kim — keep in mind 🧠

Lightweight cross-platform reminder daemon for developers.
No UI. Config-driven. Runs in the background.

Documentation: https://pratikwayal01.github.io/kim/

Install

Linux / macOS

curl -fsSL https://raw.githubusercontent.com/pratikwayal01/kim/main/install.sh | bash

Windows (PowerShell — installs, fixes PATH, sets up autostart)

powershell -ExecutionPolicy Bypass -c "irm https://raw.githubusercontent.com/pratikwayal01/kim/main/install.ps1 | iex"

pip (all platforms — PATH must be configured manually on Windows, see below)

pip install kim-reminder

Windows + pip: After pip install, run this once to add kim to your PATH:

$p = python -c "import sysconfig; print(sysconfig.get_path('scripts','nt_user'))"
[Environment]::SetEnvironmentVariable("PATH",$env:PATH+";"+$p,"User")
$env:PATH += ";$p"

Then kim --version should work. Open a new terminal for the change to persist.

That's it. kim starts automatically on login.

Interval reminders

kim add "drink water" -I 30m          # every 30 minutes
kim add "drink water" --every 30m     # same — --every is an alias for -I
kim add "stretch" --every 1h

Daily at a fixed time

kim add standup --at 10:00                        # every day at 10:00 local time
kim add standup --at 10:00 --tz Asia/Kolkata      # with explicit timezone

One-shot reminders

# Relative
kim remind "standup call" in 10m
kim remind "take a break" in 1h
kim remind "check the oven" in 25m
kim remind "deploy window opens" in 2h 30m

# Absolute — fire at a specific time
kim remind "standup" at 10:00
kim remind "standup" at tomorrow 9am
kim remind "call" at friday 2pm
kim remind "deploy" at 2026-04-07 14:30 --tz America/New_York

Fires once, runs in the background, frees your terminal immediately.

Persistent — one-shot reminders survive daemon restarts and system reboots. Stored in ~/.kim/oneshots.json and loaded automatically when the daemon starts. Expired reminders are cleaned up on next startup.

Config — ~/.kim/config.json

{
  "reminders": [
    {
      "name": "eye-break",
      "interval": "30m",
      "title": "👁️ Eye Break",
      "message": "Look 20 feet away for 20 seconds. Blink slowly.",
      "urgency": "critical",
      "enabled": true
    },
    {
      "name": "water",
      "interval": "1h",
      "title": "💧 Drink Water",
      "message": "Stay hydrated.",
      "urgency": "normal",
      "enabled": true
    }
  ],
  "sound": true
}

Field	Values	Description
name	string	Unique identifier
interval	number or string ("30m", "1h", "1d")	How often to fire
title	string	Notification heading
message	string	Notification body
urgency	low / normal / critical	Notification priority
enabled	true / false	Toggle without deleting
sound	true / false	(top-level) Play sound globally
slack	object	(top-level) Slack settings

Per-Reminder Overrides

Each reminder can override global sound and Slack settings:

{
  "reminders": [
    {
      "name": "standup",
      "interval": "30m",
      "sound_file": "~/sounds/urgent.wav",
      "slack": {
        "enabled": true,
        "webhook_url": "https://hooks.slack.com/services/...",
        "channel": "#standup-alerts"
      }
    }
  ],
  "sound": true,
  "slack": {
    "enabled": true,
    "webhook_url": "https://hooks.slack.com/services/...",
    "channel": "#general"
  }
}

Or via CLI:

kim add standup -I 30m --sound-file ~/sounds/urgent.wav --slack-channel "#standup"

Slack Integration

{
  "reminders": [...],
  "sound": true,
  "slack": {
    "enabled": true,
    "webhook_url": "https://hooks.slack.com/services/your-webhook-id",
    "bot_token": "xoxb-your-bot-token",
    "channel": "#general"
  }
}

Use a Webhook or a Bot Token — not both. Test with kim slack --test.

How it works

Platform	Autostart	Notifications
Linux	systemd user service	notify-send
macOS	launchd agent	osascript
Windows	Task Scheduler	PowerShell toast

• Pure Python stdlib — no pip installs
• Zero config — works out of the box, creates default config on first run
• All reminders run on a single heapq scheduler thread — memory stays flat (~0.02 MB) regardless of how many reminders you have
• Logs at ~/.kim/kim.log, PID at ~/.kim/kim.pid
