Demo with a made-up project. The real panel runs inside Claude Code.

Seven kinds of asks, one glance

  • DECIDE

    A judgment call, with each option's pros and risks and Claude's pick starred.

  • PICK

    Choose one, or several, from a short list.

  • TELL ME

    Something only you know. Type it, or say it.

  • SIGN IN

    One button puts the login command in your prompt, or opens the sign-in page.

  • API KEY

    Opens the exact dashboard page and copies the variable name. The key goes in your .env file, never in the panel.

  • REVIEW

    A page, a local app or a preview, with the link front and center, so you never ask for it again.

  • DO THIS

    A step only you can take, like DNS or a store console, with the right page to open.

Built for coming back

  • Looks ahead.

    Reads your first request, the whole chat and the project itself (open TODOs, unset environment variables, what's coming next) to ask now what would block Claude later.

  • Works alongside Claude.

    It keeps looking while Claude builds. Answer mid-build and Claude picks it up at its next step, with no waiting for the turn to end.

  • Review links, automatically.

    When Claude writes an HTML file, starts a dev server or publishes a preview, a review card appears with the link. No more asking where it is.

  • Copy anything.

    Every link in a card is clickable, with a copy button beside it. ⧉ copy puts the whole card on your clipboard, options and all.

  • Fits your screen.

    Shows 1, 2, 3, 6, 10 or 20 cards, or fills the panel and stops at the bottom. Clear one and the next slides in.

  • Type or talk.

    Every card has a field. Press Enter and it goes to Claude right away. ◖ speak puts the question in your prompt for dictation.

  • Never asks for secrets.

    No passwords, codes or key values. It reads env variable names, never their values, and holds back anything you type that looks like a key.

Questions

Does it cost anything to run?

The mod is free. Each look-ahead is one extra model call over your conversation, which is mostly cached, so it's cheap. Set it to look only when you press ↻ if you'd rather.

Can it see my keys or passwords?

It never asks for them. It checks which environment variables are missing by name only, and it won't send anything you type that looks like a key.

Does it slow Claude down?

No. It runs beside Claude and never blocks a tool call. Answers you give mid-build reach Claude at its next step.

Where does it work?

In the Claude Code terminal (fullscreen docks it on the right; otherwise /flow opens it) and in the Claude desktop app.

Is it open source?

Yes, MIT licensed. The source is on GitHub.
