CCortex

Your docs, data and AI agents. One roof.

Cortex replaces Notion, Airtable, Lovable, DocSend, Calendly and Mailchimp with one workspace your team and its agents share.

Release notes

Calendar sync is now two-way. Events created in Cortex show up in Google and Outlook in under a second, and changes made there flow back.

We replaced 5-minute polling with push notifications from each provider and rewrote conflict handling.

How it works. Ask about your data, describe the job once, and an agent does it every morning.

Agents are code you approve once. The model writes the script, you read it, and every run after that is the same steps at near zero cost.

Say what you want done. The builder sets up the databases, booking pages, agents and skills the job needs, then asks you to approve the plan.

What should this project do?

Machines that turn themselves off. A machine starts when an agent needs it and stops when the run ends, so you never pay for idle time.

Questions. Answered plainly.

What does it cost?+

Collaborators are free, whether you are ten people or five hundred. AI is pay as you go. Connect your own keys and you pay us nothing for the AI.

Can we use the AI plan we already pay for?+

Yes. Paste an Anthropic, OpenAI, Google or xAI key and every chat and agent runs on it. A key you connect stays yours: only you and your agents can spend it unless you share it with the workspace.

What stops an agent from making things up?+

Agents are code. The AI writes the script once, you read and approve it, and every run after that repeats the same steps. The model is only called where a step needs judgement.

Do we need a developer?+

No. If you can explain the job to a new hire, you can explain it to the chat. It writes the code, and you never have to open it.

Who can see what?+

You decide per item. A doc, a table, an agent or a whole project can stay private, go to named people, or go to the whole workspace.

What if the tool we need is not listed?+

There is no list. If the service has an API, name it in the chat and the agent calls it through a stored credential.

How fast can we move our data in?+

Same day. Import CSV exports from Notion, Airtable or a spreadsheet and the columns come in typed.

Move the team in this week. Free, with unlimited collaborators.
