Audio knowledge, distilled

Turn audio into searchable knowledge.

Upload podcasts, lectures, interviews, or meetings. Echograph transcribes them, indexes every sentence, and lets you ask questions, generate notes, and explore concepts.

Semantic search

Search by meaning, not just keywords. Powered by vector embeddings over every chunk of your transcripts.

Chat with citations

Ask questions across one or many episodes. Every answer comes with timestamped sources you can click.

Study tools

Generate summaries, notes, flashcards, MCQs, short-answer questions and interview prep — all grounded in the transcript.

Knowledge graph

Automatically extract people, organizations, technologies and concepts, and see how they connect.

Timestamped transcripts

Click any line to jump the audio there. Speaker labels when the model can identify them.

Exports

Download transcripts, notes, flashcards, MCQs and analytics as PDF or CSV.
