Analyze sales calls with Whisper transcription, GPT-4o, Airtable and Slack

Submit a call recording and get a full AI-powered analysis delivered automatically. Your recording is transcribed with OpenAI Whisper, then GPT-4o breaks down sentiment, objections, buying signals, deal risk, next steps, and a ready-to-send follow-up email. Results are saved to Airtable, posted to your Slack channel, and shown to the rep as a rich summary page the moment the form is submitted. This workflow is built for sales teams, revenue operations managers, and sales coaches who want consistent call intelligence without manual review.

What This Workflow Does

- Automatic transcription — downloads your audio file and converts it to text using OpenAI Whisper, handling mp3, wav, and m4a formats - Deep AI analysis — GPT-4o reads the full transcript and identifies sentiment, deal risk, momentum, objections with direct quotes, and buying signals - Deal stage recommendation — suggests whether the deal should advance, stay, or retreat based on what actually happened on the call - Coaching feedback — generates one specific, actionable coaching tip for the rep based on their talk ratio and call behaviour - CRM-ready note — writes a professional 2–3 sentence note you can paste directly into any CRM - Follow-up email draft — generates a warm, personalised follow-up email referencing something the prospect actually said - Multi-channel delivery — saves the full analysis to Airtable, sends a summary to Slack, and shows the rep an HTML results page instantly
