🧠 Synapse

Sync your Twitter/X bookmarks to Obsidian with AI-powered categorization.

What It Does

Fetches your Twitter bookmarks using the bird CLI
Diffs against previously processed bookmarks (only processes new ones)
Categorizes each tweet using Google Gemini AI
Saves as markdown files in your Obsidian vault, organized into smart folders

Features

📚 Automatic folder categorization using Gemini AI
🔄 Incremental sync (only processes new bookmarks)
📝 Rich markdown files with full metadata (likes, retweets, author, etc.)
🏷️ YAML frontmatter for Obsidian Dataview queries
⚡ Pagination support for efficient API usage
🔗 Direct links back to original tweets
🧹 Vault Organizer - Reorganize existing notes without re-fetching
🎨 Beautiful CLI - Interactive prompts, spinners, progress bars & colors

Prerequisites

1. Node.js 18+

node --version  # Should be v18 or higher

2. Twitter Authentication

Synapse includes the bird CLI automatically. Bird needs access to your Twitter session. The easiest way:

Log into x.com in Safari/Chrome/Firefox
Verify it works:
```
bird whoami
```

For more info on how to setup bird, visit here.

3. Gemini API Key

Get an API key from Google AI Studio

Installation

Option 1: Install from npm (recommended)

# Install globally
npm install -g @xorforce/synapse

# Now you can use the CLI commands anywhere
synapse --help
synapse-organize --help
synapse-likes --help

Option 2: Install via Homebrew (macOS)

brew tap xorforce/tap
brew install synapse

Option 3: Clone and run locally

# Clone the repo
git clone https://github.com/xorforce/synapse
cd synapse

# Install dependencies
npm install

# Run with npm scripts
npm run fetch
npm run organize

Configuration

Edit config.js to customize:

export default {
  // Path to your Obsidian vault
  vaultPath: '<your-vault-path-here>',
  
  // Folder inside vault for bookmarks
  bookmarksFolder: '<your-twitter-bookmarks-folder-name here>',
  
  // Fallback folder for uncategorizable tweets
  uncategorizedFolder: '<folder-name-for-unactegorized-entries>',
  
  // State file to track processed bookmarks
  stateFile: '<path-to-state-file here>',
  
  // Max pages to fetch (0 = unlimited, each page ~20 bookmarks)
  // For daily sync, 2-3 pages is usually enough
  maxPages: 2, // max page count
  
  // Gemini model for categorization
  geminiModel: 'gemini-2.0-flash',
  
  // Batch size for Gemini API (tweets per request, reduces API calls)
  batchSize: 10,
  
  // Max tweets to process per run (0 = unlimited)
  maxTweetsPerRun: 0,
  
  // Include visible metadata table in markdown (frontmatter always included)
  includeMetadataTable: true,
};

⚠️ Important: Always test synapse on an empty or dummy vault first before pointing it at your actual Obsidian vault. This ensures you understand how the tool organizes files and lets you verify everything works as expected without risking your real notes.

Usage

Set API Key

export GEMINI_API_KEY="your-api-key-here"

Run Sync (Daily)

npm run fetch

This fetches recent bookmarks (limited by maxPages in config, default ~40 bookmarks).

Full Sync (First Time / Catch Up)

npm run fetch:full

This fetches ALL bookmarks, ignoring the maxPages limit. Use this for:

First-time setup to import your entire bookmark history
Catching up after a long break
Re-syncing if you think you missed some

Dry Run (Preview Without Writing)

npm run dry-run          # Preview daily sync
npm run dry-run:full     # Preview full sync

Command Line Flags

Flag	Description
`--dry-run`	Preview mode - no files written, no state saved
`--full`	Fetch ALL bookmarks (ignore maxPages limit)

You can combine flags:

node src/index.js --dry-run --full

Reorganize Existing Vault

Already have a vault with notes that need better organization? Use the vault organizer with its beautiful interactive CLI:

npm run organize            # Interactive mode
npm run organize:dry-run    # Preview without moving files
npm run organize:bookmarks  # Organize bookmarks folder
npm run organize:likes      # Organize likes folder

Interactive CLI Experience

The organizer features a polished, user-friendly interface:

Markdown File Format

Each bookmark is saved as a markdown file with YAML frontmatter (for Obsidian Dataview) and optionally a visible metadata table.

