What is Sadie
Sadie is a personal wiki and a proactive briefing engine. It reads your sources, keeps a compounding wiki of what you know, maintains a working model of how you think (the Soul), watches live discourse, and surfaces a few timely angles worth saying. One user per deployment. SaaS by default, self-hostable if you want to own the data.
Sadie is not a chat wrapper and it is not a search engine. Everything compounds on the same data. The wiki you build today makes tomorrow’s briefing sharper. The rewrites you accept today teach Sadie your voice. The discourse you dismiss today narrows what it surfaces tomorrow.
What it does differently
Section titled “What it does differently”Most AI tools ask you to fill out a profile and then try to be clever. Sadie does the opposite. It watches behavior. Which sources you weight. Which angles you rewrite. Which drafts you file. Which briefs you dismiss. These signals, not a self-description, are how Sadie learns who you are.
Three ideas carry the product:
- Behavioral inference over self-description. You are not asked “what is your voice”. Sadie distills it from what you actually write and what you actually choose.
- A compounding wiki. Every source, brief, and conversation can touch the wiki. Entries version, cite their evidence, and lint themselves for staleness, weak provenance, and contradictions.
- Discourse opportunities. Today shows at most three high-conviction cards. Each explains why the topic is live now, why you are positioned for it, who is already talking, and three to five candidate angles you could plausibly say.
The surfaces

- Memory for wiki, briefs, sources, Soul, and the graph
- Feeds for live signal monitoring
- Access for Studio collaborator roles
- Settings for persona, cadence, AI provider, and the self-evolution version history
