PowerGrabber: LLM Certainty.

PowerGrabber is a monitoring application for macOS, Windows, and Linux. PowerGrabber captures LLM traffic in two ways: via browser extension for browser-based AI usage such as ChatGPT, Gemini, and Claude, and directly at the API for AI applications such as Claude Code — logging everything as structured, compliance-ready data.

PowerGrabber is launching soon.

Certainty

Certainty looks like this.

Complete Visibility

You know which AI tools are in use. Every AI service accessed through the browser or at the API level is captured, identified, and logged. ChatGPT, Claude, Gemini, Claude Code, and every other LLM interaction — visible, attributed, recorded.

Audit Record

You have the record your auditor will ask for. Every interaction logged as structured, compliance-ready data. Timestamped. Searchable. Exportable. The documentation the EU AI Act, GDPR, and your own governance framework require — generated automatically, continuously, not reconstructed under pressure.

Policy Enforcement

Your AI policy has an enforcement layer. A policy without observability is a document. PowerGrabber gives your policy teeth — not by restricting what people do, but by making what they do visible.

Compliance Evidence

Your compliance team can demonstrate, not just assert. There is a significant difference between telling a regulator that AI usage is governed and showing them the capture record that proves it. PowerGrabber produces the latter.

Full Record

You know exactly what is leaving your organisation through AI tools. Not approximately. Not based on assumption. A precise, structured, searchable record of every prompt, every interaction, every API call — from every endpoint, every browser, every AI application in use across your organisation.

How It Works

How PowerGrabber works.

ChromeFirefoxEdgeSafariOpera
  1. Install PowerGrabber on any macOS, Windows, or Linux machine.
  2. Install the PowerGrabber browser extension.
  3. Everything is captured to a database.
  4. The PowerGrabber dashboard gives complete visibility — who is using what, what is being sent, stats, alerts, and a full audit log.
  5. For organisations that need to go further, PowerGrabber logs to databases, S3, Git, and file systems.

OWASP AI Compliance — Coming Soon

OWASP Features

PowerGrabber will include built-in compliance monitoring mapped to the OWASP Top 10 for LLM Applications (2025) and the OWASP Top 10 for Agentic Applications (2026).

LLM02 — Sensitive Information Disclosure

Detect credentials present in AI traffic. Map data flows from sensitive internal systems (healthcare, finance, HR) to AI provider endpoints. Flag API keys exposed in URL parameters. Your monitoring catches disclosure risks from HTTP metadata alone.

LLM03 — Supply Chain

Track which domains serve AI models and artifacts. Detect outdated SDK versions from User-Agent headers. Flag traffic to unknown or unapproved AI endpoints. Know when a new AI dependency appears in your organisation.

LLM06 — Excessive Agency

Monitor request volume per AI tool against established baselines. Detect when tools contact unexpected endpoint types or access APIs outside their normal scope. Track how many AI tools are active simultaneously across your organisation.

LLM10 — Unbounded Consumption

Track request rates per provider. Monitor rate-limit header consumption in real time. Detect 429 rate-limit responses. Project quota exhaustion. Identify denial-of-wallet patterns — sudden spikes in expensive API calls before the invoice arrives.

PowerGrabber will assess 9 of 20 OWASP AI items directly from HTTP metadata, provide supporting evidence for 3 more, and honestly report 8 as NOT ASSESSABLE — because knowing where your coverage ends is as valuable as knowing where it begins.

Teams

Built for the teams who need it.

Compliance and GRC

Continuous, automated capture of LLM interactions across the organisation. Audit-ready records without manual effort.

Security and IT

Complete visibility into AI tool usage across every endpoint. Shadow AI surfaced. Usage attributed. Anomalies identifiable.

Legal and Privacy

Documentation of AI data flows for GDPR, EU AI Act, HIPAA, and emerging AI regulatory obligations.

Engineering and DevOps

Full observability into LLM API usage — including developer tools like Claude Code and Cursor — for governance, cost attribution, and compliance.