Set includeMetadataTable: false in config for cleaner output (frontmatter is always kept).

Full format (default):

---
id: "1234567890"
author: "@username"
author_name: "Display Name"
created_at: "Mon Jan 05 12:00:00 +0000 2026"

Cron Job Setup (Daily Sync)

Option 1: crontab

crontab -e

Add (runs daily at 9 AM):

0 9 * * * cd /Users/bhagat/Desktop/bhagat/synapse && GEMINI_API_KEY="your-key" /usr/local/bin/node src/index.js >> /tmp/synapse.log 2>&1

Verify:

crontab -l

Option 2: launchd (macOS)

Create ~/Library/LaunchAgents/com.synapse.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.synapse</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/bin/node</string>
        <string>/Users/bhagat/Desktop/bhagat/synapse/src/index.js</string>
    </array>
    <key>EnvironmentVariables</key>
    <dict>
        <key>GEMINI_API_KEY</key>
        <string>your-api-key-here</string>
        <key>PATH</key>
        <string>/usr/local/bin:/usr/bin:/bin</string>
    </dict>
    <key>WorkingDirectory</key>
    <string>/Users/bhagat/Desktop/bhagat/synapse</string>
    <key>StartCalendarInterval</key>
    <dict>
        <key>Hour</key>
        <integer>9</integer>
        <key>Minute</key>
        <integer>0</integer>
    </dict>
    <key>StandardOutPath</key>
    <string>/tmp/synapse.log</string>
    <key>StandardErrorPath</key>
    <string>/tmp/synapse-error.log</string>
</dict>
</plist>

Load it:

launchctl load ~/Library/LaunchAgents/com.synapse.plist

How It Works

State Management

Processed bookmark IDs are stored in data/state.json
Only new bookmarks (not in state) are processed on each run
Delete data/state.json to reprocess everything

AI Categorization (Batch Processing)

Tweets are categorized in batches (default: 10 per API call) for efficiency:

40 tweets = 4 API calls instead of 40
~80% faster than individual requests
Reduces rate limiting issues

Gemini analyzes each batch and either:

Reuses an existing category folder if it fits
Creates a new category if none fit well

Categories are concise (2-4 words) and topic-focused like:

"AI Development"
"Swift Packages"
"Startup Advice"
"Web Development"
"Career Tips"

Pagination

Uses bird bookmarks --all --max-pages N for efficient fetching
Default: 2 pages (~40 bookmarks) - good for daily sync
Use npm run fetch:full or --full flag to fetch everything
Or set maxPages: 0 in config for always unlimited

Troubleshooting

"bird: command not found"

Bird is bundled with synapse. If you installed synapse globally, bird should be available. Try reinstalling:

npm install -g @xorforce/synapse
which bird

"Missing required credentials"

Bird can't find Twitter cookies. Either:

Log into x.com in Safari and grant Full Disk Access to Terminal
Set AUTH_TOKEN and CT0 environment variables manually

"GEMINI_API_KEY environment variable is required"

Set the API key before running:

export GEMINI_API_KEY="your-key"

Rate Limiting (429 errors)

Gemini has rate limits. The script handles this gracefully by:

Using "Uncategorized" folder for failed categorizations
Adding small delays between API calls

Reprocessing All Bookmarks

Delete the state file to start fresh:

rm -rf data/
npm run fetch

Obsidian Tips

Dataview Queries

With the YAML frontmatter, you can query your bookmarks:

TABLE author, likes, retweets
FROM "Twitter Bookmarks"
WHERE likes > 100
SORT likes DESC

Graph View

Enable backlinks to see connections between tweets in the same conversation.
