Document your entire .NET codebase in minutes, not months

A Visual Studio extension that uses Roslyn semantic analysis to generate accurate XML doc comments — for a single method, a file, or your whole solution.

How it works

1

Install the extension

Add the Visual Studio 2022 extension from the Marketplace.

2

Get a token

Sign up free for an API token — or upgrade to Pro or Pro Plus and bring your own Anthropic or OpenAI key to bypass our backend entirely.

3

Generate docs

Right-click a member, file, project, or solution and let the AI write the XML docs.

Features

One-click generation

Generate docs from the editor context menu — no copy-pasting into a chat window.

Project & solution scan

Find every undocumented member across a project or the whole solution and fix them in one pass.

Your style, enforced

A .docengine.json file controls tone, remarks, examples, and paramref usage.

BYOK or hosted

On Pro or Pro Plus, use your own Anthropic or OpenAI API key for truly unlimited generations — the extension calls your provider directly and our backend is never touched.

Inserted in place

Comments land directly above the right members in your source files.

Transparent limits

200 members/month free. Up to 10,000/month on Pro Plus. Resets automatically.

FAQ

What does BYOK mean?

Bring Your Own Key. Available on Pro and Pro Plus plans. Paste your own Anthropic or OpenAI API key and the extension calls your provider directly — our backend is bypassed entirely, giving you truly unlimited generations. You pay your provider; we don't touch your quota.

What happens when I hit the free limit?

Generation requests return an "upgrade required" error until the month rolls over. Upgrade to Pro (2,000/month) or Pro Plus (10,000/month) for a higher limit.

What counts as a "member"?

Each method, property, class, or other C# member that gets a doc comment generated counts as one. Re-generating the same member in the same month doesn't count again on the Free plan.

I lost my token. Can I recover it?

No. Tokens are shown exactly once at signup and never stored in a recoverable form. If you lose it, sign up again with a different email.

Which Visual Studio versions are supported?

Visual Studio 2022.
