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.

4 capabilities in this set.

Part of 4 available through Grocery Savings Calculator.

  2. 02

    Compare discounts

    Use this to find out which of two different sale offers provides the best value per unit. It settles the debate between different brands or package sizes.

  3. 03

    Get savings summary

    This capability provides the exact dollar amount saved and the discount percentage for a single item. It's the quickest way to see the impact of a price drop.

  4. 04

    Validate price integrity

    This capability checks if the price data you provided is logically sound. It ensures your calculations are based on realistic numbers.
