Compare · Kintari vs Claude Cowork

Agent in a cloud sandbox or in the house.

Claude Cowork is Anthropic\'s agentic layer inside Claude Desktop: you grant folder access, Claude works on it. Useful — but inference still happens in the cloud. Kintari inverts that: the same agentic workflow, but in the encrypted vault, with model choice per task. Your data is yours.

Chapter I · What Cowork is built for

Autonomy in a curated sandbox.

Cowork is a well-thought-through agentic product: explicit folder grants, clear read/write permissions, multi-step autonomous tasks, scheduled routines. Anthropic has taken its time and built a UX that doesn\'t leave the sandboxing question to the user.

Anyone looking to automate routine workflows — recurring research, table analyses, small operations chores — gets a polished tool with Cowork without needing to touch the terminal. Connectors to Slack, Google Workspace, Microsoft 365, and apps like QuickBooks, HubSpot, or DocuSign are available (Cowork plus "Claude for Small Business").

What Cowork doesn\'t solve: whether your files are allowed in the cloud at all. The agent operates on the local folder, but inference and tool decisions still happen on Anthropic\'s servers.

When Cowork
  • — Recurring, non-confidential office workflows.
  • — Cross-app orchestration (Slack, Google, Microsoft).
  • — Cloud processing is fine.
  • — You want Opus quality without model setup.
  • — A subscription is acceptable.
Chapter II · Where Kintari takes a different path

Three axes, shifted.

I.

Inference can stay at home too

In Cowork, the model unavoidably runs in the cloud — otherwise it cannot read your files at all. In Kintari, it\'s a choice per task. Pick a local model and the agent sees your content, the box at home computes the answer, nothing leaves the house.

For professions under confidentiality obligation, that is often the only viable path. Cowork has a clean sandbox architecture, but the model still sees the content — just in cloud memory rather than on disk.

II.

Vault rather than shared folder

Cowork operates on a regular folder of your choosing — fair enough, but every file inside is open to the agent. Kintari has the encrypted workspace as the central data home: knowledge index, configuration, audit log live in an encrypted file. The agent sees what the workspace has indexed — not arbitrary files on disk.

Practical difference: a stolen laptop reveals the contents of the Cowork sandbox folder. With Kintari, it reveals nothing as long as the vault passphrase isn\'t with it.

III.

Multiple agents in the same room

Cowork is Anthropic\'s agent — it does what it does excellently, but it is one agent. Kintari is the hub: the built-in Kintari agent plus bridges to Claude Code, Gemini CLI, OpenCode, Aider, and more. One session, one approval queue — regardless of which agent is doing the work.

For research use the built-in agent, for code refactors Claude Code, for GCP topics the Gemini CLI — and all of them share the same workspace. In Cowork you are locked into Anthropic\'s single agent.

Chapter IV · Where Cowork wins

What we don\'t promise.

Cowork runs on the strongest available model (Claude Opus 4.7) and offers a curated connector suite that fits Anthropic\'s target audience — office/operations/finance workflows in cloud-OK organisations — very precisely. If you belong there, Cowork is a better fit than Kintari.

The polished UX and the ability to start agentic tasks without configuring local models are real strengths we don\'t reproduce 1:1.

Kintari is the right choice when your content may not leave the machine — or when you want the same agentic working style, but with real model choice and an encrypted workspace as home.

Questions we hear

FAQ — Cowork and Kintari.

What exactly is Claude Cowork?
Cowork has been Anthropic's agentic layer inside Claude Desktop since early 2026. You give Claude a folder and a goal; the agent reads and writes files in that sandbox in multiple steps. Inference and tool calls still happen on Anthropic's servers — the local folder is just the read/write target, not the place where the work is computed.
Can Kintari also act on files autonomously?
Yes. The built-in Kintari agent can read, change, and create files in the workspace — all behind explicit approvals. Tool calls are inspectable and reversible, and everything is written to an audit log on disk. Unlike Cowork, inference does not necessarily happen in a cloud; you choose the model per task.
Cowork has connectors for Slack, QuickBooks, HubSpot — does Kintari?
Differently solved. Via its MCP layer and via Composio, Kintari binds in more than 1,500 third-party applications, including Slack, Notion, Google Workspace, Jira, and many more. The advantage: the same connection works with any model of your choice, not just Anthropic's.
Which agent is "smarter"?
For multi-step agentic work, the answer depends heavily on the model. Cowork runs on Claude Opus 4.7, one of the strongest reasoning models available — hard to beat on complex autonomous tasks. Kintari can call that same model if you want. Pick a local open-source model and you trade a bit of reasoning depth for data sovereignty.
Why not just use Cowork?
As long as your content is non-sensitive — go ahead. As soon as client data, patient information, financial or HR data is involved, cloud inference on a shared sandbox is no longer a viable route. Cowork sees every file in the sandbox folder — Anthropic processes them remotely. Kintari keeps the agent local when you need it to.
What about scheduled tasks?
Cowork ships time-scheduled routines (daily, weekly, monthly) as a product feature. Kintari has the same mechanism via its Routines system: defined skills that an agent runs on schedule — say, a Morning Workspace Summary or an inbox-triage run. Functionally the same concept, locally configured in both worlds.
Getting started

Agent yes — cloud optional.

If the Cowork idea resonates but the cloud requirement is in the way, a 30-minute call usually clarifies whether Kintari hits the architecture you need.
