Getting Started
What is Markcat?
Markcat is an AI-powered bookmark manager that automatically classifies your bookmarks into a hierarchical category tree. Save a link, and Markcat fetches the page, reads the content, and sorts it into the right category — no manual tagging needed.
How It Works
- Save a bookmark (via extension, web app, or API).
- Fetch — Markcat downloads the page content: plain HTTP first, then a real browser for JS-heavy sites, then browser stealth mode for bot-protected sites.
- Classify — an LLM summarizes the content, then assigns a category path (e.g.
Tech / Programming / Python). - Browse — your bookmarks appear in a navigable category tree.
Installation
Option 1: Chrome Extension + Local Service (User A)
This runs entirely on your machine. No account needed. The source code will be available at public launch.
Requirements: Python 3.11+, Chrome/Chromium.
# From the project root
pip install -r service/requirements.txt
# Start the service
python -m service.main
# → http://127.0.0.1:8080
Then install the Chrome extension:
- Open
chrome://extensions - Enable “Developer mode”
- Click “Load unpacked” → select the
markcat-extension/folder
Option 2: Markcat Web App (User D)
Visit markcat.app, create an account, and start saving bookmarks. No local setup or API keys needed — classification runs on the hosted service.
Option 3: Self-Hosted Cloud (User B/C)
See self-hosting.md for PostgreSQL setup and deployment.
First Run
Web app (hosted): register at markcat.app and save your first link — it is fetched and classified automatically, nothing to configure.
Chrome extension: on first install, the extension opens a short setup wizard:
- Choose Local or Cloud mode.
- Enter and test the service URL.
- (Cloud) Sign in or create an account.
Local / self-hosted: classification needs an LLM provider. Open Settings → LLM Provider (in the web app, tick Self-hosted settings in the settings sidebar to reveal it), pick a provider, enter an API key if the provider needs one, and test the connection:
- Ollama — free, runs models on your own hardware.
- OpenRouter (recommended) — multi-model, pay-per-use. Best value with Llama 3.3 70B.
- OpenAI — GPT models.
- Anthropic — Claude models.
- Custom — any OpenAI-compatible endpoint.
See llm-providers.md for details and costs.
Basic Usage
- Save a bookmark: Right-click any page → “Save to Markcat”, or click the extension icon.
- View bookmarks: Open the extension’s new tab page or the web app.
- Browse categories: The left sidebar shows your category tree. Click to filter.
- Search: Use the search bar to find bookmarks by title, URL, or content.
- Edit: Click a bookmark to change its category, title, or notes.
