# How to Vibe Code Your Own Wudpecker (and Stop Paying for It)

> AI meeting assistant and knowledge-extraction tool

- Verdict: **Serious undertaking** (35/100 vibecodeable)
- Estimated effort: 6+ months of part-time work

## Verdict

Build a personal subset with a manual audio upload flow instead of automated bots, or keep paying if you need live calendar notetakers.

The core software engineering hurdle of Wudpecker is not the summarization or the UI—those are standard LLM wrappers. The true engineering nightmare is building and maintaining headless browser bots (Puppeteer/Playwright or custom WebRTC injectors) that can reliably launch, bypass waiting rooms, capture high-quality audio streams, and cleanly exit Zoom, Google Meet, and Microsoft Teams calls without crashing or getting IP-banned. A solo developer can easily vibe-code a web dashboard that transcribes uploaded audio files via Whisper and formats notes with Claude, but automating live conference bots requires dealing with relentless anti-bot updates from tech giants. If you want a personal tool, scope out the live bots entirely and build an audio upload utility.

### What you can't replicate

- Resilient headless meeting bots that automatically join live enterprise conference rooms
- Zero-friction OAuth integrations and calendar listeners across three major video platforms

## What it does

An AI meeting assistant that automatically joins online meetings across Zoom, Google Meet, and Microsoft Teams to transcribe and generate tailored, structured notes, summaries, and action items.

### Core features

- Calendar synchronization (Google Calendar / Outlook)
- Automated virtual bot orchestrator for Zoom, Google Meet, and Teams
- Multi-language speech-to-text transcription
- Custom prompt and template formatting for meeting notes
- Conversational 'Ask AI' RAG interface over past meetings
- Export integrations to Slack, Notion, and HubSpot

- Pre-seed round (October 2023)
Investors: Trind VC, Accelerace, Sofokus Ventures

Founded 2022.
Team size: Early-stage startup (~3 co-founders).

## The hard parts

- Headless recording bot stability (managing Puppeteer/Playwright WebRTC media streams across Zoom, Meet, and Teams without getting blocked or crashing)

## How to vibe code Wudpecker

### Prerequisites

- Node.js (free): Required runtime for backend services, scraping bots, and frontend tooling.
- GitHub (free): Source control and CI/CD triggers.
- OpenAI API Key (Usage-based (~$0.006/min)): Powers Whisper transcription and GPT-4o meeting summarization.

### Recommended AI tools

- Claude Code: Best-in-class agentic coding CLI for scaffolding full-stack apps and debugging complex asynchronous data pipelines.
- Cursor: Provides an AI-native editor interface for rapid front-end component tuning and prompt template editors.

### Stack

- Frontend: Next.js
- Backend: Next.js API Routes / Node.js worker
- Database: Neon
- Auth: better-auth
- Payments: Stripe
- Other: OpenAI API, Vercel AI SDK

### Hosting

- Vercel (Hosting the Next.js frontend and serverless API functions.): $0-20/mo
- Fly.io (Running persistent headless browser recording workers and WebRTC capture containers.): $5-15/mo

### Build guide

1. **Project Scaffolding & Database Schema** — Initialize the Next.js application with TypeScript, Tailwind CSS, and configure the Neon database connection via Drizzle ORM.

```
Scavenge a complete Next.js project using Next.js, Tailwind CSS, and Drizzle ORM configured for Neon PostgreSQL. Create database schemas for Users, Meetings, Transcripts, and CustomPrompts. Include a robust better-auth setup supporting email and password login. Implement strict TypeScript types and clean error boundaries across all server actions.
```

2. **Audio Upload & Transcription Pipeline** — Build an audio upload endpoint that interfaces with the OpenAI Whisper API to process recordings and store timestamped transcripts.

```
Build an audio upload interface and API route in Next.js that accepts MP3/WAV files up to 2 hours. Send the file payload to the OpenAI Whisper API with timestamp chunks enabled. Store the resulting raw transcript in the Neon database linked to a Meeting record. Implement a background processing status indicator with polling or server-sent events.
```

3. **LLM Summarization & Custom Prompt Engine** — Integrate the Vercel AI SDK to structure raw transcripts into user-defined templates and tables.

```
Implement a summarization engine using the Vercel AI SDK and OpenAI API. Create a prompt builder UI where users can save custom templates, vocabularies, and instructions. When a meeting transcript is selected, execute a structured extraction call that formats the output into clean markdown sections, executive summaries, and action item tables.
```

4. **Ask AI Conversational Interface** — Add a RAG-backed chat interface to query insights across all stored meeting records.

```
Build an 'Ask AI' drawer component in the meeting details view. Using vector embeddings or context chunking over Neon database meeting records, implement a chat endpoint that answers user queries citing specific moments in past meeting transcripts. Use streamText from the Vercel AI SDK for real-time response rendering.
```

5. **Calendar & Integration Settings** — Set up calendar sync placeholders and integration toggles for Slack, Notion, and HubSpot.

```
Create a settings dashboard allowing users to connect Google Calendar via OAuth, manage custom vocabulary lists, and configure outbound webhook integrations to push meeting notes to Slack and Notion. Write mock service handlers for each integration to verify payload transformations.
```

### Cost vs paying

**Starting costs (one-time):**

- Custom domain registration: $12 one-time
- Total: $12 one-time

**Ongoing costs (monthly):**

- Vercel / Fly.io Hosting: $15/mo
- OpenAI Whisper & LLM API Usage: ~$10/mo
- Total: ~$25/mo

- Paying for the SaaS instead: $32/mo (Pro tier)
- Build time: 60-80 hours
- AI tool credits: $20/mo (Claude Pro)
- Break-even: N/A (Built for personal control and privacy)
