AgentPlan: in-terminal workspace for reviewing agent plans

Expand each AI CLI session into a visual workspace for notes and plan review

Problem

As AI takes on more implementation, developers focus more on plans and reviews, but running multiple AI CLI sessions in a terminal mixes plans, notes, and context. Going back to annotate a plan or compare options means digging through messy scrollback.

Solution

Expand each AI CLI session into its own workspace inside the terminal, with plans, notes, and output in separate panes. Users can annotate a plan directly, compare options, and keep their existing CLI habits without breaking the workflow.

Users

Heavy users of Claude Code, Codex, and similar AI CLIs; tech leads who switch between sessions to review plans

MVP

Create a dedicated view per AI CLI session; split panes for plan and output; inline notes next to plans; fast session switching; preserve existing CLI shortcuts

Revenue

Personal subscription, team seats for shared plan review and export, open-source community edition for acquisition

Why now

The AI CLI boom makes multi-session review a daily task, yet terminals weren't designed for plan review, leaving a clear UX gap
