Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Yarn Length Calculator.

  1. 01

    Calculate single segment usage

    This capability calculates the yarn needed for one specific part of a project. It uses your dimensions and gauge to find the exact length required.

  2. 02

    Get yarn weight catalog

    This capability provides a list of standard yarn weight categories. Your agent uses this to ensure calculations match the specific weight of your yarn.

  3. 03

    Calculate multi color project summary

    This capability aggregates multiple color segments into one report. It's useful for projects that require different amounts of various colors.
