Groups

Heatmap is a tool to help qualitative researchers identify and curate significant moments from large corpuses of recorded conversation audio.

Each ribbon represents a conversation,and each tile represents a speaker turn. The brightness of each tile represents its 'salience,' which can be scored by several transparent and tunable LLM parameters based on research by Wonjune Kang and Brandon Roy.

Brighter orange and yellow tiles may signal the presence of:

A coherent narrative
Emotional significance
Strong opinions
Sincere, vulnerable expression

Accordingly, dimmer purple and blue tiles tend to denote the absence of these traits—'filler' such as introductions, affirmations, or single-word interjections.

Interface

Hover over any tile to see a one-line preview of the speaker turn it represents. Click to reveal the speaker turn in full, with an option to play associated audio.

Use a universal search bar to query the entire corpus with any word or phrase, either by keyword or semantic similarity.

Select any moment from any conversation—a speaker turn, or a specific phrase or word within a speaker turn—and click the More like this button, which searches the rest of the corpus for semantically similar content.
