Can AI replace CodeSpring?

The core loop, a mind map that turns feature notes into PRDs and kanban tasks fed to a coding agent, is just structured prompting and file generation, well within reach of a one-shot build. What's missing is the polish: the visual mind-map canvas, MCP/CLI integrations with Claude Code, Cursor and Codex, and the docs search. A DIY version gets you most of the value but with a rougher UI and manual glue between the planning docs and your agent of choice.

02Could AI build it for you?

The core job: A local app where you map features on a canvas, write notes per feature, and generate a PRD + task list file that you feed to your coding agent.

What a working version needs:

  • OpenAI/Anthropic API key

Planning-layer tool, not a hosted app itself; value is mostly in agent integrations and UI polish.

03What you'd give up

  • polished drag-and-drop mind-map canvas
  • MCP server integration with Cursor/Claude Code/Codex
  • semantic docs search
  • hosted kanban sync across devices
  • prebuilt skills library

Non-technical builders pay for the guided, visual workflow and the fact it already talks to Cursor, Claude Code and Codex out of the box, rather than assembling their own prompt templates and task tracker.

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 me a local-first app-planning tool in Next.js.
Stack: Next.js + TypeScript, SQLite via better-sqlite3, Tailwind for UI. No auth, single user, runs on localhost.
Core loop:
1. A canvas page where I can add draggable "feature" nodes (title + free-text notes), connect them with lines, and save the layout to SQLite.
2. A "Generate PRD" button per feature that calls the Anthropic API (key from .env) with the feature notes and produces a structured PRD (problem, scope, out-of-scope, acceptance criteria) saved as a markdown file in /docs.
3. A simple kanban board (To Do / In Progress / Done) auto-seeded with tasks parsed from each generated PRD, editable by drag-and-drop.
4. An "Export" button that zips all PRD markdown files plus a tasks.json for dropping into any coding agent's context folder.
Out of scope: multi-user accounts, real-time collaboration, MCP server, mobile app, billing.
Include a README explaining setup, the .env variable needed, and how to point Claude Code/Cursor at the exported /docs folder.
