ParcelProof: the customer's voice note says the box was empty

说明与用途

ParcelProof 将空盒子争议的准备时间从整整一晚缩短到几分钟，整合音频、文档和照片为结构化案例。

问题

Small online sellers lose disputes they could have won because evidence is scattered across courier tracking pages, invoices, photos, and WhatsApp voice notes, making it hard to compile a coherent case.

结果

ParcelProof reduces dispute resolution time from an evening to a few minutes, enabling sellers to present a structured, evidence‑based case and avoid unnecessary refunds.

工作流

• Create a case and upload evidence (PDFs, screenshots, CSVs, audio).
• ElevenLabs Scribe transcribes audio with speaker labels and timestamps.
• Documents and scans are parsed with PDF.js and Tesseract to produce source‑labelled text.
• Data is stored in MongoDB Atlas (GridFS).
• Mastra workflow runs seven typed steps: verify‑case, load‑evidence, build‑chunks, extract‑events (Gemma), ground‑events, compare‑evidence (Gemma), ground‑findings‑and‑persist.
• Seller reviews findings, confirms, corrects, or dismisses each one.
• Gemma writes a 45‑second briefing script based on confirmed data.
• ElevenLabs TTS reads the briefing with character timestamps.
• A synced player and PDF report are generated for the reviewer.

证据

ParcelProof turns that evening into a few minutes. You drop everything into a case, voice note included.

来源

ElevenLabs Scribe transcribes the audio with speaker labels and timestamps, so what the customer said becomes evidence you can quote.

来源

Gemma writes a 45-second briefing from only what you confirmed, and ElevenLabs reads it to you in English or Hinglish while the transcript highlights along with the voice.

The first time you sign in, a narrated tour walks through one example case. The narration is ElevenLabs too, and you can skip it.
