketable promise may change too.

How to Use the Results

  • For blurbs: use the top 2-3 tropes and the strongest central conflict.
  • For ads: use the most instantly recognizable trope, not the most complicated one.
  • For BookTok: use a hook that creates an immediate “wait, what?” question.
  • For Instagram: turn the vibe ideas into quote graphics, carousels, mood boards, or reels.
  • For newsletters: use the Substack teaser as an email opening, then write the rest in your own voice.
  • For metadata: use trope language carefully. Metadata should be searchable, not stuffed.

Common Fixes

  • The tropes feel wrong: check that the Genre Focus matches the actual book.
  • The output is too vague: upload a stronger excerpt or a cleaner manuscript file.
  • The hooks oversell the book: keep the premise, but soften the promise so it does not bait the wrong reader.
  • The Instagram ideas are too aesthetic: pair the visual vibe with a real conflict or trope.
  • The Substack teasers sound too formal: rewrite them as if you are telling a reader why you cannot stop thinking about the book.
  • Too many tropes appear: choose the ones that drive the story, not the ones that merely appear once.

Best Pairings

  • HookHero: turn the best trope angle into sharper hooks.
  • OmniSqueeze: multiply one trope-forward hook across platforms.
  • TeaserPro VN Studio: turn a trope/hook combo into carousels, captions, visuals, or video.
  • Brand DNA Generator: connect recurring tropes to the author brand and reader promise.
  • A+ Content Builder: use the clearest trope set in comparison charts and sales-page modules.
