CRM Update Diff Builder

Keeps your CRM current with a reviewable, quote-backed diff. Paste in the current CRM record (as JSON) plus new context (a call transcript, an email thread, or meeting notes) and it returns a structured, field-by-field diff of what should change: current value, proposed value, the exact quote that justifies it, and a confidence score, plus a one-line summary. It follows the diff-before-write pattern: every change arrives as a side-by-side proposal for a human or a separate write step to approve, so each update to the record is one you signed off on. Where Call Notes to CRM builds a fresh MEDDIC-shaped record from a transcript, this template starts from the record you already have, reasons about exactly what should change, and outputs an auditable diff rather than a full replacement record, which makes it the right gate in front of a live CRM write. Input: current record { "stage": "Discovery", "champion": null, "budget": null } plus a call transcript where the prospect says "I'll be the one pushing this internally" and "we've got about $40k set aside for this." Output: { "diff": [ { "field": "champion", "currentValue": null, "proposedValue": "prospect (self-identified)", "sourceQuote": "I'll be the one pushing this internally", "confidence": 0.8 }, { "field": "budget", "currentValue": null, "proposedValue": "$40,000", "sourceQuote": "we've got about $40k set aside for this", "confidence": 0.85 } ], "summary": "Champion and budget identified from call; stage unchanged, no evidence for a stage move." }
