# Power-Up #2: Plannotator — Visual Plan Review for Coding Agents

In the first entry of this series, I discussed [**Amp**](https://blog.productsway.com/power-up-1-amp-opinionated-ai-that-fits-real-developer-workflows): an opinionated AI that integrates naturally into real developer workflows. This time, I want to highlight a tool that solves a *specific but painful problem* when working with AI coding agents: **reviewing plans efficiently.**

Meet [**Plannotator**](https://plannotator.ai/).

## **The Pain: Reviewing AI Plans in the Terminal**

If you use Claude Code or OpenCode, this will feel familiar:

* The agent prints a long plan in the terminal
    
* You’re asked to approve or reject it
    
* Giving precise feedback means retyping the context manually
    
* Referencing exact sections is awkward
    
* Collaboration is basically nonexistent
    

This workflow *technically works*, but it doesn’t scale, especially when you’re running **multiple agents in parallel**.

## **What Plannotator Does Exceptionally Well**

Plannotator moves plan review **out of the terminal** and into a focused, visual interface.

Instead of replying with paragraphs of text, you can:

* Select *exact* parts of a plan
    
* Mark them for deletion
    
* Add comments, image
    
* Suggest replacements
    

Feedback becomes **precise, contextual, and fast**: much closer to [reviewing a pull request](https://share.plannotator.ai/#hVXbbtw2EP2Vwe6L40QbO0lf_GZ448KojbhJ_NQtoFlqtCKWGrK8aL0o-u_FUNRejAJ9IzlzztzOSH_P3OxmNodng3wDt00DT7ilVhuCnY4dpAFa62FJ5H6maP2KVzyfw68WzYrvPGEkQKgnUA3RQtC9M7rdg7J9bxkaGshY1xNHiBi2AVLQvIHYEfS2Ic9Qp0Gg1uRoz_vYWQaHaosbgh4ZNyTwRQl_Z_seuQkS7YGVSQ2NlvmEfS7YpwMWLtJQrTFQ827FFdQ9bgkacqGGj-WmOUQ0poYKHsbjRCd-U0PO0VVyDUYSzEs-wQmsVBDeQJQhZEHcyUF6rFB1hxLuveVI3MCSHHFDrPQpRcmyaovbabrseglxghopb435H7Y3da9t7KYqkBuYguUCJtblyWCnkRyZjeYolN8Tg09tmx_Ig2UIXn08d6xa_XrmnJuNKVqxHH1b63vMtPf5NOWobFMUK-ijv-pIbSdiCQTvC8domkr5npgnTd46Z7TCqC0fiXziakdrofoR0UfY0RpyQS0qgotDg97DGtWW-FRmAlZGH8F3jw9H8JTDS9RGx_1_tLIj4zK4szvAAbXBtaG8X6PjSPB7wkxgW3jULR3xA_GQ9TYubBpg0D4mNEA8aG9ZRlh2614byos1OmeS43pX8ISa33wkRDAR_YZiSQV-oz0sKegNw5KUDtpyNl0v4PLyJeQURHmEjWTrtLu8vMmPAa6vquurq1doMYhcRH0dBkBYU5QHT8GagfyKPwnbDzJtpSxH1EzNlIfQfUXVlTt0yI3UpWMAu2Nwnjz9lXTQUbbhszDJNvrca4j0GoVCUq3n8zq3mjiG_H1qrEpyKxL5ksHehlA5g1HkBbhDT0whHFhcFurn-rTu8lhnVmd9xHWWQOni11fsnSF4CbjJKqnreo2hW_EcvjFVUfcEgWJyK367zJnibEN31m9bY3fFtwh69HvUHDVvimlayByw5PIgmRyKhm--kQlcLyZNnStCWU9HSXxa5D_L4Vs6HJQLFxLrQ1nJd3kQ4uoTn6j7y_g4TiaTrviXBfykEE_iWr8NEtiTima_4tmHGc5u_vjzn38B) than chatting with a bot.

## **Designed for Parallel Agent Work**

This is what sold me. When one agent finishes generating a plan, Plannotator automatically opens the browser for review. While another agent is still running, you can:

* Review and approve a plan immediately
    
* Send feedback without blocking other work
    
* Continue coding while agents run in parallel
    
* Stop polling terminals just to see who’s done
    

It fits naturally into real-world, parallel workflows.

## **Local-First, Zero-Cost, No Trust Issues**

Plannotator is refreshingly developer-centric:

* Runs entirely **locally**
    
* No backend
    
* No network requests
    
* No accounts
    
* No hidden cost model
    

Plans never leave your machine. Even sharing works without infrastructure, plans, and annotations is compressed directly into the URL. No database. No third parties.

## **How It Works**

When your AI agent finishes planning, Plannotator:

1. Opens the Plannotator UI in your browser
    
2. Lets you annotate the plan visually (delete, insert, replace, comment—even on images)
    
3. **Approve** → the agent proceeds with implementation
    
4. **Request changes** → annotations are sent back as structured feedback
    

No manual copying. No context loss.

If you’re serious about AI-assisted development, especially with Claude Code or OpenCode, Plannotator is one of those small tools that quietly make your workflow much better.
