Muse vs Instinct: Two AI Assistants, and Only One You Can Actually Use

Muse vs Instinct is the head-to-head everyone in the agentic assistant space is asking about, and the first honest answer is that it is not yet a fair fight. Meta's Muse is live in the US today. Instinct is private access with a waitlist and no published price. Both promise an assistant that acts rather than answers, both connect to your accounts to do it, and neither takes notes on your conversations. Here is what each one actually is, and the one clause in Instinct's terms you should read before connecting your email.

You Cannot Actually Choose Between These Yet

Worth stating before anything else, because a lot of coverage puts them side by side as though you could pick one this afternoon.

Meta says Muse "is rolling out in the US on iOS, Android, and muse.ai, and coming soon to AI glasses". So it exists, today, if you are American.

Instinct's own site says: "Instinct is currently available to a private access group as we're scaling up compute. You can join the waitlist here or ask an existing member to invite you." So for most readers the practical comparison is Muse against nothing.

That has not stopped Instinct attracting serious money. Third-party reporting puts a $250 million Series B at a $2.5 billion valuation behind it, which tells you investors expect it to matter, not that you can use it.

What Each One Claims to Do

Muse. Meta calls it "a secure, private personal AI agent that proactively helps people meet their goals and suggests ideas", and its headline capability is that it can "open a browser, fill out forms, and negotiate on their behalf". It runs inside an isolated environment Meta calls the Muse Secure VM, powered by a model called Muse Spark.

Instinct. Its site describes "a personal assistant that understands what you're working on and what's important to you", and the mechanism is unusual: "It's trained to use a phone and a computer" and "uses its devices in the same way that humans do". You interact by text or phone call rather than through an app.

Instinct's own examples are the more concrete of the two: "following up on threads you've dropped, proactively calling or texting you, arranging a ride to the airport, booking a handyman for your apartment". That is a clear picture of the job. Muse's framing is broader and vaguer, which may simply reflect a bigger company being careful.

Neither of Them Takes Notes

If you arrived from the AI recorder or memory pendant world, this is the section that matters.

Neither product claims to transcribe conversations, produce meeting notes, or give you a readable record of what was said. Muse has memory in the sense of a preference profile: Meta says it "remembers what matters to a person, so it can make suggestions unprompted", and you can tell it to forget things. Instinct ingests information about what you are working on in order to act, not to hand you a document.

That is not a criticism. They are task assistants, and the job of reducing your admin is a real job. But the word memory is doing different work in that sentence than it does when a recorder says it. An agent that remembers you prefer aisle seats is not going to tell you what your manager committed to on Tuesday.

We wrote about Muse on its own terms in What Is Meta's Muse?, and about which tools genuinely produce a record in ADHD Tool That Turns Conversations Into To-Dos.

Audio Is Where They Genuinely Differ

This is the one hard, documentable difference between them, and it runs in a direction that may surprise you.

Instinct explicitly collects audio. Its homepage says it "connects to your applications and devices - email, messaging, screen, audio, location, and more", and its privacy policy states that "The Services may also collect audio and voice data, should you choose to enable these features". So audio is opt-in, but it is a stated capability, alongside your screen and your location.

Meta has published nothing about audio for Muse. Not that it listens, not that it does not. The announcement and the security material simply never mention microphones or recording.

We are reporting that gap as a gap. Silence is not a privacy guarantee, and it is not an accusation either. It may become a live question when Muse reaches AI glasses, which have microphones by design.

Read Instinct's Terms Before You Connect Your Email

If you get waitlist access, this is worth ten minutes of your time, and it is the single most consequential thing in this comparison.

Instinct's terms grant it a "perpetual and irrevocable" licence to "access, use, host, cache, store, reproduce, transmit, display, publish, distribute, and modify" user materials, "including for training its AI models". There is an opt-out for materials outside what Instinct calls the Vault, and you can delete indexed data from the workspace area of the product.

