Tejji

Tejji is a web productivity and OSINT utility platform offering a collection of free online tools including URL analysis, text processing, network utilities, and SEO analysis functions. For investigators who need quick, browser-based access to utility functions without installing software, Tejji provides a consolidated toolkit accessible from any device.

The platform's URL tools include link analysis, redirect chain checking, and URL decoding — useful for investigators analyzing suspicious links before clicking, tracing shortened URLs to their final destinations, or decoding obfuscated URLs encountered in phishing analysis or malware investigation. Understanding the full redirect chain of a URL reveals intermediate hosts that may expose additional infrastructure.

Text analysis tools on Tejji support character counting, case conversion, encoding/decoding (Base64, URL encoding, HTML entities), and text comparison — utility functions frequently needed during OSINT workflows when processing data from multiple sources. Encoding and decoding functions are particularly relevant in malware analysis, where encoded strings may hide command-and-control URLs or configuration data.

Network utilities include IP lookup, DNS query tools, and port checking — providing quick lookups without requiring command-line tools. For investigators working in browser-constrained environments or teaching OSINT techniques, browser-based network tools lower the barrier to common investigative tasks.

SEO analysis tools reveal page metadata, header structures, and keyword density — useful for understanding how a website presents itself to search engines, which can provide context about a site's purpose and legitimacy. Sites with heavily SEO-optimized content around suspicious terms may indicate spammy or malicious intent.

As a consolidated multi-tool platform, Tejji reduces the number of separate sites investigators must visit during a workflow, streamlining the documentation and tab management challenges inherent in complex investigations.
