Recurring reminders

# Interval-based
kim add eye-break -I 30m -t "Eye Break" -m "Look away" -u critical
kim add water --every 1h

# Daily at a fixed time
kim add standup --at 10:00
kim add standup --at 10:00 --tz Asia/Kolkata

One-shot reminders

# Relative
kim remind "standup call" in 10m
kim remind "deploy window opens" in 2h 30m

# Absolute
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

# Urgency
kim remind "wake up!" in 5m --urgency critical

Fires once, runs in the background, frees your terminal immediately. Survives daemon restarts and reboots — stored in ~/.kim/oneshots.json.

Removing reminders

# Recurring — by name or index from `kim list`
kim remove water
kim remove 2

# One-shot — by index or message substring from `kim list -o`
kim remove 1 -o
kim remove "standup" -o

How it works

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

• Pure Python stdlib — zero runtime dependencies
• Single scheduler thread — all reminders share one heapq event loop (~0.02 MB flat)
• Atomic writes — all config and state files written via .tmp → rename
• Secrets never logged — Slack tokens and webhook URLs are not written to ~/.kim/kim.log
• Logs at ~/.kim/kim.log (5 MB rotating, 3 backups)

---

Uninstall

kim uninstall

Cancels pending one-shot reminders, removes autostart entries, deletes ~/.kim/ and the binary.

If kim is broken, use the standalone script:

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

Start small. Keep it in mind.
