Sigillion

Remember everything. Read almost nothing. Prove all of it.

Sigillion is memory for AI agents, made by Steddy Nova SRL. It keeps the whole record of what an agent and a person did,
word for word, on your own computer; compressed, so that a model can skim weeks of work in a few hundred tokens and open
the full text only where it needs it; sealed, so that every record can be checked to show it was not altered. No
telemetry: nothing leaves your computer.

One engine, in order

1. Claude Code first. Today Sigillion ships as a Claude Code plugin: every session is kept after compaction and after
   Claude Code deletes its transcripts, and Claude searches and reopens its own history while it works. Claude Code is
   where every feature is built, measured and proved on real work. It is the first step, not the whole idea.
2. Every AI model and agent tool next. The engine does not depend on one model. The same sealed memory will sit under
   other models and the tools people already use (coding agents, agent frameworks, assistants), with an SDK for anyone
   who builds agents.
3. Then the fields where the record must stand: legal and finance. The same store, with a pack for each field: its
   citations and terms, its redaction rules, and receipts that show what the model did and when, for work a client, a
   regulator or a court may ask about.

Each step comes after the one before has proved itself with other people's numbers, not before.

The launch

• Sigillion is being prepared for release on PyPI, for Windows and Linux (macOS later). It will need Claude Code
  2.1.287 or later and Python 3.10 or later.
• The first 500 users get a founder licence: Pro for one person, free for life.
• How it ships: the engine compiled; the storage format and the capture (what touches your transcripts) as readable
  source. Sigillion is not open source: all rights are reserved by Steddy Nova SRL.
• Recording is free for good; reading sessions back needs a licence after a 30-day trial.

Issues are public: do not write e-mail addresses, client names, code or anything private.

Rather not sign up in public? Write to [email protected] with your GitHub username: you join the same list.

If you want, tick that you'd share Sigillion's results: once a week you paste the counts Sigillion prints about what it
did for you (how many answers came from memory, how much of your history they read, and the like). Numbers only,
never the text of your sessions, and only what you choose to paste. It helps us show what Sigillion does.

At the launch

• The one-command install comes with the release, for Windows and Linux. The waitlist gets it first.
• The 500 founder licences go to the list in the order people joined (spam and duplicates removed).
• We reply on your issue, so GitHub notifies you; if you wrote to us, we answer by e-mail.
• Your licence is sent to you privately, never posted in an issue.
• To hear about the release too: Watch this repository > Custom > Releases.

If you write to us, we use your address only to answer you and to send your licence, and delete it when you ask.

No code here yet. This repository is the list; there is no public install yet.
