sigil.bot

A zero-install, message-native provenance layer.

What it is

DM the bot. Get back a cryptographically signed, Bitcoin-anchored timestamp that survives even if Sigil itself shuts down.

It makes downstream ghost-authorship demonstrably provable.

How it works

You DM the bot with the content you want to anchor.
You receive a signed receipt: a hash of the content, a timestamp, and a CC-BY attribution license, signed by Sigil.
The receipt is committed to the Bitcoin blockchain.
Anyone can verify the receipt against the chain — no Sigil server required.

Who this is for

Anyone whose words travel through chats before they reach a page or a platform: writers, artists, researchers, organizers, builders, creators of any kind whose work circulates in conversation before it ships.

Especially the voices most often extracted from without recognition — unhoused contributors, grassroots storytellers, people whose lived experience shapes policy, research, and reporting they are rarely cited in.

What it doesn’t do

Sigil proves origin. It doesn’t restrict use.

It doesn’t prevent copying.
It doesn’t detect paraphrase or AI rewriting.
It isn’t private storage. Receipts are public by design.

Only anchor what you are willing to publish.

Why

A concrete example of Transmutarian anti-extractive infrastructure: tools that work without locking you in, prove without trusting the prover, and outlive the operator.

Built to support cognitive sovereignty.
