Novlr's solo core is compact: build a local-first novel writing app with fast capture, full-text search, backlinks, tags, and Markdown export. A competent builder can reach a useful personal version in one sitting, while the paid product mainly wins on polish, sync, importers.

Build verification: not recorded. How we judge buildability

What you give up

  • conflict-safe multi-device sync
  • mature importers and exporters
  • collaborative editing and sharing
  • native mobile clients

Why people still pay

Novlr: People pay for a writing surface they trust for years, plus migration tools, sync, and tiny interaction details that disappear into habit.

Your build guide

The stack, security requirements, and agent rules for a focused replacement.

Before you start

  • Node and the Rust toolchain, a supported desktop build environment and an explicitly selected data folder. Remote sync is outside the initial scope.
  • Implementation components: Tauri, React and TypeScript for the desktop interface with a narrowly scoped Rust filesystem bridge. SQLite for structured state and search; user-owned files for original documents and attachments.
  • Scope boundary: conflict-safe multi-device sync; mature importers and exporters

Implementation plan

1

Phase 1

Scope and fixtures. Implement this bounded workflow: Write a novel in a focused editor, arrange chapters and scenes and track a user-chosen writing goal without interrupting drafting. Export a selected manuscript order with its research notes separate. Record prerequisites, select representative user-owned fixtures and document the unsupported features: conflict-safe multi-device sync; mature importers and exporters

2

Phase 2

Durable model. Model novels, chapters, scenes, writing sessions, optional word goals and manuscript revisions Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Session statistics are derived from saved edits rather than keystroke surveillance; reordering a chapter never overwrites scene content.

3

Phase 3

Complete the first useful path. Implement the workflow's input, review and output interface, with clear controls and explicit empty/error states. Save edits atomically with stable IDs and revision history. Detect external file changes and offer a conflict copy instead of last-write-wins data loss.

4

Phase 4

Permissions and integration failure. Limit Tauri capabilities to selected folders and commands. Render imported content without executable HTML, and never expose arbitrary shell execution to the webview. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.

5

Phase 5

Portable handoff. Provide a portable folder export with a JSON manifest and original files. Restore to a separate folder; rebuild disposable indexes from sources. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.

6

Phase 6

Acceptance scenarios. Recover an interrupted draft from the last atomic save; compiling selected chapters yields the same order and headings shown in the binder. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

WORKING SLICE
Write a novel in a focused editor, arrange chapters and scenes and track a user-chosen writing goal without interrupting drafting. Export a selected manuscript order with its research notes separate.

Build this scoped Novlr-inspired workflow with a documented data model and visible failure states.

Architecture
- Tauri, React and TypeScript for the desktop interface with a narrowly scoped Rust filesystem bridge.
- SQLite for structured state and search; user-owned files for original documents and attachments.

Prerequisites and limits
Node and the Rust toolchain, a supported desktop build environment and an explicitly selected data folder. Remote sync is outside the initial scope.
Outside this release: conflict-safe multi-device sync; mature importers and exporters

Data model and correctness
novels, chapters, scenes, writing sessions, optional word goals and manuscript revisions
Invariant: Session statistics are derived from saved edits rather than keystroke surveillance; reordering a chapter never overwrites scene content.
Save edits atomically with stable IDs and revision history. Detect external file changes and offer a conflict copy instead of last-write-wins data loss.

Security and privacy
Limit Tauri capabilities to selected folders and commands. Render imported content without executable HTML, and never expose arbitrary shell execution to the webview.

Recovery and export
Provide a portable folder export with a JSON manifest and original files. Restore to a separate folder; rebuild disposable indexes from sources.

Implementation order
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Write a novel in a focused editor, arrange chapters and scenes and track a user-chosen writing goal without interrupting drafting.

Acceptance
Recover an interrupted draft from the last atomic save; compiling selected chapters yields the same order and headings shown in the binder.
Use real source data or clearly labeled fixtures. Explain unsupported input and provider failures; do not fabricate analytics, delivery receipts, accuracy claims or security guarantees.

Optional agent guidance
Optional external skill: [vercel-react-best-practices](https://github.com/vercel-labs/agent-skills/blob/main/skills/react-best-practices/SKILL.md) — Improve React and Next.js data fetching, rendering, bundle size and server performance. Review its instructions and compatibility before use; it does not grant deployment, data-access or publication permission.
Optional external skill: [web-design-guidelines](https://github.com/vercel-labs/agent-skills/blob/main/skills/web-design-guidelines/SKILL.md) — Review web interfaces for accessibility, keyboard focus, forms, navigation and interaction quality. Review its instructions and compatibility before use; it does not grant deployment, data-access or publication permission.
Optional external skill: [sharp-edges](https://github.com/trailofbits/skills/blob/main/plugins/sharp-edges/skills/sharp-edges/SKILL.md) — Review security-sensitive APIs and configuration for dangerous defaults and easy-to-misuse interfaces. Review its instructions and compatibility before use; it does not grant deployment, data-access or publication permission.
Project rule — data model: novels, chapters, scenes, writing sessions, optional word goals and manuscript revisions
Project rule — preserve this invariant: Session statistics are derived from saved edits rather than keystroke surveillance; reordering a chapter never overwrites scene content.
Project rule — acceptance evidence: Recover an interrupted draft from the last atomic save; compiling selected chapters yields the same order and headings shown in the binder.

Questions about Novlr

Can you build your own Novlr with AI?

The verdict is yes for the scoped workflow. Novlr's solo core is compact: build a local-first novel writing app with fast capture, full-text search, backlinks, tags, and Markdown export. A competent builder can reach a useful personal version in one sitting, while the paid product mainly wins on polish, sync, importers.

What does the Novlr build prompt cover?

The prompt starts with this scope: Write a novel in a focused editor, arrange chapters and scenes and track a user-chosen writing goal without interrupting drafting. Export a selected manuscript order with its research notes separate. Full-product capabilities excluded from the comparison include: conflict-safe multi-device sync; mature importers and exporters; collaborative editing and sharing. Follow the implementation plan and its prerequisites before expanding the build.

How do I use the prompt, AGENTS.md and agent skills?

Start with the Novlr prerequisites and stack, then copy the prompt into your coding agent. Save the project rules as AGENTS.md in the project root. Linked skills are optional packages or source instructions for specific tasks; review their current contents and install only those matching the chosen stack. A skill does not supply API credentials or verify the finished app.

How long will this Novlr project take?

The catalogue estimate is one sitting for the limited scope. Setup, integration approvals, debugging, deployment and ongoing maintenance can add time. This is an estimate, not a delivery guarantee.

What would I give up by replacing Novlr?

conflict-safe multi-device sync; mature importers and exporters; collaborative editing and sharing; native mobile clients. Novlr: People pay for a writing surface they trust for years, plus migration tools, sync, and tiny interaction details that disappear into habit.

What can I use instead of building Novlr?

Reedsy Studio: A browser manuscript studio with cloud backup, one real goal and no invoice. Check each option's license, hosting needs and feature limits.
