Tech Stack + Features

Frameworks

• Next.js – React framework for building performant apps with the best developer experience

Platforms

• Vercel – Easily preview & deploy changes with git
• Upstash - Serverless Data Platform (here using serverless Redis for rate limiting)

UI

• Tailwind CSS – Utility-first CSS framework for rapid UI development
• Framer Motion – Motion library for React to animate components with ease
• ImageResponse – Generate dynamic Open Graph images at the edge
• HeadlessUI - Completely unstyled, fully accessible UI components, designed to integrate beautifully with Tailwind CSS

Code Quality

• TypeScript – Static type checker for end-to-end typesafety
• Prettier – Opinionated code formatter for consistent code style
• ESLint – Pluggable linter for Next.js and TypeScript

Miscellaneous

• FFMPEG.WASM – Transcode video/audio files
• React Webcam - Webcam component for React
• Stripe Gradient Animation - @jordienr released a Mesh Gradient that uses WebGL and animates a beautiful gradient

How it all works

Liftoff uses FFmpeg to transcode the raw video into MP3. Chrome, Safari, and Firefox all record with different codecs, and FFmpeg is great for standardizing them.

We then send the audio directly to be transcribed by OpenAI's Whisper endpoint, and then stream feedback from the edge using OpenAI's gpt-3.5-turbo.