Perpetual and irrevocable is strong language for a consumer product that wants access to your email, your messages and your screen. It may well be boilerplate drafted defensively. It is still a clause you should understand before you connect an account, because the whole value proposition requires handing over a lot.

TechCrunch has also reported that a tester found that after disconnecting Instinct's access, their emails remained stored in plain text for later searches. That is third-party reporting rather than something Instinct publishes, and we flag it as such, but it is the kind of detail worth asking about directly.

Neither company publishes a retention period. Not Meta for Muse, not Instinct.

What They Cost

Neither has a price list you can rely on.

Meta's only published statement is that Muse "is free for most of what people need, with subscription plans for people who want to do more". TechCrunch and Axios have both reported paid tiers at $20 and $100 a month. That reporting is consistent, but it is not a Meta price list and we are not presenting it as one.

Instinct publishes no price at all. Not a figure, not a tier, not a currency. Third-party coverage suggests it is free during the private access period, which is a normal thing to do while scaling compute and tells you nothing about what it will cost later.

So on cost, the honest position is that Muse has a free tier you can try today, and Instinct's pricing is genuinely unknown.

Which One to Try

Try Muse if you are in the US and curious. It is available, Meta says the useful tier costs nothing, and an agent that can drive a browser and fill in forms removes real work. The security thinking Meta has published, particularly around prompt injection, suggests they have taken the hard part seriously.

Join Instinct's waitlist if the phone-and-computer approach appeals, and read the terms properly when access arrives. Its examples are more concrete and its interaction model, texting or calling an assistant, is genuinely different from opening an app.

Do not pick between them on privacy yet. Instinct tells you it can collect audio and grants itself a broad licence. Meta tells you almost nothing about audio at all. One of those is more disclosed, not necessarily more protective.

Where Neither Helps

Both are built to reduce what you have to do. Neither is built to tell you what happened.

If the thing failing in your week is that people tell you things and they disappear, an agent that books your handyman does not touch it. That is a different product category, and no amount of agentic capability substitutes for a record.

Legend One is built for that failure. It is a voice-first AI memory pendant made for people with ADHD, worn at chest height with three microphones and speaker separation, always on with no button. It transcribes speech to text instantly across more than 150 languages, and no audio file is written at any point. Transcription happens on the device and the text is stored locally, then syncs to your phone when back in Bluetooth range. A Halo light shows when it is active. It is $499 USD including the first year of membership, renewing at $499 a year, which is $1,497 over three years, with a 30-day money-back guarantee.

And the corresponding honesty: Legend will not book anything, fill in a form, or chase a thread you dropped. If your problem is admin volume rather than lost information, one of these agents is the right tool and a pendant is not.

The Takeaway

One ships, one does not, and neither is a notebook.

Use Muse if you are American and want to try an agent today at no cost. Wait on Instinct until access opens and the pricing exists, then read the licensing clause before connecting accounts. Assume neither gives you a record, because neither claims to, and the marketing use of the word memory obscures that. Ask both about retention, because neither publishes a period, and with an agent holding your email, messages and screen that is the question that matters most.

FAQ

Is Instinct better than Muse? You cannot meaningfully compare them yet. Muse is rolling out in the US today with a free tier. Instinct is limited to a private access group with a waitlist and publishes no price. Instinct's described jobs are more concrete, but availability decides this for now.

Do Muse or Instinct take notes on your conversations? Neither claims to. Both are task assistants that act on your behalf. Muse has a preference profile it calls memory, which is not a transcript, and Instinct ingests context in order to act rather than to produce a document you read back.

Does Instinct record audio? Its privacy policy states that the services "may also collect audio and voice data, should you choose to enable these features", and its homepage lists audio among the things it connects to. So it is opt-in but explicitly supported. Meta has published nothing about audio for Muse in either direction.

What do Muse and Instinct cost? Meta says Muse is free for most needs with paid plans above that, without publishing figures; outlets have reported $20 and $100 a month tiers. Instinct publishes no price at all.
