Aggregaat.bot's answer:
Telegram has become an information platform, but it was built as a messenger. Following more than a handful of channels means checking each one separately, and there is no native way to filter or summarize across them. Aggregaat started as a fix for that: one feed from many channels, with keyword filters and scheduled AI digests.
Most tools in this space ask you to log in with your Telegram account so they can read channels as you. We chose the harder route: our own accounts subscribe to sources on our side, so your credentials never leave you. That now includes private channels, which you add with an invite link.
Aggregaat is built and maintained by a solo founder, and every user message is read and answered by a person.
