Summary
Section titled “Summary”Whiteboard is an open-source app that helps developers understand changes made by an AI coding agent before approving a pull request. It maps the changes, shows a sequence diagram with links to the relevant code, and summarizes large functions while folding away tests and documentation. The video says Whiteboard runs locally, uses your own agent, and does not post anything to GitHub. Its value is judged by whether it helps users understand what they are about to merge.
Key points
Section titled “Key points”- Whiteboard creates a map of changes made by an AI coding agent.
- It shows a sequence diagram of the request flow alongside the code for each step.
- Clicking a step opens the relevant function in the code.
- The diff view folds away tests and documentation.
- Large functions are summarized as pseudocode to highlight changed logic.
- Whiteboard runs on your machine and uses your own agent.
- It does not post anything to GitHub.
- The video says Whiteboard is MIT licensed and comes from a company in YC’s winter 2026 batch.
Chapters
Section titled “Chapters”| Start | Chapter | Summary |
|---|---|---|
| 00:00 | Mapping an agent’s changes | Whiteboard maps an agent’s changes and links a request-flow sequence diagram directly to the relevant code. |
| 00:16 | Reviewing the changed logic | The diff view folds away tests and docs and summarizes large functions so reviewers can focus on what changed. |
| 00:32 | Local use and the goal of review | Whiteboard runs locally with your own agent, posts nothing to GitHub, and aims to help users understand what they are about to merge. |

Full transcript (original language)
Section titled “Full transcript (original language)”00:00 Your agent has changed 40 files. You’re about to approve the pull request, but could you actually explain what it did? This is whiteboard, a new open-source app that makes your agent draw a map of those changes and link straight into the code. A sequence diagram of the request flow streams and in the code next to each step as well. That’s not a mermaid block in chat. I click a step and it takes me into that function. Now I can follow the explanation and check it out without hunting through the files. Switch to the diff. Tests and docs are
00:32 folded away. Big functions are summarized as pseudo code. What’s left is the logic that actually changed. Instead of reading directions in a paragraph, I have a map and I can check where it actually leads to. Whiteboard runs on your machine uses your own agent and posts nothing into GitHub. It is MIT licensed from a company in YC’s winter 2026 batch. That’s what I judge whiteboard on. Not how good the map looks, but whether I understand what I’m about to merge.
