Send LeetCode Daily to Telegram
Delivers today's LeetCode Daily Challenge to your Telegram every weekday morning with the problem statement, approach hint, complexity, and key insight.
What It Does
Every weekday morning at 7 AM IST, this workflow fetches today's LeetCode Daily Challenge and delivers a structured problem brief to your Telegram. You get the problem name, difficulty, topic category, full problem statement in plain English, a worked example, the recommended algorithm approach (without spoiling the solution), time and space complexity for the optimal approach, and the single key insight that unlocks the problem.
Why It Matters
The most common reason people fall off their LeetCode practice is simply forgetting to start. You open your laptop, get pulled into work, and by evening the habit is broken again. This workflow flips that — the problem finds you at 7 AM before the day gets busy.
Every morning you see a problem brief waiting in Telegram. It takes 2 minutes to read, gives you an approach hint so you spend your time coding instead of guessing the technique, and builds daily consistency without any manual habit tracking.
How It Works
- Scheduled Trigger — Fires every weekday at 1:30 AM UTC (7:00 AM IST), timed to land in your Telegram before your morning routine ends.
- AI Agent with Internet Search — Searches LeetCode and developer community sources for today's published Daily Challenge, pulling problem details, examples, and editorial hints.
- Telegram Message — Delivers a clean, structured problem card to your chat with everything you need to start — no browser required.
