Who should pick it

Fireflies.ai is the one to take when rolling a shared assistant out to a team is the deciding factor. Walk away if you need deep integration with the apps you run on.

Our take on how it differs from Notis: Fireflies starts from recorded conversations and pushes them into your CRM, Slack and inbox; Notis starts from the message you send it and reaches a much wider tool layer.

Who should pick it

Worth it for remembering context between conversations: that is what Notion AI is built around. Walk away if you need deep integration with the apps you run on.

Our take on how it differs from Notis: Notion AI and its Custom Agents/Workers only run inside the Notion workspace and its connected apps, with no consumer messaging channel (WhatsApp, iMessage, Telegram, SMS) into the assistant; Notis reaches users directly on the channels they already use and executes across model providers without a workspace migration.

Where none of them wins

Nothing on this page publishes anything on Bring your own API key. 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 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.
