Context

CodeSpring — Visual mind-mapping tool that turns app ideas into PRDs and kanban tasks for AI coding agents. It currently costs $53/mo.

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.

This brief describes a focused, single-operator replacement for the part of CodeSpring that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

What you are building

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.

Build the focused developer workflow you use repeatedly, with local configuration.

A responsive interface with real empty, loading, success, and error states.

Requirements

Data and integrations

OpenAI/Anthropic API key.

Each of these needs a real account, credential, or quota. Set them up before writing feature code.

Non-functional

Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.

Security: server-side secrets, validated input, and no credentials in the client bundle.

Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.

Portability: the operator can export their data and leave without losing it.

Implementation brief

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.

Delivery standard

Inspect the repository first, then write a short implementation plan before writing code.

Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.

Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.

Include responsive layouts plus genuine empty, loading, success, validation, and failure states.

Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.

Add structured logs around every external call and return actionable errors without leaking sensitive details.

Write unit tests for the core logic and one automated test of the main user journey.

Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

Acceptance criteria

A clean install starts the app using only the README and .env.example.

The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.

Invalid input, missing configuration, provider failure, and an empty database each have a usable state.

The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.

Tests, type checking, linting, and a production build all pass with no ignored failures.

No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

Non-goals

Do not build these, and do not claim to have replaced them:

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.

What you still own after launch

Secure credentials, rotate secrets, and handle provider rate limits.

Run migrations, backups, restores, and dependency updates.

Test the critical journey after every model, API, or hosting change.

Monitor failures and fix the edge cases a first prompt will miss.

Maintain every third-party integration as APIs and OAuth rules change.

Risk

Operational risk. The code is achievable; dependable data, integrations, and ongoing operations are the real cost.

Editorial confidence in this assessment: medium. No reviewed project implementation is linked yet.

Existing alternatives

Before building, compare these checked options:

AFFiNE — Whiteboard-plus-docs workspace you can use to map features and write specs by hand

Prior art

Working open-source software you can read, fork, or borrow from before starting:

excalidraw — open-source canvas for mapping ideas visually

BMAD-METHOD — open-source agentic planning framework that generates PRDs and task breakdowns for coding agents
