llmwiki

llmwiki

LLM-powered knowledge base from your Claude Code, Codex CLI, Cursor, Gemini CLI, and Obsidian sessions. Built on Andrej Karpathy's LLM Wiki pattern.

👉 Live demo: pratiyush.github.io/llm-wiki

Rebuilt on every master push from the synthetic sessions in examples/demo-sessions/. No personal data. Shows every feature of the real tool (activity heatmap, tool charts, token usage, model info cards, vs-comparisons, project topics) running against safe reference data.

Every Claude Code, Codex CLI, Copilot, Cursor, and Gemini CLI session writes a full transcript to disk. You already have hundreds of them and never look at them again.

llmwiki turns that dormant history into a beautiful, searchable, interlinked knowledge base — locally, in two commands. Plus, it produces AI-consumable exports (llms.txt, llms-full.txt, JSON-LD graph, per-page .txt + .json siblings) so other AI agents can query your wiki directly.

./setup.sh                         # one-time install
./build.sh && ./serve.sh           # build + serve at http://127.0.0.1:8765

Want LLM-enriched wiki pages from the CLI? After ./setup.sh, llmwiki sync only fills raw/. To populate wiki/sources/ (semantic summaries), set synthesis.backend in examples/sessions_config.json (ollama for local Ollama, or keep dummy for stubs), then run llmwiki synthesize or chain it with llmwiki all --with-synth. See docs/modes/api/ and llmwiki sync --status for the current backend hint.

llmwiki sync
llmwiki all --with-synth --graph-engine builtin   # synthesize → build → graph → export → lint

Image: llmwiki — 70-second demo

Contributing in one line: read CONTRIBUTING.md, keep PRs focused (one concern each), use feat: / fix: / docs: / chore: / test: commit prefixes, never commit real session data (raw/ is gitignored), no new runtime deps. CI must be green to merge.

Screenshots

All screenshots below are from the public demo site which is built on every master push from the dummy example sessions. Your own wiki will look identical — just with your real work.

Home — projects overview with activity heatmap

Image: llmwiki home page — LLM Wiki header, activity heatmap, and a grid of three demo projects (demo-blog-engine, demo-ml-pipeline, demo-todo-api)

All sessions — filterable table across every project

Image: llmwiki sessions index — activity timeline above a table of eight demo sessions with project, model, date, message count, and tool-call columns

Session detail — full conversation + tool calls

Image: llmwiki session detail — Rust blog engine scaffolding session showing summary, breadcrumbs, a TOML Cargo.toml block and a Rust main.rs block, both highlighted by highlight.js

Changelog — renders CHANGELOG.md as a first-class page

Image: llmwiki changelog page — keep-a-changelog format with colored headings for Added / Fixed / Changed and auto-linked PR references

Projects index — freshness badges + per-project stats

Image: llmwiki projects index — three demo project cards with green/yellow/red freshness badges showing how recently each project was touched

What you get

Human-readable

• All your sessions, converted from .jsonl to clean, redacted markdown

• A Karpathy-style wiki — sources/, entities/, concepts/, syntheses/, comparisons/, questions/ linked with [[wikilinks]]

• A beautiful static site you can browse locally or deploy to GitHub Pages

  • Global search (Cmd+K command palette with fuzzy match over pre-built index)

  • highlight.js client-side syntax highlighting (light + dark themes)

  • Dark mode (system-aware + manual toggle with data-theme)

  • Keyboard shortcuts: / search · g h/p/s nav · j/k rows · ? help

  • Collapsible tool-result sections (auto-expand > 500 chars)

  • Copy-as-markdown + copy-code buttons

  • Breadcrumbs + reading progress bar

  • Filter bar on sessions table (project/model/date/text)

  • Reading time estimates (X min read)

  • Related pages panel at the bottom of every session

  • Activity heatmap on the home page

  • Model info cards with structured schema (provider, pricing, benchmarks)

  • Auto-generated vs-comparison pages between AI models

  • Append-only changelog timeline with pricing sparkline

  • Project topic chips (GitHub-style tags on project cards)

  • Agent labels (colored badges: Claude/Codex/Copilot/Cursor/Gemini)

  • Recently-updated card on the home page

  • Dataview-style structured queries in the command palette

  • Hover-to-preview wikilinks

  • Deep-link icons next to every heading

  • Mobile-responsive + print-friendly

AI-consumable (v0.4)

Every HTML page has sibling machine-readable files at the same URL:

• <page>.html — human HTML with schema.org microdata

• <page>.txt — plain text version (no HTML tags)

• <page>.json — structured metadata + body

Site-level AI-agent entry points:

Every page also includes an <!-- llmwiki:metadata --> HTML comment that AI agents can parse without fetching the separate .json sibling.

