Automated security scan — not a certification.
I started Wenlan because my notes, documents, and AI chats were scattered, and keeping a note system from rotting took constant upkeep. Since then we keep hearing the same about Obsidian: too much setup, with plugins to find, install, and keep updated. Wenlan is for people who use AI tools every day and don't want to maintain a note system.
Personal: download the desktop app and use it on your own.
Teams (in the next release): a self-hosted Wenlan server everyone connects to, with view-only or edit access for each person.
| Obsidian + plugins | Notion | LLM wiki apps | Wenlan | |
|---|---|---|---|---|
| Who organizes | You, with plugins | You, or Notion's agents | An AI you set up | Your AI tools; updates when a source changes |
| Setup | Find and update plugins | Full AI on the Business plan | Model key or scheduled routine | One click, no API key |
| Checks the AI's work | Depends on the plugin | Cites sources; no match check | Links to sources | Refuses pages whose citations don't match |
| What AI may change | Depends on the plugin | Pages you give an agent | Its wiki folder | You choose per page; restore anytime |
| Where notes live | Your computer | Notion's cloud | Your computer | Your computer; works with your vault |
Download the desktop app for macOS 11 or later on Apple Silicon, Windows x64, or Linux x64 (AppImage or .deb, from v0.22). The app is in English, 简体中文, and 繁體中文.
Prefer the terminal? On a Mac, run npx -y wenlan setup, or brew install 7xuanlu/tap/wenlan and then wenlan setup. Linux and Windows: CLI install guide.
Create a page, or bring in an Obsidian vault, a Logseq graph, a folder, or earlier AI chats. Import guide.
In the App's Settings, Add a tool finds the AI tools on your computer and Connect all sets them up in one press. There is nothing else to install or keep updated. Then start a new AI session and ask:
/wenlan what did I decide about this before? Then help me: …
/wenlan ($wenlan in Codex) is the one command to remember: say what you want after it.
Works with Claude Code, Claude Desktop, Codex, Cursor, GitHub Copilot, VS Code, Gemini CLI, Windsurf, Grok Bot, and other MCP tools. Set one up by hand.
When an import finishes, the app offers Write pages with your AI tool to turn it into your first cited pages. No command needed.
/wenlan wiki writes pages tied to the code. Code wiki.You can also connect an Open Knowledge Format (OKF) folder as a source. Scanned PDFs need text extraction first; chat attachments are not imported. Import guide.
Your AI tool reads what you bring in and writes it into Markdown pages. It links related pages, cites where each sentence came from, and brings pages up to date when a source changes. You can open any page and write in it yourself.
[n], Wenlan compares each cited sentence with its source and refuses the page when most citations don't match. Passing the check does not prove a page correct.[[links]] that point to no page yet./wenlan and say what you want: look up earlier decisions, save a lesson, or pick up where you stopped. Shortcuts: /recall, /capture, /handoff, /brief. Plugin commands.
