I built an offline wiki that fits in a single 19 KB HTML file

I kept hitting the same wall looking for an offline wiki. Kiwix is great, but it's an app plus multi-GB ZIM files. IPFS needs connectivity and setup. I just wanted something dead simple: a knowledge file you can open on any phone with no install, and hand to the next person over Bluetooth or a USB stick.

So I built Portable Knowledge Mesh. It's one reader.html (~19 KB). You open it — even straight from file:// — load a .mesh pack, and read/search offline. To share it, you just send the file; the other person opens it in any browser. The whole thing — reader plus a 21-article survival pack — is under 50 KB. It fits in a single chat message.

A Wikipedia that spreads via Bluetooth, USB, and AirDrop — no server, no install, no internet required.

What is this?

Portable Knowledge Mesh is a single HTML file that turns any phone or laptop into an offline wiki. It opens in a browser — even straight from a USB stick, an email attachment, or a Bluetooth share — and lets you read, search, and pass on curated knowledge without ever touching a server.
