The Corrected Invoice in the investigation browser: the “corrected” invoice email, on a fictional webmail.

How it works

01 · Investigate

Browse a fictional web: storefronts, registries, reviews, records. Every site is a .test address that exists only here.

02 · Pin & cite

Pin the pages you rely on and keep notes as you go. A finding without evidence is only a guess; the Case is built so that every answer can be traced to a page.

03 · Answer & debrief

Answer in the expected format and get immediate feedback. The debrief explains each step and what a careful investigator would have checked.

First cases

Cases & modules

Let's OSINT trains open-source and fraud investigators on a closed fictional internet. You practice the real gestures (reading a domain record, checking who is behind a payment, dating a review wave) on material made for training.

  • Free modules to learn the method, starting with Domains & WHOIS Basics.
  • A free Case, The Corrected Invoice, to try a short investigation end to end.
  • Professional tracks are coming (insurance and payment fraud first), added to your account as they open.

Free during early access

The Foundations modules and every Case are free while Let's OSINT is in early access. No card needed. Create an account and your progress, notes and results are kept between sessions.
