For beginners

Start with what you have

OSINT means collecting public information from lawful, safe sources and checking it carefully. You do not need to know a tool name.

Do you have a file or a link?

Check it on this device without opening the link or running the file. One screen for addresses, messages, file structure, and n8n workflow files.

Open quick checks

Step-by-step flows for an image, a claim, a domain, or an IP are on the workflows page.

Three steps in every investigation

  1. 01

    Define the question

    Write what you want to learn in one sentence. Separate the person, place, date, and claim.

  2. 02

    Start with the safest flow

    Use open and passive sources first. Do not sign in to suspicious links or run unknown files.

  3. 03

    Check with a second source

    Do not trust one result. Note the date, earliest source, and independent evidence that supports it.

Your first 10-minute practice

Check one news headline in two sources

Copy the headline, find the earliest source, compare publication dates, and note whether an independent source supports it. Before writing 'verified,' record what is still missing.
