AudioPen vs Iris vs Otter.ai

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

So which one?

Notis aside, Otter.ai covers the most ground: 41% across all 33 capabilities, ahead of AudioPen at 18% and Iris at 15%.

They are not really after the same job, though: Otter.ai for rolling a shared assistant out to a team, AudioPen for reaching it from the apps you already message in and Iris for remembering context between conversations.

Nothing here publishes anything on Bring your own API key, Open source and Run it on your own server.

Only Notis publishes anything on WhatsApp, iMessage, Telegram and 10 more rows, and only Otter.ai on Joins and records your meetings.

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–$30/user/month (Business monthly; $19.99 annually). Pro $16.99/user/month or $8.33 annually. Enterprise custom. · otter.ai

Who should pick it

Otter.ai is the one to take when rolling a shared assistant out to a team 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: 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.

Who should pick it

Worth it for reaching it from the apps you already message in: that is what AudioPen is built around. Walk away if you need it to remember across conversations.

Where none of them wins

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

Questions people ask

Which of Otter.ai, AudioPen or Iris covers the most features?

Otter.ai, at 41% across all 33 capabilities, ahead of AudioPen at 18% and Iris at 15%. That counts documented support, not how well any of it works.

How was this comparison put together?

We read whatever each product publishes (86 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 Otter.ai specifically: 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.

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.
