Manus vs Viktor vs Zo Computer

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

So which one?

Notis aside, Zo Computer covers the most ground: 73% across all 33 capabilities, ahead of Manus at 62% and Viktor at 53%.

They are not really after the same job, though: Zo Computer for running on the AI subscription you already pay for, Manus for remembering context between conversations and Viktor for keeping the product and your data under your own control.

Cheapest way in is Notis at Free–$149/mo, though its free plan only does part of the job.

Nothing here publishes anything on Open source and Run it on your own server.

Only Notis publishes anything on Connects to MCP servers on your computer, and only Zo Computer on Bring your own API key, and only Manus 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.

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.

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 support for your own AI plan: no published support for Bring your own API key.

Who should pick it

Zo Computer is the one to take when running on the AI subscription you already pay for is the deciding factor. Walk away if you need open source, self-hosting or a named certification.

Our take on how it differs from Notis: Zo is especially strong as a programmable cloud computer; Notis is more turnkey as an assistant and subscription-aware agent router.

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.

How was this comparison put together?

We read whatever each product publishes (146 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?

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.
