Technical Assignment: Telegram Bot for Parsing Messages and Profiles

1. Project Goal

Create a Telegram bot that allows collecting data from other people's chats and groups, filtering participants and messages by various criteria, tracking user statuses, and providing advanced features for analysis and sorting.

2. Functional Capabilities

2.1. Message Parsing

• Searching for messages in other groups by keywords.

• Filtering messages by date, content type (text, media, links).

• The ability to save found messages in a database or CSV/Excel.

• Setting up notifications when messages with keywords appear.

2.2. Participant Parsing

• Obtaining a list of participants from other groups.

• Filtering by activity status:

  • Online now

  • Recently online (for example, 10–60 minutes ago)

  • Long time ago online (for example, more than a day)

• The ability to mark users as premium/non-premium.

• The ability to collect user avatars.

• Support for filters by other criteria, such as having a biography, phone number (if available).

2.3. Bot Status Management

• Displaying the bot's status (for example, online, inactive, parsing).

• Setting time intervals when the bot is active.

• The ability to change statuses in bulk for selected users.

2.4. Interface and Management

• User-friendly control panel via Telegram commands or built-in web interface.

• The ability to configure multiple projects/groups simultaneously.

• The ability to choose which functions are active: only messages, only participants, or everything together.

• The ability to export data to CSV/Excel for further analysis.

2.5. Additional Features

• Sorting users by activity, number of messages, avatar.

• Highlighting "interesting" messages (for example, by keywords or frequency of mentions).

• The ability to automatically generate reports on user activity.

• Setting up premium features: advanced search, quick export, access to more than 1 foreign group simultaneously.

3. Security Requirements

• Using the official Telegram API.

• Storing user data in an encrypted database.

• Secure authorization for access to the bot's functionality.

• Logging bot actions without disclosing personal information of users.

4. Platform Requirements

• The bot runs on Python (aiogram/telethon) or Node.js (telegraf/gram.js).

• The ability to host on a server that supports cron jobs for regular parsing.

• Support for scalability (many groups and users).
