What this page covers
Two tools appear here. KnowMan saves articles and links and answers questions with citations. The rest of this page describes what each one does.
Save the explainers you trust
KnowMan saves articles and links and reads and tags them. The browser extension works in Chrome and is listed on the Chrome Web Store. A saved library can hold hospital patient pages, guideline summaries, and long explainers on a condition. If your reading already lives elsewhere, KnowMan imports from Pocket, Instapaper, Omnivore, Readwise, Wallabag, and a browser bookmarks file. For a wider view, see what a personal knowledge base is good for.
Search your health reading by meaning
KnowMan lets you search saved items by keyword or meaning, so a search like 'what did that article say about ferritin' can find the page. KnowMan also answers questions with citations. The Free plan includes five Ask questions a day. See how an AI knowledge base works.
Keep memories alongside your reading
KnowMan keeps memories alongside your reading, saved as claims, decisions, and playbooks. The kb_memories tool lists them over MCP, and the CLI command knowman memories lists them in the terminal. A conclusion you save stays in the library after the browser tab is closed.
Keep a plain record of your lab results
You can scan or import a lab report as a PDF, photo, or camera capture, and AI extracts each test with its value, unit, and reference range. You can watch values such as cholesterol, vitamin D, or thyroid trend across years. A built-in AI assistant explains what a marker means in plain language, and it always reminds you that your doctor has the final word. LabDrive also has an AI health chat that explains and never diagnoses. All health data stays on your device, in an encrypted database on your phone rather than the app maker's servers. A Face ID or passcode lock is built in, and AI features are strictly opt-in.
Let an AI agent search your library
KnowMan also runs an MCP server, so an AI agent you already chat with can work over your saved reading. The server is open source, MIT licensed, runs locally over stdio with npx -y @knowman/mcp on Node 22 or newer, and is also available as a hosted remote server at api.knowman.io/mcp with OAuth sign-in or an API key. It exposes six tools: kb_search, kb_ask, kb_get_item, kb_save, kb_recent, and kb_memories. The hosted server is verified with the official MCP SDK client. Start with an MCP server knowledge base guide or give your AI context.
What each tool covers
KnowMan saves articles and links, searches saved items by keyword or meaning, answers questions with citations, and keeps memories of claims, decisions, and playbooks. LabDrive turns every lab report into structured, trackable data, and all health data stays on your device.
Questions people ask
Can KnowMan answer health questions from what I saved?
Yes, from your own library. KnowMan answers questions with citations drawn from the items you saved, and the Free plan includes five Ask questions a day. See the personal knowledge base guide.

Where does LabDrive keep my health data?
On your device. Health data lives in an encrypted database on your phone, never on the app maker's servers. A Face ID or passcode lock is built in, and AI features are strictly opt-in.
Does LabDrive's AI health chat diagnose?
No. The AI health chat explains and never diagnoses. The built-in AI assistant always reminds you that your doctor has the final word.
