The verdict: can you vibe code Notin?
You can build a fully functional personal medical transcription and note-structuring web tool over a couple of weekends, but compliance requirements like HIPAA and EHR integrations make public commercialization a heavy lift.
The core workflow of recording audio, piping it to Whisper, and prompting an LLM to output a structured JSON SOAP note is straightforward with modern toolings. The primary friction points are managing microphone permissions and stream stability in the browser, and designing strict JSON schemas so the LLM never invents medication dosages or patient symptoms.
Estimated effort: 2-3 weekends

Build guide
01Project Scaffolding and Database Schema
Initialize a Next.js project with Tailwind CSS and configure Turso SQLite to manage patient encounters and generated notes.
Create a new Next.js application using App Router, TypeScript, and Tailwind CSS. Install better-sqlite3 or Turso client libraries for local database interactions. Design a database schema with tables for 'encounters' (id, patient_name, audio_url, raw_transcript, soap_note_json, billing_codes, created_at). Set up basic layout wrappers with a clean clinical dashboard aesthetic using dark/light slate styling.02Audio Capture and Recording UI
Implement browser-based MediaRecorder API hooks to capture high-fidelity voice notes directly in the web app.
Build a React component for audio capture using the browser MediaRecorder API. Include start, pause, resume, and stop controls with a live waveform or timer indicator. Ensure the recorded audio blob can be previewed locally and submitted via FormData to our backend API endpoints. Handle microphone permission error states gracefully.03Transcription Integration
Connect the recorded audio endpoint to the OpenAI Whisper API to transcribe clinical dictation accurately.
Implement a Next.js API route that accepts an uploaded audio file (WebM or MP4), saves it temporarily, and calls the OpenAI Whisper transcription API. Include medical terminology prompting or instructions to ensure accurate spelling of clinical drugs and anatomical terms. Return the resulting text string to the frontend UI.04Clinical NLP and Structured Extraction
Pass raw transcripts through an LLM using strict JSON schema validation to extract SOAP notes and medical codes.
Build a backend processing function that takes the raw transcript text and sends it to an LLM with a strict system prompt and Zod schema validation. The output must parse into a structured JSON object containing: subjective, objective, assessment, plan, and suggested ICD/CPT billing codes. Handle cases where the LLM response fails validation by implementing automated retry logic.05Encounter Review and Export Dashboard
Create an interactive editor view for physicians to inspect, tweak, and export generated medical notes.
Create a dashboard interface in Next.js that lists past encounters and opens a detailed review view. The view should display editable text boxes for each section of the SOAP note (Subjective, Objective, Assessment, Plan) and a badge list of suggested billing codes. Add a copy-to-clipboard button and a PDF download export utility for clinical documentation convenience.

Vibe code Notin: FAQ
- Can you vibe code Notin yourself?
- Solid side project — 75/100 vibecodeable. You can build a fully functional personal medical transcription and note-structuring web tool over a couple of weekends, but compliance requirements like HIPAA and EHR integrations make public commercialization a heavy lift.
- How long does it take to vibe code Notin?
- 2-3 weekends — roughly 12-18 hours of hands-on time with an AI coding agent.
- How do you build your own Notin?
- Scoped to personal use: Next.js with Tailwind CSS and shadcn/ui components on the front, Next.js API routes / Server Actions behind it, Turso (SQLite at the edge for storing encounter transcripts and notes) for data. Follow the 5-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own Notin without being an expert?
- Use an AI coding tool (Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 2-3 weekends. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Notin instead of paying?
- About ~$30 one-time to start and ~$5-15/mo to run, versus ~$100-300+/mo (estimated enterprise/per-provider tier) for Notin. Break-even: Immediate if used personally.
- What stack should you use to vibe code Notin?
- Next.js with Tailwind CSS and shadcn/ui components; Next.js API routes / Server Actions; Turso (SQLite at the edge for storing encounter transcripts and notes); plus OpenAI Whisper API for audio transcription, OpenAI GPT-4o / Anthropic Claude for clinical JSON extraction.
