// Two apps, equal billing

One writes. One reads.

They share a network and a design, nothing else. etchit — the Etch Writer — puts things on Autonomi; fetchit — the Fetch Browser — takes them off. Use either, both, or neither — the address works from any client on the network.

etch/it
Etch it once.
Fetch it forever.

Save text to Autonomi and share it with a single permanent address. Connect your own wallet, pay a small one-time fee to the storage peers, and what you etched stays reachable as long as the network runs — public, or private behind biometric auth on your device.

  • Text, notes, code, long-form — anything that fits as text
  • Public or private etches; private keys stay in the Android Keystore
  • Encrypted backups, restorable on any device with a 6-word passphrase
  • Non-custodial · pay once, no subscription

fetch>it
Paste an address.
See what's there.

A read-only browser for the network. Paste any Autonomi address and fetchit fetches it by content hash and renders it — text, PDFs, images, audio, video, even full HTML pages with working scripts. No wallet, no account: fetching is always free. A reader, not a host — what it pulls is cached privately on your device, like a browser cache.

  • Auto-detects what an address holds and renders it inline
  • HTML pages run with real web APIs — fetch, WebAssembly, media
  • Files download whole, then play / open / save — cached for offline
  • Free to read · open source · Android

// What's underneath

Built like infrastructure, not a service.

Neither app has a server. Both are thin clients over the public Autonomi network — addresses are derived from content with BLAKE3, payments settle on Arbitrum One, and the binaries are reproducible from the source you can read.

01
reach
Pay once to write. Stored as long as the network runs. No renewals, no expiry.
02
0accts
No signups, no email, no password. A wallet to write; nothing at all to read.
03
0custody
No etchit server, no etchit database. The apps never hold your data or keys.
04
B3addr
Addresses are content hashes — what you fetch is byte-for-byte what was written, or it doesn't resolve.
05
Rbuild
Reproducible builds. The APK we ship is verifiable against the code in-tree.
06
OSS
Both apps and the shared native networking core are fully open source.
// Running on the network, right now

A website with no website.

demo-city is a small site that lives entirely on Autonomi — no DNS, no host, no origin server. Open this address in fetchit and you get a real, multi-page site with seven destinations: a reading room, a photo gallery, an album, a cinema, a code lab, an essay, and a game — every page, image, track and WebAssembly module fetched by content hash.

Paste it into fetch>it on Android. There's no link to click here — that's the point: the address is the site.

Etch it.
Fetch it.

Both apps are open source and free to read. No waitlist, no email capture — pick one, or grab both.
