Put AI agents to work in private workspaces.

Because useful agents need a full working computer.

A normal SaaS request is short-lived: authenticate, read and write a database, return a response. The application stays shared, and most customer state lives as records.

A durable agent has to do real work. It reads and writes files, runs tools, may execute code, produces artifacts, uses scoped credentials, and resumes across sessions. That work needs an isolated private computer, not just a stateless chat endpoint.

A karta is a durable private computer running your agent.

We call each agent instance a "karta" - Sanskrit for "the doer" - the one who acts.

The agent defines the persona and capabilities. A karta is the persistent computer that runs that agent for a particular relationship, role, or system.

For personal agents, the karta follows the user. When a user starts the first session with an agent, Karta creates that user-agent computer. Every future interaction between that user and that agent returns to the same karta.

For shared agents, the karta represents the role. A virtual employee can be one persistent karta with its own files, sessions, memory, and working style. Multiple humans can interact with it because they are collaborating with the same durable agent computer.

The workspace persists. Files, drafts, decisions, research, knowledge graphs, and half-finished work accumulate over time, so the agent resumes the process instead of starting from a blank prompt.

The identity is scoped. A visitor can start anonymously and keep the same workspace after verification. Access can be anonymous, soft-verified, or fully verified.

The relationship stays yours. You own the agent definition, the user relationship, and the work product. Karta runs the substrate: private agent computers, durable workspaces, isolation, metering, spend controls, and access surfaces.

Bring a harness. Karta turns it into running kartas.

Karta is a managed agent harness platform, so it does not force a new authoring workflow. Start in the browser, upload a folder, push to Karta, or wire it into CI. Each path builds an immutable release that can run as one private computer or a fleet of them.

1. Build it in the console. Start from a template and ship a simple agent without leaving the browser.
2. Upload a folder. Point Karta at a local harness project.
3. Push to Karta. git push karta main to its hosted git remote.
4. Wire up CI/CD. Connect GitHub so every push deploys.

One runtime for products, software, and fleets.

Use Karta when the agent needs continuity: its own files, sessions, credentials, artifacts, and memory of the work. That can be a product, the next interface to software you already sell, an internal teammate, a system representative, or a coordinated fleet.

The operational layer has to be part of the runtime.

Durable agents touch files, tools, credentials, and business process. Karta packages the controls enterprises expect into the runtime: isolation, durable workspaces, metering, billing, identity, deployment, audit, and governance.

Each session runs in its own secure, isolated microVM - the boundary for untrusted agent code. Streaming-first, with prepaid billing and per-instance spend controls built in.
