Schedule

Group meeting scheduler with automatic optimal time confirmation.

Live: https://schedule.dalestudy.com

Features

• Dual deadlines — response deadline + event date range, so participants have time to check the confirmed schedule
• Natural language input — type availability in Korean (e.g., "다음주 화목 오후 2-6시 가능"), powered by Workers AI (Llama)
• Calendar grid — drag-select 30-min slots with timezone support
• Auto-confirmation — optimal time is confirmed when all respond or the deadline passes
• Link-based auth — no login required, share unique URLs per participant
