Description
A Markdown editor for human and coding-agent collaboration on planning, design, and spec documents. The agent drafts the plan and raises open questions as inline comments, and the human reviews, answers, and edits in a turn-based loop until the document is complete. It installs as an agent skill for Claude Code, Codex, and Pi, and ships a desktop editor alongside a command-line interface.
Validate Claims
Install the CLI globally with npm install -g inplan, then in Claude Code give a planning request. The inplan skill triggers, creates a new .plan.md, opens its editor, and drafts the plan with the agent's open questions as inline comment threads — answer them and the agent revises in a turn-based loop. The CLI and editor are the entire free, open-source product; no account is needed.
Specific Task(s)
Ask Claude Code to plan a small feature from scratch — for example, "plan a tic-tac-toe game."
Specific Prompt(s)
plan a tic-tac-toe game
Then review the drafted plan in the inplan editor, answer the inline question comments, and (optionally) switch the agent to build mode to implement it.
Additional Comments
Disclosure: the desktop editor's Electron binary is downloaded at install time via npm postinstall. inplan has opt-in, default-off telemetry (PostHog). An optional paid cloud (inplan.ai) adds live collaboration but requires explicit sign-in; the free open-source CLI and local editor work without it.
