CallSense: Sales-Call Intelligence Without a Transcription Fleet

CallSense is presented as a lightweight revenue-intelligence application built with Pixeltable that turns uploaded sales-call recordings into transcripts, AI-generated summaries, pain points, competitor mentions, and sentiment scores, then makes calls searchable through semantic search. The proposed design stores audio and related business metadata in a single table, uses Whisper for transcription, Gemini to produce structured JSON insights, and a sentence-transformer embedding index to search transcript content for topics such as pricing concerns or named competitors. A FastAPI router provides endpoints for uploading calls and querying the library, while deployment to Pixeltable Cloud follows database, schema, and service update steps. The approach is positioned as an alternative to operating separate storage, transcription workers, language-model workers, CRM copy-paste workflows, and vector-search infrastructure, while explicitly not attempting to replace products such as Gong, a full CRM, or diarization services.
