Can AI replace Linearity Curve?

The visible vector design loop is buildable, but a credible replacement needs more than the first screen. Linearity Curve earns its keep through editor polish, assets, algorithms, so expect a weekend or multi-day build and a narrower personal scope.

01What it costs

PlanMonthlyBilled yearlyWhat you get
FreeFreeFree50 lifetime AI credits, 1 basic brand kit and 5 GB storage.
Pro$30$25/mo250 AI credits/month and 100 GB storage per editor.
Business$80$65/mo500 AI credits/month and 500 GB storage per editor.
Enterprise——Custom organisation-wide shared credits, SSO and security; public price is not listed.

Hidden costs: Pricing is per editor. Education customers can receive 58% off yearly Pro; extra usage beyond included AI credits can require an upgrade or additional purchase.

02Could AI build it for you?

The core job: Build a focused local vector design editor with import, a small set of transformations, undo, and standards-based export.

What a working version needs:

  • desktop development machine
  • Node.js 22 and Rust toolchain
  • sample user-owned assets

Useful boundary case: the first 60 percent of Linearity Curve is approachable, but operating the last 40 percent is the real subscription.

03What you'd give up

  • cloud collaboration and mobile apps
  • pixel-perfect professional tooling
  • large template and asset libraries
  • color-management edge cases

Linearity Curve: Creative users pay for speed, output fidelity, nondestructive editing, and years of edge-case work hidden behind direct manipulation.

05The build prompt

Paste this into an AI coding tool (such as Claude, ChatGPT, Lovable or Replit) to build your own version.

prompt.txt
Build a deliberately narrow personal substitute for Linearity Curve, not a full clone.
Use exactly this stack: Tauri 2 + React + TypeScript + Canvas API.
Primary job: Build a focused local vector design editor with import, a small set of transformations, undo, and standards-based export.
Start from an empty folder and create the complete working project.
Make the default mode single-user and private.
Store user data locally unless the core job requires the declared self-hosted database.
Do not add analytics, telemetry, ads, or third-party accounts.
Put every secret and external credential in .env and provide .env.example.
Use realistic sample data that is clearly labelled and easy to delete.
Implement the smallest polished interface that completes the core loop end to end.
Include clear empty, loading, validation, success, and failure states.
Add import and export so the user is not trapped in the app.
Use accessible keyboard navigation, labels, focus states, and sensible contrast.
Validate untrusted input and never log secrets or private file contents.
Deliberately exclude these paid-product advantages: cloud collaboration and mobile apps; pixel-perfect professional tooling; large template and asset libraries.
Do not fake integrations, network effects, proprietary data, model quality, compliance, or security claims.
Where an external API is optional, keep the app useful without it and explain the degraded mode.
Write focused unit tests for the data model and the most important workflow.
Add one end-to-end smoke test that proves the core loop works.
Create a README with setup, permissions, architecture, data location, backup, and limitations.
Add scripts for install, development, test, build, and a production-style local run.
Run the tests and build before finishing, then fix errors rather than merely describing them.
