PlainTXT
Private encrypted messages, burn after reading, ephemeral
What it does
plaintxt is a no-account, end-to-end encrypted messaging app for temporary conversations. Create a browser-local identity, send encrypted messages, and walk away. No email, no phone number, no password, no tracking, and no ads. Messages are encrypted in your browser before they leave your device. The server stores ciphertext only. Unread messages expire automatically, and read messages burn shortly after being opened. Built for conversations that do not need to live forever.

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
