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: reaching it from the apps you already message in

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.

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

What it can do: Creates and edits documents, Save your own reusable instructions, Browses the web for you, Posts to social media for you and Joins and records your meetings
Bring your own AI: Runs on your own ChatGPT plan, Bring your own API key, Works inside your own coding agent and You choose which model runs your work
Where you can use it: Slack, Voice messages, Web or desktop app and Its own iPhone or Android app

Who should pick it

ChatGPT is the one to take when running on the AI subscription you already pay for 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: A broad destination assistant with first-party models and agentic Chat, Work, and Codex surfaces, rather than a channel-first cross-provider execution layer.

Who should pick it

Worth it for remembering context between conversations — that is what Claude 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: Claude is the underlying general intelligence and coding environment; Notis adds persistent personal routing, messaging channels, and an execution layer spanning providers.

What this table does not tell you

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 — 108 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 ChatGPT specifically: A broad destination assistant with first-party models and agentic Chat, Work, and Codex surfaces, rather than a channel-first cross-provider execution layer.

How we checked all this

We read every product on this page against whatever it publishes — docs and pricing pages where there are any, the homepage where that is all there is — 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.
