Kaydet — Capture • Query • Remember

Your queryable personal database. Plain text storage, SQLite search, zero friction.

Kaydet is not a diary you read—it's a database you query. Capture thoughts, track work, log life—all from your terminal, in plain text.

Install

pip install git+https://github.com/miratcan/kaydet.git

Or with MCP support for AI integration:

pip install "git+https://github.com/miratcan/kaydet.git#egg=kaydet[mcp]"

The kaydet-mcp entry point stays installed, but it only becomes usable after installing this optional mcp extra.

Quick Start

# Capture a thought
kaydet "Fixed auth bug #work commit:abc123 time:2h status:done"

# Search by metadata
kaydet --filter "status:done"
kaydet --filter "time:>1"
kaydet --filter "commit:abc123"

# List all tags
kaydet --tags

# Open in editor
kaydet --editor

# Edit or delete by ID
kaydet --edit 42
kaydet --delete 42

Why Kaydet?

Zero Friction One command from your terminal. No app windows, no context switching, no loading screens.

Plain Text Forever Daily .txt files you can grep, version with git, sync however you like. No proprietary formats, no lock-in.

Entry Format

Entries are stored as plain text with this format:

• Timestamp and unique ID
• Message
• Metadata (key:value pairs)
• Tags (hashtags)

File Structure

~/.local/share/kaydet/
├── 2025-10-26.txt
├── 2025-10-27.txt
├── 2025-10-28.txt
└── index.db  (SQLite cache)

Metadata Queries

Kaydet parses key:value pairs and supports:

• Exact match: status:done, project:kaydet
• Numeric comparison: time:>2, time:>=1.5, time:<5
• Ranges: time:1..3 (between 1 and 3 hours)
• Duration parsing: 2h → 2.0, 90m → 1.5, 2.5h → 2.5

Configuration

Settings are in ~/.config/kaydet/config.ini:

[SETTINGS]
DAY_FILE_PATTERN = %Y-%m-%d.txt
DAY_TITLE_PATTERN = %Y/%m/%d - %A
LOG_DIR = ~/.local/share/kaydet
EDITOR = nvim
REMIND_AFTER_HOURS = 4
COLOR_HEADER = bold cyan
COLOR_TAG = bold magenta
COLOR_DATE = green
COLOR_ID = yellow

Color Customization

You can customize the colors of various elements in the output by adding the following settings under the [SETTINGS] section in config.ini:

[SETTINGS]
# ... existing settings ...
COLOR_HEADER = bold cyan
COLOR_TAG = bold magenta
COLOR_DATE = green
COLOR_ID = yellow

• COLOR_HEADER: Color for date separators and section headers.
• COLOR_TAG: Color for tags (e.g., #work).
• COLOR_DATE: Color for timestamps in search results.
• COLOR_ID: Color for entry IDs and pending todo counts.

You can use any Rich color string (e.g., red, bold green, rgb(255,100,0)).

AI Integration

Connect Kaydet to Claude Desktop via MCP:

// claude_desktop_config.json
{
  "mcpServers": {
    "kaydet": {
      "command": "kaydet-mcp"
    }
  }
}

Then ask Claude:

• "What did I work on this week?"
• "How consistent was my fitness routine last month?"
• "Summarize my accomplishments from last sprint"

Your AI assistant with perfect memory of your own data.

MCP Tools

• suggest_kaydet_tags – Suggest tags for assistants by reading .kaydet.tags in the current project or falling back to the directory name when no override is defined.

• Sync at Home protocol documents how the phone ↔ desktop LAN sync will work (SSID algılama, hash takası, append-both merge).

Cloud Sync & Mobile

Kaydet separates storage (plain text files) from index (SQLite database), making cloud sync simple and safe.

How it works

~/Documents/Kaydet/        → Synced (Google Drive, iCloud, Dropbox)
  ├── 2025-01-15.txt
  ├── 2025-01-16.txt
  └── ...

~/.local/share/kaydet/     → Local only (not synced)
  └── index.db

Why this works:

• Plain text files are the single source of truth
• Each device builds its own search index
• No conflicts, no corruption
• Zero infrastructure cost

Setup for cloud sync

1. First run — Kaydet will ask where to store entries:

   kaydet "First entry"
   
   # Choose your cloud folder:
   Path: ~/Google Drive/Kaydet

2. Change location later — Edit config and migrate:

   kaydet --config
   
   # Edit storage_dir in your editor
   # Kaydet will offer to move files automatically

3. On other devices — Install Kaydet, set same folder:

   kaydet "First entry on phone"
   Path: ~/Google Drive/Kaydet  # Same path

Supported cloud providers

• Google Drive (recommended for Android)
• iCloud Drive (recommended for iOS/macOS)
• Dropbox (cross-platform)
• Any folder sync (Syncthing, Resilio, etc.)

Note: Index is always local. Each device maintains its own index.db for fast search.
