Works with Meta Muse
Muse does it.
Judd makes sure it should.
Judd is your buyer’s advocate. Your Muse agent checks with Judd before it books travel or a restaurant, buys something or changes a subscription. Judd works only for you, never for a seller: it checks the price, the reviews, the seller and the terms, swaps in a better option when there is one, and only asks you when it matters.
Free during the open beta. Judd never sees your card, passwords or accounts. Judd recommends; you decide.
Why add Judd
When every action asks for approval, you stop reading and start tapping yes.
Muse checks in before anything sensitive, and you should keep that on. But an agent that asks about everything trains you to approve everything. Judd sits in front of those asks. It holds every option against your rules first, so what reaches you is worth a real look.
Muse on its own
- Proposes the option it found, and you approve or decline.
- You do the checking: the return policy, the plan length, whether you already pay for something like it.
- Every purchase looks the same in your approvals.
Muse with Judd
- Muse asks Judd first. Judd answers in seconds with a verdict and a one-line reason.
- Judd applies your limits and rules every time, and picks the better option when the agent didn’t.
- Only real judgment calls come to you, with Judd’s reason attached.
What Judd checks
The three places agents spend your money.
Travel
Before Muse books a flight, hotel or car.
- Refundable or not, based on how firm your plans are
- Your times, airlines and hotel brands
- Fees paid later at the property
- Dates you protect and trips that overlap
Purchases
Before Muse buys anything over $50.
- The better seller for the same item
- Return policy, condition and delivery date
- The same thing ordered twice in a month
- Your spending limit
Subscriptions
Before Muse starts, renews, changes or cancels one.
- Monthly or annual, using real expected cost
- Renewals for things you don’t use
- A new service that does the same job as one you already pay for
- Free trials that are about to bill you
Example verdicts are Judd’s actual output for sample requests, using the default preferences. You can change every limit.
Seven answers
Judd always answers with one of seven verdicts, and the reason.
Go ahead with what Muse proposed.
YESDo this other option the agent found instead.
INSTEADNone of these fit, or the evidence is missing. Here’s what to look for.
FIND_BETTERThe price or terms are open. Ask for better before buying.
NEGOTIATEA sale or a new model is coming, and you don’t need it yet.
WAITA real judgment call. You decide, with Judd’s reason.
ASK_YOUStop, and tell you why.
NOEvery decision is saved to your Judd dashboard with the options, the rules applied and a concrete “this would be wrong if…” condition, so you can check Judd’s calls against what actually happened.

Paste this into Muse
Build a custom integration to Judd. The MCP server is at https://judd.flowinfo.co/mcp over streamable HTTP and needs my API key as a Bearer token in the Authorization header. Then remember this: before you book any travel or restaurant table, buy anything that costs $50 or more, or start, renew, change or cancel a subscription for me, check with Judd first and follow its answer. If Judd asks me and I answer on my Judd dashboard, check with Judd again before acting. Afterwards, tell Judd what you did. When Judd's answer includes his mascot, show it as a small inline icon right before his name, about 24 pixels tall (the height of a line of text), never as a big picture or a link card.
-
Give Muse your key, safely
When Muse asks for the API key, paste it into its secure credential prompt.
Never paste your Judd key into the chat itself. Anyone with your key can use Judd as you.
-
Try it
- “Find me noise-cancelling headphones under $300 and check with Judd before buying.”
- “Go through my subscriptions and ask Judd which ones to cancel.”
- “Book a quiet dinner for 4 Friday at 7 near the office and check with Judd first.”
- “Plan my Chicago trip Oct 13 to 16 and check with Judd before booking.”
Each call shows up on your Judd dashboard, where you can set your limits and rules. Try a few before you rely on it, and confirm Muse checks with Judd every time.
Questions
Good to know.
Does Judd touch my money?
No. Judd never sees your card, passwords or accounts. Muse still does the buying and booking, with Muse’s own approvals. Judd only sees the options Muse sends it and answers with a verdict.
Who is responsible for what my agent does?
You are. Judd only makes recommendations, based on the information your agent sends it, and it can be wrong. You and your agent make every final decision about what to book, buy, renew or cancel. Flow Information Systems is not responsible for those decisions or their results. See the Terms.
Should I turn off Muse’s purchase approvals?
No, keep them on. Judd makes sure what Muse proposes is the right call, and Muse’s approval still guards the payment.
Is it free?
Yes, Judd is free during the open beta.
How does Judd decide?
First your rules: spending limits, return and refund preferences, preferred and avoided sellers and airlines, dates you protect. Then expected-cost math, for example how likely you are to cancel a subscription in the next year. When Judd approves something, your agent checks it against your standing instructions and anything you said in the conversation. That check can only make a decision more careful, never less. Judd itself makes no AI calls.
Does Judd only work with Muse?
No. Judd works with any agent that supports MCP, including Claude, ChatGPT, OpenClaw and Poke.
Is Judd made by Meta?
No. Judd is made by Flow Information Systems™ and is not affiliated with or endorsed by Meta.
What does Judd keep?
Your preferences and each decision, so you can review them on your dashboard. See the Privacy Policy for details.
