Muse (Meta) covers 38% of the checked capabilities, while Instinct covers 32%; those figures describe the evidence in our table, not how well either assistant will perform your tasks. Notis covers 80% and adds documented Slack, Telegram and email channels, although its messaging channels require a paid plan.

The catch with each one

Numbered by support score across vetted capability rows, with incomplete evidence shown on every card. Unknown rows never count as a no, and this is not a score against your answers.

1. Notis

Personal AI assistant

Notis is a personal AI assistant you message from WhatsApp, iMessage, Telegram, Slack or email, and reach from your own coding agent through its MCP server.

Notis suits people who want to reach an assistant from their usual messaging apps and from their coding agent. It covers 80% of the checked capabilities, including browsing, persistent memory, reusable instructions and scheduled work. The catch is that the free plan is limited to the coding interface; messaging channels need a paid plan, and we found no standalone mobile app.

Best for: running on the AI subscription you already pay for

Documented strengths

Where you can use it: WhatsApp, iMessage, Telegram, Slack, Email, Voice messages and Web or desktop app

Bring your own AI: Runs on your own Claude plan, Runs on your own ChatGPT plan, Works inside your own coding agent and You choose which model runs your work

The catch

Official evidence records a gap in published guarantees about your data: no published support for Open source and Run it on your own server.

2. Muse (Meta)

Personal AI agent

Meta personal agent for delegated everyday tasks, web actions and ongoing goals.

Muse (Meta) suits people delegating personal tasks and ongoing goals, with WhatsApp access and a dedicated mobile app. Its documented capabilities include a persistent cloud computer, browser actions, memory, scheduled work and reminders, reaching 38% of the checked capabilities. You can use the main agent for free within a usage limit; paid subscription amounts remain unpublished, and the data-training policy requires you to opt out.

Best for: remembering context between conversations

Documented strengths

Where you can use it: WhatsApp, Web or desktop app and Its own iPhone or Android app
Memory: Remembers you between conversations and Reads your existing files and apps
Runs without you: Runs on a schedule or a trigger and Reminds and nudges you

The catch

The checked gap is messaging channels. Nothing published on iMessage, Telegram, Slack, Email, SMS or a phone number and Voice messages.

Who should pick it

Muse (Meta) is the one to take when remembering context between conversations is the deciding factor. Walk away if you need it in the other apps you message from.

Our take on how it differs from Notis: Dedicated persistent cloud computer, WhatsApp access and approval-gated actions.

3. Instinct

Autonomous personal assistant

A personal assistant you text or call, which connects to your applications and devices and acts on your behalf.

Instinct suits people who want an assistant they can message through WhatsApp or iMessage and call for everyday tasks. It browses the web and reads connected applications, while evidence for persistent memory and scheduled work remains partial. Its coverage is 32% of the checked capabilities, with private access and no public price list, so check availability before building your routine around it.

Best for: scheduled and event-triggered work

Documented strengths

Where you can use it: WhatsApp and iMessage
Memory: Reads your existing files and apps
What it can do: Browses the web for you

The catch

The documented gap is a computer it can use. We found no published support for Controls your own computer.

Who should pick it

Worth it for scheduled and event-triggered work: that is what Instinct is built around. Walk away if you need a computer it can actually run work on.

Our take on how it differs from Notis: Instinct is invite-only, runs on its own model and its own phone and computer, and you reach it only by texting or calling a number it assigns - not through WhatsApp, iMessage, Telegram, Slack or email. Notis is generally available, publishes its prices, and meets you across the messaging channels and integrations you already use.

Where none of them wins

Nothing on this page publishes anything on Open source and Run it on your own server. If one of them is the thing you actually need, none of these is your answer.

One more thing, because a table like this can be read for more than it is worth. It counts what each product documents. It says nothing about how reliable any of them is, how fast it replies, how good its writing is, or what it does when an integration breaks on a Friday night. A lower support score can still be the better daily driver. The only way to know is to put a real week of work through both.

A dash means the capability was not documented on the official pages we checked. Not checked means the evidence is still incomplete.

Questions people ask

Which of Muse (Meta) or Instinct scores highest in the evidence checked so far?

Muse (Meta), with 38% across 33 vetted rows (all 33). Instinct: 32% across 25 vetted rows; 8 rows are not checked yet. Unknown rows stay out of the score, so treat this as an evidence status, not a complete market verdict.

How much do they cost?

Muse (Meta) offers free use with a limit and a paid subscription whose amount is unpublished. Instinct has no publicly listed pricing for its private access group, while the Notis range is Free–$149/mo, with paid plans required for messaging channels.

Which of them can I try for free?

Muse (Meta) offers a free tier that performs the main personal-agent job within a usage limit. Notis also offers a free plan, limited to the coding interface, while we could not verify a usable free plan for Instinct.

Which of them work in iMessage?

Instinct does. Muse (Meta) does not.

What can none of them do?

Notis, Muse (Meta) and Instinct have no published open-source release or supported self-hosting option in the evidence we checked. That describes the evidence available when checked, rather than a promise about what these products might offer in future.

How was this comparison put together?

We read whatever each product publishes (76 first-party sources across 3 products) and scored all of them on the same 33 rows. Last checked 21 August 2026. A dash means the capability was not documented on the official pages we checked. Not checked means the evidence is still incomplete.

Where does Notis fit in?

At number 1, scored by the same code on the same 33 rows as everything else. Against Muse (Meta) specifically: Dedicated persistent cloud computer, WhatsApp access and approval-gated actions.

How we checked all this

We read what every product on this page publishes (docs and pricing pages where there are any, the homepage where that is all there is) and checked it against the same 33 buyer-focused rows. A support score uses only rows with an explicit vetted state; every unchecked row remains visible and never becomes a no. Notis chose the questions and is scored by the same rule. Count the links below before you weigh a result; some vendors give us three pages and some give us one. Last checked 21 August 2026. No vendor briefings, no affiliate links, no press releases.

The verdict, the paragraph on each product and the answers to the questions above were drafted by a language model working from the table on this page and nothing else, then checked back against it by a script. Every number, price and capability claim has to match the dataset or the draft is thrown out and you read the written-from-data version instead. The ranking, the table, the scores and the sources are computed, never written.
