Never lose track of what your coding agents are building.

BuildGist explains what changed, how it works, and what you should understand after every meaningful agent run.

Get started Free. Sign in with GitHub, then download BuildGist for Mac. Explanations use Claude Code, under your own Claude account.

Works with Claude Code, Cursor and Codex, on your local, uncommitted changes. No commit or push required.

Worth understanding

How 'Sign in with Google' actually works

OpenID Connect (OIDC) authorization code flow

Instead of the app storing passwords, it sends visitors to Google to prove who they are, then Google hands back a signed statement of identity that the app trusts.

Worth a look

Risk

Any signed-in user can delete anyone else's note

Signing in now protects the delete button from strangers, but it doesn't check whether the note is actually yours. Any team member who's signed in can delete anyone's note, not just their own.

One real explanation, from a Claude Code run on a small notice-board app. This is what you read before asking for the next thing.

Your agent writes the code. BuildGist catches you up.

Instead of asking your agent “what did you do?” after every task, BuildGist explains it automatically.

Set up once. Then code as usual.

Sign in with GitHub and download BuildGist for Mac. It connects your Mac and sets up Claude Code, Cursor and Codex once, for every project. Then use them as usual: meaningful runs are explained on your Mac and appear in your Inbox. No commit or push required.

Get started

Read the setup guide

Free during the early public release. BuildGist for Mac needs Apple silicon (M1 or later); Linux and Intel Macs use the command-line setup. Windows is not supported yet. Explanations need Claude Code, signed in on your computer: it writes them under your own Claude account, whichever agent made the run.
