Summary: CallSense is what a revenue-intelligence lead asks for: every uploaded call becomes a transcript, a summary, objections, competitor names, and a sentiment score — then managers search “pricing” or competitor X across the library. Whisper is not a fleet. The LLM is not a second DAG. Both are columns. Insert the audio. The rest follows. pip install pixeltable.
The Product#
- Store the recording with
call_id, rep, account - Transcribe on insert
- Extract summary, pain points, competitors, sentiment (1–10)
- Search past calls by what was said
The Whisper-only tutorial is OpenAI Whisper integration. Parallel batching at scale is a different post. This one is the call object: audio plus structured judgment.
The Stitch You Delete#
S3 for the WAV. A worker that calls Whisper. Another worker that calls GPT. A CRM field you paste into. Postgres plus pgvector for “find the pricing objection.” Pixeltable is one table. The Whisper post already argued transcription as a column. CallSense is that column plus the extract and the index.
The Receipt#
“Find calls where they brought up pricing or competitor X” is search_calls('pricing concerns') or search_calls('Acme'). The embedding is on the transcript; the JSON is for the manager’s card. Same file on Cloud: pxt db update → pxt schema update → pxt service update.
What This Is Not#
Not Gong. Not diarization as a product. Not a CRM. Auth and deal TPV stay where they are. The recording graph — bytes, transcript, extract, search — is the table.
People Also Ask#
Which Whisper? model='base' matches the homepage. Swap the model string; the column stays.
Why JSON in a UDF? Gemini returns text. parse_insights is the typed object you query. If the model emits garbage, you still have the raw column.
How do I go to Cloud? Same app.py. PIXELTABLE_API_KEY, pxt://org:db, then db → schema → service.
Listen Once, Query Forever#
Insert the MP3. Read the transcript. Search the library. Do not stand up a transcription fleet to get there.