Recipe — query graph.jsonld from your terminal

The JSON-LD graph isn't just for crawlers — you can ask quick questions about your wiki without leaving the shell. Example: print every session as a tree, grouped by project:

python3 examples/scripts/tree_from_graph.py

Output:

📚 8 sessions across 3 projects
   (site/graph.jsonld v1.3.0)

llmwiki/
├── demo-blog-engine/  (4 sessions)
│   ├── 2026-03-12  scaffolding-the-rust-blog-engine
│   ├── 2026-03-18  adding-syntax-highlighting
│   ├── 2026-03-25  rss-feed-and-sitemap
│   └── 2026-04-01  dark-mode-toggle
├── demo-ml-pipeline/  (2 sessions)
│   ├── 2026-01-20  training-data-pipeline

└── demo-todo-api/  (2 sessions)
    ├── 2026-02-08  fastapi-project-bootstrap
    └── 2026-02-15  adding-oauth-login

The full script is stdlib-only at examples/scripts/tree_from_graph.py. Same recipe pattern works for any aggregation question — count sessions per model, find the largest project by token usage, list every entity that appears in 3+ sessions, etc. The graph is yours to slice.

Quality & governance (v1.0)

• 4-factor confidence scoring — source count, source quality, recency, cross-references; with Ebbinghaus-inspired decay per content-type

• 5-state lifecycle machine — draft → reviewed → verified → stale → archived with 90-day auto-stale

• 16 lint rules — 8 structural (frontmatter, link integrity, orphans, freshness, duplicates, index sync…) + 3 LLM-powered (contradictions, claim verification, summary accuracy) + stale_candidates (#51) + tags_topics_convention (#302) + stale_reference_detection (#303) + frontmatter_count_consistency (#378) + tools_consistency (#378)

• Auto Dream — MEMORY.md consolidation after 24h + 5 sessions: resolve relative dates, prune outdated, 200-line cap

• 9 navigation files — CLAUDE.md, AGENTS.md, MEMORY.md, SOUL.md, CRITICAL_FACTS.md, hints.md, hot.md + per-project hot caches

Obsidian-native experience (v1.0)

• link-obsidian CLI — symlinks the whole project into an Obsidian vault; graph view + backlinks + full-text search just work

• Dataview dashboard — 10 ready-to-use queries (recently updated, by confidence, by lifecycle, by project, by entity type, open questions, stale pages)

• Templater templates — 4 templates for source/entity/concept/synthesis pages, seeded with confidence + lifecycle + today's date

• Category pages — tag-based index pages in both Dataview (Obsidian) and static markdown (HTML) modes

• Integration guide — docs/obsidian-integration.md covers 6 recommended plugins with per-plugin configs

Automation

• SessionStart hook — auto-syncs new sessions in the background on every Claude Code launch

• Auto-build on sync — /wiki-sync triggers /wiki-build (configurable; default on)

• One-shot pipeline — llmwiki all runs build → graph → export → lint in a single command (--strict for CI)

• MCP server — 12 production tools (query, search, list, read, lint, sync, export, + confidence, lifecycle, dashboard, entity search, category browse) queryable from any MCP client (Claude Desktop, Cline, Cursor, ChatGPT desktop)

• Pending ingest queue — SessionStart hook converts + queues; /wiki-sync processes queue

• No servers, no database, no npm — Python stdlib + markdown. Syntax highlighting loads from a highlight.js CDN at view time.

Tutorial — every command in 90 seconds

A guided tour. Run these in order and you'll have a fully working wiki at http://127.0.0.1:8765/ by the end. Each command is idempotent and prints what it did.

A scripted recording of the same flow ships at docs/videos/cli-tutorial.gif (31 seconds against an 8-session sandbox). The reproducible source is docs/videos/cli-tutorial.tape — re-render anytime with vhs docs/videos/cli-tutorial.tape.

