Undertone is a macOS app that listens along to your calls. When a code name, acronym or internal project comes up, a small panel beside the call explains it from your team's own Slack, Notion and Jira. When someone asks you a question, it brings up the facts you need. Afterwards you get the recap, your tasks and a follow-up draft. Calls are transcribed on your Mac and no bot joins the meeting.

Could you build this?
Partial The Slack, Notion, and Jira integrations and summary UI are buildable, but reliable real-time call transcription and capturing audio on macOS adds system-level and latency challenges.
What it would actually take: Use macOS ScreenCaptureKit or audio-driver APIs to capture call audio with user consent, feeding a streaming speech-to-text service with diarization. A retrieval layer over OAuth-connected Slack, Notion, and Jira indexes provides jargon definitions with low latency. Hard parts include low-latency Swift and native audio work, privacy and consent compliance across jurisdictions, and tuning retrieval to avoid wrong explanations in live calls.
