Idea Manager

English | 한국어 | 日本語 | 中文

v1.8+ users: im start now auto-updates on boot. If you're on an older version, run npm install -g idea-manager@latest once — after that, every future release is applied automatically.

Turn free-form brainstorming into structured task trees with AI-generated prompts.

A local-first task management tool for developers. Organize ideas into workspaces and projects, refine prompts for each task, and hand them off to AI agents. Built-in MCP Server enables autonomous AI agent execution. Cross-PC sync via Git.

Quick Start

npm install -g idea-manager
im start

Opens a native-like app window (Chrome/Edge --app mode). First run builds automatically. From v1.8.0, im start checks npm on boot and auto-upgrades when a newer version is available (IM_NO_AUTO_UPDATE=1 to opt out).

Core Workflow

Brainstorming → Projects / Tasks → Prompts → AI Agent Execution

Hierarchy

Workspace
├── Project A
│   ├── Task 1  →  Prompt

Task Status Flow

💡 Idea → 🔥 Doing → ✅ Done
                      🔴 Problem

Legacy statuses (Writing, Submitted, Testing) remain available and are shown as a dashed badge on pre-v1.6 tasks.

Features

Multi-Agent Support

Choose your AI CLI per project:

Agent	CLI	Description
Claude	claude	Anthropic Claude Code CLI
Gemini	gemini	Google Gemini CLI
Codex	codex	OpenAI Codex CLI

Select from the project header dropdown. Used for Watch mode and AI Chat.

Cross-PC Sync

Sync your data across machines via a private Git repository.

# First machine
im sync init          # Create/connect a Git repo
im sync push          # Export + push

# Other machines
im sync init          # Same repo URL
im sync pull          # Pull + import

Supports auto repo creation with GitHub CLI (gh).

MCP Server

Expose tasks to external AI agents via Model Context Protocol.

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "idea-manager": {
      "command": "npx",
      "args": ["-y", "idea-manager", "mcp"]
    }
  }
}

Claude Code:

claude mcp add idea-manager -- npx -y idea-manager mcp

MCP Tools

Tool	Description
list-projects	List all projects
get-project-context	Full sub-project + task tree
get-next-task	Next submitted task to execute
get-task-prompt	Get prompt for a task
update-status	Change task status
report-completion	Report task done

Watch Mode

Auto-execute submitted tasks with real-time streaming output:

im watch                          # All watch-enabled projects
im watch --project <id>           # Specific project
im watch --interval 30 --dry-run  # Preview mode

Note-Centric Editor (v1.6)

The task detail replaces the old separate "description + prompt" pair with a single rich Markdown note.

• CodeMirror Editor — Markdown syntax highlighting with distinct styling for headings, list markers (-, 1.), code, links, and quotes. GFM enabled (task checkboxes, strikethrough, tables).
• ⌘K AI Command Palette — Refine the selection or continue at cursor without leaving the note:
  • 이어서 써줘 (continue) · 이 부분 정리해줘 (tidy) · 할 일로 쪼개줘 (split into tasks) · 질문으로 바꿔줘 (to questions) · 요약해줘 (summarize) · Custom prompt
  • Result is inserted inline. Cancel mid-run; Undo within 30s of applying.
  • Runs on Sonnet without project context for ~7s typical latency.
• Context-Aware Autocomplete — Ghost text suggests multi-word phrases (up to 3 tokens). Corpus pulls from the current note, sibling tasks in the same project, and the project's brainstorm. Phrases sharing vocabulary with the current note are boosted, so related terms surface first. Tab accepts, Esc dismisses.
• List Auto-Continue — Enter continues bullets/numbers/checkboxes; Enter on an empty item exits the list.
• Copy as Prompt — One-click copy of the whole note formatted for pasting into Claude Code / another agent.

Workspace

• 3-Panel Layout — Brainstorming | Project Tree | Task Detail (drag to resize)
• Tab-based Navigation — Multiple projects open simultaneously
• File Tree Drawer — Browse linked project directories
• Brainstorming Panel — Free-form notes with inline AI memos
• Auto Distribute — AI analyzes brainstorming and distributes tasks to sub-projects with preview/edit modal
• Note Assistant — Per-task AI chat (formerly "AI Chat") for refining the note, with one-click insert into the note
• Quick Memo — Global scratchpad on dashboard for free-form notes (auto-saved)
• Morning Notifications — Daily macOS notification at 9 AM with today's tasks summary
• Dashboard — Active / All / Today / Archive views
• Keyboard Shortcuts — B brainstorm, N project, T task, ⌘K AI command palette, ⌘1/2/3/4 status (Idea/Doing/Done/Problem)

Data

• Local-first — All data in ~/.idea-manager/data/ (SQLite via sql.js)
• Zero native deps — Pure JavaScript, no C++ build tools needed
• Auto backup — Database backed up before each sync pull
• App mode — Opens in Chrome/Edge without address bar

Tech Stack

Area	Technology
Frontend	Next.js 16, React 19, TypeScript, Tailwind CSS 4
Backend	Next.js API Routes
Database	SQLite (sql.js, pure JS)
AI	Claude / Gemini / Codex CLI
MCP	Model Context Protocol (stdio)
CLI	Commander.js

Requirements

• Node.js 18+
• AI CLI (optional) — Claude CLI, Gemini CLI, or Codex CLI for AI features. Core task management works without it.

Troubleshooting

im command not found after install

Add npm's global bin directory to your PATH:

# Check the path
npm prefix -g
# Add to shell profile (~/.zshrc or ~/.bashrc)
export PATH="$(npm prefix -g)/bin:$PATH"

Port already in use

# Kill the process using the port
lsof -t -i :3456 | xargs kill -9    # macOS/Linux
netstat -ano | findstr :3456          # Windows (then taskkill /PID <pid> /F)
