COGNITION API

Give your model a mind.

Most AI starts every query from scratch. Adapter is a cognition layer that sits alongside your model — reading, connecting, and comprehending your data continuously, so by the time your agent asks, the answer is already there.

PROBLEM

Inference is not cognition

LLMs are powerful, but on their own, they don't know your world: your data, your people, your history and why it all came to be. So they struggle to understand the nuance about the things that matter most to you.

Limited memory

Every session starts from zero. It doesn't remember what you told it yesterday — or what "yesterday" even means.

Limited context

It can't connect an issue on a Slack thread to a Linear ticket to a PR that's stuck in review because someone's on vacation.

Limited understanding

It can find the document, but it can't tell you who owns the decision, what it depends on, or whether anyone still agrees.

You shouldn’t have to become a plumber to build smart AI

Today, giving your AI real context means stitching together a stack of tools that are expensive to build, painful to maintain, and still don’t actually understand your data.

SOLUTION

Go from stateless AI


to true cognition.

Go from stateless AI to true cognition.

Adapter reads, structures, and connects your data continuously, so by the time you need an answer, the understanding is already there.

Plug in any data source. Adapter maintains understanding, continuously, in real-time.

Ask hard questions and get answers grounded in your data.

Ground every answer in evidence

Every response from Adapter cites the documents, conversations, and decisions behind it, so you can trace any answer back to its source.

Surface hidden connections

Adapter automatically connects entities across your data, so you can trace what's blocking what: from a pull request, to the Linear ticket waiting on it, to the Slack conversation holding it up.

Know the moment something changes

Describe what to watch in plain language and point Adapter at a webhook. Adapter watches your data continuously and pings you the moment something you care about shifts.

Stay ahead of what’s next

Adapter sees what's coming and serves up the full context around it. Use those signals to trigger downstream workflows, like meeting prep, account briefings, or pre-call research.

Every new piece of data is interpreted against everything Adapter already knows. After six months, the answers to your hardest questions are sharper than they were on day one.

Your data already has the answers.


Adapter unlocks them.

HOW ADAPTER WORKS

From raw data to verifiable understanding, with one API.

Connect your data sources and Adapter builds a living knowledge graph — extracting entities, relationships identities, and compounding context with every new piece of evidence.

WHAT YOU CAN BUILD

What Adapter unlocks.

Build new AI products, make existing ones smarter, or get straight answers from the data you already have.

Ship agents and AI apps with cognition

Building a second brain or agent? Adapter is the memory and context harness underneath, so you can focus on the product rather than the plumbing.

PLATFORM & SECURITY

Built by graph computing and privacy pioneers.

Our team has spent decades building the algorithms that make large-scale knowledge graphs work. Adapter is built so the data serves you, stays in your control, and is never used to train models.

Portrait of David Bader, Ph.D.

David A. Bader, Ph.D.

Co-Founder & Chief Knowledge Officer

"I've spent my career building graphs for the world's most demanding systems — national security, commercial networks, and high-assurance infrastructure. At that scale, data is only as valuable as your ability to reason over it in real-time. That's what we brought to Adapter."

The full Adapter loop is patented

From data ingestion to contextual understanding to action —covered by U.S. Patent No. 12,511,553, granted December 2025.

Secure at every step

All data is isolated and encrypted at rest. Workspaces exist in isolated runtimes via a robust container model.

FAQs

What is Adapter?

Adapter is a Cognition API. It continuously processes the data resulting from your activities across life from personal to professional while building persistent and structured understanding your agent can act on. When you prompt your model, it does inference. Adapter handles what happens before, so that by the time your agent asks a question, the understanding is already there.
