Tattle describes a free, open-source Mac app that transcribes calls, maps the conversation, and flags claims for fact-checking as they are spoken.

- Worth noticing
- The page estimates about four cents in Jev calls per one-hour show, based on a test conversation; claim-heavy shows cost more.
Field notes
The described input combines the user's microphone with audio played by the Mac, which the site says lets it work across call apps. It describes speaker naming, timeline labels for topic and conversational tone, and a separate web-research pass that adds sources to flagged claims. The page estimates roughly 2,000 Jev judgments and about four cents per hour, based on a test conversation; it also says local transcription requires macOS 26 or later, despite listing macOS 14.2 as the app's minimum.
