Decast: GenAI Live Casting

Don't just stream it, cast it live. AI auto-publishing with tamper-proof, decentralized recording.

The problem

Streaming is transient: once a live session ends, the content and its proof of authenticity are gone, and creators spend hours turning streams into posts. Decast makes casting intentional, recorded, owned, and automatically repurposed.

What I built

Live casting with an AI auto-publishing workflow: transcribe, summarize, generate posts, publish everywhere
Tamper-proof Web3 recording with cryptographic signatures, stored on IPFS
Multi-platform content distribution from a single cast
Node.js backend and Next.js front end, with OpenAI powering the generative layer

Outcome

Every cast is recorded, owned, and verifiable
Content is auto-repurposed and published across platforms
Serves journalists, podcasters, legal teams, and Web3 communities
