Product Tour

Aural is an AI-powered interview platform that conducts structured interviews autonomously. You design an interview, share a link, and Aural's AI handles the conversation — asking questions, probing with follow-ups, and generating detailed analysis when the session is complete.

Design Your Interview

Describe what you want to learn in plain language. The AI generates a complete interview with questions, assessment criteria, and recommended settings — or build one manually with the flexible editor.

Customize questions by type: open-ended, single/multiple choice, live coding with Monaco editor, or whiteboard drawing with Excalidraw.

Configure & Share

Fine-tune interview settings — AI personality, tone, follow-up depth, language, and communication channels (chat, voice, video). Control access with public shareable links or invite-only mode.

Practice Before Interviews

Turn any existing interview into a focused practice workspace. Add role context, rehearse by voice, get streamed coaching feedback after every answer, generate suggested answers from the JD/resume context, and track practice runs separately from real candidate sessions.

Invite Candidates

Add candidates one at a time, bulk-import from an Excel spreadsheet, or upload PDF resumes and let AI extract the details. Each candidate gets a unique invite link.

Create candidate form with name, email, education, and resume upload

_{Add a candidate manually or extract from resume}

Import by Resumes dialog — upload PDFs and parse with AI

_{Batch-import from PDF resumes}

Candidate Experience

Candidates complete a pre-interview checklist (photo capture, microphone test, screen sharing) and then enter the live session.

Conduct the Interview

Share a link and candidates join via chat, voice, or video. The AI adapts in real time — adjusting follow-up depth, tone, and direction based on responses.

Built-in coding and whiteboard modes for technical interviews:

Coding question — Monaco editor with language selector

_{Coding questions with Monaco editor}

_{Whiteboard questions with Excalidraw}

Anti-Cheating

Enable anti-cheating mode to enforce camera, microphone, and screen sharing. The system monitors tab switches, blocks external paste, and detects multi-monitor setups — all logged in a per-session integrity report.

Page departure detected warning during interview session

_{Real-time violation warning}

Integrity log showing page departures and external paste attempts

_{Per-session integrity log}

Analyze Results

Every completed session produces an AI-generated report with per-question scores, key highlights, and areas for improvement.

_{Per-question evaluation}

Assessment scores across multiple dimensions

_{Multi-dimensional assessment scores}

Dashboard & Team Management

Track all your interviews, sessions, and candidates from a unified dashboard. Organize work across organizations and projects with role-based access.

Common Use Cases

Technical hiring — coding and system design interviews with built-in editor and whiteboard
User research — in-depth research interviews with AI follow-ups that surface deeper insights
Behavioral interviews — voice-based conversations that feel natural and scale to hundreds of candidates
Interview practice — candidates practice with AI feedback before their real interview

Key Modules

Module	Location	Responsibility
App Router	`src/app/`	Pages and layouts organized into route groups: `(auth)` for login/register, `(dashboard)` for the main app, `(docs)` for documentation, `i/` for public interview links, and `practice/` for practice sessions.
tRPC Routers	`src/server/routers/`	Typed API layer handling interviews, sessions, analysis, organizations, projects, candidates, and access control.
REST API Routes	`src/app/api/`	Endpoints for AI operations (chat, generate, refine, summarize), practice feedback/hints/follow-ups, voice token/save/TTS, auth, session lifecycle (complete/leave), and file uploads.
Developer API (v1)	`src/app/api/v1/`	Full REST API for programmatic interview management — CRUD for interviews, questions, sessions, candidates, publish, and usage. Authenticated via `dlv_` API keys with rate limiting. OpenAPI 3.1 spec at `/api/v1/openapi.json`.
AI Provider Registry	`src/lib/ai/`	Pluggable LLM system with a provider registry, per-task model selection, and prompt templates for interviewing, generation, and report summarization.
Voice Relay	`server/`	Standalone WebSocket servers that proxy audio between the browser and speech-to-speech APIs (Volcengine Doubao or Azure OpenAI Realtime).
Practice / Prep Module	`src/app/(dashboard)/practices/`, `src/app/practice/`, `src/components/prep/`, `src/lib/prep/`, `src/server/routers/prep.ts`	Interview practice workspace with JD/resume context, voice or text answers, streamed feedback, suggested answers, follow-up coaching, practice attempt history, and resumable sessions.
Components	`src/components/`	React components split by domain — `session/` (chat/voice/video UI, anti-cheating), `interview/` (builder, question cards), `auth/`, `layout/`, and `ui/` (shadcn primitives).
Supabase Layer	`src/lib/supabase/`	Client/server/admin helpers for database access, auth, and storage. Row-Level Security enforces data isolation per user and organization.

