curate

A personal information curation tool that automatically collects and organizes content from the web for your own use.

Overview

curate is designed around two axes of information gathering:

• Active collection (pick) - Manually triggered collection of specific content
• Passive collection - Automated periodic polling (planned)

Currently supports collecting X (Twitter) bookmarks with automatic media downloading, thread fetching, and Markdown export.

Features

• Fetches your X bookmarks via the official X API v2
• Downloads media (photos, videos, GIFs) with streaming support for large files
• Captures conversation threads automatically
• Exports each bookmark as a structured Markdown file with YAML frontmatter
• Tracks processed bookmarks in SQLite to avoid duplicates
• Automatic token refresh (OAuth 2.0 PKCE with offline access)
• Exponential backoff with jitter for API retries
• Rate limit detection and graceful handling
• Atomic file writes to prevent data corruption
• Structured JSON Lines logging with rotation
• macOS launchd integration for automated daily polling

Prerequisites

• Deno v2.0+
• An X Developer Account with a project/app configured:
  • OAuth 2.0 enabled (Confidential Client)
  • Callback URL set to http://localhost:8739/callback
  • Scopes: tweet.read, bookmark.read, users.read, offline.access

Setup

1. Clone and configure

git clone https://github.com/thedomainai/curate.git
cd curate
cp .env.example .env

Edit .env and fill in your X API credentials:

X_CLIENT_ID=     # Your OAuth 2.0 Client ID
X_CLIENT_SECRET=  # Your OAuth 2.0 Client Secret

2. Authenticate

cd x
deno task auth

This opens a browser window for OAuth authorization. After granting access, tokens are saved locally in storage/credentials/.

3. Fetch bookmarks

deno task poll

Bookmarks are saved as Markdown files in storage/output/x-bookmarks/.

4. (Optional) Automated polling with launchd

deno task install    # Register with launchd (runs daily at 09:00)
deno task status     # Check service status
deno task uninstall  # Remove from launchd

Run time can be customized via environment variables:

CURATE_RUN_HOUR=6 CURATE_RUN_MINUTE=30 deno task install

Configuration

Edit x/config/default.json to customize:

Key	Default	Description
polling.max_results_per_poll	100	Max bookmarks per poll
storage.output_dir	./storage/output	Output directory
logging.level	info	Log level (debug, info, warn, error)
logging.max_file_size_bytes	10485760	Log rotation threshold (10MB)
logging.retention_days	7	Log retention period
retry.max_attempts	3	Max retry attempts

Environment variable CURATE_OUTPUT_DIR can override the output directory.

Output Format
