Features

Writing, AI assistance, and version history

Writing and games share lore, creative presets, and Skills. Project files live on your own device, with changes you can inspect, undo, and restore.

Fiction writing

Create or import a novel, edit Markdown, manage outlines and chapter plans, track writing progress, and add manuscript comments.

Creative Agents

Choose Native, Codex, or Claude Code to work with selections, project files, images, and lore.

Presets and Skills

Reuse narrative styles, image styles, and rules. Extend Agent workflows with Skills.

Local versions

Save milestones, inspect file diffs, restore earlier content, and review or undo Agent edits.

Lore library

Organize characters and worldbuilding

Organize characters, places, rules, and media with custom categories, document-style indexes, @ references, and backlinks. Use the same lore for writing and games.

  • Each record supports multiple images, audio, and a cover
  • Connect records with @ references and backlinks
  • Provide grouped context to Writing and Game Agents

AI assistance

Use Agents for creative tasks

Use the built-in Native runtime, Codex, or Claude Code. Agents can continue writing, check lore, edit files, and handle project tasks in the workbench.

  • Work with selections, project files, images, and lore
  • Multiple conversations and pause/resume; Native can delegate to Subagents
  • Inspect diffs, review changes, or undo edits

Install Codex or Claude Code on the device running Denova. The interface shows which operations each engine supports.

More tools

Images, automation, resources, and extensions

Use these tools in the Denova app. Writing and games share assets and settings; the workbench handles project tasks and extension development.

Image creation

Generate covers, chapter illustrations, backgrounds, and character art. Supports OpenAI, Grok, Seedream, Gemini Image, ComfyUI workflows, and custom endpoints.

Automation

Trigger reviews, writing, or custom tasks by schedule, chapter batch, or semantic condition, or run them manually. Keep the device hosting Denova running.

Resource center

Preview and selectively import presets, Skills, lore, plugins, and games from GitHub or local ZIPs. Combine exports, track sources, review updates, and restore backups.

Plugins and custom games

Plugins provide Agent tools, commands, and panels. Games define their own interface, gameplay, and saves. Create, build, preview, and export from the workbench.
