So which one?

Notis aside, The Librarian covers the most ground: 47% across all 33 capabilities, ahead of Rene at 41% and Zapia at 29%.

They are not really after the same job, though: The Librarian for remembering context between conversations, Rene for scheduled and event-triggered work and Zapia for rolling a shared assistant out to a team.

Cheapest way in is a tie: Notis, The Librarian, Rene and Zapia all start at $0, and only The Librarian, Rene and Zapia have a free plan that does the product's main job.

Nothing here publishes anything on Bring your own API key, Joins and records your meetings and Open source.

Only Notis publishes anything on Runs on your own Claude plan, Runs on your own ChatGPT plan, Works inside your own coding agent and 4 more rows.

Where none of them wins

Nothing on this page publishes anything on Bring your own API key, Joins and records your meetings, 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 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.
