The bot delivers on its name, but the price of convenience is access to your own account. We would think twice before giving an unknown bot a way into Telegram. If you really need it, use a spare account.
The job here is narrow: pull files and posts from places where the channel or group owner has turned off copying and forwarding. The profile also mentions social networks, without naming which platforms are covered.
The key detail sits in the command list: logging in. To see protected content the way you see it, the bot has to sign in as you, and one command even offers to take a session string. That string is effectively a master key: whoever holds it can read your chats and act as you. Nothing in the description says who runs the bot.
On the plus side, logging out is supported and the menu language can be switched. Pricing and limits are not mentioned anywhere, so you only learn the terms after starting.
Then there is respect for creators. Forwarding is usually blocked for a reason: paid courses, exclusive posts, someone's hard work. Keeping a copy for yourself is one thing, reposting it is another, and that responsibility is yours.
