About this app

Decipher is an AI-powered tool for analysing media content. It assesses the journalistic quality and the persuasive potential of texts, web articles, YouTube videos and podcasts.

16 CRITERIA. TWO GRADES.

The tool systematically examines the content you paste against eight recognised journalistic principles (from the German Press Code / UK Editors' Code of Practice) and eight dimensions for detecting persuasive techniques.
The result is reasoned, evidence-based pointers across 16 criteria, distilled into two grades on a scale of 1 to 6 — a basis for forming your own view and for discussion. The methodology is fully transparent at https://decipher.media/methodology.

ONE METHOD. SIX INPUTS.

What you can analyse:
• Text you paste
• Articles by link
• YouTube videos (incl. optional transcription)
• Podcasts (incl. optional transcription)
• Photos & documents (text is extracted)

MORE DEPTH, WHEN YOU NEED IT

Where the first assessment isn't enough, three optional deep-dive modules are available: a fact check that verifies each checkable claim individually against external sources; a source check that opens every linked source and compares it against the article's statements; and video source detection that captures logos, quotes and documents shown in the video with timestamps and finds the original sources.

OUR MISSION

"Critical media consumption shouldn't be a privilege. Decipher puts a tool in people's hands to systematically examine the quality of media content — and with it, the influence on their own thinking. We don't provide an opinion; we provide the basis for forming one."

DISCLAIMER

Decipher can make mistakes. Its analysis results are for informational purposes and do not constitute legal or journalistic expert opinions. If you spot an error, please help us with a quick note. The final assessment of media content is yours to make.
