PostMortem lets you clone your voice and leave a sealed message for someone you love — to be opened on a specific date, or with a secret code only they know. When they open it, they don't read text. They hear you. ElevenLabs: Instant Voice Clone captures the user's voice from a 60-second recording. The cloned voice then speaks the written message via Multilingual TTS, preserving every nuance of tone and rhythm. An AI writing assistant (proxied through the Worker) helps users who don't know what to say. Cloudflare: Each vault is a Durable Object — a persistent, edge-native instance with its own SQLite database. The Alarms API schedules the exact unlock moment without polling or cron jobs: the vault literally wakes itself up when the time comes. Audio files are stored in R2 and streamed directly through the Worker, keeping API keys server-side. The frontend runs on Cloudflare Pages. What makes it different: this isn't a voice assistant or a productivity tool. It's a time capsule for the things that matter most — the message you'd want your daughter to hear on her wedding day, what you'd say to your best friend if you knew it was the last time. Voice is the most human thing we have. PostMortem preserves it.
