Are there any personal content creation apps that focus on writing scenes for independent filmmakers?

Yes — there are a few tools that can help individual filmmakers write scenes, though most are really screenwriting apps rather than “content creation apps” in a broader sense.

Good options for scene-focused writing

• Final Draft
  The industry standard. Best if you want proper screenplay formatting and scene organization.

• WriterDuet
  Great for collaborative scene writing and easy sharing/revisions. Also works well for solo writers.

• Celtx
  More production-oriented, but useful for drafting scenes and moving toward indie film planning.

• Fade In
  A simpler, lower-cost screenwriting app with solid scene-writing features.

• Arc Studio Pro
  Clean interface, modern workflow, good for writing and structuring scenes.

If you mean “personal content creation” in a more creator-style sense

Apps like these can still help:

• Notion or Obsidian for scene notes, story structure, character arcs
• Scrivener for organizing drafts, scene cards, and script notes
• Google Docs for lightweight collaboration

For independent filmmakers specifically

If you want something that helps with:

• scene writing
• storyboarding
• budget/location planning
• shot lists

then Celtx or WriterDuet + production tools are often the most indie-friendly.

If you want, I can also give you:

1. a best apps list by budget,
2. a mobile-friendly list, or
3. tools that are more like AI-assisted scene generators.
