coOwn is built for holistic, centaur-mode technology: tools that expand what you can do instead of telling you how to work. BrainMail is the newest way in.

Technology that expands the worker

Prescriptive technology expects the worker to conform to its intended use. Holistic technology expands the worker's agency and makes new things possible.

In centaur mode the human is on top, supported by the machine and helped to do more. In reverse centaur mode the human is in the loop to support the machine, correcting LLM-generated material or running its errands.

Reverse centaur is where the puck is today. We are building for where it is going: business owners who will demand tools that give them centaur powers to grow.

Introducing BrainMail

Premium businesses can activate an email inbox and connect it to a Brain. The inbox knows your meetings, tasks, content library, brainwaves, recent email discussions with the sender, and the programs your business has configured.

Employees and authorized external users simply send an email. BrainMail works on the request and replies, and they can keep collaborating by replying, as they would with a colleague. Ask it to generate a report, share progress, upload to the Brainwave or organize a meeting.

Built-in guardrails

Access control
Built into every BrainMail.
Audit
Built in, so activity can be traced.
Owner approval for external senders
BrainMail waits for the email owner to approve before responding to an external user.
Approvals by email
Approve or decline actions like adding to a Brainwave or creating a meeting, without logging in to coOwn.
I'm one person running 7 projects. I have 10 employees I can't train on the interface. My partners will never learn a complex system.

Steady progress around BrainMail

Meetings
Meetings without the brainwave, calendar invites with full RSVP, custom video backgrounds, and docking so you can keep working.
Chat
UI polish on the new Chat view for businesses and individuals.
Content library
Markdown file support is now in the content library.
Notion connector
Fixed for users running the app from custom domains.
