Show HN: Fantasy Football Neuron – AI-powered debates for lineup building (fantasyfootballneuron.app)
1 points by machinemusic 342 days ago
I built an app called Fantasy Football Neuron, a tool that turns fantasy football lineup research into live multi-agent debates.

Instead of static articles or black-box optimizers, you pick a panel of up to six AI analysts (tuned on different strategies: GPP, data-heavy, contrarian, etc.). Ask a question like “Tua or Allen?” → they argue it out in real-time with ElevenLabs voices. The transcript shows why each pick wins, and you can export the chosen lineup directly to DraftKings/FanDuel.

Tech stack: • Backend: Cloud Run + Cloud Functions (serverless-first) • Frontend: Next.js (hosted via Lovable) • Database: Firestore (real-time debate/live dashboard) • Caching: Redis + Cloudflare edge routing (infra <$0.05 per debate) • Models: six LoRA adapters trained on open-source LLMs (Vertex AI preemptible GPUs) • TTS: ElevenLabs for character voices

Live here: https://fantasyfootballneuron.app

Would love feedback from the HN community on the approach — especially around scaling real-time debates and caching optimizations.

This started as an experiment in game theory and cognitive architectures. I wanted to see if lineup optimization could be turned into a conversation instead of spreadsheets or opaque optimizers.

Closed beta (32 users) gave me feedback that shaped the “One-Click Pivot” feature and real-time lineup exports. It’s now live for NFL pre-season.

Not perfect yet (still optimizing infra + analyst creation UX), but I figured it’s better to share early and get feedback from builders here.
