Heify processes voice recordings — calls, meetings, interviews, training sessions — and converts them into structured data, quality metrics, and actionable insights. It’s not just a transcription tool: it’s a full conversation analysis system that listens, understands, extracts, evaluates, and reports — all configurable without code.

​
The Heify Pipeline

Every recording flows through a modular pipeline. Each component is independent and optional — combine them as your use case requires.

Configurations

The core template. Defines what to extract from audio: structured fields, AI summary, custom vocabulary, language, and webhooks. Required for every transcription.

Evaluators

Quality-scoring rubrics. Define weighted criteria — Heify scores every conversation against them automatically and flags critical failures.

Participants

Person profiles — support agents, job candidates, salespeople, or any individual. Attach a participant to track their performance across transcriptions over time.

Transcriptions

The result. Full transcript with speaker labels, extracted fields, AI summary, evaluation score — all in one object.
Only a Configuration is required. Evaluators and Participants are optional layers you activate when you need quality scoring or per-person performance tracking.

​
Two Ways to Use Heify

​
Heify API

A programmatic interface for developers. Integrate transcription, extraction, quality scoring, and analytics directly into your applications and workflows. Key capabilities:
  • Manage all modules — create, update, and delete Configurations, Evaluators, and Participants programmatically
  • Submit audio via URL or direct upload — public URL or presigned S3 upload
  • Extract structured fields from conversations using AI — define any schema you need
  • Automatic AI summaries with custom instructions per configuration
  • Quality scoring — attach an Evaluator to score every call automatically
  • Per-person tracking — attach a Participant (agent, candidate, salesperson) to build individual performance analytics
  • Webhooks — get notified the moment a transcription completes or fails
  • Analytics endpoints — AI-powered corpus analysis across configurations, evaluators, and participants

​
Heify Sandbox

A browser-based interface for business teams, QA analysts, and anyone who wants to explore Heify without writing code. Key features:
  • No-code configuration builder with extraction field templates and quick-action shortcuts
  • Drag & drop audio upload or paste a URL — results appear in minutes

API Overview

The Heify API is organized around these principles:
  • JSON-based: All requests and responses use JSON format
  • HTTP methods: All endpoints use POST
  • API Key authentication: Secure access with API keys via the x-api-key header
