A personal Wikipedia an LLM maintains for you.

Drop in articles, papers, notes, PDFs, or URLs. An agent reads them and writes a cross-linked markdown wiki you fully own. Knowledge compounds — each new source makes every page richer, not just one new page longer.

npm install -g @syasas/llm-wiki

What it actually does

Three operations. One folder of markdown.

Ingest

Drop a source (text / PDF / URL / image). The LLM reads it alongside your existing wiki, writes new pages, updates older pages where context shifts, refreshes the index, logs the change. Each ingest is a refactor pass — not an append.

Query

One-shot Q&A against the whole wiki with cited pages. 'Save as wiki page' promotes useful answers into permanent entries. For ongoing back-and-forth, use Chats — saved as plain markdown files.

Lint

Two-pass health check: local scan for broken links + orphans, then an LLM pass for contradictions, gaps, stale claims. Every issue ships with one-click fixes, including LLM-powered ones that write the page edit for you.

Why this exists

The gap between chat and notes.

RAG chat (NotebookLM, ChatGPT files)

Stateless. Rediscovers your corpus on every query. Nothing accumulates that you can read later.

Note-taking apps (Obsidian, Notion)

All the maintenance burden on you. You write, you cross-link, you check for contradictions. Nothing scales.

LLM Wiki

Sits between them. The LLM does the maintenance. The wiki accumulates value. You own the markdown files.

After a few weeks of feeding it sources, you have a navigable, cited, deliberately-organized body of knowledge about whatever you care about — without ever having written a page yourself.

Coming soon

Use it without installing.

The hosted version — sign in, click a button, start ingesting. Same engine as the open-source CLI, same markdown wiki underneath. We handle the server, you focus on the knowledge. Drop your email to hear when it's ready.

No spam. One email when the hosted version is ready.

In the meantime: the open-source CLI is fully usable today — npm install -g @syasas/llm-wiki.
