Once I added a bot to my website, but only to find out it was not free as it advertised :)
Now after a while without, I refreshed it and it does have a bot again accessible from the text collection as well: https://poe.com/tambetvali.
Among other bots, SpireasonWebsite bot is able to answer the questions about my base text collection; other bots are specific to some topic and have different sources.