# 1. One-time scaffold (≈1 sec). Creates raw/, wiki/, site/, seed nav files.
llmwiki init

# 2. Pull in your sessions (≈1 sec / 100 sessions). Walks every adapter
#    that's "available" on this machine (Claude Code, Codex CLI, Cursor,
#    Gemini, Obsidian, Copilot Chat / CLI), converts new .jsonl files to
#    raw/sessions/*.md, then runs build + lint by default.
llmwiki sync

# 3. Compile the static HTML site (≈3 sec on a 500-session corpus).
#    Already runs as part of `sync`; call directly when you're iterating
#    on a wiki/ page and don't need a fresh sync.
llmwiki build

# 4. Browse it locally. Cmd+K opens the search palette; / focuses the
#    filter bar on /sessions/. Press Ctrl+C to stop.
llmwiki serve

# 5. (Optional) Generate the knowledge graph + AI-consumable exports.
#    `all` runs build → graph → export → lint in one shot.
llmwiki graph
llmwiki export all
llmwiki all     # one-shot equivalent of build + graph + export + lint

That's the entire happy path. Two more commands you'll reach for occasionally:

# Inspect what's installed + configured. Prints a per-adapter table:
# (available: yes/no, configured: yes/no, session-store path).
llmwiki adapters

# Lint the wiki. 16 rules — broken wikilinks, orphaned pages, stale
# summaries, duplicate detection, freshness, missing entities, etc.
# Runs as part of `sync` by default; call directly for a one-shot check.
llmwiki lint

Three optional flags you'll discover later:

• --adapter <name> — limit sync to one adapter (e.g. --adapter claude_code)

• --vault PATH — write into an Obsidian / Logseq vault overlay instead of wiki/ (#54)

• --synthesize — call out to a local Claude / Ollama backend during build for an LLM-generated overview page

Each subcommand has its own --help with the rest. The CLI reference table below is the full list.

Documentation

Full production documentation lives under docs/. The editorial hub is docs/index.md — tutorials, per-agent guides, reference, and deployment, all in one place.

Start here:

Contributing to docs? See the style guide.

Install

macOS / Linux

git clone https://github.com/Pratiyush/llm-wiki.git
cd llm-wiki
./setup.sh

Windows

git clone https://github.com/Pratiyush/llm-wiki.git
cd llm-wiki
setup.bat

With pip (v0.3+)

pip install -e .                # basic — everything you need
pip install -e '.[graph]'       # + graphifyy AI-powered graph engine
pip install -e '.[dev]'         # + pytest + ruff
pip install -e '.[e2e]'         # + Playwright + pytest-bdd + pytest-html (E2E)
pip install -e '.[all]'         # graph + everything

Syntax highlighting is now powered by highlight.js, loaded from a CDN at view time — no optional deps required.

What setup does

1. Creates raw/, wiki/, site/ data directories

2. Installs the llmwiki Python package in-place

3. Detects your coding agents and enables matching adapters

4. Optionally offers to install the SessionStart hook into ~/.claude/settings.json for auto-sync

5. Runs a first sync so you see output immediately

For maintainers

Running the project? The governance scaffold lives under docs/maintainers/ and is loaded by a dedicated skill:

Four Claude Code slash commands automate the common ops:

• /review-pr <N> — apply the REVIEW_CHECKLIST to a PR and post findings

• /triage-issue <N> — label + milestone + priority a new issue

• /release <version> — walk the release process step by step

• /maintainer — meta-skill that loads every governance doc as context

Running E2E tests

The unit suite (pytest tests/ — 2,651 tests) runs in seconds and covers every module. The end-to-end suite under tests/e2e/ is separate: it builds a minimal demo site, serves it on a random port, drives a real browser via Playwright, and runs scenarios written in Gherkin via pytest-bdd.

Why both? Unit tests lock the contract at the module boundary; E2E locks the contract at the user's browser. A diff that passes unit tests but breaks the Cmd+K palette will fail E2E.

Install the extras (one-time, several hundred MB for the Chromium binary):

pip install -e '.[e2e]'
python -m playwright install chromium

Run the suite:

pytest tests/e2e/ --browser=chromium

Run a single feature:

pytest tests/e2e/test_command_palette.py --browser=chromium -v

The E2E suite is excluded from the default pytest tests/ run (see the --ignore=tests/e2e addopt in pyproject.toml) so you can iterate on the unit suite without waiting for browser installs. CI runs the E2E job as a separate workflow (.github/workflows/e2e.yml) that only fires on PRs touching build.py, the viz modules, or tests/e2e/**.

Feature files live under tests/e2e/features/ — one per UI area (homepage, session page, command palette, keyboard nav, mobile nav, theme toggle, copy-as-markdown, responsive breakpoints, edge cases, accessibility, visual regression). Step definitions are all in tests/e2e/steps/ui_steps.py. Adding a new scenario is usually a 2-line change to a .feature file plus maybe one new step.