Deployment

You can use Aural as a managed cloud service or self-host the entire platform on your own infrastructure.

Cloud Hosted

The fastest way to get started. No setup required — sign up and start creating interviews immediately.

Get started at aural-ai.com →

Fully managed infrastructure
Automatic updates and maintenance
Built-in voice relay servers
No LLM keys or Supabase setup needed

Self-Hosted

Run Aural on your own servers for full control over data, configuration, and customization.

Prerequisites

Node.js 18+ and npm
Supabase project (cloud or local via supabase start)
LLM API key — at least one of: OpenAI, Google Gemini, Kimi (Moonshot), or MiniMax
Voice relay credentials — Volcengine Doubao (primary) or Azure OpenAI (backup), if you want voice interviews or voice practice

1. Clone and Install

git clone https://github.com/1146345502/aural-oss.git
cd aural-oss
npm install

2. Set Up Supabase

Option A — Supabase Cloud

Create a project at supabase.com
Copy your project URL and keys

Option B — Local Supabase

Requires Docker running on your machine.

npx supabase start

This pulls the Supabase Docker images, starts all services, and automatically applies all migrations from supabase/migrations/. When it finishes, it prints connection details including the API keys (look for the Publishable and Secret keys).

3. Run Migrations

Local Supabase: migrations are applied automatically during supabase start — skip this step.
Supabase Cloud: push the migrations to your remote project:

npx supabase db push

Or apply migrations manually from supabase/migrations/.

4. Configure Environment

cp .env.example .env.local

Edit .env.local with your credentials. At minimum you need:

Supabase URL and keys
One LLM provider API key (OPENAI_API_KEY recommended for the main app; GEMINI_API_KEY recommended for relay summarization and fallback generation)
Voice credentials only if you want voice interviews or voice practice (DOUBAO_* for the recommended relay, or AZURE_OPENAI_* for the backup relay)

Local Supabase key mapping — map the keys from supabase status output to your .env.local:

Supabase CLI output	`.env.local` variable
Project URL (`http://127.0.0.1:54321`)	`NEXT_PUBLIC_SUPABASE_URL` and `SUPABASE_URL`
Publishable key	`NEXT_PUBLIC_SUPABASE_ANON_KEY` and `SUPABASE_ANON_KEY`
Secret key	`SUPABASE_SERVICE_ROLE_KEY`
Database URL	`DATABASE_URL`

5. Start Development

# Start the Next.js dev server
npm run dev

# Start the primary voice relay (Volcengine Doubao)
npm run dev:voice

# Or start the backup voice relay (Azure OpenAI Realtime)
npm run dev:openai-voice

Open http://localhost:3000/login to sign in, or http://localhost:3000/register to create a new account.

Practice / Prep Module

The practice module lets interview authors and candidates rehearse against an interview without creating real candidate sessions. It is intentionally part of the OSS app and does not depend on private billing or usage-control infrastructure.

Area	Location	Notes
Dashboard list	`src/app/(dashboard)/practices/`	Cross-interview practice history and quick access.
Interview tab	`src/app/(dashboard)/interviews/[id]/edit/prep/`	Per-interview Practices tab with stats, filters, context, and launch controls.
Practice session	`src/app/(dashboard)/interviews/[id]/prep/`, `src/app/practice/[id]/`	Text or voice rehearsal flow with resumable attempts.
UI components	`src/components/prep/`	Context drawer, answer cards, streamed feedback, suggested answers, follow-ups, and voice input.
API layer	`src/server/routers/prep.ts`, `src/app/api/prep/`	tRPC data mutations plus streaming feedback, follow-up, hint, and leave endpoints.
Data model	`supabase/migrations/004_interview_prep.sql`	Adds interview context fields plus `prep_sessions` and `prep_attempts` tables with RLS.

Practice feedback uses the same LLM provider chain as interview generation. Voice practice also uses the voice relay and Doubao TTS settings from .env.local; answer audio is stored in the existing private recordings bucket.

AI Provider System

Aural uses a pluggable LLM provider architecture. You need at least one provider configured. The system auto-selects the first available provider in this order: OpenAI > Gemini > Kimi > MiniMax.

