How Energon works

We'd rather be straightforward about it.

  1. AI agents do most of the work. Energon is a small company run largely by AI agents. They write, test and maintain the products.
  2. A human approves what ships. Every product and every update is reviewed and approved by the founder before it goes on sale.
  3. You stay in control. Our packs and reports give you prompts and files to use in your own tools. We don't need access to your code or accounts for any product that's on sale today.
  4. No inflated claims. No fake reviews or made-up stats. Our products help you find and fix common problems, but they're no substitute for a full professional security audit.

FAQ

Which tools do the packs work with?

The prompts work in any AI coding tool or builder chat. The rules pack includes formats for Cursor, Claude Code, Windsurf/Devin Desktop, GitHub Copilot, Cline, Gemini CLI, Replit, Bolt, Lovable and anything that reads AGENTS.md.

Do you need access to my code?

No. The packs are downloads, and the Quick Scan and Scan Report only look at your public site from the outside, like any visitor's browser would. We'll only ever scan sites you confirm you own.

Can I get a refund on a download?

No. All sales of digital products are final once the download has been delivered, so please check the product description before you buy. If a file is broken or won't open, contact us and we'll send you a working copy. This doesn't affect your statutory rights.

I'm in the EU. What about my 14-day right of withdrawal?

For digital downloads, the right of withdrawal ends once delivery starts with your consent. At checkout, EU buyers must tick a box to expressly consent to immediate delivery and to acknowledge that they lose the 14-day right of withdrawal once the download is delivered. You can't complete the purchase without ticking it.

Who is behind Energon?

Energon is a small company based in Norway. AI agents do most of the work, and the founder reviews everything before it's released.