Run locally with an HTML report:

pytest tests/e2e/ --browser=chromium \
  --html=e2e-report/index.html --self-contained-html
open e2e-report/index.html     # macOS — opens the browseable report

Where to see test reports:

Locally, the HTML report is one file (e2e-report/index.html) that you can open in any browser — pass/fail per scenario, duration, stdout/stderr, screenshot on failure.

Scheduled sync

For a daily / weekly cron-style sync, schedule llmwiki sync directly via your OS's native job runner (launchd on macOS, systemd on Linux, Task Scheduler on Windows). Paths and adapter selection come from examples/sessions_config.json.

CLI reference

llmwiki init                    # scaffold raw/ wiki/ site/ + seed nav files
llmwiki sync                    # convert .jsonl → markdown (auto-build + auto-lint if configured)
llmwiki build                   # compile static HTML + AI exports
llmwiki serve                   # local HTTP server on 127.0.0.1:8765
llmwiki adapters                # list available adapters + configured state (v1.0)
llmwiki graph                   # build knowledge graph (v0.2)
llmwiki lint                    # 16-rule wiki lint (v1.2)
llmwiki export <format>         # AI-consumable exports (v0.4)
llmwiki synthesize              # auto-ingest synthesis pipeline (v0.5)
llmwiki all                     # build → graph → export → lint in one shot (v1.2)
llmwiki version

Each subcommand has its own --help. All commands are also wrapped in one-click shell/batch scripts: sync.sh/.bat, build.sh/.bat, serve.sh/.bat, upgrade.sh/.bat.

Works with

Adding a new agent is one small file — subclass BaseAdapter, declare SUPPORTED_SCHEMA_VERSIONS, ship a fixture + snapshot test.

MCP server

llmwiki ships its own MCP server (stdio transport, no SDK dependency) so any MCP client can query your wiki directly.

python3 -m llmwiki.mcp   # runs on stdin/stdout

Twelve production tools (7 core + 5 added in v1.0 #159):

Register in your MCP client's config — e.g. for Claude Desktop, add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "llmwiki": {
      "command": "python3",
      "args": ["-m", "llmwiki.mcp"]
    }
  }
}

Configuration

Single JSON config at examples/sessions_config.json. Copy to config.json and edit:

{
  "filters": {
    "live_session_minutes": 60,
    "exclude_projects": []
  },
  "redaction": {
    "real_username": "YOUR_USERNAME",
    "replacement_username": "USER",
    "extra_patterns": [
      "(?i)(api[_-]?key|secret|token|bearer|password)...",
      "sk-[A-Za-z0-9]{20,}"
    ]
  },
  "truncation": {
    "tool_result_chars": 500,
    "bash_stdout_lines": 5
  },
  "adapters": {
    "obsidian": {
      "vault_paths": ["~/Documents/Obsidian Vault"]
    }
  }
}

All paths, regexes, truncation limits, and per-adapter settings are tunable. See docs/configuration.md.

.llmwikiignore

Gitignore-style pattern file at the repo root. Skip entire projects, dates, or specific sessions without touching config:

# Skip a whole project
confidential-client/
# Skip anything before a date
*2025-*
# Keep exception
!confidential-client/public-*

Karpathy's LLM Wiki pattern

This project follows the three-layer structure described in Karpathy's gist:

1. Raw sources (raw/) — immutable. Session transcripts converted from .jsonl.

2. The wiki (wiki/) — LLM-generated. One page per entity, concept, source. Interlinked via [[wikilinks]].

3. The schema (CLAUDE.md, AGENTS.md) — tells your agent how to ingest and query.

See docs/architecture.md for the full breakdown and how it maps to the file tree.

Design principles

• Stdlib first — only mandatory runtime dep is markdown. Optional extras (graph, dev, e2e) layer in graph engines, lint/test tooling, and Playwright on top.

• Works offline — no Google fonts, no external CSS. Syntax highlighting loads from a highlight.js CDN but degrades gracefully without it.

• Redact by default — username, API keys, tokens, emails all get redacted before entering the wiki.

• Idempotent everything — re-running any command is safe and cheap.

• Agent-agnostic core — the converter doesn't know which agent produced the .jsonl; adapters translate.

• Privacy by default — localhost-only binding, no telemetry, no cloud calls.

• Dual-format output (v0.4) — every page ships both for humans (HTML) and AI agents (TXT + JSON + JSON-LD + sitemap + llms.txt).
