Playback and the transcript, together. Return to the recording when the wording matters.

Find a passage without starting over.

You do not have to replay the whole recording to find one point. Search for a word you remember or return to a moment you bookmarked, then listen with the transcript in front of you.

  1. During the conversation

    Bookmark a moment.

    Follow the live transcript and mark a point you want to revisit while you keep listening.

  2. When you return

    Search the transcript.

    Use a word you remember to find the relevant passage instead of listening from the beginning.

  3. When the wording matters

    Check against the audio.

    Listen again to confirm a name, number, or quotation before you use it.

02 / Put the conversation to work

Get a working note from the transcript.

When the conversation is over, use the transcript to make a summary, prepare notes, or answer a question before you write the follow-up.

Echo Chamber’s AI tools run locally. Ask for the key points or make a cleaner reading copy, then return to the recording whenever you need to check the result.

Shown in the app
