Want to give away a prize to your subscribers without spreadsheets and random number sites? TgGrow gets it done in a couple of minutes. We like that contests and tools sit in one list so nothing gets lost. Which parts are paid only becomes clear in the payment section.
A Telegram giveaway usually goes like this: a post, a join button and a random winner at the end. TgGrow takes over all of that. The new command sets up a contest, and the all command lists everything you've already launched.
Besides contests, the bot offers what it calls tools for growing a channel. The profile doesn't explain what they are, but you create them from the same menu. You can also attach your own bots, probably so the giveaway runs under your name rather than TgGrow's.
Money: there's a pay command covering access and payment, so some features cost something. Whether a basic contest is free isn't stated; check before you announce a giveaway to your readers.
The interface starts in English and a command switches it, Russian included. Questions and bug reports go to a dedicated support account linked in the bot's profile.
