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.

Free–$39 per seat/month (Pro $10, Business $19, Enterprise $39, all billed annually; Pro $18 and Business $29 monthly) · fireflies.ai

Who should pick it

Fireflies.ai is the one to take when keeping the product and your data under your own control is the deciding factor. Walk away if you need to reuse an AI subscription or key you already pay for.

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 Tana is built around. Walk away if you need it in the other apps you message from.

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

Pick Otter.ai if rolling a shared assistant out to a team is what decides it for you. Walk away if you need deep integration with the apps you run on.

Our take on how it differs from Notis: Otter is built to capture what was said in meetings and make it searchable afterward; Notis is built to act on what you ask it, across messaging channels (WhatsApp, iMessage, Telegram, Slack, email, voice) and connected tools, with no meeting-capture product at its core.

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 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.
