Why Dossier

Structure your listening. Keep the insights.

Podcasts are rich with ideas but impossible to reference. Dossier gives every episode a structure you can navigate, search, and cite.

◆

Structure, not summaries

Summaries flatten. Dossier preserves the episode's structure with labeled sections, so you can navigate to the argument, the technique, or the narrative that matters to you.

☑

People and concepts linked

Speakers, tools, and concepts are automatically resolved to Wikipedia and Google Knowledge Graph. Click any name to learn more. Know who's talking and what they're referencing.

▶

One click to the source

Every section is timestamped. Click to hear the original context. No more scrubbing through an hour of audio to find the 30 seconds you need.

Works across genres

One tool for every podcast in your queue

From NPR investigations to tech deep-dives, Dossier adapts its analysis to the content.

Mission

Make spoken knowledge as accessible as written knowledge.

I spent 8+ years in EdTech building search and recommender systems for a research platform used by 95% of the world's libraries. I've seen firsthand how much harder it is to find, verify, and cite information when it lives in audio instead of text.

Podcasts are where some of the best thinking happens now. But you can't search a conversation, you can't skim an interview, and you definitely can't cite "that thing someone said around minute 40." I built Dossier because I kept losing great ideas to the linear nature of audio.

I care about combating misinformation and making information more accessible. Dossier is how I'm doing that for spoken-word content -- showing you who said what, linking to external knowledge, and always keeping the source one click away.

PRINCIPLES
Trust before convenience

A fast output that misrepresents the source is worse than no output. Every takeaway traces back to who said it and when. The original audio is always one click away.

Evidence does the persuading

We connect speakers and concepts to external knowledge -- Wikipedia, academic databases, public records. We show you the context and let you decide what to trust.

Structure, not summaries

Summaries flatten nuance. Dossier preserves the episode's natural structure and lets you navigate it on your terms. We add organization, not opinion.
