Single Access Memory

An ephemeral journaling app where you write in Markdown and entries auto-delete after being read once. Perfect for people who want to share thoughts publicly without permanent records, like temporary confessions or mood journaling.

Ephemeral content has proven demand — Snapchat built a billion-dollar business on it, and the post-pandemic mental health wave has normalized public vulnerability in ways that create real appetite for low-stakes emotional expression. The closest substitute is a combination of tools: Notion for Markdown writing plus manual deletion, or anonymous platforms like Whisper, but nothing purpose-built for read-once journaling exists at any meaningful scale, so there's no clear incumbent to fight directly. At $200–1k/month, this is lifestyle revenue at best, which is fine only if infrastructure costs stay near zero — ephemeral storage is cheap, but abuse prevention, moderation exposure, and the inevitable edge cases around screenshots defeating the whole premise will cost real engineering time. The biggest risk is that the read-once mechanic sounds clever but solves a problem people work around in thirty seconds with a screenshot, which means the core value proposition collapses the moment a user thinks about it for more than a minute.
