1. Does it handle topics?
In a group with topics, a summary of everything at once is noise. Look for per-topic summaries and a choice of where the nightly one goes. KeeperBots does both.
2. Can it answer questions, not just summarize?
Summaries cover a window. The question that matters is often older — what did we decide about the venue? KeeperBots answers from the whole history with /ask.
3. Can members opt out?
Your members didn't sign up for a bot. Anyone should be able to keep their messages out. In KeeperBots, /optout does that, and nobody has to announce it in the group.
4. Is your chat used to train AI?
Ask directly. KeeperBots sends messages to an AI provider only to write your summaries and doesn't use them to train any model.
5. Will it spam the group?
Look for limits. KeeperBots posts at most once every ten minutes on its own, and answers to members are capped per person and per day.
6. Can you leave with your data?
If it isn't for you, your history should come with you. KeeperBots exports the whole archive in one download.
The limit every bot shares
Telegram gives bots no message history. Any summary bot only sees messages sent after you add it.
