The free version is good for testing out ChipBot. You can get by but you'll have to choose your answers wisely.
If your website is a blog, e-commerce store, or provides services, you'll want to upgrade to the paid tier. You won't be capped with answers or notifications. This is ideal to provide good support, collect good feedback, and get actionable reports.
CEO of ErgoImpact.com says he's more successful, saves more time, and understands his customers more with ChipBot.
