Resource library

OSINT tools with context, limits, and safer use notes.

This English view turns the Turkish archive into a global research index. It keeps the focus on what a source can help check, where it can mislead, and how it should be used in a report.

Start with search, narrow by shelf; every card carries a risk note and a last-checked date.

Quick discovery

What are you looking for first?

Pick one of five segments; the filter on the right narrows to that area.

For news claims, image, or video verification: reverse search, earlier copies, and context checks.

Open the segment

Start with source type

A search engine, official registry, archive, or threat feed answers different questions.

Write down limits

A result can be useful and still incomplete, old, copied, or out of context.

Move to reporting

Useful research becomes clearer when evidence and interpretation are written separately.

Collections

Find the right source family first.

Move notes into a report

Search and meta-search

Search and archives

Start with search engines, archived pages, cached copies, and older public records.

6 entries

Domain and DNS intelligence

Domains and web traces

Check domains, DNS, certificates, hosting context, and passive infrastructure signals.

9 entries

Image and reverse-image search

Images and video

Look for earlier uploads, frames, visual clues, and publication context.

6 entries

Location and map verification

Maps and location

Compare terrain, streets, satellite imagery, sun position, and public map traces.

7 entries
