ContestWatcherBot is a Telegram bot that keeps track of all the major online programming contests. It sends you notifications one day and one hour before each event. Try it your self at https://t.me/contestwatcherbot

Unfortunately, we have stalled the development for this bot and are not merging pull requests. You are welcome to fork this project and apply any features you wish.

Currently we support the following websites:

• AtCoder
• Codechef
• Codeforces
• CS Academy
• TopCoder

You can choose which notifications you will receive by enabling/disabling each website. Use /help for more information.

Since Codeforces has a very nice API we can keep track not only of the upcoming contests but also of system testing and rating changes. You can add your Codeforces handle to the bot and it will notify you about system testing and rating changes of the contests that you took part. Use /help_handles for more information.

We gladly accept contributions! We plan to write better documentation for the code, but if you feel like you can contribute, you are very welcome to do so :-)