Providers

Provider	Env Variable	Default Model	Get API Key
OpenAI (recommended)	`OPENAI_API_KEY`	`gpt-4o-mini`	platform.openai.com/api-keys
Google Gemini	`GEMINI_API_KEY`	`gemini-3.1-flash-lite`	aistudio.google.com
Moonshot Kimi	`KIMI_API_KEY`	`moonshot-v1-8k`	platform.moonshot.cn
MiniMax	`MINIMAX_API_KEY`	`MiniMax-Text-01`	platform.minimaxi.com

You can also use any OpenAI-compatible API (e.g., local models via Ollama or LiteLLM) by setting OPENAI_BASE_URL.

How LLMs Are Used

Aural uses LLMs for several distinct tasks, each selecting the best available model:

Task	What It Does	OpenAI Model	Gemini Model	Kimi Model	MiniMax Model
Chat interviewing	Powers the AI interviewer during live sessions — asks questions, generates follow-ups, adapts tone	`gpt-4o-mini`	`gemini-3.1-flash-lite`	`moonshot-v1-8k`	`MiniMax-Text-01`
Interview generation	Generates a complete interview (questions, criteria, settings) from a plain-language description	`gpt-4o-mini`	`gemini-3.1-flash-lite`	`moonshot-v1-8k`	`MiniMax-M2.1-lightning`
Question refinement	Improves or refines existing interview questions based on feedback	`gpt-4o-mini`	`gemini-3.1-flash-lite`	`moonshot-v1-8k`	`MiniMax-M2.1-lightning`
Practice coaching	Scores practice answers, streams feedback, generates follow-up coaching, and suggests improved answers	`gpt-4o-mini`	`gemini-3.1-flash-lite`	`moonshot-v1-8k`	`MiniMax-M2.1-lightning`
Report & analysis	Generates post-interview reports with per-question scores, highlights, and improvement areas	`gpt-4o`	`gemini-3.1-flash-lite`	`kimi-k2.5`	`MiniMax-M2.1-lightning`

Report generation uses a higher-capability model when OpenAI or Kimi is configured because it requires synthesizing an entire conversation into structured analysis. Chat interviewing uses each provider's default model unless overridden per-interview in the settings. Interview generation and practice coaching use a fallback chain, so configuring more than one provider improves resilience.

Voice Relay

Aural supports real-time AI voice interviews via WebSocket relay servers. Two relay implementations are provided.

Recommendation: We strongly recommend using Volcengine Doubao as your primary voice relay. It delivers a noticeably better interview experience than the OpenAI Realtime model — lower latency, more natural speech-to-speech flow, superior Chinese language support, and built-in server-side auto-reconnect for reliability. The OpenAI relay is provided as a backup for environments where Volcengine credentials are unavailable.

Primary (Recommended): Volcengine Doubao (`server/voice-relay.ts`)

The recommended voice relay for production use. It provides full-featured Speech-to-Speech capabilities with per-question interview flow, LLM-powered context summarization, native Chinese language support, and automatic server-side reconnection (up to 3 retry attempts with backoff) for resilient voice sessions.

npm run dev:voice          # starts on port 8766

Required env vars: either DOUBAO_APP_ID + DOUBAO_ACCESS_TOKEN, or DOUBAO_API_KEY.

Recommended supporting env vars:

GEMINI_API_KEY for the relay LLM default (gemini-3.1-flash-lite)
RELAY_LLM_PROVIDER=gemini
RELAY_LLM_MODEL=gemini-3.1-flash-lite
NEXT_PUBLIC_VOICE_RELAY_PRIMARY=voice
DOUBAO_ASR_RESOURCE_ID=volc.seedasr.sauc.duration
DOUBAO_TTS_RESOURCE_ID=seed-tts-2.0
DOUBAO_TTS_PCM_SAMPLE_LAYOUT=int16le

Backup: Azure OpenAI Realtime (`server/openai-voice-relay.ts`)

An alternative relay using Azure OpenAI's Realtime API (gpt-realtime-1.5 by default). Use this when Volcengine credentials are unavailable or for English-only deployments. Note that the OpenAI relay may have higher latency and less natural conversational flow compared to Volcengine.

npm run dev:openai-voice   # starts on port 8767

Required env vars: AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_API_KEY, AZURE_OPENAI_DEPLOYMENT

Tip: You can run both relays simultaneously. The frontend uses NEXT_PUBLIC_VOICE_RELAY_PRIMARY to choose the first relay and automatically falls back to the alternate relay if the primary cannot connect.

Developer API

Aural includes a full REST API for programmatic access to interviews, questions, sessions, and candidates. Use it to integrate Aural into your existing workflows, automate interview creation, or build custom integrations.

Authentication

All API requests require a developer API key in the Authorization header:

Authorization: Bearer dlv_your_key_here

Create and manage API keys from Settings > API Keys in the dashboard.
