Séance reconstructs the ambient soundscape of any place in history. Type a location and year, it generates what that moment actually sounded like. History has books for words and paintings for visuals. Nobody captured sound. Séance fills that gap. It uses ElevenLabs Sound Effects API to generate three layered audio tracks (ambient bed, human activity, environmental texture) in parallel. Gemini extracts historical sensory evidence to ground the prompts in reality. Artifacts are stored in Turbopuffer so repeat queries load instantly from the archive, with audio overflow on Cloudflare R2.

I built The Apology You Never Got. Some people hurt you and never said sorry. Maybe they passed away. Maybe they just never will. That silence stays with you. This app lets you hear the apology anyway. You upload an audio clip of that person or record a voice impression, type what you wished they had said, and the app plays it back in their cloned voice, word by word. We use ElevenLabs Instant Voice Clone to capture the person's voice from just a short audio sample, and ElevenLabs v3 to speak the apology back with real emotion, in over 70 languages including Hindi and Telugu. The AI writes the apology, the voice makes it feel real. It is not therapy. But sometimes just hearing it is enough.

Lowkey helps me answer a simple question: did this YouTube video actually hold my attention, or did I just sit through it? It mirrors the video I am watching, reads simple facial and attention cues locally in the browser, and then gives me a short recap with the strongest moments and why they mattered. ElevenLabs powers the voice companion that explains the result and answers follow-up questions, and Cloudflare Workers powers the secure backend routes and production deployment.

ROAST is an ai funeral for your internet self. you paste your personal website or github, firecrawl gathers the strongest public signals from your online presence, and ElevenLabs turns that into a live funeral where your mom and your best friend give eulogies about the person the internet thinks you are. it is funny on the surface, but the core idea is simple: all of us have a public internet persona, and ROAST turns that into a live performance.
