Now in private beta

Your team's shared brain

The collaboration platform where AI handles execution and humans make the decisions that matter. Not another chat tool. A shared memory.

The problem

Your team's knowledge is scattered across Slack threads, Notion docs, Jira tickets, and email chains. Decisions vanish. Context gets lost. Every new team member starts from zero. AI made this worse — more output, same broken channels.

Not messages. Objects.

Cortex replaces unstructured noise with five structured primitives.

Decision

A resolved choice with context, rationale, and alternatives considered. The atomic unit of team progress. Never lost, always searchable.

Question

Something needing group judgment. Has options, a deadline, and urgency. When resolved, it becomes a Decision automatically.

Insight

Something learned that others should know. Proactively surfaced to affected teammates by the attention engine.

Memo

Longer-form thinking — design docs, RFCs, proposals. AI helps draft and extract structured objects from prose.

Signal

Freeform chat for when you just need to talk. Always available. AI extracts structure from conversations automatically.

How Cortex works

1

AI agents write to the shared brain

Your team's AI agents publish decisions, insights, and progress automatically. GitHub PRs become Decisions with context about why, not just what.

2

Attention routing surfaces what matters

Instead of broadcasting everything to everyone, Cortex routes the right knowledge to the right person at the right time. Based on semantic similarity, your current work, and urgency.

3

Humans make the calls that matter

Questions queue up for group judgment with full context pre-loaded. Vote, discuss, resolve — and the Decision is permanent. No more "wait, when did we decide that?"

4

Nothing is ever lost

Every decision, its rationale, every insight, every context shift — searchable forever. New team members inherit the full institutional memory on day one.

A day with Cortex vs. without

Same team, same work. Different operating system.

Without Cortex
Morning catch-upScroll through 120 Slack messages, 14 threads, 3 Notion pages. Miss the one that matters.
Finding a past decision"I think we decided that in a Slack thread? Or was it a Google Doc? Ask Jake, he might remember."
Code review contextRead the diff. Guess why. Check Jira. Check Slack. Still guessing.
Resolving a disagreementDebate in Slack for 3 days. Decision happens in a call nobody documents. Revisited next quarter.
Onboarding someone new"Read these 40 docs. Ask Sarah for context. It'll take a few weeks to get up to speed."
End of weekStandup: "I worked on stuff." Nobody knows the full picture. Progress is a feeling, not a fact.
With Cortex
Morning catch-upOpen daily synthesis. 30-second scan: what moved, what's blocked, what needs you.
Finding a past decisionSearch "database migration." Decision with full rationale, alternatives considered, and linked context. 5 seconds.
Code review contextPR auto-summarized with why it was built, linked to the Decision that prompted it.
Resolving a disagreementQuestion created with options. Team votes with context. Resolves into a permanent Decision with rationale.
Onboarding someone newFull institutional memory from day one. Every decision, every rationale, every insight — searchable and linked.
End of weekWeekly synthesis shows exactly what happened. Encounter log captures what the team learned, not just what it shipped.

Built on principles

Shared memory, not a chat channel

The platform is a living knowledge base with an attention layer, not another place for messages to scroll past.

Never atrophy human judgment

AI surfaces information for humans to decide. It never decides for you. Your team's judgment gets sharper, not lazier.

Make each encounter count more

Weekly reflections, collision detection, daily synthesis — designed so every interaction deepens shared understanding.
