Muse (Meta) vs Tana

The same 33-row checklist and the same rules. Every cell shows vetted official evidence or “Not checked.”

Visit Muse (Meta) Visit Tana Muse (Meta) alternatives Tana alternatives

So which one?

Notis aside, Tana has the highest checked-evidence score: 47% across 32 vetted rows; 1 row is not checked yet. Muse (Meta): 38% across 33 vetted rows (all 33).

They are not really after the same job, though: Tana for rolling a shared assistant out to a team and Muse (Meta) for remembering context between conversations.

Nothing here publishes anything on Bring your own API key and Run it on your own server.

Only Notis publishes anything on iMessage, Telegram, Email and 4 more rows, and only Tana on Joins and records your meetings, and only Muse (Meta) on Its own iPhone or Android app.

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.

Who should pick it

Tana is the one to take when rolling a shared assistant out to a team is the deciding factor. Walk away if you need a computer it can actually run work on.

Our take on how it differs from Notis: Tana is a native video-call platform: its AI agents join and act during the meeting itself and build a shared context graph across every call. Notis has no meeting platform of its own -- it is a channel-first assistant reached on WhatsApp, iMessage, Telegram, Slack, email and voice.

Who should pick it

Worth it for remembering context between conversations: that is what Muse (Meta) is built around. Walk away if you need to reuse an AI subscription or key you already pay for.

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

Where none of them wins

Nothing on this page publishes anything on Bring your own API key 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 Tana or Muse (Meta) scores highest in the evidence checked so far?

Tana, with 47% across 32 vetted rows; 1 row is not checked yet. Muse (Meta): 38% across 33 vetted rows (all 33). Unknown rows stay out of the score, so treat this as an evidence status, not a complete market verdict.

How much do they cost?

Tana: Free–$80/mo early-bird (Pro $20, Max $80; regular $30/$120), Business custom; Muse (Meta): Free with a usage limit; paid subscription for more usage, amounts unpublished.. Different currencies and different units, so there is no honest way to rank these against each other.

How was this comparison put together?

We read whatever each product publishes (67 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 Tana specifically: Tana is a native video-call platform: its AI agents join and act during the meeting itself and build a shared context graph across every call. Notis has no meeting platform of its own -- it is a channel-first assistant reached on WhatsApp, iMessage, Telegram, Slack, email and voice.

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.
