Generate and watch a Lenzon explainer for a pull request without leaving VS Code. Lenzon turns a PR into a short narrated, animated walkthrough of what changed and why, so you can get oriented before reading diffs — and you can kick it off right from the editor with a single command.
What it does
- Detects the GitHub repository and current branch in your workspace.
- Runs
Lenzon: Explain this PRto generate a narrated, animated walkthrough for the branch's open PR — or a specific PR you enter — and plays it in a panel beside your code. - If a PR already has an explainer, it opens right away; if not, Lenzon generates one on demand.
- If a branch has more than one open PR, you pick from a list. You can also browse what Lenzon has already explained for the repo.
Getting started
- Install the extension.
- Run
Lenzon: Sign infrom the Command Palette (Cmd/Ctrl+Shift+P). A short device code opens in your browser; approve it while signed in to your Lenzon account. Your token is stored securely in VS Code SecretStorage. - Open a workspace whose remote is a GitHub repository, check out a branch with
an open PR, and run
Lenzon: Explain this PR.
The explainer plays in a panel beside your editor, themed to match light or dark mode. If analysis is still in progress, you'll see a "still analyzing" state with a check-again action.
Requirements
- VS Code 1.85 or newer.
- A Lenzon account. Free tier works on public repos.
- A workspace with a GitHub remote — either a public repository, or a private repository covered by your Lenzon GitHub App installation.
During the Lenzon beta, the Free tier is all you can eat: bring your own Anthropic key and use it on public repositories at no charge. See lenzon.ai/pricing for current plans.

Settings
lenzon.apiBaseUrl— the Lenzon service URL. Defaults tohttps://www.lenzon.ai; you normally won't change this.
A few additional advanced settings are available for testing specific PRs and enabling developer commands; see the settings descriptions in VS Code for details.
Privacy
Lenzon runs analysis on published repo code. The analysis is used to make an understandable animated script which has privacy keys attatched and is not public by default. We do not share private explainer scripts or analysis with anyone who does not have the appropriate security credentials based on the git repository.
