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

So which one?

Notis aside, Manus covers the most ground: 62% across all 33 capabilities, ahead of Muse (Meta) at 38% and Clark Labs at 36%.

They are not really after the same job, though: Manus for remembering context between conversations, Muse (Meta) for scheduled and event-triggered work and Clark Labs for running long jobs on a machine of its own.

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.

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

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.

Who should pick it

Manus is the one to take when remembering context between conversations is the deciding factor. Walk away if you need to reuse an AI subscription or key you already pay for.

Who should pick it

Pick Clark Labs if running long jobs on a machine of its own is what decides it for you. Walk away if you need it in the other apps you message from.

Our take on how it differs from Notis: Clark splits cloud autonomy and local coding into two separate products with separate sign-ins; Notis is one account and one execution layer across messaging channels and coding agents.

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 Manus, Muse (Meta) or Clark Labs covers the most features?

Manus, at 62% across all 33 capabilities, ahead of Muse (Meta) at 38% and Clark Labs at 36%. That counts documented support, not how well any of it works.

How much do they cost?

Manus: $20–$200/mo (Pro tiers, 4,000–40,000 credits); Team from $20/seat/mo; no free plan currently listed; Muse (Meta): Free with a usage limit; paid subscription for more usage, amounts unpublished.; Clark Labs: Not publicly listed. Different currencies and different units, so there is no honest way to rank these against each other.

Which of them can I try for free?

Muse (Meta) and Clark Labs have a free tier and Manus does not.

Which of them work in WhatsApp?

Muse (Meta) does. Clark Labs does not.

What can none of them do?

How was this comparison put together?

We read whatever each product publishes (103 first-party sources across 4 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 Manus specifically: Manus is optimized for autonomous project runs on its own cloud computer; Notis is optimized for continuous personal context and actions across daily channels and tools.

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.
