AI is powerful.
But can you trust it?

Most AI tools are black boxes. They take action without asking, spend without limits, and offer no proof of what happened. You deserve better.

What did it do?Most AI tools can’t tell you what actions they took or why.
What did it cost?Without per-action tracking, AI spend is invisible until the invoice arrives.
Can you prove it?No audit trail means no accountability — for your team or your auditors.
Two halves of one system

Every action logged. Every cost tracked. Every decision auditable. Control Center gives you full visibility into what your AI is doing — and proof it stayed within bounds.

  • Real-time activity feed with action logging
  • Spending dashboards and budget controls
  • Approval workflows for high-stakes actions
  • Operator mode configuration

3 steps

How it works

01

Tell Sidekick what you need

Chat naturally or set up objectives. “Keep my inbox under 20 unreads” or “Triage support tickets by priority.”

02

Sidekick executes within bounds

It works within operator-defined guardrails — never spending more, never overstepping scope, always asking when unsure.

03

You see proof of every action

Every email sent, every meeting booked, every dollar spent — logged, auditable, and provable in Control Center.

Your rules, its rails

Three operator modes

Dial autonomy up or down per workspace. Sidekick always respects the mode you set.

Supervised

Sidekick plans and proposes. You approve every action before it executes.

Guided

Sidekick handles routine tasks. Flags anything outside normal bounds for your review.

Autonomous

Full autonomy within budget and scope guardrails. Proof logged for every action.

Built on trust

The five pillars of governed AI

Guardrails

Operator-defined scope, spending limits, and action constraints. Sidekick can never exceed what you allow.

Transparency

Every tool call logged in real-time with action type, detail, and timestamp. Always accessible in Control Center.

Cost Control

Per-action cost tracking, budget caps, and spending alerts. Know exactly what AI costs you.

Approvals

High-stakes actions require human sign-off. Configure approval thresholds per workspace.

Proof

Structured execution receipts for every action. See what happened, when, and what it cost — for your records or your auditors.

Integrations

Works with everything you use

Connect your tools via MCP. Sidekick speaks the protocols your stack already uses.

Built for operators and developers

Non-technical teams can start with hosted Sidekick immediately. Technical teams can connect governed runtimes through the control-plane SDK without giving up the same trust model.

Start with Sidekick

Use managed inference, connect your tools, and let your team work through approvals, budgets, and proof trails from the hosted product.

Connect a governed runtime

Enroll your own runtime through the control-plane SDK, sync heartbeat, events, evidence, and telemetry, and keep LumenFlow Cloud as the governance authority.
