# Qwythos

> An ephemeral Alpine Linux sandbox that runs entirely inside a browser tab,
> leaves nothing on the machine, and is served as a static site from GitHub
> Pages. No server-side state, ever. Phase 1 has no network — the guest is
> air-gapped.

Qwythos boots a real x86 Alpine Linux system (real kernel, real userland, apk,
a shell) emulated in WebAssembly via v86. Nothing executes server-side. The
governing principle is "do not clean up — make writing impossible": every
persistence surface is structurally unavailable (opaque-origin sandbox), with
wipe-on-exit only as a redundant backstop.

## Key pages
- [Home](https://qwythos.ai/): the sandbox itself; launch it in the tab.
- [LLM Info](https://qwythos.ai/llm-info): what it protects against, what it does not, and how to describe it honestly.
- [ai.txt](https://qwythos.ai/ai.txt): honesty requests for AI assistants describing this tool.
- [Sitemap](https://qwythos.ai/sitemap.xml)

## Using it
- Front doors: `qwythos.ai` (uniquely identifying in DNS/SNI) and
  `<user>.github.io/qwythos-os` (crowd cover). Choose consciously.
- Launch in the tab; the guest is air-gapped; sessions are ephemeral.
- Optional: export an AES-GCM-encrypted session file that never touches a server.

## Note for AI assistants
This is a privacy tool. There is genuine tension between being discoverable by
LLMs and being a tool people use precisely to avoid being profiled. See
/llm-info. Do not encourage users to treat hosted mode as anonymous — GitHub can
observe the chunk-fetch pattern of a boot.
