BirdGO

Catch (the sounds of) them all!

BirdGO is an offline-first Progressive Web App that turns your surroundings into a bird-watching game. Hold up your phone, let it listen, and discover what birds are singing nearby — all without sending audio to any server.

How it works

• Listen — tap to start listening; BirdNET runs entirely in your browser via TensorFlow.js
• Identify — the model analyzes short audio clips and returns the most likely species
• Collect — every new species you hear is added to your local field journal
• Explore — browse your collection, see stats, and hunt for species you haven't found yet

No account needed. No audio ever leaves your device.

Tech stack

• SvelteKit — SPA framework (Svelte 5, runes mode)
• BirdNET + TensorFlow.js — on-device bird sound classification
• Browser APIs: Web Audio, IndexedDB, Geolocation
• Deno — runtime and package manager

Roadmap

• Bird listening and identification (BirdNET + TensorFlow.js)
