Plannotator made plan review popular: when your agent leaves plan mode, the plan opens in your browser, you annotate it and send it back. AgentsRoom does the same review inside the app that runs your agents, in the agent's own pane, with the history on your account and the same card on your phone.
Below: what Plannotator does, checked on its website and its repository on 31 October 2026, where each tool is ahead, and when you should keep Plannotator.

The plan review card in AgentsRoom: the plan opens above the agent's input box, next to its terminal, not in a separate tab.
Facts checked on 31 October 2026 on plannotator.ai and in the backnotprop/plannotator repository on GitHub.
Plannotator plugs into your agent's plan step with a hook or a plugin, depending on the CLI. When the plan is ready, a local review page opens in your browser: you mark passages for deletion, comment on them or write a replacement, then approve or send the plan back as structured feedback. Every revision is kept, with a diff between versions.
It also reviews code like a pull request: your local changes, or a GitHub or GitLab pull request opened by its URL, with line comments, suggested code and optional AI reviewers. Commands annotate a markdown file, a folder, a URL, an HTML page or the agent's last message.
Plannotator is free and open source under the MIT or Apache 2.0 license, with close to 10,000 stars on GitHub. Review data stays on your machine by default and it collects no usage telemetry. Plans can be shared by link, and Workspaces, a hosted layer for teams, is on a waitlist.
Claude Code, Codex, GitHub Copilot CLI, Gemini CLI, OpenCode, Pi, Amp, Droid and Kiro, plus a VS Code extension and saving to Obsidian and Bear. A newer Inbox gathers your agents' questions, plans and reviews in one local window.
Both tools turn a plan into a document you annotate. Where that document lives changes how you work.
You keep your terminal and your agent exactly as they are. At the plan step, Plannotator opens its review page in your browser, or in VS Code, you annotate, and the agent gets your decision. It is focused, light, and reaches many CLIs.
In AgentsRoom each agent already lives in a pane of the app, with its terminal, its status and its input box. The plan opens right there. With four agents planning at once, each plan waits in its own pane, and the same card follows you to your phone.

Plannotator stops at the review, by design. AgentsRoom is where the agents run, so the review is one step in a longer loop.
Run Claude, Codex, GitHub Copilot CLI, Cursor and 13 other agent CLIs side by side, each in its real terminal with a live status. When several agents plan at once, each plan waits in its own pane.
When an agent needs a decision rather than a plan approval, it asks in a card with clickable options, docked where the plan card opens. Answer from the desktop or the phone, even from the lock screen for a quick choice.
The iOS and Android apps show every agent, push a notification when one is waiting for you, and open the same plan card: tap a paragraph, annotate, approve.
Once the agent has worked, review its diff file by file, comment on any line and send it all back as one message. When several agents share a branch, filter the changes by agent.
Start agents on a schedule or on an event: review every new pull request, triage new GitHub issues into the backlog, run the tests every night with a report in the morning. Pick a recipe, check the draft, save.
Tickets that hand work to agents, 14 specialized roles, agent teams that pass work from Dev to QA, and a project memory every agent reads.
Try the real interface in your browser: several coding agents in one window, each with its terminal, its status and its input box.
The desktop app, in Simple mode
On a phone the demo runs the real desktop app in its Simple interface mode: one project, its agents, one prompt. The full cockpit is on your computer.
An honest comparison says when to stay. These are the cases where Plannotator is the right tool and AgentsRoom is not.
Plannotator is released under the MIT or Apache 2.0 license and the local tool is free. AgentsRoom is not open source, and its free plan includes plan review but limits the number of projects.
Plannotator opens a GitHub or GitLab pull request from its URL, with line comments, suggested code and optional AI reviewers, and it handles GitButler, Jujutsu and Perforce. AgentsRoom reviews the local git changes of its own agents.
Plannotator catches the plan step of more CLIs, GitHub Copilot CLI, Gemini CLI and Pi among them. AgentsRoom catches it in Claude Code, Codex, OpenCode and Antigravity; with the other CLIs it runs, you use Annotate the last message.
If you are happy in your terminal and only want to review plans more comfortably, Plannotator adds exactly that, with nothing else to learn. AgentsRoom asks you to run your agents inside it.
Plannotator collects no usage telemetry or analytics. AgentsRoom sends anonymous usage events, which you can switch off in Settings > Privacy & data.
Plannotator shares a plan by link, encrypted for the larger ones, so a teammate can annotate it too. In AgentsRoom, plan history stays on your own account.
Your repositories, your agent CLIs and your subscriptions stay as they are.
Download it for macOS, Windows or Linux and add your project folders. Your CLAUDE.md and AGENTS.md files are detected automatically.
Open Claude Code, Codex, OpenCode or Antigravity in a pane and ask for a plan. Plan review is on by default.
Annotate, then approve or request changes. If Plannotator is installed in the same CLI, keep one review step active: the AgentsRoom one is switched off in Settings > Agent behavior.
