Why si-world

Principles you can inspect.

Every claim below maps to how the product actually works.

Local-first, not cloud-first

The core runs offline; data stays on your machine. The dashboard binds to 127.0.0.1 by default.

Plain files over lock-in

Tasks and chats live in .atm_agent/ — readable, Git-friendly and easy to back up.

Open standards

MCP keeps AI collaboration portable across clients, instead of locking you to one vendor.

Traceable by default

Every task keeps its conversation, summary and report — exportable to Markdown.

One-time ownership

Lifetime license per device, with up to 5 delegated devices on the same email. No subscription.

Small, focused tools

We build few products and support them for the long term — not a portfolio of experiments.

How it works

Agent Task Manager in three steps.

01

Install the extension

Install Agent Task Manager in VS Code. The 1-month free trial starts automatically.

02

Work in plain language

Describe the outcome; your AI assistant creates tasks and works through them.

03

Keep the trail

Conversations are archived, summarized and reportable — entirely offline.

Internet is needed only for the purchase & licensing flow; license verification happens locally.
